Description

The present invention relates to a box with a shock-absorbing device.

Conventionally, a clamping type packaging container shown in Patent Document 1 has existed as a packaging container with a cushioning device. The clamping type packaging container P in Patent Document 1 consists of a box body 1 and a pair of upper and lower inner stacking bodies 3, and the inner stacking bodies 3 have a clamping wall 5, a pair of left and right side flaps 13, and a pair of front and rear side flaps 15, and the clamping wall 5 has cuts 17a, 17b formed therein, allowing the clamping wall 5 to be elastically deformable. When the clamping type packaging container P is used, an article is held between the pair of clamping walls 5 by placing the upper and lower inner stacking bodies 3 in the box body 1.

Another example of a conventional packaging container with a cushioning device is shown in FIG. 5(c) of Patent Document 2, in which folding pieces G are provided to protrude from the left and right sides of a plate E, and an item C is supported by a flexible film H with an end fixed to the folding pieces G, and the folding pieces G are folded toward the item C to serve as a storage guide means for the storage container I and a removal means for removing the item.

However, in the clamping type packaging container of Patent Document 1, a pair of inner stacks 3 are provided, which means that the number of cushioning devices is large, which increases costs, and in addition, in order to package the stored item, the item must be sandwiched between the inner stacks 3, which is time-consuming.

On the other hand, in the case of FIG. 5(c) of Patent Document 2, the cushioning device is made up of only one plate-like member consisting of a plate body E and a folded piece G, and a flexible film, so the number of cushioning devices is small. However, it is necessary to fix a flexible film H covering the item C to the plate-like member, and store the item C fixed by the plate-like member and the flexible film in the storage container I, which makes packaging the stored items time-consuming, and furthermore, the use of a flexible film means that it cannot contribute to eliminating the use of plastic.

When the box body 8 is assembled, the fold-in pieces 32, 42 are sandwiched between the outer front portion 14 and the inner front portion 18.

The flap portion 60 and the flap portion 70 have a generally trapezoidal shape that narrows toward the tip. The glue tab portion 52 and the glue tab portion 54 also have a generally trapezoidal shape that narrows toward the tip, with the glue tab portion 52 being adhered to the inner surface of the right side portion 30 and the glue tab portion 54 being adhered to the inner surface of the left side portion 40.

In the box body 8, the vertical length L12 of the outer front portion 14, the vertical length L30 of the right side portion 30, the vertical length L40 of the left side portion 40, and the vertical length L50 of the back portion 50 are formed to be approximately the same length, and in particular, the length L30 and the length L40 are formed to be the same length.

The folding line K1 on the right side surface 30 and the flap portion 60 and the folding line K2 on the left side surface 40 and the flap portion 70 are for folding the box body 7. In other words, when folded at the lines K1 and K2, the lines K1 and K2 form a valley fold when viewed from the outside of the box body 8. The glue tab 52 is adhered to the area on the inner surface of the right side surface 30 that is closer to the rear side than the line K1, and the glue tab 54 is adhered to the area on the inner surface of the left side surface 40 that is closer to the rear side than the line K2.

Next, the lid portion 80 has a lid portion main body 81 connected to the side of the rear portion 50 opposite the bottom surface portion 10 via a fold line, and an insertion portion 90 connected to the lid portion main body 81.

The lid body 81 has a lid plate portion 82 connected to the rear portion 50, band portions 83 and 85 connected to the left and right side portions of the lid plate portion 82 via fold lines, a folded portion 84 connected to the side portion of the band portion 83 opposite the lid plate portion 82 via a fold line, and a folded portion 86 connected to the side portion of the band portion 85 opposite the lid plate portion 82 via a fold line, and the folded portions 84 and 86 are bonded to the inside surface of the lid plate portion 82.

The insertion portion 90 is connected to the side of the cover plate portion 82 opposite the back surface portion 50 via a fold line, and has a band-shaped portion 92 connected to the cover plate portion 82, a band-shaped portion 94 connected to the band-shaped portion 92 via a cut line 92K, and an insertion piece portion 96 connected to the band-shaped portion 94 via a cut line 94K.

The cut lines 92K, 94K are formed in a direction parallel to the fold line between the cover plate portion 82 and the insertion portion 90, and by grasping the end of the band portion 94 (the end on the left side surface) and pulling it toward the right side surface, the cut lines 92K, 94K break and the band portion 94 is removed.

In addition, a gap is formed between the left and right end regions of the insertion piece 96 and the band-shaped portion 94, so that the insertion piece 96 has a base end 96a that is narrow in the left-right direction and a tip end 96b that is wide in the left-right direction.

The left-right length of the base end 96a is approximately the same as or slightly shorter than the left-right length of the opening 22, and the left-right length of the tip end 96b is longer than the left-right length of the opening 22 and is approximately the same as or shorter than the left-right length of the entire inserted portion 20 including the pair of notches 24. This prevents the tip end 96b from coming out of the inserted portion 20 when the insertion piece 96 (particularly the tip end 96b) is inserted into the inserted portion 20.

When the box body 7 is assembled, it is configured as shown in FIG. 4. When the box body 7 is assembled, the protrusions 18a, 18b fit into the notches 10a, 10b, and the inner front part 18 is inside the outer front part 14, and the inner front part 18 is approximately parallel to the outer front part 14. The folded pieces 32, 42 are folded in half and sandwiched between the inner front part 18 and the outer front part 14. The glue tab 52 is glued to the inside of the right side part 30, and the glue tab 54 is glued to the inside surface of the left side part 40. As a result, the front part 12 (particularly the outer front part 14 and the inner front part 18), the right side part 30, the left side part 40, and the back part 50 are erected at a right angle (or approximately a right angle) to the bottom part 10. The folded parts 84, 86 are glued to the inside surface of the cover plate part 82.

Although the box 7 has been described as having the above configuration, the box may have a box body and a lid that opens and closes relative to the box body, and the box body may have a bottom, a front, a right side, a left side, a back, a flap connected to the side of the right side opposite the bottom, and a flap connected to the side of the left side opposite the bottom.

The lid closing mechanism does not have to be configured to insert the insertion piece 96 into the inserted part 20 as described above. For example, it may be configured so that a piece connected to the edge of the cover plate part 82 on the side opposite the back part 50 is inserted along the inner surface of the inner front part 18 of the front part 12.

The lid may be connected to the front portion, or may be connected to both the front portion and the rear portion. In other words, the lid may be provided from at least one of the side portions opposite the bottom portion of the front portion and the side portions opposite the bottom portion of the rear portion.

Next, the cushioning device 100 (the cushioning device of Example 1) is configured as shown in Figs. 1 to 3, and has a main body 102 and raised portions 103, 104, 105, and 106 that are connected to each side of the main body 102 via fold lines M1 to M4. The cushioning device 100 is formed entirely from a single sheet-like blank (specifically, a blank made of cardboard (e.g., thin cardboard), but may also be a blank made of other paper such as a cardboard blank). Note that Figs. 1 to 3 are the same figure, and are explained separately in multiple figures in order to indicate the reference numerals.

Here, the main body 102 has a square (specifically, rectangular) outer shape, the front side edge (first side edge) Ha and the rear side edge (fourth side edge) Hd of the main body 102 are parallel to each other, the right side edge (second side edge) Hb and the left side edge (third side edge) Hc of the main body 102 are parallel to each other, and adjacent sides in the sides Ha to Hd are at right angles to each other. In other words, the sides Ha and Hd are formed in the left-right direction, and the sides Hb and Hc are formed in the front-rear direction. As a result, the length of the front side edge Ha of the main body 102 is the same as the length of the rear side edge Hd, and the length of the right side edge Hb and the left side edge Hd are the same. The sides Ha, Hb, Hc, and Hd of the main body 102 are sides along the folded lines between the rising parts 103 to 106 of the main body 102.

The length L1 between side Hb and side Hc of the main body 102 is formed to be approximately the same as the length L11 between side 10b on the right side and side 10c on the left side of the bottom surface 10 of the box main body 8 (strictly speaking, length L1 is slightly shorter than length L11), and the length L2 between side Ha and side Hd of the main body 102 is formed to be approximately the same as the length L12 between side 10a on the front side and side 10d on the back side of the bottom surface 10 of the box main body 8 (strictly speaking, length L2 is slightly shorter than length L12), As a result, when the cushioning device 100 is stored in the box body 8, the outer surface of the raised portion 103 contacts the inner front portion 18 while aligning with the inner surface of the inner front portion 18, the outer surface of the raised portion 104 contacts the right side portion 30 while aligning with the inner surface of the right side portion 30, the outer surface of the raised portion 105 contacts the left side portion 40 while aligning with the inner surface of the left side portion 40, and the outer surface of the raised portion 106 contacts the rear portion 50 while aligning with the inner surface of the rear portion 50. In other words, the raised portion 103 is approximately parallel to the inner front portion 18, the raised portion 104 is approximately parallel to the right side portion 30, the raised portion 105 is approximately parallel to the left side portion 40, and the raised portion 106 is approximately parallel to the rear portion 50.

In addition, multiple circumferential discontinuous cuts (hereinafter simply referred to as "circumferential cuts") 110-170 are formed in the main body 102. Note that the term "circumferential discontinuous cuts" refers to multiple cuts formed in a circumferential shape with seams between them, and thus the cuts are discontinuous around the circumference, hence the word "discontinuous."

That is, the circumferential cuts 110 to 170 are formed concentrically, with the diameters decreasing from the outside to the inside in the order of circumferential cuts 110, 120, 130, 140, 150, 160, and 170. The cuts in the shock absorber 100 penetrate from the front surface to the back surface (the same applies to shock absorbers 200 to 300').

The circumferential cut 110 includes a cut 111 formed on the corner (front right corner) of the front and right side of the main body 102, a cut 113 formed on the corner (rear right corner) of the back and right side of the main body 102, a cut 115 formed on the corner (rear left corner) of the back and left side of the main body 102, and a cut 117 formed on the corner (front left corner) of the front and left side of the main body 102.

The cut 111 has a linear cut (first cut) A formed in the left-right direction, a linear cut (third cut) B connected to cut A and inclined in the left-right direction (specifically, inclined at 45 degrees in the left-right direction), and a cut (second cut) C connected to cut B and formed in the front-to-back direction, and has an overall shape that is bent in a roughly hook-like shape.

In addition, the cut 113 has a linear cut A formed in the left-right direction, a linear cut B connected to cut A and inclined in the left-right direction (specifically, inclined at 45 degrees in the left-right direction), and a cut C connected to cut B and formed in the front-back direction, and has an overall shape that is bent in a roughly hook-like shape.

