[0003] [Patent Document 1] Japanese Patent Publication No. 2022-44360 Summary of the Invention [Problem to be solved by the invention]

[0004] If the inclined wall has a side wall portion that is not directly connected to the base, such as a side wall that is not directly connected to the bottom plate, it is more likely to bend than a side wall that is connected to the bottom plate, such as the outer wall described above.

[0005] This specification proposes a technique that can suppress bending of a side wall that has a portion that is not directly connected to a base. [Means for solving the problem]

[0006] A first aspect disclosed in the present specification is a packaging device. The packaging device may include a base and a side wall surrounding the base, the side wall including a first side wall extending from the base, a second side wall connected to the first side wall via a fold line and inclined relative to the first side wall, a third side wall extending from the base and inclined relative to the second side wall, and a first extension piece extending from the second side wall along an inner side of the third side wall, the first side wall including a first outer plate connected to the base via a fold line and a first inner plate connected to an edge of the first outer plate opposite the base via a fold line and arranged to overlap the first outer plate, and the second side wall including a second outer plate connected to the first outer plate via a fold line and a second inner plate connected to the first inner plate via a fold line and arranged to overlap the second outer plate.

[0007] In this packaging device, the second side wall connected to the first side wall via a fold line has a structure in which multiple plates including a second outer plate and a second inner plate are stacked on top of each other, which makes it possible to prevent the second side wall from bending compared to when the second side wall is composed of a single side plate.

[0008] A second aspect disclosed in the present specification is the first aspect, wherein the first extension piece may extend from the second inner side plate along the third side wall.

[0009] The third side wall has a portion located outside the packaging device relative to the first extension piece. By extending the first extension piece from the second inner panel, the second outer panel can be positioned closer to the outside of the packaging device than when the first extension piece extends from the second outer panel. This reduces the step between the second side wall and the third side wall on the outer peripheral surface of the packaging device.

[0010] A third aspect disclosed in the present specification may be the first or second aspect, further comprising a fourth side wall arranged adjacent to the third side wall on the opposite side of the third side wall from the second side wall, and a second extension piece extending from the fourth side wall along the third side wall and connected to the first extension piece.

[0011] According to this configuration, by connecting the first extension piece and the second extension piece, the position of the first extension piece can be stabilized, and thus the position of the second side wall can be stabilized.

[0012] A fourth aspect disclosed in the present specification is any one of the first to third aspects, wherein the third side wall comprises a third outer plate connected to the base via a fold line, and a third inner plate connected to an edge of the third outer plate opposite the base via a fold line and arranged overlapping the third outer plate, and the first extension piece may be arranged between the third outer plate and the third inner plate.

[0013] This configuration can prevent the first extension piece from being exposed to the inside of the packaging device.

[0014] A fifth aspect disclosed in the present specification is, in any one of the first to fourth aspects, wherein the first extension piece extends from the second inner plate along the third side wall, and the third side wall comprises a third outer plate connected to the base via a fold line, and a third inner plate connected to an edge of the third outer plate opposite the base via a fold line and arranged overlapping the third outer plate, and the end face of the second outer plate facing the third outer plate may face the end face of the third outer plate facing the second outer plate.

[0015] This configuration can prevent the end faces of the second outer plate and the third outer plate from being exposed, thereby improving the design of the packaging device.

[0016] A sixth aspect disclosed in the present specification is a packaging container comprising a storage section and a lid section that closes the storage section, and at least one of the storage section and the lid section may be the packaging device according to any one of the first to fifth aspects.

[0017] By using a packaging device for at least one of the storage section and the lid section, the second side wall connected to the first side wall via a fold line has a structure in which multiple plates including a second outer plate and a second inner plate are stacked on top of each other, which makes it possible to prevent the second side wall from bending compared to when the second side wall is composed of a single side plate.

