Description

[Technical Field]

[0001] This specification discloses techniques relating to a packaging container and a deployable body. [Background technology]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2024-15650 Summary of the Invention [Problem to be solved by the invention]

[0004] For example, packaging containers used for gifts and other purposes that contain packaged items may be required to have an aesthetically pleasing appearance.

[0005] The present specification provides a technology that can improve the design of packaging containers.

[0006] A first aspect disclosed in this specification relates to a packaging container. The packaging container may include a bottom, a cylindrical sidewall surrounding the bottom, and a lid covering a storage space defined by the bottom and the sidewall, wherein the sidewall has a first edge extending in an axial direction of the cylindrical shape, a first adhesive strip extending from the first edge toward the inside of the cylindrical shape, a second edge extending in the axial direction of the cylindrical shape, and a second adhesive strip extending from the first edge toward the inside of the cylindrical shape, the second adhesive strip being adhered to the first adhesive strip and to an inner surface of the sidewall.

[0007] In this configuration, a first adhesive piece and a second adhesive piece are arranged to connect the first and second edges of the side wall portion. With this configuration, by arranging both the first adhesive piece and the second adhesive piece inside the cylindrical shape, it is possible to prevent the adhesive pieces of the side wall portion from being exposed to the outside of the side wall portion. Furthermore, because the first edge is connected to the first adhesive piece, it is possible to prevent the first edge from being exposed to the outside of the packaging container as an end surface, i.e., a cut surface. The same is true for the second edge. This can improve the design of the packaging container's appearance.

[0008] A second aspect disclosed in the present specification is the first aspect, wherein the second adhesive piece is sandwiched between the first adhesive piece and the inner surface of the side wall portion, and the first adhesive piece may be longer than the second adhesive piece in a direction perpendicular to the axial direction of the cylindrical member.

[0009] With this configuration, the second adhesive piece sandwiched between the first adhesive piece and the inner surface of the side wall portion can be covered by the first adhesive piece. This prevents the second adhesive piece from being exposed when the inside of the packaging container is viewed. This can improve the design of the inside of the packaging container.

[0010] A third aspect disclosed in this specification is that, in the first or second aspect above, the lid portion may comprise an outer cover plate and an inner cover plate connected to the outer cover plate via a fold line and overlapping and adhered to the surface of the outer cover plate facing the storage space.

[0011] This configuration increases the strength of the lid and prevents warping of the lid. It also prevents the edge of the outer lid plate from being exposed to the outside of the packaging container as an edge surface, thereby improving the design.

[0012] A fourth aspect disclosed in the present specification is any one of the first to third aspects, wherein the end faces of the side wall portion and the lid portion may not be exposed.

[0013] This configuration can improve the design of the appearance of the packaging container.

[0014] The deployable body for producing the above-mentioned packaging container, which is made up of a single flat plate, is also novel and useful. [Brief explanation of the drawings]

[0015] [Figure 1] FIG. 1 is a perspective view of a packaging container according to an embodiment. [Figure 2] FIG. 2 is a plan view of the unfolded packaging container of the embodiment. [Figure 3] FIG. 2 is an enlarged perspective view of the vicinity of the upper end of the packaging container of the embodiment in an open state. DETAILED DESCRIPTION OF THE INVENTION

[0016] (Example) As shown in Fig. 1, the packaging container 10 accommodates a packaged item 100 (see Fig. 3) such as a bottle. The packaging container 10 is used for transporting, storing, displaying, etc. the packaged item 100.

[0017] In this embodiment, the up-down direction, the front-rear direction, and the left-right direction are each defined as shown in Fig. 1. The up-down direction, the front-rear 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.

[0018] The packaging container 10 includes a bottom 12 (see FIG. 2), side walls 14, a lid 16, and a support 18. The packaging container 10 accommodates an item 100 to be packaged in a storage space 50 (see FIG. 3) defined by the bottom 12, side walls 14, and lid 16.

[0019] As shown in FIG. 2, the packaging container 10 is assembled by folding a single sheet of a deployed body BL made of corrugated cardboard along the fold lines. The packaging container 10 may be made of cardboard, cardboard, resin, or the like, and there is no limit to the material. FIG. 2 shows the surface located on the outside of the packaging container 10. In FIG. 2, the fold lines are drawn with thin dashed lines. Grooves are formed in the fold lines to make folding easier. In a modified example, the fold lines may not have grooves, as with other parts. The area where adhesive is applied is hatched. If the surface where adhesive is applied is a surface located on the outside of the packaging container 10, it is marked with parallel oblique lines, and if the surface where adhesive is applied is a surface located on the inside of the packaging container 10 (i.e., the back surface in FIG. 2), it is marked with grid lines.