In addition, the cut 115 has a linear cut A formed in the left-right direction, a linear cut B connected to cut A and inclined in the left-right direction (specifically, inclined at 45 degrees in the left-right direction), and a cut C connected to cut B and formed in the front-back direction, and has an overall shape that is bent in a roughly hook-like shape.

In addition, the cut 117 has a linear cut A formed in the left-right direction, a linear cut B connected to cut A and inclined in the left-right direction (specifically, inclined at 45 degrees in the left-right direction), and a cut C connected to cut B and formed in the front-to-back direction, and has an overall shape that is bent in a roughly hook-like shape.

The notch C of the notch 111 and the notch C of the notch 113 are on the same straight line, and a seam 112 without a notch is formed between the notch C of the notch 111 and the notch C of the notch 113. In other words, the seam 112 is formed along a straight imaginary line between the two notches C.

Similarly, the cut A of cut 113 and the cut A of cut 115 are on the same straight line, and a seam 114 without a cut is formed between the cut A of cut 113 and the cut A of cut 115. In other words, the seam 114 is formed along a straight imaginary line between the two cuts A.

Similarly, the cut C of cut 115 and the cut C of cut 117 are on the same straight line, and a seam 116 without a cut is formed between the cut C of cut 115 and the cut C of cut 117. In other words, the seam 116 is formed along a straight imaginary line between the two cuts C.

Similarly, the notch A of the notch 117 and the notch A of the notch 111 are on the same straight line, and a seam 118 where no notch is formed is formed between the notch A of the notch 117 and the notch A of the notch 111. In other words, the seam 118 is formed along a straight imaginary line between the two notches A.

As described above, the notches 111, 113, 115, and 117 are formed on a circumferential virtual line, and the notches and seams are formed alternately along the circumferential virtual line, so that the multiple notches 111, 113, 115, and 117 are formed circumferentially via the seams 112, 114, 116, and 118.

The circumferential cut 120 also has a linear cut 121 formed on the right side, a linear cut 123 formed on the back side, a linear cut 125 formed on the left side, and a linear cut 127 formed on the front side.

A seam 122 without a cut is formed between the cuts 121 and 123. In other words, the seam 122 is formed along a straight imaginary line (i.e., an imaginary line inclined with respect to the left-right and front-back directions) between the end of the cut 121 (the end on the rear side) and the end of the cut 123 (the end on the right side).

Similarly, a seam 124 without a cut is formed between the cuts 123 and 125. In other words, the seam 124 is formed along a straight imaginary line (i.e., an imaginary line inclined with respect to the left-right and front-back directions) between the end of the cut 123 (the end on the left side) and the end of the cut 125 (the end on the back side).

Similarly, a seam 126 without a cut is formed between the cuts 125 and 127. In other words, the seam 126 is formed along a straight imaginary line (i.e., an imaginary line inclined with respect to the left-right and front-back directions) between the end of the cut 125 (the end on the front side) and the end of the cut 127 (the end on the left side).

Similarly, a seam 128 without a cut is formed between the cut 127 and the cut 121. In other words, the seam 128 is formed along a straight imaginary line (i.e., an imaginary line inclined with respect to the left-right and front-rear directions) between the end of the cut 127 (the end on the right side) and the end of the cut 121 (the end on the front side).

As described above, the seams 122, 124, 126, and 128 are formed along imaginary lines that are inclined relative to the left-right and front-rear directions, and the cuts 121, 123, 125, and 127 are formed on a circumferential imaginary line, with the cuts and seams alternately formed along the circumferential imaginary line, and the multiple cuts 121, 123, 125, and 127 are formed circumferentially via the seams 122, 124, 126, and 128.

The circumferential cut 130 has a substantially similar configuration to the circumferential cut 110, except that the size of the circumferential imaginary line is different (i.e., the circumferential cut 130 is substantially similar in shape to the circumferential cut 110), and is formed in the following order along the circumferential imaginary line: cut 131, seam 132, cut 133, seam 134, cut 135, seam 136, cut 137, and seam 138. In other words, the cuts 131, 133, 135, and 137 are formed on the circumferential imaginary line, and the cuts and seams are alternately formed along the circumferential imaginary line, and the multiple cuts 131, 133, 135, and 137 are formed circumferentially via the seams 132, 134, 136, and 138.

All of the cuts 131, 133, 135, and 137 have cuts A, B, and C, where cut A is a linear cut formed in the left-right direction, cut B is a linear cut inclined in the left-right direction (specifically, inclined at 45 degrees in the left-right direction), and cut C is a linear cut formed in the front-rear direction.

In addition, the circumferential cut 140 has a substantially similar configuration to the circumferential cut 120, except that the size of the circumferential imaginary line is different (i.e., the circumferential cut 140 has a substantially similar shape to the circumferential cut 120). The circumferential cut 140 has a linear cut 141 formed on the right side, a linear cut 143 formed on the back side, a linear cut 145 formed on the left side, and a linear cut 147 formed on the front side. The joint 142 between the cuts 141 and 143 and the joint 144 between the cuts 141 and 143 are also different. The seam 144 between 43 and cut 145, the seam 146 between cut 145 and cut 147, and the seam 148 between cut 147 and cut 141 are formed along imaginary lines inclined with respect to the left-right and front-back directions, and the cuts 141, 143, 145, and 147 are formed on a circumferential imaginary line, and the cuts and seams are formed alternately along the circumferential imaginary line, with the multiple cuts 141, 143, 145, and 147 being formed circumferentially via the seams 142, 144, 146, and 148.

The circumferential cut 150 has a substantially similar configuration to the circumferential cuts 110 and 130, except that the size of the circumferential imaginary line is different (i.e., the circumferential cut 150 is substantially similar in shape to the circumferential cuts 110 and 130), and is formed in the following order along the circumferential imaginary line: cut 151, seam 152, cut 153, seam 154, cut 155, seam 156, cut 157, and seam 158. In other words, the cuts 151, 153, 155, and 157 are formed on the circumferential imaginary line, and the cuts and seams are alternately formed along the circumferential imaginary line, and the multiple cuts 151, 153, 155, and 157 are formed circumferentially via the seams 152, 154, 156, and 158.

All of the cuts 151, 153, 155, and 157 have cuts A, B, and C, where cut A is a linear cut formed in the left-right direction, cut B is a linear cut inclined in the left-right direction (specifically, inclined at 45 degrees in the left-right direction), and cut C is a linear cut formed in the front-rear direction.

In addition, the circumferential cut 160 has a substantially similar configuration to the circumferential cuts 120 and 140, except that the size of the circumferential imaginary line is different (i.e., the circumferential cut 160 has a substantially similar shape to the circumferential cuts 120 and 140). The circumferential cut 160 has a linear cut 161 formed on the right side, a linear cut 163 formed on the back side, a linear cut 165 formed on the left side, and a linear cut 167 formed on the front side. The seam 162 between the cuts 161 and 163, The seam 164 between the cuts 163 and 165, the seam 166 between the cuts 165 and 167, and the seam 168 between the cuts 167 and 161 are formed along imaginary lines that are inclined with respect to the left-right and front-back directions, and the cuts 161, 163, 165, and 167 are formed on a circumferential imaginary line, and the cuts and seams are formed alternately along the circumferential imaginary line, with the multiple cuts 161, 163, 165, and 167 being formed circumferentially via the seams 162, 164, 166, and 168.

The circumferential cut 170 has a substantially similar configuration to the circumferential cuts 110, 130, and 150, except that the size of the circumferential imaginary line is different (i.e., the circumferential cut 170 is substantially similar in shape to the circumferential cuts 110, 130, and 150), and is formed along the circumferential imaginary line in the following order: cut 171, seam 172, cut 173, seam 174, cut 175, seam 176, cut 177, and seam 178. In other words, the cuts 171, 173, 175, and 177 are formed on the circumferential imaginary line, and the cuts and seams are alternately formed along the circumferential imaginary line, and the multiple cuts 171, 173, 175, and 177 are formed circumferentially via the seams 172, 174, 176, and 178.

All of the cuts 171, 173, 175, and 177 have cuts A, B, and C, where cut A is a linear cut formed in the left-right direction, cut B is a linear cut inclined in the left-right direction (specifically, inclined at 45 degrees in the left-right direction), and cut C is a linear cut formed in the front-rear direction. The central region 102-1, which is the region surrounded by the peripheral imaginary line in the circumferential cut 170, is located in the center of the main body 102.

In addition, among the circumferential cuts 110 to 170, the circumferential cuts 110, 130, 150, and 170 are first-type circumferential discontinuous cuts (hereinafter referred to as "first-type circumferential cuts"), and the circumferential cuts 120, 140, and 160 are second-type circumferential discontinuous cuts (hereinafter referred to as "second-type circumferential cuts"). In other words, the multiple circumferential cuts 110 to 170 are composed of multiple first-type circumferential cuts and multiple second-type circumferential cuts (i.e., the multiple circumferential cuts 110 to 170 include multiple first-type circumferential cuts and multiple second-type circumferential cuts), and the first-type circumferential cuts and the second-type circumferential cuts are alternately provided from the outside to the inside. In addition, each of the circumferential cuts 110, 130, 150, and 170 (cuts 111, 113, 115, 117, 131, 133, 135, 137, 151, 153, 155, 157, 171, 173, 175, and 177) corresponds to a corner-side cut provided on the four corner sides of the main body 102.

In addition, in the circumferential cuts 120, 140, and 160, the cuts 123, 127, 143, 147, 163, and 167 correspond to linear fourth cuts parallel to the side portion (first side portion) Ha, and the cuts 121, 125, 141, 145, 161, and 165 correspond to linear fifth cuts parallel to the side portion (second side portion) Hb, and in each of the circumferential cuts 120, 140, and 160, a pair of fourth cuts and a pair of fifth cuts are provided.

Furthermore, in the above-mentioned circumferential cuts 110, 130, 150, and 170, cut A corresponds to the first cut, cut B corresponds to the third cut, and cut C corresponds to the second cut.

In addition, each of the circumferential cuts 110, 130, 150, and 170 is an angle side cut provided on the four corner sides of the main body portion 102.

The circumferential cuts 110 to 170 are formed as described above, and in the circumferential cuts 110 to 170, multiple cuts and seams are formed along a circumferential imaginary line, and the imaginary lines in the circumferential cuts 110 to 170 are formed concentrically, but the imaginary lines are formed so that the diameter gradually decreases from the circumferential cut 110 to the circumferential cut 170.