[0018] A seventh aspect disclosed in the present specification is a deployment body. The deployment body may be composed of a single flat plate, and may be capable of assembling the packaging device according to any one of the first to fifth aspects. [Brief explanation of the drawings]

[0020] (Example) The packaging container 10 shown in Fig. 1 is a container for storing an object. The packaging container 10 includes a storage section 20 and a lid section 60. As shown in Figs. 1 and 2, the packaging container 10 can be transitioned between a closed state in which the storage section 20 is sealed with the lid section 60, and an open state in which the storage section 20 is opened by removing the lid section 60 from the storage section 20.

[0021] In this embodiment, the up-down direction, the front-back direction, and the left-right direction are shown, including in the drawings. These up-down direction, the front-back direction, and the left-right direction are used to facilitate the explanation of this embodiment, and do not define the direction in which the packaging container 10 is used.

[0022] As shown in Fig. 2, the storage section 20 includes a bottom plate 30 having an octagonal flat plate and an octagonal cylindrical side wall section 21. As shown in Fig. 3, the lid section 60 includes a top plate 70 having an octagonal flat plate and an octagonal cylindrical side wall section 61. In the closed state, the side wall section 61 is disposed so as to surround the side wall section 21 from the outside.

[0023] (Storage section configuration) As shown in FIG. 4, the storage section 20 is assembled by folding the unfoldable body BL1, which is made of a single flat plate, along folding lines. In FIG. 4, adhesive areas where adhesive is applied on the side walls 22, 24 are represented by thin lines in a grid pattern. The folding lines are drawn with thin dashed lines. At least one of grooves, perforations, and slits is formed on the folding lines to facilitate folding. The unfoldable body BL1 is made of thin corrugated cardboard. The material of the unfoldable body BL1, i.e., the packaging container 10, is not limited to corrugated cardboard, and may be, for example, cardboard, resin, etc.

[0024] The storage section 20 includes a bottom plate 30 and side walls 21. The bottom plate 30 has an octagonal flat plate shape.

The side plate 22b has a rectangular flat plate shape extending over the entire length of the bottom plate 30 in the front-to-rear direction. The side plate 22a is connected to the edge of the side plate 22b opposite the bottom plate 30, i.e., the upper edge of the packaging container 10, via a fold line. The side plate 22a has a rectangular flat plate shape extending over the entire length of the edge of the side plate 22b. In the up-down direction of the packaging container 10, the side plate 22a is set to be slightly shorter than the side plate 22b.

[0026] A side wall 32 is connected to the front edge of the side wall 22. The side wall 32 includes two side plates 32a and 32b. The side plate 32b is connected to the front edge 22f of the side plate 22b via a bend line. The side plate 32b is connected to the side plate 22b along the entire length of the front edge 22f. The side plate 32b has approximately the same length as the edge 30e connecting the front edge 30b of the bottom plate 30 to the edge 30a. The side plate 32b has a rectangular flat plate shape. The side plate 32a is connected to the edge of the side plate 32b opposite the bottom plate 30, i.e., the upper edge of the packaging container 10, via a bend line. The side plate 32a has a rectangular flat plate shape that extends along the entire length of the edge of the side plate 32b. The side plate 32a is connected to the front edge 22e of the side plate 22a via a bend line. A notch is provided at the folding line between side plate 22a and side plate 32a so that the material is not compressed when folded. Side plate 32a is set slightly shorter than side plate 32b in the vertical direction of packaging container 10. Side plate 32a is set slightly shorter than side plate 22b to avoid folding piece 46a when storage section 20 is assembled.

[0027] A bent piece 46a, which is disposed between the side plate 32b and the bottom plate 30, is connected to the edge of the side plate 32b on the bottom plate 30 side via a bend line.

[0028] An extension piece 42a is connected via a bend to the edge of side plate 32a opposite to side plate 22a. The extension piece 42a has an engagement notch 42e on the edge opposite to side plate 32a. The engagement notch 42e is located in the center of side plate 32a in the up-down direction of the packaging container 10.

