[1. First embodiment]
[1-1. composition]
As shown in FIG. 1, the support body 5 according to this embodiment has an elongated shape and functions as a spoon handle. The support 5 is assembled from a single sheet 50 (see FIG. 2). The support 5 and the sheet 50 are made of paper, for example.

A dish-shaped head 4 having a scooping function (predetermined function) is provided on one side (hereinafter also referred to as the "tip side") of the support body 5 in the longitudinal direction D1. Here, a support 5 integrally formed with the head 4 is illustrated as an instrument. That is, the support 5 and the head 4 illustrated here are instruments formed of a single sheet 50.
The support body 5 includes a main body part 1 extending in the longitudinal direction D1, a lid part 2 connected to the main body part 1 on the other side of the longitudinal direction D1 (hereinafter also referred to as "terminal side"), and a tip end from the lid part 2. It is provided with an insertion part 3 bent to the side. In the support body 5, the main body part 1 forms a handle, and the lid part 2 forms the end of the handle.

The main body portion 1 is provided with a pair of side portions 12 and 13 that are connected to each other via a base portion 11 that extends in the longitudinal direction D1. The side parts 12 and 13 are bent in the same direction from the base 11 (one side in the thickness direction D3 perpendicular to both the longitudinal direction D1 and the transverse direction D2), and face each other in the transverse direction D2. In this embodiment, the main body 1 has a linearly formed base 11 and side parts 12 and 13, and the cross section along the longitudinal direction D1 and the transverse direction D2 has an approximately V-shape (V-shaped cross section). exemplify.

In addition, the side parts 12 and 13 are closer to each other toward the distal side, and are in contact with each other at the most distal position (the position covered by the lid part 2). Furthermore, a head 4 is connected to the tip side of the side surfaces 12 and 13 in this embodiment.
Hereinafter, when the pair of side surfaces 12 and 13 are to be distinguished from each other, one side surface 12 located on the near side (one side in the lateral direction D2) in FIG. 1, the other side surface portion 13 located on the back side (the other side in the transverse direction D2) is also referred to as the "second side surface portion 13."

A slit 14 is formed in at least the first side surface portion 12 of the pair of side surface portions 12 and 13. In this embodiment, the main body part 1 in which the slit 14 is formed only in the first side surface part 12 is illustrated. In other words, the slit 14 is not formed in the second side surface portion 13 of this embodiment.
The slit 14 extends from the middle part of the first side surface portion 12 to the edge 15 on the opposite side to the base 11 (hereinafter also referred to as "side edge 15"). Here, an arcuate slit 14 that is gently convex toward the distal end is illustrated.

The first side surface portion 12 of this embodiment is slightly bent at a folding line 16 that extends linearly, and is slightly convex toward the outside in the transverse direction D2. Specifically, the folding line 16 is a straight line that connects the most distal position of the connecting portion between the first side surface portion 12 and the base portion 11 and the end of the slit 14 on the base portion 11 side. It extends to the side edge 15. By being bent along the folding line 16 as described above, the first side surface portion 12 is suppressed from bulging in a portion located closer to the side edge 15 (on one side in the thickness direction D3) than the folding line 16.

Similarly, the second side surface portion 13 of this embodiment is slightly bent at a fold line 17 (see FIG. 2) that is mirror-symmetrical to the fold line 16 of the first side surface portion 12, and is directed outward in the lateral direction D2. It is slightly convex. By being bent along the folding line 17 in this manner, the second side surface portion 13 is suppressed from bulging in a portion located closer to the side edge 15 than the folding line 17 (one side in the thickness direction D3).
The lid part 2 is disposed on the distal side of the main body part 1 and covers the main body part 1 from the distal side. In this embodiment, the lid part 2 that is connected to the second side part 13 (one of the pair of side parts 12 and 13) is illustrated. The lid part 2 connected to the second side part 13 covers the distal edge of the first side part 12 so that it cannot be seen from the outside.

The insertion part 3 is inserted into the slit 14 from the outside of the main body part 1 in order to maintain the support body 5 in a three-dimensional shape (assembled state). The insertion part 3 is locked to the main body part 1 by being inserted into the slit 14.
The support body 5 is provided with the same number of insertion parts 3 as the slits 14. Since the support body 5 of this embodiment is provided with only one slit 14, only one insertion portion 3 is also provided. Furthermore, in the support body 5 of this embodiment, since the slit 14 is provided in the first side surface portion 12, the insertion portion 3 is inserted into the slit 14 from the outside of the first side surface portion 12. Here, the insertion portion 3 is illustrated as having a tapered shape (triangular shape in this embodiment) in order to improve insertion into the slit 14.

