[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-186039 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above technology, an object is placed inside the top panel with the top panel open, and the top panel is closed by inserting multiple locking tabs connected to the top panel into locking slits. The above technology is intended to be used in two states: an open state and a closed state. This specification provides a technology that can be used in a packaging container in a novel state. [Means for solving the problem]

[0005] A first aspect of the technology disclosed in this specification relates to a packaging container comprising: a bottom plate; a side wall extending from the bottom plate; a flap extending from the side wall and facing the bottom plate across the side wall; a lid connected to the bottom plate on the opposite side of the bottom plate from the flap; an insert connected to the lid; and an opening penetrating the flap through which the insert is inserted, the lid being movable relative to the bottom plate between a closed position where the lid covers a storage space defined by the side wall and the bottom plate and overlaps with the flap, and an open position where the lid opens the storage space, and a state where the lid is in the open position and the storage space is open, and a state where the lid is in the closed position and a gap communicating with the storage space is formed between the lid and the flap at a position away from an edge of the flap on the side wall side in a direction in which the flap extends. and a second closed state in which the lid portion is disposed in the closed position and at least a portion of the gap between the lid portion and the flap is blocked, the insert piece having an insertion connecting portion connected to the lid portion via a first fold line and an insertion main body portion connected to the insertion connecting portion on the opposite side of the lid portion via a second fold line, and in the second closed state, the insertion main body portion is inserted into the opening and at least a portion of the gap between the lid portion and the flap is blocked by the insert piece, the length of the insertion main body portion in a direction perpendicular to the insertion direction of the insert piece into the opening is shorter than the length of the insertion connecting portion, and the insertion connecting portion may have a third fold line extending in a direction perpendicular to the insertion direction at an intermediate position in the insertion direction of the insert piece into the opening.

[0006] In the above-described packaging container, in the first closed state, a thin object such as paper can be stored in the storage space through a gap between the lid and the flap that communicates with the storage space. This configuration allows the packaging container to be used in the first closed state in addition to the open state and the second closed state. The gap between the lid and the flap is formed at a position away from the edge of the flap on the side wall side in the direction in which the flap extends. This configuration allows the object to be inserted into the storage space through the gap by aligning the object with the flap, making it easier to insert the object into the gap.

[0007] A second aspect of the technology disclosed in this specification is the first aspect described above, wherein the opening may be curved toward the insertion piece side.

[0008] According to this configuration, the insertion piece can be prevented from coming out of the opening while it is inserted in the opening. Also, since the opening is curved, it is easy to insert the insertion body into the opening.

[0009] A third aspect of the technology disclosed in this specification relates to a deployment body. The deployment body may be made of a single flat plate, and may be capable of assembling the packaging container according to the first or second aspect. [Brief explanation of the drawings]

[Figure 6] FIG. 10 is a perspective view illustrating how an object is stored in the first closed state. [Figure 7] 1 is a perspective view of a packaging container in the process of being assembled from a first closed state to a second closed state. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0011] (Example) As shown in FIG. 1, the packaging container 100 has a rectangular parallelepiped shape. The packaging container 100 may have other shapes, such as a cube. The packaging container 100 is used to package, transport, and store objects to be stored therein. In this embodiment, as shown in FIG. 1, the up-down direction, the front-rear direction, and the left-right direction are each indicated. These up-down direction, the front-rear direction, and the left-right direction are used to facilitate the explanation of this embodiment, and do not indicate the directions in which the packaging container 100 should be used.

[0012] As shown in FIG. 2, the packaging container 100 is produced by assembling the unfoldable body 102. The unfoldable body 102 is a single sheet of flat corrugated cardboard. The unfoldable body 102 is not limited to corrugated cardboard, and may be made of, for example, flat cardboard, resin, etc. Also, in FIG. 2, fold lines are indicated by thin dashed lines. Grooves are formed in the corrugated cardboard at the locations corresponding to the fold lines to make it easier to fold than other parts. Slits may be appropriately arranged in the fold lines. The slits are cuts that penetrate the flat plate and have small or no gaps.