[0029] A side wall 38 is connected to the rear edge of the side wall 22. The side wall 38 has a configuration similar to that of the side wall 32. The side wall 38 includes side plates 38a and 38b similar to the side plates 32a and 32b. The side plate 38b has substantially the same length as the edge 30f connecting the rear edge 30d of the bottom plate 30 to the edge 30a. The side plate 38b is connected to the rear edge 22d of the side plate 22b. The side plate 38a is connected to the rear edge 22c of the side plate 22a. An extension piece 42b similar to the extension piece 42a is connected to the side plate 38a. A bent piece 46b similar to the bent piece 46a is connected to the side plate 38a and the side plate 38b via a bending line.

[0030] The side wall 26 is connected to the front edge 30d of the bottom plate 30 via a fold line. The side wall 26 includes two side plates 26a and 26b, a connecting piece 26c, and a bent piece 26d. The side plate 26b is connected to the edge 30d via a fold line. The side plate 26b is connected to the bottom plate 30 along the entire length of the edge 30d. The side plate 26b has a rectangular flat plate shape extending along the entire length of the bottom plate 30 in the left-right direction. The side plate 26a is connected to the edge of the side plate 26b opposite the bottom plate 30, i.e., the upper edge of the packaging container 10, via a connecting piece 26c. The side plate 26a has a rectangular flat plate shape extending along the entire length of the edge of the side plate 26b. In the up-down direction of the packaging container 10, the side plate 26a is set to be slightly shorter than the side plate 26b. A connecting piece 26c is connected between the side plate 26a and the side plate 26b via a bending line.

[0031] A bent piece 26d is connected to the edge of the side plate 26a opposite to the side plate 26b via a bending line. The bent piece 26d is disposed over the entire length of the side plate 26a in the left-right direction.

[0032] The side wall 24 is connected to the right edge 30c of the bottom plate 30 via a bend line. The side wall 24 has a configuration similar to that of the side wall 22. The side wall 24 has side plates 24a and 24b similar to the side plates 22a and 22b. Side walls 34 and 36 are connected to the front and rear edges of the side wall 24, respectively. The side wall 34 has a configuration similar to that of the side wall 32. The side wall 34 has side plates 34a and 34b similar to the side plates 32a and 32b. The side plate 34a is connected to the front edge 24e of the side plate 24a, and the side plate 34b is connected to the front edge 24f of the side plate 24b. The side wall 36 has a configuration similar to that of the side wall 38. The side wall 36 has side plates 36a and 36b similar to the side plates 38a and 38b. The side plate 36a is connected to the rear edge 24c of the side plate 24a, and the side plate 36b is connected to the rear edge 24d of the side plate 24b.

[0033] An extension piece 44a is connected to the front edge of the side plate 34a of the side wall 34. The extension piece 44a has an engagement notch 44e on the edge opposite to the side plate 34a. The engagement notch 44e is located in the center of the side plate 32a in the up-down direction of the packaging container 10. The engagement notch 44e has a shape that engages with the engagement notch 42e. An extension piece 44b is connected to the side plate 36a of the side wall 36. The extension piece 44b has a configuration similar to that of the extension piece 44a.

[0034] A bent piece 48a similar to bent piece 46a is connected via a bend line to the edge of side plate 34b on the bottom plate 30 side. Bent piece 48a is disposed between side plate 34b and the bottom plate 30. A bent piece 48b similar to bent piece 48a is connected via a bend line to side plate 36b.

[0035] The side wall 28 is connected to the rear edge 30d of the bottom plate 30 via a bent line. The side wall 28 has the same configuration as the side wall 26. The side wall 28 has side plates 26a, 26b, a connecting piece 26c, side plates 28a, 28b similar to the bent piece 26d, a connecting piece 28c, and a bent piece 28d.

[0036] (How to make the storage compartment) Next, a method for producing the storage section 20 from the deployable body BL1 will be described. As shown in Fig. 6, adhesive is applied to the bonding areas GL1, GL2, and GL3 of the side plates 22a, 32a, and 38a, and the side plate 22a is folded along the bending line between the side plates 22a and 22b to bond the side plates 22a and 22b together. As a result, the side wall 22 has a double structure in which the side plate 22a, which is arranged inside the packaging container 10, and the side plate 22b, which is arranged outside the packaging container 10, overlap each other.