The insertion part 3 of this embodiment has a stepped part 31 that is locked in the slit 14. The stepped portion 31 is formed at the edge of the insertion portion 3 on the base portion 11 side. The stepped portion 31 prevents the insertion portion 3 from coming off by being caught in the slit 14.
Further, the insertion portion 3 of this embodiment is slightly bent at a folding line 32 extending in an arc shape similar to the slit 14, and is slightly convex toward the outside in the lateral direction D2. By bending the insertion portion 3 along the folding line 32 in this manner, a portion closer to the insertion end side (on the right side in FIG. 1) than the folding line 32 easily enters the inside of the first side surface portion 12.

FIG. 2 is a plan view of the sheet 50 assembled into a spoon to which the support 5 of the present embodiment is applied (a developed view of the spoon to which the support 5 is applied). Hereinafter, among the directions along the extending surface of the sheet 50, the direction in which the base portion 11 extends is also referred to as the vertical direction D4, and the direction orthogonal to the vertical direction D4 is also referred to as the horizontal direction D5. With the base 11 as a reference, the longitudinal direction D4 and the lateral direction D5 of the sheet 50 correspond to the longitudinal direction D1 and the lateral direction D2 of the support body 5, respectively.

In the seat 50, a base portion 11 is provided at the center in the lateral direction D5, and side portions 12 and 13 are connected to both sides of the base portion 11 in the lateral direction D5. Further, a head 4 is connected to one side of the base portion 11 and the side portions 12 and 13 in the vertical direction D4 (corresponding to the distal end side of the support portion 5). Furthermore, the lid portion 2 is continuously provided on the other side of the second side surface portion 13 in the vertical direction D4 (corresponding to the distal end side of the support portion 5). Further, an insertion portion 3 extends from the lid portion 2 toward the other side in the vertical direction D4.
The base 11 and folding lines 16, 17, and 32 of the sheet 50 are all configured with ruled lines (grooves) that assist folding. Furthermore, ruled lines are also provided at the boundaries between each of the side parts 12 and 13 and the head 4. In FIG. 2 and FIGS. 4 and 6 described later, ruled lines are shown as thin lines.

In the sheet 50 of the present embodiment, ruled lines 21 (hereinafter also referred to as "lid ruled lines 21") are provided in a portion corresponding to the lid portion 2. The lid ruled line 21 has an end on the base 11 side (the right side in FIG. 2) that is aligned with the end of the base 11 (the part where the folding lines 16 and 17 connect) according to the thickness dimension of the sheet 50. It is separated to the other side in the vertical direction D4. The lid ruled line 21 is arranged at the most distal side in the support body 5.

[1-2. Action and effect]
(1) According to the support body 5, the support body 5 is maintained in a three-dimensional state by inserting the insertion part 3 bent from the lid part 2 connected to the main body part 1 into the slit 14, so that the support body 5 can be maintained in a three-dimensional state. The gripability (ease of holding) of the body 5 can be improved. As a result, even if the utensil to which the support 5 is applied (a spoon in this embodiment) is placed on a table or the like, the support 5 is maintained in a three-dimensional state, making it easy to hold the utensil in the hand again. Become. In addition, since the lid part 2 covers the main body part 1 from the distal end side, it is possible to prevent the user's fingers and foreign objects (such as dirt and moisture) from entering the main body part 1 from the distal end side, so that unintentional insertion can occur. It is possible to suppress the part 3 from coming off. Therefore, in the support body 5 assembled from a single sheet 50, deterioration in shape retention and gripability can be suppressed.

(2) The slit 14 is formed only in the first side surface portion 12, the lid portion 2 is connected to one of the pair of side surface portions 12, 13 (in this embodiment, the second side surface portion 13), and the insertion portion 3 According to the support body 5 in which only one is provided, the main body part 1 can be maintained in a three-dimensional state with one slit 14 and one insertion part 3. Therefore, compared to a case where a plurality of slits 14 and insertion portions 3 are provided, the grip of the support body 5 can be improved with a simple structure. Moreover, according to the main body part 1 in which the slit 14 is formed only in one of the side parts 12 and 13 (but not in the other), compared to the case in which the slit 14 is formed in both the side parts 12 and 13. Therefore, it is possible to suppress a decrease in rigidity, and since the number of slits 14 is reduced, it is possible to suppress intrusion of foreign matter into the main body portion 1 through the slits 14.