[0013] The packaging container 100 has a bottom plate 10, four side plates 12, 14, 16, and 18, a lid 20, an insert piece 22, flaps 30, 32, and 34, folding pieces 42, 44, 46, and 48, and engaging pieces 50, 52, 54, and 56. Unless otherwise noted, the following description will be given using the directions of the packaging container 100 in a state in which the lid 20 is closed after the deployable body 102 has been assembled (i.e., the state shown in FIG. 1).

[0014] The bottom plate 10 has a rectangular flat plate shape. Side plates 12, 14, 16, and 18 are connected to the four edges of the bottom plate 10 via folding lines. The side plates 12, 14, 16, and 18 each have a rectangular flat plate shape. A folding piece 42 is connected to the front end of the side plate 12 via a folding line. A folding piece 46 is connected to the rear end of the side plate 12 via a folding line. A flap 32 is connected to the upper end of the side plate 12 via a folding line. Engagement holes 70 and 72 are disposed at the corners between the side plate 12 and the flap 32. The engagement holes 70 and 72 are formed by slits in the deployable body 102. When the flap 32 is folded from the deployable body 102 toward the side plate 12, the slits open and the engagement holes 70 and 72 open.

[0015] The side plate 16 is disposed on the opposite side of the side plate 12 across the bottom plate 10. The side plate 16, the bent pieces 44, 48, the flap 34, the engagement holes 74 and 76 each have the same configuration as the side plate 12, the bent pieces 42, 46, the flap 32, the engagement holes 70 and 72, respectively.

[0016] A side plate 18 is connected to the front end of the bottom plate 10. A flap 30 is connected to the upper end of the side plate 18 via a folding line.

[0017] The flap 30 has a flap main body 30a and flap protrusions 30b and 30c. The flap main body 30a is generally rectangular. The flap main body 30a has an opening 60 penetrating the flap main body 30a. The opening 60 has a shape that curves toward the rear. The flap 30 has slits that extend rearward from both the left and right ends of the opening 60.

[0018] The flap protrusion 30b extends rearward from the right side of the flap main body 30a at the rear end of the flap main body 30a. The left-right width of the flap protrusion 30b is shorter than half the left-right width of the flap main body 30a. An engagement piece 50 is connected to the right end of the flap protrusion 30b via a fold line. The length of the engagement piece 50 in the front-rear direction is approximately equal to the length of the engagement hole 72. The flap protrusion 30c extends rearward from the left side of the flap main body 30a at the rear end of the flap main body 30a. The left-right width of the flap protrusion 30c is shorter than half the left-right width of the flap main body 30a. As a result, the flap protrusions 30b, 30c are arranged spaced apart from each other. An engagement piece 52 is connected to the left end of the flap protrusion 30c via a fold line. In the front-rear direction, the length of the engagement piece 52 is approximately equal to the length of the engagement hole 76 .

[0019] The side plate 14 is connected to the rear end of the bottom plate 10. The lid portion 20 is connected to the upper end of the side plate 14 via a bending line. In other words, the lid portion 20 is connected to the bottom plate 10 on the opposite side of the bottom plate 10 from the flap 30.

[0020] The lid portion 20 has a rectangular flat plate shape. The length of the lid portion 20 in the front-rear direction is shorter than the length of the bottom plate 10 in the front-rear direction. The length of the lid portion 20 in the left-right direction is approximately equal to the length of the bottom plate 10 in the left-right direction. Furthermore, in the packaging container 100, the front edge of the lid portion 20 is positioned so as to overlap with the flap main body portion 30a and is positioned further rearward than the front edge of the flap main body portion 30a (i.e., the edge 64 on the side plate 18 side). An engagement piece 54 is connected to the right end of the lid portion 20 via a fold line. In the front-rear direction, the length of the engagement piece 54 is approximately equal to the length of the engagement hole 70. An engagement piece 56 is connected to the left end of the lid portion 20 via a fold line. In the front-rear direction, the length of the engagement piece 56 is approximately equal to the length of the engagement hole 74.