[0037] At the same time that side plate 22a is folded, side plate 32a is folded along the folding line between side plates 32a and 32b, thereby bonding side plate 32a and side plate 32b together. Similarly, side plate 38a is folded along the folding line between side plates 38a and 38b, thereby bonding side plate 38a and side plate 38b together. As a result, side wall 32 has a double structure in which side plate 32a, which is positioned inside packaging container 10, and side plate 32b, which is positioned outside packaging container 10, overlap each other, and side wall 38 has a double structure in which side plate 38a, which is positioned inside packaging container 10, and side plate 38b, which is positioned outside packaging container 10, overlap each other.

[0038] Similarly, the right side walls 24, 34, 36 have a double structure, with the side plates 24a and 24b overlapping, the side plates 34a and 34b overlapping, and the side plates 36a and 36b overlapping.

[0039] Next, the edge 30a of the bottom plate 30 is bent, and the side wall 22 is raised relative to the bottom plate 30. The bent piece 46a is bent relative to the lower end of the side plate 32b, and the side plates 32a, 32b are bent relative to the side plates 22a, 22b along the edge 30e of the bottom plate 30. As a result, with the bent piece 46a positioned on the bottom plate 30, the side wall 32 is positioned along the edge 30c. Similarly, the bent piece 46b is bent relative to the lower end of the side plate 38b, and the side plates 38a, 38b are bent relative to the side plates 22a, 22b along the edge 30f of the bottom plate 30. As a result, with the bent piece 46b positioned on the bottom plate 30, the side wall 38 is positioned along the edge 30d.

[0040] Similarly, on the right side of the bottom plate 30, the edge 30c of the bottom plate 30 is bent to raise the side wall 24 relative to the bottom plate 30, and the bent pieces 48a, 48b and the side walls 34, 36 are bent in the same manner as the bent pieces 46a, 46b and the side walls 32, 38.

[0041] Further, the extension piece 42a is bent relative to the side plate 32a along the front edge 30b of the bottom plate 30, and the extension piece 44a is bent relative to the side plate 34a along the front edge 30b of the bottom plate 30. This brings the extension pieces 42a and 44a close to each other at the front edge 30b. The extension pieces 42a and 44a are engaged by inserting the engagement notch 42e of the extension piece 44a from above into the engagement notch 42e of the extension piece 44a. Similarly, the extension pieces 42b and 44b are bent relative to the rear edge 30d, and the engagement notch of the extension piece 44b is inserted from above into the engagement notch of the extension piece 44b, thereby engaging the extension pieces 42b and 44b. This forms the state shown in FIG. 7.

[0042] Next, at the front edge 30b, side plate 26b is raised relative to the bottom plate 30, and connecting piece 26c and side plate 26a are bent so that connecting piece 26c is positioned at the upper end of storage section 20, and side plate 26a and side plate 26b are positioned with extension pieces 42a and 44a sandwiched between them. Bent piece 26d is bent relative to side plate 26b so as to overlap with bottom plate 30 and come into contact with bottom plate 30. Side wall 26 has a double structure formed by side plates 26a and 26b, and is formed with extension pieces 42a and 44a sandwiched between side plates 26a and 26b.

[0043] Similarly, by bending the side plates 28a, 28b, connecting piece 28c, and bending piece 28d at the rear edge 30d in the same manner as the side plates 26a, 26b, connecting piece 26c, and bending piece 26d, the side wall 28 is configured as a double structure with the side plates 28a, 28b, and the extension pieces 42b, 44b sandwiched between the side plates 28a, 28b. The bending piece 28d is placed on top of the bottom plate 30. In this way, the storage compartment 20 is created.