(3) According to the support body 5 in which the lid part 2 is connected to the second side part 13 and the insertion part 3 is inserted into the slit 14 from the outside of the first side part 12, the insertion part 3 is connected to the lid part 13. It becomes possible to insert it into the slit 14 by simply bending it once toward the outside of the first side surface portion 12 in which the slit 14 is formed. Therefore, the ease of assembling the support body 5 into a three-dimensional state (hereinafter also referred to as "assembly work") can be improved.

(4) According to the main body 1 having a V-shaped cross section with the linearly formed base 11 and the pair of side surfaces 12 and 13, the support body 5 has width in the transverse direction D2; Although the support body 5 has a three-dimensional shape, the dimension (width dimension) in the transverse direction D2 can be suppressed on the base 11 side. Therefore, while improving gripability of the support body 5, it also contributes to downsizing.

(5) According to the insertion part 3 having the stepped part 31, the inserted state in the slit 14 is easily maintained by the stepped part 31 being locked in the slit 14, so that the support body 5 can be made more stable. can be maintained in a three-dimensional state. Therefore, deterioration in shape retention and gripability of the support body 5 can be further suppressed.

(6) If the side portions 12 and 13 are bent at the folding lines 16 and 17, respectively, and thereby convex outward in the transverse direction D2, the portion closer to the side edge 15 than the folding lines 16 and 17 In this case, the bulge of the main body portion 1 in the lateral direction D2 can be suppressed. Therefore, it contributes to making the support body 5 more compact, and since the insertion part 3 can easily overlap on the outside of the side surfaces 12 and 13, the ease of inserting the insertion part 3 into the slit 14 can be improved. In addition, by improving the ease of insertion of the insertion part 3 in this way, the ease of assembly work is increased, and the support body 5 is maintained in a more stable three-dimensional state, so that the support body 5 can be easily inserted. Deterioration in shape retention and gripability can be further suppressed.

(7) If the insertion portion 3 is bent along the folding line 32 and forms a convexity toward the outside in the transverse direction D2, the portion closer to the insertion end than the folding line 32 is the first side surface portion 12. Since it becomes easier to enter the inside, the insertion part 3 can be easily inserted into the slit 14. By improving the ease of insertion of the insertion part 3 in this way, the ease of assembly work is improved as described above, and the support body 5 is more stably maintained in a three-dimensional state, so the support body 5 shape retention and gripability can be further suppressed.

(8) In the sheet 50 of this embodiment, the end of the lid ruled line 21 provided at the position corresponding to the lid 2 on the base 11 side is equal to the thickness of the sheet 50 with respect to the distal end of the base 11. Since they are spaced apart accordingly, the lid portion 2 can be appropriately disposed on the distal side of the base portion 11 in the support body 5. As a result, the main body 1 is more reliably covered by the lid 2 from the distal end, so that it is possible to more reliably prevent the user's fingers and foreign objects from entering the main body 1 from the distal end.

[2. Second embodiment]
[2-1. composition]
As shown in FIG. 3, the support body 6 according to this embodiment differs from the support body 5 described in the first embodiment mainly in the configuration of the insertion part 3. Hereinafter, elements that are the same as or correspond to those described in the first embodiment will be denoted by the same reference numerals, and redundant explanation will be omitted.

In the main body 1 of this embodiment, one of the pair of side surfaces 12 and 13 located on the front side in FIG. 3 is the first side surface section 12 provided with the slit 14, and the one located on the back side in FIG. The other side is the second side surface portion 13 in which the slit 14 is not provided. The slit 14 of this embodiment is formed in an arcuate shape that is gently convex toward the side edge 15 in the intermediate portion of the first side surface portion 12 (between the base 11 and the side edge 15).

A linear auxiliary slit 18 extending from the slit 14 to the side edge 15 is formed in the first side surface portion 12 of this embodiment. The auxiliary slit 18 is provided in a region of the first side surface portion 12 where a portion of the insertion portion 3 (a folded portion 33 to be described later) overlaps. The auxiliary slit 18 has a function of making it easier to deform the first side surface portion 12 on which the folded portion 33 overlaps. In addition, in the side parts 12 and 13 of this embodiment, the folding lines 16 and 17 explained in the first embodiment are all omitted.