In the above circumferential cuts 110 to 170, the directions of cuts A are parallel to each other, the directions of cuts C are parallel to each other, and further, the directions of cuts B in cuts 111, 131, 151, 171, 115, 135, 155, and 175 are parallel to each other, and the directions of cuts B in cuts 113, 133, 153, 173, 117, 137, 157, and 177 are parallel to each other.

In addition, in the cuts that make up the circumferential cuts 110 to 170, a short length of joint may be provided midway through the cuts to prevent the main body 102 from becoming mesh-like due to a slight impact before the cushioning device 100 is used (the same applies to the other cushioning devices 200, 300, 300').

As described above, in each of the multiple circumferential cuts 110 to 170, the multiple cuts are formed along a circumferential imaginary line via a seam. In addition, the diameter of the peripheral imaginary line differs in each circumferential cut, and the imaginary lines in the multiple circumferential cuts are formed concentrically.

In addition, in the case of two adjacent circumferential cuts, a first circumferential discontinuous cut (hereinafter referred to as the "first circumferential cut") and a second circumferential discontinuous cut (hereinafter referred to as the "second circumferential cut"), which are disposed through a certain circumferential cut, a target circumferential cut is provided between the seam of the first circumferential cut and the seam of the second circumferential cut, and the target cut is provided between the cut continuing from the seam of the first circumferential cut and the cut continuing from the seam of the second circumferential cut, so that a detour is provided between the two seams to bypass the straight line path between the two seams.

For example, when the circumferential cut 120 is the target circumferential cut, the circumferential cut (first circumferential cut) 110 and the circumferential cut (second circumferential cut) 130 are adjacent to each other with the circumferential cut 120 in between, and the cut (target cut) 127 of the circumferential cut 120 is provided between the seam 118 and the seam 138, and the cut A (cut 117) is provided between the seam 118 of the circumferential cut (first circumferential cut) 110 and the seam 118 of the circumferential cut (first circumferential cut) 110. A cut (target cut) 127 is provided between the cut A (cut A1) of the first circumferential cut (second circumferential cut) 130 and the cut A (cut A of cut 137 (cut A2)) continuing from the seam 138 of the circumferential cut (second circumferential cut) 130 (i.e., three cuts are formed side by side), so that a detour S2 is provided between the seams 118 and 138 that bypasses the straight path S1 between the seams 118 and 138.

As a result, when the sheet-like cushioning device 100 is placed over the stored item, as shown in FIG. 12, the region R1 between the cut 127 and the cut A1 is inclined relative to the region R2 along the seam 118, and the region R3 between the cut 127 and the cut A2 is inclined relative to the region R4 along the seam 138, resulting in a vertical gap between the regions R2 and R4.

In addition, for example, when the circumferential cut 120 is the target circumferential cut, the circumferential cut (first circumferential cut) 110 and the circumferential cut (second circumferential cut) 130, which are two adjacent circumferential cuts sandwiching the circumferential cut 120 therebetween, have a cut (target cut) 125 of the circumferential cut 120 between the seam 116 and the seam 136, and a cut C (cut) continuing from the seam 116 of the circumferential cut (first circumferential cut) 110. A cut (target cut) 125 is provided between the cut C (cut C1) of 117 and the cut C (cut C of 137 (cut C2)) continuing from the seam 136 of the circumferential cut (second circumferential cut) 130 (i.e., three cuts are formed side by side), so that a detour is provided between the seams 116 and 136 that bypasses the straight path of the seams 116 and 136.

For example, when the circumferential cut 130 is the target circumferential cut, the circumferential cut (first circumferential cut) 120 and the circumferential cut (second circumferential cut) 140 are adjacent to each other with the circumferential cut 130 in between, and the cut (target cut) 137 of the circumferential cut 130 is provided between the seam 126 and the seam 146, and the cut (target cut) C (cut C of the cut 137) is provided at a position between the cut 125 continuing from the seam 126 of the circumferential cut (first circumferential cut) 120 and the cut 145 continuing from the seam 146 of the circumferential cut (second circumferential cut) 140 (i.e., three cuts are formed side by side), so that a detour is provided between the seam 126 and the seam 146 to bypass the straight path of the seam 126 and the seam 146.

For example, when the circumferential cut 130 is the target circumferential cut, the circumferential cut (first circumferential cut) 120 and the circumferential cut (second circumferential cut) 140 are adjacent to each other with the circumferential cut 130 in between, and the cut (target cut) 137 of the circumferential cut 130 is provided between the seam 126 and the seam 146, and the cut (target cut) A (cut A of the cut 137) is provided at a position between the cut 127 continuing from the seam 126 of the circumferential cut (first circumferential cut) 120 and the cut 147 continuing from the seam 146 of the circumferential cut (second circumferential cut) 140 (i.e., three cuts are formed side by side), so that a detour is provided between the seam 126 and the seam 146 to bypass the straight line path of the seam 126 and the seam 146.

As a result, when the sheet-like cushioning device 100 is placed over the stored item, the area between the cut 125 and the cut C1 is inclined relative to the area along the seam 116, and the area between the cut 125 and the cut C2 is inclined relative to the area along the seam 136, so that there is a gap between the area along the seam 116 and the area along the seam 136 in the vertical direction.

In this way, the area along the seam remains horizontal, while the area between the two cuts is inclined, so that the cushioning device 100 is deformed into a three-dimensional mesh shape when placed over the item to be stored.

In addition, the length of the side Ha on the front side and the side Hd on the back side of the main body 102 are formed to be the same as (or slightly shorter than) the length of the side 10a on the front side and the side 10d on the back side of the bottom surface 10 of the box body 7, and the length of the side Hb on the right side and the side Hc on the left side of the main body 102 are formed to be the same as (or slightly shorter than) the length of the side 10b on the right side and the side 10c on the left side of the bottom surface 10 of the box body 7. As a result, the cushioning device 10 can be placed in a position where the raised portions 103 to 106 are raised relative to the main body 102. When the box body 8 is stored in the state where the raised portion 103 is in contact with the inside of the inner front portion 18 along the inside surface of the inner front portion 18, the raised portion 104 is in contact with the inside of the right side portion 30 along the inside surface of the right side portion 30, the raised portion 105 is in contact with the inside of the left side portion 40 along the inside surface of the left side portion 40, and the raised portion 106 is in contact with the inside of the back portion 50 along the inside surface of the back portion 50.

Next, the rising portion (third rising portion) 103 is connected to the side portion on the front side of the main body portion 102 via a fold line, and is formed into a trapezoidal shape whose horizontal length becomes shorter toward the tip side. In the rising portion 103, the side portion J3a (which may be the fold line M1) on the main body portion 102 side and the side portion J3b on the tip side are parallel to each other.

The raised portion (first raised portion) 104 is connected to the side portion on the right side surface of the main body portion 102 via a fold line, and is formed in a generally trapezoidal shape whose horizontal length decreases toward the tip side. In the raised portion 104, the side portion J4a (which may be the fold line M2) on the main body portion 102 side and the side portion J4b on the tip side are parallel to each other. Furthermore, a recess is provided in the side portion J4b on the tip side.

The raised portion (second raised portion) 105 is connected to the side portion on the left side surface of the main body portion 102 via a fold line, and is formed in a generally trapezoidal shape whose horizontal length decreases toward the tip side. In the raised portion 105, the side portion J5a (which may be the fold line M3) on the main body portion 102 side and the side portion J5b on the tip side are parallel to each other. Furthermore, a recess is provided in the side portion J5b on the tip side.

In this way, because recesses are provided in the sides J4b and J5b, when pushing the cushioning device 100 downward with the raised portions 104 and 105 raised relative to the main body portion 102, the thumb can be placed in the recess to push the cushioning device 100 downward.

The raised portion (fourth raised portion) 106 is connected to the side on the back side of the main body 102 via a fold line, and is formed into a trapezoidal shape whose horizontal length decreases toward the tip. In the raised portion 106, the side J6a (which may be the fold line M4) on the main body 102 side and the side J6b on the tip side are parallel to each other.

In addition, in the rising portions 103 to 106, the length between the side portions on the main body 102 side and the side portions on the tip side are formed to be the same. In other words, the length La between the side portions J3a and J3b, the length Lb between the side portions J4a and J4b, the length Lc between the side portions J5a and J5b, and the length Ld between the side portions J6a and J6b are formed to be the same. Note that the lengths La to Ld are the lengths in the direction perpendicular to the side portions on the main body 102 side and the side portions on the tip side of the rising portions 103 to 106 (the same applies to the cushioning devices 200, 300, and 300').

The lengths La, Lb, Lc, and Ld are also formed to be the same (or may be approximately the same) as the lengths L30 and L40 of the box 7, so that when the raised portions 103-106 are raised relative to the main body 102 and stored in the box 7, and the lid portion 80 is closed, the flap portions 60 and 70 come into contact with the upper ends of the raised portions 104 and 105, and the cushioning device 100 is fixed within the box 7.

In addition, multiple linear notches that facilitate bending are formed at intervals along the fold lines between the main body 102 and the rising portions 103-106, making it easier to bend the rising portions 103-106 relative to the main body 102. Note that the notches formed along the fold lines between the main body 102 and the rising portions 103-106 (i.e., the notches that facilitate bending) may be omitted.

The method of using the box 5 with the cushioning device will now be described. First, the stored item P is stored in the box body 8 of the box 7 (see FIG. 6). Note that the central area 102-1 in the main body 102 is provided in the center of the main body 102, and the circumferential cuts 110 to 170 are formed concentrically, so that the stored item P is placed in the center of the bottom surface 10.

Then, with the raised portions 103 to 106 raised relative to the main body portion 102, the cushioning device 100 is placed above the stored item P (see FIG. 7). Note that the flap portions 60 and 70 are located outside the raised portions 104 and 105, and in the example of FIG. 7, the flap portion 60 is in contact with the outer surface of the raised portion 104, and the flap portion 70 is in contact with the outer surface of the raised portion 105.

Then, the cushioning device 100 is pushed downward so that the raised portion 103 is aligned with the inside surface of the inner front portion 18, the raised portion 104 is aligned with the inside surface of the right side portion 30, the raised portion 105 is aligned with the inside surface of the left side portion 40, and the raised portion 106 is aligned with the inside surface of the back portion 50. Then, as shown in FIG. 8, the main body portion 102 deforms into a three-dimensional mesh shape according to the outer shape of the stored item P, and covers the stored item P except for its underside, and since the bottom portion 10 is in contact with the underside of the stored item P, the bottom portion 10 and the main body portion 102 encase the stored item P. Furthermore, because the raised portions 103 to 106 are aligned with the inner surface of the box body 8 (the inner surface of the side wall consisting of the front portion 12, right side portion 30, left side portion 40, and back portion 50), the cushioning device 100 is stably positioned within the box body 8, and the stored item covered by the main body portion 102 can be prevented from moving within the box body 7.