[0044] As shown in FIG. 8 , in the storage unit 20, the side panel 32b located on the outer side of the side wall 32 and the side panel 26b located on the outer side of the side wall 26 are arranged at an angle relative to each other. The edge 50 of the side panel 32b and the edge 52 of the side panel 26b face each other at an angle relative to a position where they would face each other directly. In other words, the edges 50, 52 face each other at an acute angle. This configuration allows the edges 50, 52 to be positioned so that they are not easily visible from outside the storage unit 20. This improves the design of the storage unit 20. By extending the extension piece 42a arranged along the side panel 26b from the side panel 32a arranged inside the side panel 32b, the side panels 26b and 32b can be arranged without any step. This improves the design of the storage unit 20. A similar configuration exists between the side walls 34, 36, 38 and the side walls 26, 28.

[0045] Compared to the side walls 22, 24, 26, 28 that are connected to the bottom plate 30 via folding lines, the side walls 32, 34, 36, 38 are more likely to bend when subjected to a force that is directed from the outside to the inside of the storage section 20. By making the side walls 32, 34, 36, 38 have a double structure, the side walls 32, 34, 36, 38 can be made less likely to bend. By folding the folding pieces 46a, 46b, 48a, 48b that are connected to the side walls 32, 34, 36, 38 and adhering them to the bottom plate 30, the side walls 32, 34, 36, 38 can be made less likely to bend.

[0046] By arranging the extension pieces 42a, 42b, 44a, 44b, it is possible to prevent gaps from being formed between the side walls 22, 26, between the side walls 24, 26, between the side walls 24, 28, and between the side walls 22, 28.

[0047] By connecting the extension pieces 42a, 44a and also connecting the extension pieces 42b, 44b, the components 22, 24, 26, 28, 32, 34, 36, and 38 can be held against the bottom plate 30 without falling over.

[0048] The extension pieces 42a, 44a can be protected by sandwiching them between the side plates 26a, 26b of the side wall 26. Preventing the extension pieces 42a, 44a from being exposed can prevent the extension pieces 42a, 44a from disengaging. Similarly, the extension pieces 42b, 44b are protected by the side wall 28 and prevented from being exposed.

[0049] (Lid configuration) As shown in FIG. 5, the lid 60 is assembled by folding the deployable body BL2, which is made of a single flat plate, along the folding lines. In FIG. 5, the adhesive areas of the side walls 62, 64 where adhesive is applied are represented by thin, grid-like lines. The folding lines are drawn with thin, dashed lines. At least one of grooves, perforations, and slits is formed on the folding lines to make folding easier. The deployable body BL2 is made of the same material as the deployable body BL1. It is made of thin cardboard. The material of the deployable body BL2 is not limited to cardboard and may be, for example, cardboard, resin, etc., and may be different from that of the deployable body BL1.

[0050] The lid portion 60 has a top plate 70 and side wall portions 61 similar to the bottom plate 30 and side wall portions 21 of the storage portion 20. The top plate 70 has an octagonal flat plate shape similar to the bottom plate 30. The side wall portions 61 of the top plate 70 are connected to the bottom plate 30 via fold lines on both front and rear edges and on both left and right edges. The side wall portions 61 have eight side walls 62, 64, 66, 68, 72, 74, 76, and 78. In FIG. 5, the top surface of the top plate 70 faces upward in the packaging container 10. The adhesive regions of the side walls 62 and 64 are located on the undersides of FIG. 5.

[0051] Each of the side walls 62, 64 is connected to the top plate 70 in the left-right direction via a folding line. Each of the side walls 62, 64 has a configuration similar to each of the side walls 22, 24. Note that, in the up-down direction of the packaging container 10, each of the side walls 62, 64 is shorter than each of the side walls 22, 24. The side wall 62 has side plates 62a, 62b similar to the side plates 22a, 22b. Note that the side plates 62a, 62b are shorter than each of the side plates 22a, 22b. The side wall 64 has side plates 64a, 64b similar to the side plates 24a, 24b. Note that the side plates 64a, 64b are shorter than each of the side plates 24a, 24b. The side walls 62, 64 have similar shapes to each other.

