Japanese Unexamined Patent Publication No. 2005-126127

A packaging container as described above is produced by cutting out a packaging body from a single flat plate material (for example, paper) and bending the packaging body. In the unfolded state of the packaging container, the front plate 5 arranged between the pair of side plates 4 is connected to the bottom plate 6 in the longitudinal direction. In this configuration, the total length of the packaged container in the unfolded state has a total length of the length of the front plate 5 in the longitudinal direction and the length of the bottom plate 6 in the longitudinal direction. As a result, if the packaging container is to be stored in an unfolded state, a long storage space must be prepared.

This specification discloses a technique for suppressing the total length of the packaged container in an unfolded state.

The packaging container formed by bending one flat plate disclosed in the present specification is a pair of facing plates facing each other at intervals, and each facing plate is of three sides and the three sides. A pair of facing plates having three corners connecting the ends of the two sides, and a pair of the first sides facing each other, which are the longest first sides of the three sides of the pair of facing plates. A pair of second sides facing each other among the first intermediate plate arranged between the pair and rotatably connected to each of the pair of first sides and the three sides of the pair of facing plates. The second intermediate plate, which is arranged between the two sides and is rotatably connected to the second side of one of the pair of second sides, and the three sides of the pair of facing plates, which are connected to each other. The second intermediate plate is provided between a pair of third sides facing each other and is rotatably connected to the third side of one of the pair of third sides. The intermediate plate extends between the pair of second sides over a length of more than half the distance between the pair of second sides, and the third intermediate plate extends between the pair of third sides. In a state where the packaging container extends between the pair of third sides over a length of more than half of the distance between the sides and the packaging container is developed on the one flat plate, the first intermediate The plate, the second intermediate plate, and the third intermediate plate may be separated from each other.

According to the above configuration, since the first intermediate plate, the second intermediate plate, and the third intermediate plate are arranged around the facing plates in the unfolded state of the packaging container, the first intermediate plate and the second intermediate plate are arranged. It is not necessary to adopt a configuration in which any two intermediate plates of the plate and the third intermediate plate are arranged side by side in the longitudinal direction thereof. As a result, the total length of the packaged container in the unfolded state can be suppressed.

The angle formed by the second side and the third side may be a right angle.

The packaging container is further arranged between the pair of second sides, and is rotatably connected to the other second side of the pair of second sides. A fifth intermediate plate arranged between the pair of third sides and rotatably connected to the other fifth side of the pair of third sides is provided, and the second intermediate plate is provided. The plate may overlap the fourth intermediate plate over the entire surface, and the third intermediate plate may overlap the fifth intermediate plate over the entire surface. In this configuration, the second intermediate plate and the fourth intermediate plate overlap, and the third intermediate plate and the fifth intermediate plate overlap to reinforce the packaging container. Thereby, the strength of the packaging container can be improved.

The packaging container may further include a tag that is connected to one side of the first intermediate plate and extends to the outside of the packaging container. In this configuration, for example, information about the stored items in the packaging container can be described in the tag.

The single flat plate is formed by overlapping a plurality of layers of sheets, and the plurality of layers of sheets may include a flat sheet and a corrugated sheet extending in a specific direction.

(First Example)
FIG. 2 shows a perspective view of the triangular prism-shaped packaging container 100. The packaging container 100 is used for storing various products (for example, triangular sandwiches) and displaying them in a store. FIG. 3 shows a blank 100a in which the packaging container 100 is unfolded. The packaging container 100 is formed by bending a blank 100a, which is a single flat plate. The packaging container 100 is made of durable paper such as corrugated cardboard. The corrugated cardboard includes, for example, a flat front surface sheet and a back surface sheet, and a corrugated sheet arranged between them and extending in a specific direction. The material of the packaging container 100 is not limited to paper such as corrugated cardboard, and may be a material other than paper such as resin. In this specification, for convenience, the front-back, left-right, up-down directions are defined in the directions shown in the perspective view of FIG. Note that FIGS. 4 to 9 show a front view, a plan view, a right side view, a left side view, a rear view, and a bottom view of the packaging container 100, respectively.

As shown in FIGS. 2 and 3, the packaging container 100 includes one front plate 110, two side plates 112 and 114, two rear plates 116 and 120, and two bottom plates 118 and 122. , Equipped with.