[0021] The insert piece 22 is connected to the front end of the lid portion 20 via a fold line. The insert piece 22 has an insert connecting portion 22a and an insert main body portion 22b. The insert connecting portion 22a is connected to the lid portion 20 at its rear end via a fold line 80. The fold line 80 is located behind the frontmost edge of the lid portion 20. The insert connecting portion 22a is separated from the lid portion 20 by slits at both left and right end edges. A fold line 82 extending in the left-right direction is provided at the center position of the insert connecting portion 22a in the front-to-rear direction. In a modified example, the fold line 82 may be located forward or rearward of the center of the insert connecting portion 22a in the front-to-rear direction. The fold line 82 may be located at an intermediate position excluding the front and rear ends of the insert connecting portion 22a in the front-to-rear direction.

[0022] The insertion body portion 22b is connected to the front end of the insertion connecting portion 22a via a fold line 84. The left-right length of the insertion body portion 22b is shorter than the left-right length of the insertion connecting portion 22a. The left-right length of the rear end of the insertion body portion 22b is approximately equal to the left-right length of the opening 60. The fold line 84 is located forward of the front edge of the lid portion 20.

[0023] (Method of assembling the packaging container 100 from the deployable body 102) As shown in Figure 3, the side plates 12, 16, and 18 are folded up from the deployable body 102 relative to the bottom plate 10. The folding pieces 42 and 44 are folded relative to the side plates 12 and 16, respectively, and positioned along the inner surface of the side plate 18. In addition, the flaps 32 and 34 are folded relative to the side plates 12 and 16, respectively, and positioned so as to face the bottom plate 10.

[0024] Next, the engagement pieces 50, 52 are bent downward and inserted into the engagement holes 72, 76, respectively. As a result, the engagement pieces 50, 52 engage with the flaps 32, 34, respectively. As a result, the flap 30 is positioned relative to the side plates 12, 16, 18.

[0025] As shown in Figure 4, the side panels 12, 16, 18, the flaps 30, 32, 34, and the bottom panel 10 form a space in which items can be stored (hereinafter referred to as the storage space). The lid 20 does not cover the storage space. Therefore, the user can place items in the storage space. The state shown in Figure 4 is the open state.

[0026] Next, from the open state, the side panel 14 is bent and raised relative to the bottom panel 10. The folding pieces 46, 48 are bent relative to the side panels 12, 16, respectively, and positioned along the inner surface of the side panel 14. The lid portion 20 is also bent relative to the side panel 14. Furthermore, the engagement pieces 54, 56 are bent downward, and the engagement pieces 54, 56 are inserted into the engagement holes 70, 74, respectively. As a result, the engagement pieces 54, 56 engage with the flaps 32, 34, respectively. This positions the lid portion 20 relative to the side panels 12, 14, 16. At this time, the lid portion 20 covers the storage space and is positioned so as to overlap the flaps 30, 32, 34.

[0027] In the state shown in Figure 5, the gap between the lid portion 20 and the flap 30 is not closed. In other words, a gap 62 that leads to the storage space is formed between the lid portion 20 and the flap 30. This state is the first closed state. In the first closed state, as shown in Figure 6, it is possible to insert an object into the storage space through the gap 62 between the lid portion 20 and the flap 30.

[0028] Next, from the first closed state, as shown in FIG. 7 , the insert piece 22 is bent along the fold line 80 to move the insert piece 22 upward relative to the lid portion 20. The insert connecting portion 22a is also bent along the fold line 82 to make a valley fold. At the fold line 84, the insert main body portion 22b is bent downward relative to the insert connecting portion 22a and inserted into the opening 60. This causes the insert main body portion 22b to engage with the flap 30. As a result, a portion of the gap 62 between the lid portion 20 and the flap 30 is closed. As a result, as shown in FIG. 1 , the packaging container 100 transitions to a second closed state in which the lid portion 20 covers the storage space and a portion of the gap 62 between the lid portion 20 and the flap 30 is closed. In the second closed state, the gap 62 between the lid portion 20 and the flap 30 is partially closed, preventing the object from falling out of the storage space.