[0052] Side walls 72 and 78 are connected to the front and rear edges of side wall 62, respectively. Side walls 74 and 76 are connected to the front and rear edges of side wall 64, respectively. Side walls 72, 74, 76, and 78 have the same configuration as side walls 32, 34, 36, and 38, respectively. Note that, in the vertical direction of packaging container 10, side walls 72, 74, 76, and 78 are shorter than side walls 32, 34, 36, and 38, respectively. Side wall 72 includes side plates 72a and 72b similar to side plates 32a and 32b, respectively. Note that side plates 72a and 72b are shorter than side plates 32a and 32b, respectively. Side wall 74 includes side plates 74a and 74b similar to side plates 34a and 34b, respectively. Note that side plates 74a and 74b are shorter than side plates 34a and 34b, respectively. The side wall 76 includes side plates 76a and 76b similar to the side plates 36a and 36b. Note that the side plates 76a and 76b are shorter than the side plates 36a and 36b, respectively. The side wall 78 includes side plates 78a and 78b similar to the side plates 38a and 38b, respectively. Note that the side plates 78a and 78b are shorter than the side plates 38a and 38b, respectively. The side walls 72, 74, 76, and 78 have similar shapes to one another.

[0053] A bent piece 86a similar to bent piece 46a is connected via a bend line to the edge of side plate 72b and side plate 78b facing the top plate 70. A bent piece 86b similar to bent piece 46b is connected via a bend line to the edge of side plate 74b and side plate 76b facing the top plate 70.

[0054] An extension piece 82a similar to extension piece 42a is connected via a bend line to the edge of side plate 72a opposite to side plate 62a. Extension piece 82a has an engagement notch on the edge opposite to side plate 72a. The engagement notch is located in the center of side plate 72a in the up-down direction of the packaging container 10. The dimensions of extension piece 82a differ from those of extension piece 42a to match the dimensions of the lid portion 60.

[0055] Similarly, an extension piece 84a similar to extension piece 44a is connected via a bend line to the edge of side plate 74a opposite to side plate 64a. An extension piece 84b similar to extension piece 44b is connected via a bend line to the edge of side plate 76a opposite to side plate 66a. An extension piece 82b similar to extension piece 42b is connected via a bend line to the edge of side plate 78a opposite to side plate 68a.

[0056] The side wall 66 is connected to the front edge of the top plate 70 via a fold line. The side wall 66 has a configuration similar to that of the side wall 26. The side wall 66 includes side plates 66a, 66b, a connecting piece 66c, and a folding piece 66d similar to the side plates 26a, 26b, the connecting piece 26c, and the folding piece 26d. The side wall 66 is shorter than the side wall 26 in the vertical direction of the packaging container 10. Therefore, the side plates 66a, 66b are shorter than the side plates 26a, 26b in the vertical direction of the packaging container 10. The side wall 68 is connected to the rear edge of the top plate 70 via a fold line. The side wall 68 has a configuration similar to that of the side wall 28. The side wall 68 includes side plates 68a, 68b, a connecting piece 68c, and a folding piece 68d similar to the side plates 28a, 28b, the connecting piece 28c, and the folding piece 28d. In the vertical direction of the packaging container 10, the side wall 68 is shorter than the side wall 28. Therefore, in the vertical direction of the packaging container 10, the side plates 68a, 68b are shorter than the side plates 28a, 28b.

[0057] The lid part 60 is produced from the deployable body BL2 in the same way as when the storage part 20 is produced from the deployable body BL1.

[0058] The lid portion 60 has the same effect as the storage portion 20. Because the storage portion 20 and the lid portion 60 are configured to be less likely to bend relative to each other, the strength of the packaging container 10 can be made relatively high. In addition, a packaging container 10 with high design quality can be produced. As with the edges 50, 52, the edges of the outer plates between the side walls 72, 74, 76, 78 and the side walls 66, 88 also face each other at an angle, improving the design quality.