[0020] The unfolded body BL forms the bottom 12, side wall 14, and lid 16 of the packaging container 10. The bottom 12 includes four bottom plates 22, 24, 26, and 28. The bottom 12 is formed by engaging the four bottom plates 22, 24, 26, and 28 with one another.

[0021] Side plates 32, 34, 36, 38 are connected to the four bottom plates 22, 24, 26, 28 via bending lines, respectively. The side plates 32, 34, 36, 38 are raised upward from the bottom plates 22, 24, 26, 28, respectively. In addition to the side plates 32, 34, 36, 38, the side wall portion 14 includes adhesive pieces 42, 44.

[0022] The side plates 32, 34, 36, and 38 each have a rectangular flat plate shape. In the deployable body BL, the side plates 32, 34, 36, and 38 are arranged adjacent to each other in this order. The side plates 32, 34, 36, and 38 are connected to the adjacent side plates 32, 34, 36, and 38 via bending lines, respectively.

[0023] An adhesive strip 42 is connected to an edge 52 of the side panel 32 opposite the side panel 34 via a fold line on the edge 52. The adhesive strip 42 is arranged along the entire length of the edge 52 of the side panel 32. An adhesive strip 44 is connected to an edge 54 of the side panel 38 opposite the side panel 36 via a fold line on the edge 54. The adhesive strip 44 is arranged along the entire length of the edge 54 of the side panel 38.

[0024] As shown in Figure 3, when assembling the packaging container 10, the fold lines located between the side panels 32, 34, 36, and 38 are folded to form the tubular side wall portion 14, and the adhesive strips 42 and 44 are folded inward of the tubular shape. The adhesive strip 44 is folded at the edge 54 so as to overlap the inner surface 38a of the side panel 38. The adhesive strip 44 is adhered to the inner surface 38a. The adhesive strip 42 is adhered to the surface of the adhesive strip 44 opposite the inner surface 38a.

[0025] In the adhesive piece 42, the length from the edge 52 to the end opposite the edge 52, i.e., the length perpendicular to the axial direction of the side wall 14, is longer than the length from the edge 54 to the end opposite the edge 54 in the adhesive piece 44. Specifically, the difference in length between the edge 52 and the edge 54 may be two to three times the thickness of the deployable body BL. As a result, the adhesive piece 44 is entirely covered by the adhesive piece 42. The adhesive piece 44 is hardly exposed from the storage space 50 inside the side wall 14. This improves the design of the packaging container 10 when viewed from the storage space 50 side.

[0026] Once the side walls 14 are assembled, each of the bottom plates 22, 24, 26, 28 is bent at a right angle to the side plates 32, 34, 36, 38. The bottom 12 is formed by engaging the bottom plates 22, 24, 26, 28 with one another.

[0027] As shown in Fig. 2, the support part 18 is connected to the upper edge of the side plate 32 via a folding line. The support part 18 has a through hole 62 through which the packaged item 100 is inserted. As shown in Fig. 3, the support part 18 is bent toward the storage space 50 with respect to the side plate 32. The support part 18 is positioned relative to the side wall part 14 by fitting into the side wall part 14. The packaged item 100 is stored in the storage space 50 while inserted into the through hole 62. This makes it possible to prevent the packaged item 100 from moving within the packaging container 10.

[0028] The lid portion 16 is connected to the upper edge of the side plate 36 via a fold line. The lid portion 16 includes an outer lid plate 72, inner lid plates 74 and 76, and an insert piece 78. The outer lid plate 72 is connected to the upper edge of the side plate 36 via a fold line. The outer lid plate 72 has a rectangular flat plate shape that covers the upper opening of the side wall portion 14. The inner lid plates 74 and 76 are connected to the left and right sides of the outer lid plate 72 via fold lines, respectively. As shown in FIG. 3 , the inner lid plate 74 is folded back relative to the outer lid plate 72 and bonded to the surface of the outer lid plate 72 facing the storage space 50. Similar to the inner lid plate 74, the inner lid plate 76 is folded back relative to the outer lid plate 72 and bonded to the surface of the outer lid plate 72 facing the storage space 50.