[0029] In the first closed state, the front edge of the lid portion 20 is positioned away from the edge 64 of the flap main body portion 30a on the side panel 18 side. Therefore, when inserting an object into the storage space through the gap 62 between the lid portion 20 and the flap 30, the object can be inserted into the storage space along the flap main body portion 30a. With this configuration, it is easy to insert the object into the storage space through the gap 62.

[0030] Furthermore, in the first closed state described above, the lid portion 20 covers the storage space, and a gap 62 is provided between the lid portion 20 and the flap 30. In the first closed state, if an object is placed in the storage space, the object placed in the storage space is prevented from being exposed from the storage space, and a new object can be inserted into the storage space.

[0031] In the first closed state, the insertion piece 22 is positioned on the flap 30. The insertion piece 22 does not protrude forward beyond the side plate 18. This makes it less likely that the insertion piece 22 will get in the way when carrying the packaging container 100 in the first state, and prevents the insertion piece 22 from being damaged.

[0032] In the above-described embodiment, the length of the insertion connecting portion 22a in the left-right direction is longer than the length of the insertion main body portion 22b in the left-right direction. Therefore, when inserting the insertion main body portion 22b into the opening 60, the user can easily grasp how far to insert the insertion main body portion 22b. Furthermore, the insertion connecting portion 22a abuts against the flap 30, thereby preventing the insertion piece 22 from being inserted beyond the insertion main body portion 22b into the opening 60.

[0033] In the above-described embodiment, the insertion connecting portion 22a can be bent at the bending line 82. Therefore, when inserting the insertion body portion 22b into the opening 60, the insertion body portion 22b can be easily aligned with the opening 60. As a result, the insertion piece 22 can be easily inserted into the opening 60. Furthermore, since the opening 60 is curved, the insertion body portion 22b can be easily inserted into the opening 60.

[0034] In the above-described embodiment, when the insertion body portion 22b is inserted into the opening 60, the insertion body portion 22b comes into contact with both front and rear edges of the opening 60. This makes it possible to prevent the insertion body portion 22b from slipping out of the opening 60.

[0035] The side panels 12, 14, 16, and 18 are an example of a "side wall." The fold line 80 is an example of a "first fold line." The fold line 84 is an example of a "second fold line." The fold line 82 is an example of a "third fold line."

[0036] The bottom plate 10, the side plates 12, 14, 16, 18, and the lid portion 20 do not have to be flat. At least one of the bottom plate 10, the side plates 12, 14, 16, 18, and the lid portion 20 may be curved or may not have a uniform thickness.

[0037] The insert 22 may be disposed in the flap 30. In this case, the opening 60 may be disposed in the lid portion 20.

[0038] In the second closed state, the gap 62 may be closed by a configuration other than the insertion piece 22. For example, a plurality of insertion pieces may be connected to the lid portion 20. The plurality of insertion pieces may be arranged at intervals from one another in the left-right direction. The flap 30 may have openings into which the plurality of insertion pieces are inserted. Alternatively, for example, the lid portion 20 and the flap 30 may be provided with a pair of engaging pieces that engage with each other. Furthermore, for example, a protrusion that protrudes toward the other may be provided on either the lid portion 20 or the flap 30, and a fitting hole into which the protrusion fits may be provided on the other either the lid portion 20 or the flap 30.

[0039] The shape of the insertion piece 22 is not limited to the above. The insertion piece 22 may have a constant length in the left-right direction in the front-rear direction. Alternatively, for example, the insertion connecting portion 22a may have multiple bend lines extending in the left-right direction.

[0040] Although the embodiments have been described in detail above, these are merely examples and do not limit the scope of the claims. The technology described in the claims includes various modifications and variations of the specific examples exemplified above. The technical elements described in this specification or drawings exhibit technical utility alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. Furthermore, the technology exemplified in this specification or drawings simultaneously achieves multiple objectives, and achieving one of these objectives itself has technical utility.