The main body 102 has multiple concentric circumferential notches 110-170, so that the main body 102 deforms according to the shape and size of the stored object. Basically, if the stored object is large, a wide area of the main body 102 deforms, especially the outer area, whereas if the stored object is small, the area of the main body 102 that deforms is small.

Then, the flap portions 60, 70 are closed (Fig. 9), and the lid portion 80 is closed (Figs. 10, 11). To close the lid portion 80, the insertion piece 96 is inserted into the insertion receiving portion 20 so that the tip portion 96b is positioned between the inner front portion 18 and the outer front portion 14. When the insertion piece 96 is inserted into the insertion receiving portion 20, the insertion piece 96 cannot be pulled out of the insertion receiving portion 20 because notches 24 are provided on both sides of the insertion receiving portion 20.

When the lid 80 is closed, the flap 60 contacts the edge J4b at the tip of the rising portion 104 to restrict the rising portion 104 from moving upward, and the flap 70 contacts the edge J5b at the tip of the rising portion 105 to restrict the rising portion 105 from moving upward, preventing the cushioning device 100 from moving up and down and fixing the cushioning device 100 within the box 7, and the stored item P is covered by the bottom surface 10 and the main body 102, preventing the stored item P from moving within the box 7 and holding the stored item P. In addition, the stored item P is stored in the box 7 and is covered by the main body 102 formed in a three-dimensional mesh shape (see FIG. 12), so that the cushioning effect of the main body 102 can be obtained and the box 7 can be protected from impacts from the outside.

To open the lid 80 and remove the stored item P, the end of the belt-like portion 94 is grasped and pulled to break the cut lines 92K, 94K and remove the belt-like portion 94, thereby opening the lid 80 from the box body 8, and the stored item P can be removed by removing the cushioning device 100 from the box body 8.

According to the box 5 with cushioning device of this embodiment, the cushioning device 100 is placed above the stored object and simply pushed downward, causing the main body 102 to deform and hold the stored object, so the stored object can be held without any hassle, and in particular, since multiple circumferential cuts 110-170 are provided concentrically, it can accommodate stored objects of different shapes and sizes. Also, since only one cushioning device 100 is used to hold the stored object, it can be held with fewer parts. Also, since the cushioning device 100 is made of paper, there is no need to use plastic products and no plastic waste is produced, which helps to eliminate plastic.

Next, another example of the shock absorber will be described. The shock absorber 200 (the shock absorber of Example 2) has a configuration that is substantially the same as that of the shock absorber 100, but the shape of the notches provided at the corners of each circumferential notch is different. That is, in the notches 111, 113, 115, 117, 131, 133, 135, 137, 151, 153, 155, 157, 171, 173, 175, 177 provided at the corners of the circumferential notches 110, 130, 150, 170 in the shock absorber 100, the corner notches B are formed in an inclined straight line, but in the shock absorber 200, the corner notches B' are formed in an arc shape (or may be substantially arc shape).

That is, the cushioning device 200 is configured as shown in Figures 13 to 15, and has a main body 202 and raised portions 203, 204, 205, and 206 that are connected to each side of the main body 202 via folding lines. The cushioning device 200 is formed entirely from a single sheet-like blank (specifically, a blank made of cardboard (e.g., thin cardboard), but may also be a blank made of other paper such as a cardboard blank). Note that Figures 13 to 15 are the same figure, and are explained separately in multiple figures in order to indicate the reference numbers.

Here, the main body 202 has a square (specifically, rectangular) outer shape, similar to the main body 102.

The main body portion 202 also has multiple circumferential discontinuous cuts (hereinafter simply referred to as "circumferential cuts") 210-270 formed therein.

In other words, the circumferential notches 210 to 270 are formed concentrically, with the diameters decreasing from the outside to the inside in the order of circumferential notches 210, 220, 230, 240, 250, 260, and 270.

The circumferential cut 210 includes a cut 211 formed on the corner (front right corner) of the front and right side of the main body 202, a cut 213 formed on the corner (rear right corner) of the back and right side of the main body 202, a cut 215 formed on the corner (rear left corner) of the back and left side of the main body 202, and a cut 217 formed on the corner (front left corner) of the front and left side of the main body 202.

Here, the cuts 211, 213, 215, and 217 have a linear cut A formed in the left-right direction, a cut C formed in the front-rear direction, and a cut B' formed between cuts A and C and shaped like an arc (or may be shaped like an approximate arc). The arc in cut B' bulges outward from the main body 202 (i.e., bulges toward the intersection of the imaginary extension of cut A and the imaginary extension of cut C), and the tangent to the end of cut B' on the cut A side overlaps with cut A, and cut B' is continuous with cut A, and the tangent to the end of cut B' on the cut C side overlaps with cut C, and cut B' is continuous with cut C.

The notch C of the notch 211 and the notch C of the notch 213 are on the same straight line, and a seam 212 without a notch is formed between the notch C of the notch 211 and the notch C of the notch 213. In other words, the seam 212 is formed along a straight imaginary line between the two notches C.

Similarly, the cut A of the cut 213 and the cut A of the cut 215 are on the same straight line, and a seam 214 without a cut is formed between the cut A of the cut 213 and the cut A of the cut 215. In other words, the seam 214 is formed along a straight imaginary line between the two cuts A.

Similarly, the cut C of cut 215 and the cut C of cut 217 are on the same straight line, and a seam 216 without a cut is formed between the cut C of cut 215 and the cut C of cut 217. In other words, the seam 216 is formed along a straight imaginary line between the two cuts C.

Similarly, the cut A of the cut 217 and the cut A of the cut 211 are on the same straight line, and a seam 218 where no cut is formed is formed between the cut A of the cut 217 and the cut A of the cut 211. In other words, the seam 218 is formed along a straight imaginary line between the two cuts A.

As described above, the notches 211, 213, 215, and 217 are formed on a circumferential virtual line, and the notches and seams are formed alternately along the circumferential virtual line, so that the multiple notches 211, 213, 215, and 217 are formed circumferentially via the seams 212, 214, 216, and 218.

The circumferential cut 220 has the same configuration as the circumferential cut 120, and has a linear cut 221 formed on the right side, a linear cut 223 formed on the back side, a linear cut 225 formed on the left side, and a linear cut 227 formed on the front side.

In addition, a seam 222 where no cut is formed is formed between the cuts 221 and 223. In other words, the seam 222 is formed along a virtual line including an arc shape (which may be approximately arc shape) between the end of the cut 221 (the end on the back side) and the end of the cut 223 (the end on the right side) (i.e., a virtual line consisting of an arc-shaped (which may be approximately arc-shaped) virtual line, a straight virtual line connected from one end of the arc-shaped virtual line, and a straight virtual line connected from the other end of the arc-shaped virtual line).

Similarly, a seam 224 without a cut is formed between the cuts 223 and 225. That is, the seam 224 is formed along a virtual line including an arc shape (which may be approximately arc shape) between the end of the cut 223 (the end on the left side face side) and the end of the cut 225 (the end on the back side) (i.e., a virtual line consisting of an arc-shaped (which may be approximately arc-shaped) virtual line, a straight virtual line connected from one end of the arc-shaped virtual line, and a straight virtual line connected from the other end of the arc-shaped virtual line).

Similarly, a seam 226 without a cut is formed between the cuts 225 and 227. That is, the seam 226 is formed along a virtual line including an arc shape (which may be approximately arc shape) between the end of the cut 225 (the end on the front side) and the end of the cut 227 (the end on the left side) (i.e., a virtual line consisting of an arc-shaped (which may be approximately arc-shaped) virtual line, a straight virtual line connected from one end of the arc-shaped virtual line, and a straight virtual line connected from the other end of the arc-shaped virtual line).

Similarly, a seam 228 where no cut is formed is formed between the cut 227 and the cut 221. In other words, the seam 228 is formed along a virtual line including an arc shape (which may be approximately arc shape) between the end of the cut 227 (the end on the right side) and the end of the cut 221 (the end on the front side) (i.e., a virtual line consisting of an arc-shaped (which may be approximately arc-shaped) virtual line, a straight virtual line connected from one end of the arc-shaped virtual line, and a straight virtual line connected from the other end of the arc-shaped virtual line).

As described above, the seams 222, 224, 226, 228 are formed along imaginary lines that are inclined with respect to the left-right and front-rear directions, and the cuts 221, 223, 225, 227 are formed on a circumferential imaginary line, and the cuts and seams are formed alternately along the circumferential imaginary line, so that the multiple cuts 221, 223, 225, 227 are formed circumferentially via the seams 222, 224, 226, 228.

The circumferential cut 230 has a substantially similar configuration to the circumferential cut 210, except that the size of the circumferential imaginary line is different (i.e., the circumferential cut 230 is substantially similar in shape to the circumferential cut 210), and is formed in the following order along the circumferential imaginary line: cut 231, seam 232, cut 233, seam 234, cut 235, seam 236, cut 237, seam 238. In other words, the cuts 231, 233, 235, and 237 are formed on the circumferential imaginary line, and the cuts and seams are alternately formed along the circumferential imaginary line, and the multiple cuts 231, 233, 235, and 237 are formed circumferentially via the seams 232, 234, 236, and 238.

All of the cuts 231, 233, 235, and 237 have cut A, cut B', and cut C, where cut A is a linear cut formed in the left-right direction, cut C is a linear cut formed in the front-rear direction, and cut B' is provided between cuts A and C and is formed in an arc shape (or may be approximately arc shape).

In addition, the circumferential cut 240 has a substantially similar configuration to the circumferential cut 220, except that the size of the circumferential imaginary line is different (i.e., the circumferential cut 240 has a substantially similar shape to the circumferential cut 220). The circumferential cut 240 has a linear cut 241 formed on the right side, a linear cut 243 formed on the back side, a linear cut 245 formed on the left side, and a linear cut 247 formed on the front side. The seam 242 between the cut 241 and the cut 243, the seam 244 between the cut 243 and the cut 245, the seam 246 between the cut 245 and the cut 247, and the seam 247 between the cut 247 and the cut 241 are also formed. and the seam 248 between the cut 241 is formed along a virtual line including an arc shape (which may be approximately arc shape) (i.e., a virtual line consisting of an arc-shaped (which may be approximately arc shape) virtual line, a straight virtual line connected from one end of the arc-shaped virtual line, and a straight virtual line connected from the other end of the arc-shaped virtual line), and the cuts 241, 243, 245, 247 are formed on a circumferential virtual line, and the cuts and seams are formed alternately along the circumferential virtual line, and the multiple cuts 241, 243, 245, 247 are formed circumferentially via the seams 242, 244, 246, 248.