The two side plates 112 and 114 each have a substantially right-angled isosceles triangle shape. The side plates 112 and 114 face each other with a gap. The left side plate 112 includes an oblique side 112a on the front surface side, a side 112b on the rear surface side, and a side 112c on the bottom surface side. The sides 112b and 112c are substantially equal. The angles formed by the sides 112b and 112c are right angles. The right side plate 114 includes an oblique side 114a on the front surface side, a side 114b on the rear surface side, and a side 114c on the bottom surface side. The sides 114b and 114c are substantially equal. The angles formed by the sides 114b and 114c are right angles.

The plates 110, 116, 118, 120, and 122 each have a substantially rectangular shape. The widths of the plates 110, 116, 118, 120, 122 in the left-right direction are substantially the same. The vertical width of the plates 110, 116, 120 is larger than the horizontal width. The width of the bottom plates 118 and 122 in the front-rear direction is larger than the width in the left-right direction. The opposing long sides 110a and 110b of the front plate 110 are rotatably connected to the hypotenuse 112a of the left side plate 112 and the hypotenuse 114a of the right side plate 114, respectively. As described above, in this embodiment, the hypotenuses 112a and 114a connected to the opposing long sides 110a and 110b of the front plate 110 are the longest of the three sides of the side plates 112 and 114. As a result, the connecting portion can be made longer than the side connecting to the long sides 110a and 110b is not the longest side of the three sides of the side plates 112 and 114, and when the packaging container 100 is assembled. The gap between the plates can be reduced.

The front plate 110 is arranged between the hypotenuses 112a and 114a. The rear plate 116 is rotatably connected to the side 112b of the left plate 112. The rear plate 120 is rotatably connected to the side 114b of the right plate 114. The rear plates 116 and 120 are arranged between the sides 112b and 114b and extend between the sides 112b and 114b over a length of more than half the distance between the sides 112b and 114b. The bottom plate 118 is rotatably connected to the side 112c of the left plate 112. The bottom plate 122 is rotatably connected to the side 114c of the right side plate 114. The bottom plates 118 and 122 are arranged between the sides 112c and 114c and extend between the sides 112c and 114c over a length of more than half the distance between the sides 112c and 114c. In the state of the blank 100a, the plates 110, 116, 118, 120 and 122 are separated from each other.

An opening 111 is formed over the front plate 110 and the side plates 112 and 114 (that is, straddling the hypotenuses 112a and 114a). The opening 111 has a square shape with rounded corners. The four sides of the opening 111 are arranged at an angle of 45 degrees with respect to the hypotenuses 112a and 114a. The opening 111 is recognized to have a substantially hexagonal shape when the packaging container 100 is viewed from the front or top (see FIGS. 4 and 5), and has a substantially triangular shape when the packaging container 100 is viewed from the side. Then, it is recognized (see FIGS. 6 and 7). A transparent or semi-transparent film (not shown) is stretched over the opening 111. Therefore, the products inside the packaging container 100 can be visually recognized from the outside of the packaging container 100. Since the opening 111 is formed over the front plate 110 and the side plates 112 and 114, it is possible to make the product easier to see as compared with the case where the opening is formed only on the front plate 110, for example.

How to assemble the packaging container 100 will be described. A flap 134 is rotatably connected to the rear side of the bottom plate 118. The flap 134 has a substantially trapezoidal shape. The bottom plate 118 is bent at a right angle along the side 112c, the rear plate 116 is bent at a right angle along the side 112b, and then the flap 134 is glued to the inside of the rear plate 116. A flap 136 is rotatably connected to the lower side of the rear plate 120. The flap 136 has a substantially trapezoidal shape. After the rear plate 120 is bent at right angles along the sides 114b and the bottom plate 122 is bent at right angles along the sides 114c, the flap 136 is glued to the inside of the bottom plate 122.

Next, the rear plate 120 is superposed on the outside of the rear plate 116, and the bottom plate 122 is superposed on the outside of the bottom plate 118 (see FIG. 10). In this case, the left ends of the rear plates 116 and 120 overlap, and the right ends of the rear plates 116 and 120 overlap. The left ends of the bottom plates 118 and 122 overlap, and the right ends of the bottom plates 118 and 122 overlap. Further, the entire surface of the rear plate 116 overlaps the rear plate 120, and the entire surface of the bottom plate 118 and the entire surface of the bottom plate 122 overlap. Further, the tag plate 132 rotatably connected to the short side 110c on the lower side of the front plate 110, the front end 118a of the bottom plate 118, and the front end 122a of the bottom plate 122 overlap each other. The tag plate 132 and the front ends 118a and 122a extend to the outside of the packaging container 100. Information such as the name and price of the product in the packaging container 100 can be described on the tag plate 132.