The lid part 2 of this embodiment is connected to the first side part 12 in which the slit 14 is provided. The lid part 2 connected to the first side part 12 covers the distal edge of the second side part 13 so that it cannot be seen from the outside.
The insertion part 3 of this embodiment has an overlapping part 34 that is bent from the lid part 2 and overlaps the outside of the second side part 13, and a position facing the base part 11 via the side parts 12 and 13 (the thickness of the base part 11 is The folded portion 33 is folded back from the overlapping portion 34 to the outside of the first side surface portion 12 in the direction D3 (one side in the direction D3). The folded portion 33 is inserted into the slit 14 from the outside of the first side surface portion 12.

Here, the folded portion 33 is folded toward the base portion 11 by being folded stepwise along a plurality of folding lines 35 (see FIG. 4) extending along the longitudinal direction D1 near the side edges 15 of the side portions 12 and 13. The folded insertion part 3 is illustrated. In this way, the folded part 33 of the insertion part 3 is folded back from the overlapping part 34 on one side of the base part 11 in the thickness direction D3, so that a part of the side edge 15 of the side parts 12 and 13 is folded back in the thickness direction D3. Cover from one side.

The folded portion 33 of this embodiment is slightly bent at a folding line 36 extending in the longitudinal direction D1, and is slightly convex toward the outside in the transverse direction D2. By bending the folded portion 33 along the folding line 36 in this manner, a portion closer to the insertion end (upper side in FIG. 3) than the folding line 36 easily enters inside the first side surface portion 12.

The support body 6 of this embodiment is assembled from a single sheet 60 shown in FIG. The seat 60 differs from the seat 50 of the first embodiment mainly in the configuration of the insertion portion 3 as described above. In the sheet 60, the insertion section 3 having the overlapping section 34 and the folded section 33 has a substantially rectangular shape. Moreover, the folding lines 35 and 36 provided in the insertion part 3 extend parallel to each other, and the folding line 36 for insertion of the folding part 33 is on the other side of the vertical direction D4 ( located outside). Note that the base 11, the lid ruled line 21, and the folding lines 35, 36 in the sheet 60 are all configured with ruled lines (grooves) that assist folding.

[2-2. Action and effect]
(1) According to the support body 6 of this embodiment, the lid part 2 is connected to the first side part 12, and the insertion part 3 is connected to the overlapping part 34 which overlaps the outside of the second side part 13. Since it has a folded part 33 which is folded back to the outside of the first side part 12 and inserted into the slit 14, the main body part 1 can be sandwiched between the overlapping part 34 and the folded part 33 from both sides in the lateral direction D2. Thereby, the support body 6 can be maintained in a three-dimensional state more stably. Therefore, deterioration in shape retention and gripability of the support body 6 can be further suppressed.

Moreover, according to the insertion part 3 of this embodiment, since the folded part 33 is folded back from the overlapping part 34 at a position facing the base 11 via the side parts 12 and 13, the main body part 1 is placed on the side opposite to the base 11. It can also be covered from (one side in the thickness direction D3). Thereby, it is possible to prevent the user's fingers and foreign objects from entering into the main body 1 through the gap between the side edges 15. Therefore, deterioration in shape retention and gripability of the support body 6 can be further suppressed.

(2) In the first side surface portion 12 in which the auxiliary slit 18 extending from the slit 14 to the side edge 15 is formed, the area where the folded portion 33 overlaps is easily deformed by the auxiliary slit 18, The ease of insertion of the section 33 can be improved. By improving the ease of inserting the folded part 33 in this way, the ease of assembly work is improved, and the support body 6 is more stably maintained in a three-dimensional state, so the shape retention of the support body 6 is improved. It is possible to further suppress the deterioration of grip performance and gripability.

(3) According to the insertion part 3 in which the folded part 33 is folded back toward the base 11 side by being folded stepwise along the plurality of folding lines 35, the folded part 33 is easily folded back appropriately from the overlapping part 34. . This makes it easier for the folded portion 33 to appropriately overlap the outside of the first side surface portion 12, thereby increasing the ease of inserting the folded portion 33 into the slit 14.

(4) If the folded portion 33 is bent at the folded line 36 and thereby forms a convexity outward in the transverse direction D2, the portion closer to the insertion end than the folded line 36 is inside the first side surface portion 12. This makes it easier to insert the folded portion 33 into the slit 14.
(5) In addition, according to the support body 6 of this embodiment, the same operation and effect can be obtained from the same structure as the support body 5 of the first embodiment.

[3. Third embodiment]
[3-1. composition]
As shown in FIG. 5, the support body 7 according to the present embodiment has different shapes of the base 11 and the lid part 2, and the insertion The main difference is the number of parts 3.