The circumferential cut 250 has a substantially similar configuration to the circumferential cuts 210 and 230, except that the size of the circumferential imaginary line is different (i.e., the circumferential cut 250 is substantially similar in shape to the circumferential cuts 210 and 230), and is formed in the following order along the circumferential imaginary line: cut 251, seam 252, cut 253, seam 254, cut 255, seam 256, cut 257, seam 258. In other words, the cuts 251, 253, 255, and 257 are formed on the circumferential imaginary line, and the cuts and seams are alternately formed along the circumferential imaginary line, and the multiple cuts 251, 253, 255, and 257 are formed circumferentially via the seams 252, 254, 256, and 258.

All of the cuts 251, 253, 255, and 257 have cut A, cut B', and cut C, where cut A is a linear cut formed in the left-right direction, cut C is a linear cut formed in the front-rear direction, and cut B' is provided between cuts A and C and is formed in an arc shape (or may be approximately arc shape).

In addition, the circumferential cut 260 has a substantially similar configuration to the circumferential cuts 220 and 240, except that the size of the circumferential imaginary line is different (i.e., the circumferential cut 260 is substantially similar in shape to the circumferential cuts 220 and 240). The circumferential cut 260 has a linear cut 261 formed on the right side, a linear cut 263 formed on the back side, a linear cut 265 formed on the left side, and a linear cut 267 formed on the front side. The seam 262 between the cut 261 and the cut 263, the seam 264 between the cut 263 and the cut 265, the seam 266 between the cut 265 and the cut 267, and the seam 268 between the cut 265 and the cut 267 are also formed. The seam 268 between the notch 267 and the cut 261 is formed along a virtual line including an arc shape (or may be approximately arc shape) (i.e., a virtual line consisting of an arc-shaped (or approximately arc-shaped) virtual line, a straight virtual line connected from one end of the arc-shaped virtual line, and a straight virtual line connected from the other end of the arc-shaped virtual line), and the cuts 261, 263, 265, 267 are formed on a circumferential virtual line, and the cuts and seams are formed alternately along the circumferential virtual line, and the multiple cuts 261, 263, 265, 267 are formed circumferentially via the seams 262, 264, 266, 268.

The circumferential cut 270 has a substantially similar configuration to the circumferential cuts 210, 230, and 250, except that the size of the circumferential imaginary line is different (i.e., the circumferential cut 270 is substantially similar in shape to the circumferential cuts 210, 230, and 250), and is formed along the circumferential imaginary line in the following order: cut 271, seam 272, cut 273, seam 274, cut 275, seam 276, cut 277, and seam 278. In other words, the cuts 271, 273, 275, and 277 are formed on the circumferential imaginary line, and the cuts and seams are alternately formed along the circumferential imaginary line, and the multiple cuts 271, 273, 275, and 277 are formed circumferentially via the seams 272, 274, 276, and 278.

All of the cuts 271, 273, 275, and 277 have cut A, cut B', and cut C, where cut A is a linear cut formed in the left-right direction, cut C is a linear cut formed in the front-rear direction, and cut B' is provided between cuts A and C and is formed in an arc shape (or may be approximately arc shape). The central region 202-1, which is the region surrounded by the peripheral imaginary line in the circumferential cut 270, is provided in the center of the main body 202.

In addition, among the circumferential cuts 210 to 270, the circumferential cuts 210, 230, 250, and 270 are first-type circumferential cuts, and the circumferential cuts 220, 240, and 260 are second-type circumferential cuts. In other words, the multiple circumferential cuts 210 to 270 are composed of multiple first-type circumferential cuts and multiple second-type circumferential cuts (i.e., the multiple circumferential cuts 210 to 270 include multiple first-type circumferential cuts and multiple second-type circumferential cuts), and the first-type circumferential cuts and the second-type circumferential cuts are alternately provided from the outside to the inside. In addition, each of the circumferential cuts 210, 230, 250, and 270 (cuts 211, 213, 215, 217, 231, 233, 235, 237, 251, 253, 255, 257, 271, 273, 275, and 277) abuts the corner side cuts provided on the four corner sides of the main body 202.

In addition, in the circumferential cuts 220, 240, and 260, the cuts 223, 227, 243, 247, 263, and 267 correspond to linear fourth cuts parallel to the side portion (first side portion) Ha, and the cuts 221, 225, 241, 245, 261, and 265 correspond to linear fifth cuts parallel to the side portion (second side portion) Hb, and a pair of fourth cuts and a pair of fifth cuts are provided in each of the circumferential cuts 220, 240, and 260.

Furthermore, in the above-mentioned circumferential cuts 210, 230, 250, and 270, cut A corresponds to the first cut, cut B' corresponds to the third cut, and cut C corresponds to the second cut.

In addition, each of the circumferential cuts 210, 230, 250, and 270 is an angle side cut provided on the four corner sides of the main body portion 202.

The circumferential cuts 210 to 270 are formed as described above, and in the circumferential cuts 210 to 270, multiple cuts and seams are formed along a circumferential imaginary line, and the imaginary lines in the circumferential cuts 210 to 270 are formed concentrically, but the imaginary lines are formed so that they gradually become smaller from the circumferential cut 210 to the circumferential cut 270.

In addition, in the above circumferential cuts 210 to 270, the directions of cuts A are parallel to each other, and the directions of cuts B are parallel to each other.

As described above, in each of the multiple circumferential cuts 210 to 270, the multiple cuts are formed along a circumferential imaginary line via a seam. In addition, the diameter of the peripheral imaginary line differs in each circumferential cut, and the imaginary lines in the multiple circumferential cuts are formed concentrically.

In addition, in two circumferential cuts adjacent to each other through a circumferential cut, a target circumferential discontinuous cut (hereinafter referred to as a "target circumferential cut"), a target cut is provided between the seams of the target circumferential cut, and the target cut is provided between a cut that continues from the seam of one of the two circumferential cuts and a cut that continues from the seam of the other circumferential cut, so that a detour is provided between the two seams to bypass the straight path between the two seams.

For example, when the circumferential cut 220 is the target circumferential cut, in the two circumferential cuts 210, 230 adjacent to each other through the circumferential cut 220, the cut (target cut) 227 of the circumferential cut 220 is provided between the seam 218 and the seam 238, and the cut 227 is provided at a position between the cut A (cut A of the cut 217 (cut A1)) continuing from the seam 218 of one of the circumferential cuts 210 and the cut A (cut A of the cut 237 (cut A2))) continuing from the seam 238 of the other circumferential cut 230 (i.e., three cuts are formed side by side), so that a detour S2 is provided between the seams 218 and 238, which detours around the straight path S1 between the seams 218 and 238.

As a result, when the sheet-like cushioning device 200 is placed over the stored item, the region R1 between the cut 227 and the cut A1 is inclined relative to the region R2 along the seam 218, and the region R3 between the cut 227 and the cut A2 is inclined relative to the region R4 along the seam 238. In this way, while the region along the seam remains horizontal, the region between the two cuts is inclined, so that when the cushioning device 200 is placed over the stored item, it forms a three-dimensional mesh shape.

In addition, in the cushioning device 200, the length L1 between the side Hb and the side Hc of the main body 202 is formed to be approximately the same as the length L11 between the side 10b on the right side and the side 10c on the left side of the bottom surface 10 of the box main body 8 (strictly speaking, the length L1 is slightly shorter than the length L11), and the length L2 between the side Ha and the side Hd of the main body 202 is formed to be approximately the same as the length L12 between the side 10a on the front side and the side 10d on the back side of the bottom surface 10 of the box main body 8 (strictly speaking, the length L2 is slightly shorter than the length L12). ) is formed, so that when the cushioning device 200 is stored in the box body 8, the outer surface of the raised portion 203 contacts the inner front portion 18 while lining up with the inner surface of the inner front portion 18, the outer surface of the raised portion 204 contacts the right side portion 30 while lining up with the inner surface of the right side portion 30, the outer surface of the raised portion 205 contacts the left side portion 40 while lining up with the inner surface of the left side portion 40, and the outer surface of the raised portion 206 contacts the rear portion 50 while lining up with the inner surface of the rear portion 50.

Note that the sides Ha, Hb, Hc, and Hd of the main body 202 are along the folded lines between the raised portions 203 to 206 of the main body 202.

The configuration of the raised portion 203 is the same as that of the raised portion 103, the configuration of the raised portion 204 is the same as that of the raised portion 104, the configuration of the raised portion 205 is the same as that of the raised portion 105, and the configuration of the raised portion 206 is the same as that of the raised portion 106, and the lengths La to La are formed to be the same, and the lengths La, Lb, Lc, and Ld are formed to be the same (or may be approximately the same) as the lengths L30 and L40 of the box body 7. As a result, in the cushioning device 200, the raised portions 203 to 206 are raised relative to the main body 202, and the cushioning device 200 is stored in the box body 7 with the lid portion 80 closed, so that the flap portions 60 and 70 come into contact with the upper ends of the raised portions 204 and 205, and the cushioning device 200 is fixed in the box body 7.

In addition, multiple linear notches that facilitate bending are formed at intervals along the fold lines between the main body portion 202 and the rising portions 203-206, making it easier to bend the rising portions 203-206 relative to the main body portion 202. Note that the notches formed along the fold lines between the main body portion 202 and the rising portions 203-206 (i.e., the notches that facilitate bending) may be omitted.

The method of using the cushioning device 200 is the same as that of the cushioning device 100, so a detailed explanation will be omitted. In the case of the cushioning device 200, when the cushioning device 200 is placed above the stored object and then pushed downward, the main body 202 deforms into a three-dimensional mesh shape that conforms to the outer shape of the stored object, covering the object except for its underside, and since the bottom surface 10 is in contact with the underside of the stored object, the bottom surface 10 and the main body 202 cover the object. Note that the main body 202 has multiple concentric circumferential cuts 210-270, so the main body 202 deforms according to the shape and size of the stored object.

When the lid 80 is closed, the flap 60 contacts the tip of the rising portion 204, restricting the rising portion 204 from moving upward, and the flap 70 contacts the tip of the rising portion 205, restricting the rising portion 205 from moving upward, preventing the cushioning device 200 from moving up and down, fixing the cushioning device 200 within the box 7, and the stored item is covered by the bottom portion 10 and the main body 202, preventing the stored item from moving within the box 7 and holding the stored item. In addition, the stored item is stored in the box 7 and covered by the main body 202 formed in a three-dimensional mesh shape, so that the cushioning effect of the main body 202 can be obtained and the box 7 can be protected from impacts from the outside.