[0029] This prevents the left and right edges of the outer cover plate 72 from being exposed to the outside as end faces, i.e., cut faces. This improves the design of the exterior of the packaging container 10. Furthermore, by overlapping the inner cover plates 74, 76 on the outer cover plate 72, the strength of the lid portion 16 can be improved. The outer cover plate 72 is made of thin corrugated cardboard, and is prone to warping and bulging upward if the inner cover plates 74, 76 are not placed. By overlapping the inner cover plates 74, 76 on the outer cover plate 72, warping of the outer cover plate 72 can be prevented.

[0030] An insert piece 78 is connected via a fold line to the end of the outer cover plate 72 opposite the side plate 36, i.e., the front end. When the cover 16 is closed, the insert piece 78 is bent inwardly into the side wall 14 and inserted along the inner surface of the side plate 32 facing the side plate 36. This prevents the front edge of the outer cover plate 72 from being exposed to the outside as an end face, thereby improving the design of the appearance of the packaging container 10.

[0031] Flaps 82, 84 are connected via folding lines to the upper ends of the side plates 34, 38, respectively. When the lid 16 is closed, the flaps 82, 84 are folded relative to the side plates 34, 38, respectively, before the lid 16 is folded so as to be positioned above the storage space 50. When the lid 16 is closed, the flaps 82, 84 come into contact with the insertion piece 78, thereby preventing the lid 16 from being opened.

[0032] In the packaging container 10, adhesive strips 42, 44 are connected to the edges 52, 54 of the side wall portion 14 via folding lines, respectively. The adhesive strips 42, 44 are folded toward the inside of the packaging container 10. This prevents the edges 52, 54 from being exposed to the outside of the packaging container 10 as end faces. This improves the design quality of the appearance of the packaging container 10.

[0033] When the lid 16 of the packaging container 10 is closed, none of the end faces of the packaging container 10 are exposed to the outside except for the bottom 12. This allows the design of the appearance of the packaging container 10 to be improved.

[0034] The support portion 18 is connected to the upper edge of the side plate 32 via a folding line. The support portion 18 is folded toward the inside of the packaging container 10. This prevents the upper edge of the side plate 32 from being exposed as an edge surface to the outside of the packaging container 10. Similarly, the flaps 82, 84 are connected to the upper edges of the side plates 34, 38 via folding lines. The flaps 82, 84 are folded toward the inside of the packaging container 10. This prevents the upper edges of the side plates 34, 38 from being exposed as an edge surface to the outside of the packaging container 10. These configurations enable the design of the appearance of the packaging container 10 to be improved.

[0035] (Correspondence) Edge 52 is an example of a "first edge," and edge 54 is an example of a "second edge." Adhesive piece 42 is an example of a "first adhesive piece," and adhesive piece 44 is an example of a "second adhesive piece."

[0036] Although specific examples of the present invention have been described above in detail, these are merely examples and do not limit the scope of the claims. The technology described in the claims includes various modifications and alterations of the specific examples exemplified above.

[0037] The shape of the side wall 14 is not particularly limited. For example, the side wall 14 may have any cylindrical shape, such as a polygonal cylindrical shape other than a rectangular cylindrical shape, a cylindrical shape, or an elliptical cylindrical shape. When the side wall 14 is formed by continuous side plates, the adhesive pieces on both end edges may be folded toward the inside of the packaging container 10 and adhered to each other, similar to the adhesive pieces 42, 44. The shapes of the bottom 12 and the lid 16 may be appropriately formed to match the shape of the side wall 14.

[0038] In the deployable body BL, the side plates 32, 34, 36, and 38 do not have to be adjacent to each other via a folding line. For example, in the deployable body BL, the side plates 32 and 34 may be spaced apart from each other. In this case, adhesive pieces similar to the adhesive pieces 42 and 44 may be disposed on the edges of the side plates 32 and 34, respectively. This prevents the edges of the side plates 32 and 34 from being exposed to the outside as edge surfaces.

[0039] Furthermore, the technical elements described in this specification or drawings may exhibit technical utility either alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. Furthermore, the technologies illustrated in this specification or drawings simultaneously achieve multiple objectives, and achieving one of those objectives is itself technically useful.