Here, a main body part 1 having a channel shape with a base part 11 formed in a planar shape and a pair of side parts 12 and 13 is illustrated. The pair of side surfaces 12 and 13 are arranged parallel to each other at least at their distal ends, and are spaced apart from each other at the most distal position (the position covered by the lid part 2).
The side parts 12 and 13 of this embodiment are formed symmetrically with respect to each other. The slit 14 is formed in each of the pair of side parts 12 and 13. Specifically, among the pair of side surfaces 12 and 13, one first side surface 12 located on the near side in FIG. 5 and the other second side surface 13 located on the back side in FIG. A slit 14 is formed in.

The slit 14 of this embodiment extends from the boundary between the base 11 and the side parts 12 and 13 to the intermediate part of the side parts 12 and 13, respectively. Here, an arc-shaped slit 14 that is gently convex toward the side edge 15 is illustrated. Note that the folding lines 16 and 17 described in the first embodiment are also omitted from the side surfaces 12 and 13 of this embodiment.
The lid part 2 of this embodiment is connected to the base part 11. The lid part 2 connected to the base part 11 covers the distal edges of the side parts 12 and 13 so that they cannot be seen from the outside. That is, the lid part 2 covers the hollow part between the pair of side parts 12 and 13 from the distal side.

Since the support body 7 of this embodiment is provided with two (one pair) of slits 14 as described above, two (one pair) of insertion portions 3 are also provided. The pair of insertion portions 3 are connected to both sides of the lid portion 2 in the lateral direction D2. In this embodiment, since the slits 14 are provided in each of the side surfaces 12 and 13, the pair of insertion portions 3 are inserted into the slits 14 from the outside of the pair of side surfaces 12 and 13, respectively. Here, an example is shown in which the corner portions on the base 11 side and the tip side of the rectangular insertion portion 3 are inserted into the slit 14 and disposed inside the side portions 12 and 13.

The support body 7 according to this embodiment is assembled from a single sheet 70 shown in FIG. The sheet 70 differs from the sheets 50 and 60 of the first embodiment and the second embodiment mainly in the shapes of the base portion 11 and the lid portion 2 and the number of insertion portions 3 as described above. The sheet 70 is formed symmetrically with respect to a center line C in the lateral direction D5.
Both the base 11 and the lid 2 in the sheet 70 have a rectangular shape that is longer in the vertical direction D4 than in the horizontal direction D5. In the seat 70, the base portion 11 and the lid portion 2 are arranged in series in the vertical direction D4.

The lid portion 2 and the pair of insertion portions 3 are connected in the lateral direction D5. More specifically, the insertion portions 3 are connected to both sides of the lid portion 2 in the lateral direction D5. Note that ruled lines (grooves) to assist in bending are provided at each boundary between the base 11 and the side parts 12 and 13, at each boundary between the base 11 and the lid part 2, and at each boundary between the lid part 2 and the insertion part 3. It is being

Since they are inserted into the slits 14 formed in each, the main body part 1 can be sandwiched between the pair of insertion parts 3 from both sides in the lateral direction D2. Thereby, the support body 7 can be maintained in a three-dimensional state more stably. Therefore, deterioration in shape retention and gripability of the support body 7 can be further suppressed.

(2) According to the main body part 1 which forms a channel shape with the base part 11 formed in a planar shape and the pair of side parts 12 and 13, the dimension (width dimension) in the transverse direction D2 of the support body 7 is the thickness direction D3. Since it is secured over the entire area, the grip of the support body 7 can be improved.

The utensils to which the supports 5, 6, and 7 are applied are not limited to the spoons exemplified in the above embodiments. Furthermore, the supports 5, 6, and 7 may be formed separately from the head 4. That is, by connecting the supports 5, 6, and 7, which are formed separately from the head 4, to the head 4, a device such as a spoon may be constructed. Note that the supports 5, 6, and 7 are not limited to being made of paper, and may be made of, for example, plastic.

The step part 31 of the insertion part 3 may be omitted from the support body 5 of the first embodiment, and the auxiliary slit 18 may be omitted from the support body 6 of the second embodiment. Moreover, the base 11 may be formed in a planar shape in the supports 5 and 6 of the first embodiment and the second embodiment, and the base 11 may be formed in a linear shape in the support 7 of the third embodiment. good.

The shape of the lid portion 2 is also not particularly limited. The lid portion 2 may be formed in a triangular shape, for example, to cover the main body portion 1, which has a V-shaped cross section at the distal end, from the distal end.