Next, cushioning device 300 (cushioning device of Example 3), which is another example of a cushioning device, has a configuration that is substantially the same as cushioning device 100, but differs in that the left-right cut (cut A) and the front-rear cut (cut B) in the outermost circumferential cut are formed along the boundary line between main body portion 302 and raised portions 303-306.

That is, the cushioning device 300 is configured as shown in Figures 16 to 19, and has a main body 302 and raised portions 303, 304, 305, and 306 that are connected to each side of the main body 302 via folding lines. The cushioning device 300 is formed entirely from a single sheet-like blank (specifically, a blank made of cardboard (e.g., thin cardboard), but may also be a blank made of other paper such as a cardboard blank). Note that Figures 16 to 19 are the same figure, and are explained separately in multiple figures in order to indicate the reference numbers.

Here, the main body 302 has a square (specifically, rectangular) outer shape, similar to the main body 102. The boundary between the main body 302 and the raised portions 303 to 306 is formed linearly by the bend line and the cuts A and C.

The cushioning device 300 is formed with a number of discontinuous circumferential cuts (hereinafter simply referred to as "circumferential cuts") 310-390, with the circumferential cuts 320-390 being provided in the main body portion 302, with a portion of the circumferential cut 310 being formed at the boundary between the main body portion 302 and the raised portions 303-306 (i.e., on an extension of the broken line between the main body portion 302 and the raised portions 303-306), and the other portion of the circumferential cut 310 being formed in the main body portion 302.

In other words, the circumferential cuts 310 to 390 are formed concentrically, with the diameters decreasing from the outside to the inside in the order of circumferential cuts 310, 320, 330, 340, 350, 360, 370, 380, and 390.

The circumferential cut 310 includes a cut 311 formed on the corner (front right corner) of the front and right side of the main body 302, a cut 313 formed on the corner (rear right corner) of the back and right side of the main body 302, a cut 315 formed on the corner (rear left corner) of the back and left side of the main body 302, and a cut 317 formed on the corner (front left corner) of the front and left side of the main body 302.

Here, cuts 311, 313, 315, and 317 have a linear cut A formed in the left-right direction, a cut C formed in the front-rear direction, and a linear cut B provided between cuts A and C and inclined with respect to cuts A and C (specifically, inclined at 45 degrees).

Then, the notch A in the notch 311 is formed along the boundary between the main body portion 302 and the rising portion 303, and the notch C in the notch 311 is formed along the boundary between the main body portion 302 and the rising portion 304.

In addition, cut A in cut 313 is formed along the boundary between main body portion 302 and rising portion 306, and cut C in cut 313 is formed along the boundary between main body portion 302 and rising portion 304.

In addition, cut A in cut 315 is formed along the boundary between main body portion 302 and rising portion 306, and cut C in cut 315 is formed along the boundary between main body portion 302 and rising portion 305.

In addition, cut A in cut 317 is formed along the boundary between main body portion 302 and rising portion 303, and cut C in cut 317 is formed along the boundary between main body portion 302 and rising portion 305.

The notch C of the notch 311 and the notch C of the notch 313 are on the same straight line, and a seam 312 is formed between the notch C of the notch 311 and the notch C of the notch 313. As described later, this seam 312 has multiple notches for folding at intervals, so strictly speaking, it is not a continuous seam, but rather multiple seams are provided between the notch C of the notch 311 and the notch C of the notch 313. However, since the main body does not deform through the notches for folding, the seam will be described as being between the notch C of the notch 311 and the notch C of the notch 313. This seam 312 coincides with the fold line M2 between the main body 302 and the rising portion 304. The notch C of the notch 311 and the notch C of the notch 313 are formed on an extension of the fold line M2.

Similarly, notch A of notch 313 and notch A of notch 315 are on the same straight line, and a seam 314 without any notches is formed between notch A of notch 313 and notch A of notch 315. As described below, this seam 314 has multiple notches for folding spaced apart, but will be described as a seam, as in the case of seam 312. This seam 314 coincides with the fold line M4 between the main body portion 302 and the rising portion 306. Notch A of notch 313 and notch A of notch 315 are formed on an extension of the fold line M4.

Similarly, the notch C of the notch 315 and the notch C of the notch 317 are on the same straight line, and a seam 316 without any notches is formed between the notch C of the notch 315 and the notch C of the notch 317. As described below, this seam 316 has multiple notches for folding spaced apart, but will be described as a seam, as in the case of the seam 312. This seam 316 coincides with the fold line M3 between the main body portion 302 and the rising portion 305. The notch C of the notch 315 and the notch C of the notch 317 are formed on an extension of the fold line M3.

Similarly, notch A of notch 317 and notch A of notch 311 are on the same straight line, and a seam 318 without any notches is formed between notch A of notch 317 and notch A of notch 311. As described below, this seam 318 has multiple notches for folding spaced apart, but will be described as a seam, as in the case of seam 312. This seam 318 coincides with the fold line M1 between the main body portion 302 and the rising portion 303. Notch A of notch 317 and notch A of notch 311 are formed on an extension of the fold line M1.

As described above, the notches 311, 313, 315, and 317 are formed on a circumferential imaginary line (although part of the imaginary line is on the boundary between the main body portion 302 and the raised portions 303 to 306), and the notches and seams are formed alternately along the circumferential imaginary line, so that the multiple notches 311, 313, 315, and 317 are formed circumferentially via the seams 312, 314, 316, and 318.

Circumferential cut 310 is the outermost discontinuous cut, which is the outermost of the circumferential cuts 310 to 390 (the same applies to Example 4).

Circumferential cut 320 has the same configuration as circumferential cut 120, and has a linear cut 321 formed on the right side, a linear cut 323 formed on the back side, a linear cut 325 formed on the left side, and a linear cut 327 formed on the front side.

A seam 322 without a cut is formed between the cuts 321 and 323. In other words, the seam 322 is formed along a straight imaginary line between the end of the cut 321 (the end on the back side) and the end of the cut 323 (the end on the right side).

Similarly, a seam 324 without a cut is formed between cuts 323 and 325. In other words, seam 324 is formed along a straight imaginary line between the end of cut 323 (the end on the left side) and the end of cut 325 (the end on the back side).

Similarly, a seam 326 without a cut is formed between the cuts 325 and 327. In other words, the seam 326 is formed along a straight imaginary line between the end of the cut 325 (the end on the front side) and the end of the cut 327 (the end on the left side).

Similarly, a seam 328 without a cut is formed between the cut 327 and the cut 321. In other words, the seam 328 is formed along a straight imaginary line between the end of the cut 327 (the end on the right side) and the end of the cut 321 (the end on the front side).

As described above, the seams 322, 324, 326, and 328 are formed along imaginary lines that are inclined relative to the left-right and front-rear directions, and the cuts 321, 323, 325, and 327 are formed on a circumferential imaginary line. The cuts and seams are formed alternately along the circumferential imaginary line, and the multiple cuts 321, 323, 325, and 327 are formed circumferentially via the seams 322, 324, 326, and 328.

In addition, the circumferential cut 330 has a substantially similar configuration to the circumferential cut 310, except that the size of the circumferential imaginary line is different (i.e., the circumferential cut 330 is substantially similar in shape to the circumferential cut 310), and is formed along the circumferential imaginary line in the following order: cut 331, seam 332, cut 333, seam 334, cut 335, seam 336, cut 337, and seam 338. In other words, the cuts 331, 333, 335, and 337 are formed on the circumferential imaginary line, and the cuts and seams are alternately formed along the circumferential imaginary line, and the multiple cuts 331, 333, 335, and 337 are formed circumferentially via the seams 332, 334, 336, and 338.

In addition, the circumferential cut 340 has a substantially similar configuration to the circumferential cut 320, except that the size of the circumferential imaginary line is different (i.e., the circumferential cut 340 is substantially similar in shape to the circumferential cut 320). The circumferential cut 340 has a linear cut 341 formed on the right side, a linear cut 343 formed on the back side, a linear cut 345 formed on the left side, and a linear cut 347 formed on the front side. The joint 342 between the cuts 341 and 343 and the joint 344 between the cuts 341 and 343 are also different. The seam 344 between 43 and cut 345, the seam 346 between cut 345 and cut 347, and the seam 348 between cut 347 and cut 341 are formed along imaginary lines inclined with respect to the left-right and front-back directions, and the cuts 341, 343, 345, and 347 are formed on a circumferential imaginary line, and the cuts and seams are formed alternately along the circumferential imaginary line, with the multiple cuts 341, 343, 345, and 347 being formed circumferentially via the seams 342, 344, 346, and 348.

The circumferential cut 350 has a substantially similar configuration to the circumferential cuts 310 and 330, except that the size of the circumferential imaginary line is different (i.e., the circumferential cut 350 is substantially similar in shape to the circumferential cuts 310 and 330), and is formed in the following order along the circumferential imaginary line: cut 351, seam 352, cut 353, seam 354, cut 355, seam 356, cut 357, and seam 358. In other words, the cuts 351, 353, 355, and 357 are formed on the circumferential imaginary line, and the cuts and seams are alternately formed along the circumferential imaginary line, and the multiple cuts 351, 353, 355, and 357 are formed circumferentially via the seams 352, 354, 356, and 358.

The circumferential cut 360 has a linear cut 361 formed on the right side, a linear cut 363 formed on the back side, a linear cut 365 formed on the left side, and a linear cut 367 formed on the front side. The joint 362 between the cuts 361 and 363, The seam 364 between the cuts 363 and 365, the seam 366 between the cuts 365 and 367, and the seam 368 between the cuts 367 and 361 are formed along imaginary lines that are inclined with respect to the left-right and front-back directions, and the cuts 361, 363, 365, and 367 are formed on a circumferential imaginary line, and the cuts and seams are formed alternately along the circumferential imaginary line, with the multiple cuts 361, 363, 365, and 367 being formed circumferentially via the seams 362, 364, 366, and 368.

The circumferential cut 370 has a substantially similar configuration to the circumferential cuts 310, 330, and 350, except that the size of the circumferential imaginary line is different (i.e., the circumferential cut 370 is substantially similar in shape to the circumferential cuts 310, 330, and 350), and is formed in the following order along the circumferential imaginary line: cut 371, seam 372, cut 373, seam 374, cut 375, seam 376, cut 377, and seam 378. In other words, the cuts 371, 373, 375, and 377 are formed on the circumferential imaginary line, and the cuts and seams are alternately formed along the circumferential imaginary line, and the multiple cuts 371, 373, 375, and 377 are formed circumferentially via the seams 372, 374, 376, and 378.