The folding plate 130 is rotatably connected to the short side 110d on the upper side of the front plate 110. The folding plate 130 has a substantially triangular shape. The folding plate 130 is folded outside the rear plate 120, and the insertion portion 130a at the lower end of the folding plate 130 is inserted into the insertion port 120a at the upper end of the rear plate 120 (see FIG. 8).

FIG. 11 shows the folding structure of the blank 100a. The blank 100a is delivered to the store from the manufacturer of the blank 100a in a folded state as shown in FIG. In FIG. 11, the flap 134 is adhered to the rear plate 116, and the flap 136 is adhered to the bottom plate 122. In FIG. 11, the rear plate 116 is bent along the folding curve 116a, and the bottom plate 122 is bent along the folding curve 122b. By compactly folding the blank 100a in this way, the convenience at the time of delivery of the blank 100a is improved. Further, since the packaging container 100 can be compactly folded after the consumer takes out the product from the packaging container 100, the convenience of the consumer is improved.

(Effect of the first embodiment)
12 and 13 show blanks 200a and 300a in which the packaging containers of the first comparative example and the second comparative example are developed, respectively. The packaging containers of the first and second comparative examples have a triangular prism shape like the packaging container 100 of the present embodiment. However, in the first and second comparative examples, unlike the present embodiment, the front plate, the rear plate, and the bottom plate are not all separated from each other.

As shown in FIG. 12, the packaging container of the first comparative example includes one front plate 210, two side plates 212 and 214, one rear plate 216, and two bottom plates 218 and 222. , Equipped with. The side plates 212 and 214 have a right-angled triangular shape. The two opposing sides of the rear plate 216 are connected to the sides 212a and 214a of the side plates 212 and 214. One side of the bottom plate 218 is connected to the side 212b of the side plate 212. One side of the bottom plate 222 is connected to the side 214b of the side plate 214. The front plate 210 is connected to the rear plate 216. In the packaging container of the first comparative example, the total length of the packaging container in the unfolded state has a total length of the length of the rear plate 216 in the longitudinal direction and the length of the front plate 210 in the longitudinal direction. As a result, if the packaging container is to be stored in an unfolded state, a long storage space must be prepared. On the other hand, in this embodiment, as shown in FIG. 3, since the rectangular plates 110, 116, 118, 120, 122 are arranged around the side plates 112, 114, the plates 110, 116, 118, 120 , 122 are not arranged side by side in the longitudinal direction thereof. As a result, in this embodiment, the overall length of the packaged container in the unfolded state can be suppressed as compared with the first comparative example.

As shown in FIG. 13, the packaging container of the second comparative example includes one front plate 310, two side plates 312, 314, two rear plates 316, 318, and one bottom plate 322. , Equipped with. The side plates 312 and 314 have a right-angled triangular shape. The two opposing sides of the front plate 310 are connected to the hypotenuses 312a and 314a of the side plates 312 and 314. One side of the rear plate 316 is connected to the side 314b of the side plate 314. One side of the rear plate 318 is connected to the side 312b of the side plate 312. The bottom plate 322 is connected to the front plate 310. In this way, the bottom plate 322 is arranged so as to project from the other plates. Therefore, as in the case of the first comparative example, in this embodiment, the overall length of the packaged container in the unfolded state can be suppressed as compared with the second comparative example.

Further, as shown in FIG. 12, in the packaging container of the first comparative example, the insertion portion 230 connected to the front plate 210 is inserted into the insertion port 222a of the bottom plate 222. The insertion portion 232a of the flap 232 connected to the front plate 210 is inserted into the insertion port 212d of the side plate 212. The insertion portion 234a of the flap 234 connected to the front plate 210 is inserted into the insertion port 214d of the side plate 214. The insertion portion 236 connected to the bottom plate 222 is inserted into the insertion port 218a of the bottom plate 218. That is, four insertions are required to form the packaging container of the first comparative example. On the other hand, as shown in FIG. 3, in the packaging container 100 of this embodiment, the insertion portion 130a may be inserted into the insertion port 120a. That is, in this embodiment, the load of the work of forming the packaging container can be reduced as compared with the first comparative example.

Further, as shown in FIG. 13, in the packaging container of the second comparative example, the insertion portion 332a of the flap 332 connected to the front plate 310 is inserted into the insertion port 316a of the rear plate 316. The insertion portion 334 connected to the bottom plate 322 is inserted into the insertion port 316b of the rear plate 316. That is, two insertions are required to form the packaging container of the second comparative example. Therefore, in this embodiment, the load of the work of forming the packaging container can be reduced as compared with the second comparative example.