The circumferential cut 390 has a substantially similar configuration to the circumferential cuts 310, 330, 350, and 370, except that the size of the circumferential imaginary line is different (i.e., the circumferential cut 390 is substantially similar to the circumferential cuts 310, 330, 350, and 370), and is formed along the circumferential imaginary line in the following order: cut 391, seam 392, cut 393, seam 394, cut 395, seam 396, cut 397, and seam 398.

Central region 302-1, which is the region surrounded by the peripheral imaginary line in circumferential cut 390, is provided in the center of main body 302.

In addition, among the circumferential cuts 310 to 390, the circumferential cuts 310, 330, 350, 370, and 390 are first-type circumferential cuts, and the circumferential cuts 320, 340, 360, and 380 are second-type circumferential cuts. In other words, the multiple circumferential cuts 310 to 370 are composed of multiple first-type circumferential cuts and multiple second-type circumferential cuts (i.e., the multiple circumferential cuts 310 to 390 are provided with multiple first-type circumferential cuts and multiple second-type circumferential cuts), and the first-type circumferential cuts and the second-type circumferential cuts are provided alternately from the outside to the inside. In addition, each of the circumferential cuts 310, 330, 350, 370, and 390 (cuts 311, 313, 315, 317, 331, 333, 335, 337, 351, 353, 355, 357, 371, 373, 375, 377, 391, 393, 395, and 397) abuts the corner side cuts provided on the four corner sides of the main body 302.

Furthermore, in the above-mentioned circumferential cuts 310, 330, 350, 370, and 390, cut A corresponds to the first cut, cut B corresponds to the third cut, and cut C corresponds to the second cut.

In addition, each of the circumferential cuts 310, 330, 350, 370, and 390 is an angle side cut provided on the four corner sides of the main body portion 302.

The circumferential cuts 310 to 390 are formed as described above, and in the circumferential cuts 310 to 390, multiple cuts and seams are formed along a circumferential imaginary line, and the imaginary lines in the circumferential cuts 310 to 390 are formed concentrically, but the imaginary lines are formed so that they gradually become smaller from the circumferential cut 310 to the circumferential cut 390.

In the above circumferential cuts 310 to 390, the directions of cuts A are parallel to each other, and the directions of cuts B are parallel to each other. Furthermore, the directions of cuts B in cuts 311, 331, 351, 371, 391, 315, 335, 355, 375, and 395 are parallel to each other, and the directions of cuts B in cuts 313, 333, 353, 373, 393, 317, 337, 357, 377, and 397 are parallel to each other.

As described above, in each of the multiple circumferential cuts 310-390, the multiple cuts are formed along a circumferential imaginary line via a seam. The diameter of the circumferential imaginary line is different for each circumferential cut, and the imaginary lines in the multiple circumferential cuts are formed concentrically. Note that the circumferential cuts 310-390 are provided in the main body 302, but in the cushioning device 300, a part of the circumferential cut 310 (i.e., cut A and cut C) is formed at the boundary position between the main body 302 and the rising parts 303-306, so strictly speaking, the multiple circumferential cuts 310-390 can be said to be formed in the main body 302, including the boundary with the rising parts 303-306.

In addition, in two circumferential cuts adjacent to each other through a circumferential cut, a target circumferential discontinuous cut (hereinafter referred to as a "target circumferential cut"), a target cut is provided between the seams of the target circumferential cut, and the target cut is provided between a cut that continues from the seam of one of the two circumferential cuts and a cut that continues from the seam of the other circumferential cut, so that a detour is provided between the two seams to bypass the straight path between the two seams.

For example, when the circumferential cut 320 is the target circumferential cut, in the two circumferential cuts 310, 330 adjacent to each other through the circumferential cut 320, the cut (target cut) 327 of the circumferential cut 320 is provided between the seam 318 and the seam 338, and the cut 327 is provided at a position between the cut A (cut A of the cut 317 (cut A1)) continuing from the seam 318 of one of the circumferential cuts 310 and the cut A (cut A of the cut 337 (cut A2))) continuing from the seam 338 of the other circumferential cut 330 (i.e., three cuts are formed side by side), so that a detour S2 is provided between the seams 318 and 338, which detours around the straight path S1 between the seams 318 and 338.

As a result, when the sheet-like cushioning device 300 is placed over the stored item, the region R1 between the cut 327 and the cut A1 is inclined relative to the region R2 along the seam 318, and the region R3 between the cut 327 and the cut A2 is inclined relative to the region R4 along the seam 338. In this way, while the region along the seam remains horizontal, the region between the two cuts is inclined, so that when the cushioning device 300 is placed over the stored item, it forms a three-dimensional mesh shape.

In addition, in the cushioning device 300, the length L1 between the side Hb and the side Hc of the main body 302 is formed to be approximately the same as the length L11 between the side 10b on the right side and the side 10c on the left side of the bottom surface 10 of the box main body 8 (strictly speaking, the length L1 is slightly shorter than the length L11), and the length L2 between the side Ha and the side Hd of the main body 302 is formed to be approximately the same as the length L12 between the side 10a on the front side and the side 10d on the back side of the bottom surface 10 of the box main body 8 (strictly speaking, the length L2 is slightly shorter than the length L12). ) is formed, so that when the cushioning device 300 is stored in the box body 8, the outer surface of the raised portion 303 contacts the inner front portion 18 while lining up with the inner surface of the inner front portion 18, the outer surface of the raised portion 304 contacts the right side portion 30 while lining up with the inner surface of the right side portion 30, the outer surface of the raised portion 305 contacts the left side portion 40 while lining up with the inner surface of the left side portion 40, and the outer surface of the raised portion 306 contacts the rear portion 50 while lining up with the inner surface of the rear portion 50.

Note that the sides Ha, Hb, Hc, and Hd of the main body 302 are along the bend lines between the raised portions 303 to 306 of the main body 302 and their extension lines.

The configuration of the raised portion 303 is the same as that of the raised portion 103, the configuration of the raised portion 304 is the same as that of the raised portion 104, the configuration of the raised portion 305 is the same as that of the raised portion 105, and the configuration of the raised portion 306 is the same as that of the raised portion 106, and the lengths La to Ld are formed to be the same, and the lengths La, Lb, Lc, and Ld are formed to be the same (or may be approximately the same) as the lengths L30 and L40 of the box body 7. As a result, in the cushioning device 300, the raised portions 303 to 306 are raised relative to the main body portion 302, and when the cushioning device 300 is stored in the box body 7 and the lid portion 80 is closed, the flap portions 60 and 70 come into contact with the upper ends of the raised portions 304 and 305, and the cushioning device 300 is fixed in the box body 7.

In addition, multiple linear notches that facilitate folding are formed at intervals along the fold lines between the main body 302 and the rising portions 303-306 (the fold line between notch 311 and notch 313 (i.e., seam 312), the fold line between notch 313 and notch 315 (i.e., seam 314), the fold line between notch 315 and notch 317 (i.e., seam 316), and the fold line between notch 317 and notch 311 (i.e., seam 318)), making it easier to fold the rising portions 303-306 relative to the main body 302. Note that the notches formed along the fold lines between the main body 302 and the rising portions 303-306 (i.e., the notches that facilitate folding) may be omitted.

The method of using the cushioning device 300 is the same as that of the cushioning devices 100 and 200. When the cushioning device 300 is placed above the object to be stored and then pushed downward, the main body 302 deforms into a three-dimensional mesh shape that conforms to the contours of the object to be stored, covering the object except for its underside, and since the underside of the object to be stored is in contact with the bottom surface 10, the object is covered by the bottom surface 10 and the main body 302. Note that the main body 302 has multiple concentric circumferential cuts 310-390, so the main body 302 deforms according to the shape and size of the object to be stored.

In addition, unlike cushioning devices 100 and 200, the left-right cut (cut A) and the front-rear cut (cut C) in the outermost circumferential cut 310 are formed along the boundary between the main body 302 and the raised sections 303 to 306, so that the main body can deform over a wide range and can be used to store objects that are larger in size laterally than cushioning devices 100 and 200.

In this shock absorber 300, when the lid 80 is closed, the flap 60 contacts the tip of the rising portion 304 to restrict the rising portion 304 from moving upward, and the flap 70 contacts the tip of the rising portion 305 to restrict the rising portion 305 from moving upward, preventing the shock absorber 300 from moving up and down, fixing the shock absorber 300 within the box 7, and the stored object is covered by the bottom portion 10 and the main body 302, preventing the stored object from moving within the box 7 and holding the stored object. In addition, the stored object is stored in the box 7 and covered by the main body 302 formed in a three-dimensional mesh shape, so that the shock absorber 300 can obtain a shock absorbing effect from the main body 202 and can protect the box 7 from impacts from the outside.

Next, another example of a shock absorber, shock absorber 300' (the shock absorber of Example 4), has a configuration substantially identical to that of shock absorber 300, but differs in the configuration of the outermost circumferential cut 310.

That is, the cushioning device 300' is configured as shown in FIG. 20, and has a main body 302 and raised portions 303, 304, 305, and 306 that are connected to each side of the main body 302 via folding lines. The cushioning device 300 is formed entirely from a single sheet-like blank (specifically, a blank made of cardboard (e.g., thin cardboard), but may also be a blank made of other paper such as a cardboard blank).

Here, the main body 302 has a square (specifically, rectangular) outer shape, similar to the main body 102, etc.

The cushioning device 300 also has a number of discontinuous circumferential cuts (hereinafter simply referred to as "circumferential cuts") 310-390 formed therein, with the circumferential cuts 320-390 being provided in the main body portion 302, and with respect to the circumferential cut 310, a portion of the circumferential cut 310 being formed at the boundary between the main body portion 302 and the raised portions 303-306, and the other portion of the circumferential cut 310 being formed in the main body portion 302.

Here, the circumferential cut 310 includes a cut 311' formed on the corner (front right corner) of the front and right side of the main body 302, a cut 313' formed on the corner (rear right corner) of the back and right side of the main body 302, a cut 315' formed on the corner (rear left corner) of the back and left side of the main body 302, and a cut 317' formed on the corner (front left corner) of the front and left side of the main body 302.

Here, the cuts 311', 313', 315', and 317' are a linear cut A formed in the left-right direction, a cut C formed in the front-rear direction, a linear cut B provided between cuts A and C and inclined (specifically, inclined at 45 degrees) with respect to cuts A and C, a linear cut (sixth cut) D formed at a right angle (may be approximately a right angle) to the direction of cut A from the end of cut A on the opposite side to the cut B side, a linear cut (seventh cut) E formed at a right angle (may be approximately a right angle) to the direction of cut A from the end of cut A on the cut B side (i.e., the contact point (i.e., the boundary position) of cut A and cut B), and a linear cut (seventh cut) E formed at a right angle (may be approximately a right angle) to the direction of cut A from the end of cut C on the opposite side to the cut B side. notch D and notch E are formed parallel to each other, and notch F and notch G are formed parallel to each other), notch D and notch E are formed from notch A to the raised portion side where notch A contacts (i.e., toward the outside of the cushioning device 300′ in the unfolded state), notch F and notch G are formed from notch C to the raised portion side where notch C contacts (i.e., toward the outside of the cushioning device 300′ in the unfolded state), and notch D, E, F, G are connected to the ends of folded lines M1, M2, M3, M4 between the main body portion 302 and the raised portion at midpoints from the inner end to the outer end of notches D, E, F, G. As a result, cut A and cuts D and E adjacent to cut A form an approximately U-shaped cut, and cut C and cuts F and G adjacent to cut C form an approximately U-shaped cut.

As described above, cuts A and C are formed shifted inward from the extensions of the bend lines M1 to M4 between the main body 302 and the raised portions 303 to 306. In other words, cuts A and C are provided inside the rectangular shape formed by the bend lines M1 to M4 and their extensions.

As a result, the fold line M1 is formed between the pair of cuts D, and between the corners of the main body 302 (both corners on the front side) and the cut E. Since the fold line M1 is formed outside the cut A when the cushioning device 300' is in the deployed state, the raised portion 303 has a pair of protrusions 303T consisting of a side portion along the cut A, a side portion along the cut D, and a side portion along the cut E.

Furthermore, the fold line M2 is formed between the pair of cuts F, and is also formed between the corners of the main body 302 (the corners on both sides of the right side surface) and the cut G. Since the fold line M2 is formed outside the cut C when the cushioning device 300' is in the deployed state, the raised portion 304 has a pair of protruding portions 304T consisting of a side portion along the cut C, a side portion along the cut F, and a side portion along the cut G.

Furthermore, the fold line M3 is formed between the pair of cuts F, and is also formed between the corners of the main body 302 (the corners on both sides of the left side surface) and the cut G. Since the fold line M3 is formed outside the cut C when the cushioning device 300' is in the deployed state, the raised portion 305 has a pair of protrusions 305T consisting of a side portion along the cut C, a side portion along the cut F, and a side portion along the cut G.

Furthermore, the fold line M4 is formed between the pair of cuts D, and is also formed between the corners of the main body 302 (both corners on the back side) and the cut E. Since the fold line M4 is formed outside the cut A when the cushioning device 300' is in the deployed state, the raised portion 306 has a pair of protrusions 306T consisting of a side portion along the cut A, a side portion along the cut D, and a side portion along the cut E.

In addition, cuts D, E, F, and G are formed to the same length, the amount of inward deviation of cuts A and C from fold lines M1 to M4 (the length between the extension of fold lines M1 to M4 and cuts A and C) is slight, and cuts A and C are formed near the rectangular shape formed by fold lines M1 to M4 and their extensions.

By forming the notches 311', 313', 315', and 317' as described above, it is easier to raise the raised portions 303-306 relative to the main body portion 302 than in the case of the cushioning device 300.

In other words, in the case of cushioning device 300, because notches A and C are on the extension of the fold line between main body portion 302 and rising portions 303-306, when rising portions 303-306 are raised up against main body portion 302, rising portions 303-306 must be bent against main body portion 302 at the positions of notches A and C. In this case, the sides of rising portions 303-306 along notches A and C and the sides of main body portion 302 along notches A and C are bent in contact with each other via the notches, which creates the problem that folding cannot be performed smoothly due to friction between the two sides. For example, when the raised portion 303 is bent relative to the main body portion 302, the side of the raised portion 303 along the notch A in the notch 311 is in contact with the side of the main body portion 302 along the notch A, and the side of the raised portion 303 along the notch A in the notch 317 is in contact with the side of the main body portion 302 along the notch A. Therefore, the bending cannot be performed smoothly due to friction between the two sides via the notch A.

On the other hand, in the case of the cushioning device 300', protrusions 303T-306T are provided, and notches A and C are formed shifted inward from the extensions of the fold lines M1-M4. Therefore, when the rising portions 303-306 are folded relative to the main body portion 302 via the fold lines M1-M4, the sides along notches A and C move away from the sides along notches A and C of the main body portion 302. This means that no friction occurs between the two sides via notches A and C, and the rising portions 303-306 can be folded smoothly.

For example, taking the rising portion 303 as an example, when attempting to bend the rising portion 303 relative to the main body portion 302, the side portion of the rising portion 303 along the cut A immediately separates from the side portion of the main body portion 302 along the cut A, so no friction occurs between the two sides via the cut A, and the rising portion 303 can be bent smoothly.

The configuration of the circumferential cuts 320-390 in the shock absorber 300' is similar to that of the circumferential cuts 320-390 in the shock absorber 300, so a detailed explanation will be omitted.

Among the circumferential cuts 310 to 390, the circumferential cuts 310, 330, 350, 370, and 390 are first-type circumferential cuts, and the circumferential cuts 320, 340, 360, and 380 are second-type circumferential cuts. In other words, the multiple circumferential cuts 310 to 370 are composed of multiple first-type circumferential cuts and multiple second-type circumferential cuts (i.e., the multiple circumferential cuts 310 to 390 have multiple first-type circumferential cuts and multiple second-type circumferential cuts), and the first-type circumferential cuts and the second-type circumferential cuts are alternately provided from the outside to the inside. Each of the circumferential cuts 310, 330, 350, 370, and 390 (cuts 311', 313', 315', 317', etc.) corresponds to a corner-side cut provided on the four corner sides of the main body 302.

Note that the circumferential cuts 310-390 are provided in the main body 302, but in the cushioning device 300', a portion of the circumferential cut 310 (i.e., cut A and cut C) is also formed at the boundary between the main body 302 and the raised portions 303-306. Strictly speaking, the multiple circumferential cuts 310-390 can be said to be formed in the main body 302, including the boundary with the raised portions 303-306.

The configuration of rising portion 303 is substantially the same as that of rising portion 303 of cushioning device 300, the configuration of rising portion 304 is substantially the same as that of rising portion 104 of cushioning device 300, the configuration of rising portion 305 is substantially the same as that of rising portion 305 of cushioning device 300, and the configuration of rising portion 306 is substantially the same as that of rising portion 306 of cushioning device 300, except that, due to the formation of a substantially U-shaped cut between main body portion 302 and rising portions 303-306, the boundary between main body portion 302 and rising portions 303-306 is not linear.

In the shock absorber 300', the lengths La to Ld are the same, and the lengths La, Lb, Lc, and Ld are the same (or may be approximately the same) as the lengths L30 and L40 in the box 7. As a result, in the shock absorber 300, when the raised portions 303 to 306 are raised relative to the main body 302 and stored in the box 7, and the lid 80 is closed, the flap portions 60 and 70 come into contact with the upper ends of the raised portions 304 and 305, and the shock absorber 300 is fixed in the box 7.

In addition, in the cushioning device 300', the lengths La to Ld are the lengths between the bend lines M1 to M4 and the edge portions J3a to J6b on the tip side of the raised portions 303 to 306.

In addition, multiple linear notches that facilitate bending are formed at intervals along the fold lines M1 to M4 between the main body portion 302 and the rising portions 303 to 306, making it easier to bend the rising portions 303 to 306 relative to the main body portion 302. Note that the notches formed along the fold lines between the main body portion 302 and the rising portions 303 to 306 (i.e., the notches that facilitate bending) may be omitted.

The method of using the cushioning device 300' is the same as that of the cushioning device 300. By pressing the cushioning device 300' downward from a state in which the cushioning device 300' is placed above the stored object, the main body 302 deforms into a three-dimensional mesh shape according to the outer shape of the stored object, covering the stored object except for its underside, and since the underside of the stored object is in contact with the bottom surface 10, the stored object is covered by the bottom surface 10 and the main body 202. Note that the main body 302 has multiple concentric circumferential cuts 310-390, so the main body 302 deforms according to the shape and size of the stored object.

In addition, in the case of the cushioning device 300, the left-right cut (cut A) and the front-rear cut (cut C) in the outermost circumferential cut 310 are formed near the extensions of the fold lines M1 to M4 between the main body 302 and the raised parts 303 to 306, similar to the cushioning device 300, so that the cushioning device 300' can be used for stored objects that are larger in size in the horizontal direction than the cushioning devices 100 and 200.

In this shock absorber 300', when the lid 80 is closed, the flap 60 contacts the tip of the rising portion 304 to restrict the rising portion 304 from moving upward, and the flap 70 contacts the tip of the rising portion 305 to restrict the rising portion 305 from moving upward, preventing the shock absorber 300' from moving up and down, fixing the shock absorber 300 within the box 7, and the stored object is covered by the bottom portion 10 and the main body 302, preventing the stored object from moving within the box 7 and holding the stored object. In addition, the stored object is stored in the box 7 and covered by the main body 302 formed in a three-dimensional mesh shape, so that the shock absorber 202 provides a cushioning effect and protects the box 7 from external shocks.

In addition, in the cushioning device 300 of Example 3 and the cushioning device 300' of Example 4, a linear cut B is provided between the cut A and the cut C, but instead of the cut B, an arc-shaped cut B' (which may be approximately arc-shaped) may be provided.

In the above description, the incision B is linear, but the incision B may be configured with approximately arc-shaped incisions on both sides of the linear incision, with an arc between the linear incisions in incision A and incision B, and an arc between the linear incisions in incision C and incision B. In other words, incision B may have a linear incision, and as a result, both ends of incision B, which is a linear incision, may be connected to the ends of incision A and incision B, or both ends of the linear incision in incision B may be connected to the ends of incision A and incision B via an approximately arc-shaped incision. By providing an incision with an arc shape in this way, a curved incision is provided between the adjacent linear incisions, and a smoothly curved shape is formed from the end of one linear incision to the end of the other linear incision.

In addition, in the above-mentioned shock absorbers 100, 200, 300, 300', the raised portions 103, 203, 303 on the front side and the raised portions 106, 206, 306 on the rear side may be omitted. Even in this case, the flap portion 60 contacts the raised portions 104, 204, 304 on the right side side, and the flap portion 70 contacts the raised portions 105, 205, 305 on the left side side, preventing the shock absorber from moving up and down, and allowing the shock absorber to be fixed inside the box body 7 and holding the stored items.