Further, in the first and second comparative examples of FIGS. 12 and 13, it is difficult to design so that both the rear plate and the bottom plate are doubled because the rectangular plate is not connected to one side of each side plate. Is. On the other hand, in this embodiment, since both the rear plates 116 and 120 and the bottom plates 118 and 122 are doubled, the strength of the packaging container 100 can be improved.

(Second Example)
The points different from the first embodiment will be mainly described. The appearance of the packaging container of this embodiment is the same as that of the first embodiment (see FIGS. 2, 3 to 9). FIG. 14 shows a blank 400a in which the packaging container is unfolded. The packaging container includes one front plate 110, two side plates 112 and 114, two rear plates 416 and 120, and two bottom plates 418 and 122. Reference numerals 110, 112, 114, 120 and 122 are the same as those of reference numerals 110, 112, 114, 120 and 122 in FIG. Hereinafter, the description of the configuration having the same reference number as that in FIG. 3 will be omitted.

The rear plate 416 is different from the rear plate 116 in FIG. 3 only in that it does not have a folding curve. The bottom plate 418 is different from the bottom plate 118 in FIG. 3 only in that it includes a folding curve 418b. The front end 418a is the same as the front end 118a in FIG. A flap 436 is rotatably connected to the lower side of the rear plate 120. The flap 436 is different from the flap 136 in that it has a wide width in the front-rear direction.

FIG. 15 shows the folding structure of the blank 400a. In FIG. 15, the flap 134 is glued to the rear plate 416 and the flap 436 is glued to the bottom plate 122. Further, the bottom plate 418 is bent along the folding curve 418b, and the bottom plate 122 is bent along the folding curve 122b. By compactly folding the blank 400a in this way, convenience at the time of delivery and convenience for consumers are improved.

Also in this embodiment, since the rectangular plates 110, 416, 418, 120, and 122 are arranged around the side plates 112 and 114, the total length of the packaged container in the unfolded state can be suppressed.

(Third Example)
FIG. 16 shows a perspective view of the triangular prism-shaped packaging container 500. The packaging container 500 is used for storing various products (for example, one piece of pizza, foods such as quiche and fried chicken, and miscellaneous goods) and displaying them in a store. In this embodiment, unlike the first and second embodiments, two triangular plates are arranged in the vertical direction. FIG. 17 shows a blank 500a in which the packaging container 500 is unfolded. 18 to 23 show a front view, a plan view, a right side view, a left side view, a rear view, and a bottom view of the packaging container 500, respectively.

The right side plates 518 and 522 are arranged between the sides 512b and 514b.

How to assemble the packaging container 500 will be described. A flap 534 is rotatably connected to the front side of the right plate 518. The flap 534 has a substantially trapezoidal shape. The right side plate 518 is bent at a right angle along the side 512b, the front plate 516 is bent at a right angle along the side 512a, and then the flap 534 is glued to the inside of the front plate 516. A flap 536 is rotatably connected to the right side of the front plate 520. The flap 536 has a substantially trapezoidal shape. The front plate 520 is bent at a right angle along the side 514a, the right side plate 522 is bent at a right angle along the side 514b, and then the right side plate 522 is glued to the flap 536 with an adhesive applied to its inner front end 522a. Will be done.

Next, the front plate 520 is superposed on the outside of the front plate 516, and the right side plate 522 is superposed on the outside of the right side plate 518 (see FIG. 16). In this case, a part of the front plate 516 and 520 overlaps near the center in the vertical direction of the packaging container 500, and a part of the right side plate 518 and 522 overlaps near the center. Further, the flap 532 rotatably connected to the front plate 516 and the flap 535 rotatably connected to the right side plate 518 are folded inward. Then, the insertion portion 516a at the upper right end of the front plate 516 is inserted into the insertion port 520a at the lower right end of the front plate 520.

FIG. 24 shows the folding structure of the blank 500a. In FIG. 24, the flap 534 is glued to the front plate 516 and the front end 522a is glued to the flap 536. In FIG. 24, the right side plate 518 is bent along the folding curve 518a, and the right side plate 522 is bent along the folding curve 522b. By compactly folding the blank 500a in this way, convenience at the time of delivery and convenience for consumers are improved.

Also in this embodiment, since the rectangular plates 510, 516, 518, 520, and 522 are arranged around the triangular plates 512 and 514, the total length of the packaging container 500 in the unfolded state can be suppressed. can.
