Description

[Technical Field]

[0001] The present specification discloses a packaging container and a deployment body. [Background technology]

[0002] Patent Document 1 discloses a storage box in which one side of the lid is supported by an end of the box body and which opens and closes vertically. The storage box has a configuration in which the bottom plate rises from the box body in response to opening and closing of the lid. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Jpn. Jpn. Appl. KOKAI Publication No. 61-172012 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above storage box, when the lid is open, the bottom plate is positioned at an upward incline relative to the box body. An object to be stored in the storage box is placed on the bottom plate. When the lid is open, a downward load acts from the object on the bottom plate. If the lid is not supported when it is open, the bottom plate will move downward, causing the lid to move in the direction of closing. In the above storage box, it is difficult to keep the lid open without supporting it.

[0005] This specification proposes a technology that allows a packaging container to be maintained in an open state. [Means for solving the problem]

[0006] A first aspect disclosed in this specification is a packaging container, the packaging container comprising: a base plate; a side wall portion standing upright from the base plate and surrounding the base plate with an open section; a side cover plate rotatably connected to the base plate via a first fold line; a main cover plate rotatably connected to the side cover plate via a second fold line; an end plate facing the base plate across the side wall portion at an end of the main cover plate opposite the side cover plate and covering a part of the base plate; and a support portion extending from the main cover plate beyond the side cover plate onto the base plate, the side cover plate being rotatable relative to the base plate; and an open position in which the main cover plate faces the base plate across the side wall portion in the closed position, and is located on the opposite side of the base plate across the side cover plate in the open position, and the support portion includes a cover side plate attached to the main cover plate, a connecting plate rotatably connected to the cover side plate via a third fold line, and a support plate rotatably connected to the connecting plate via a fourth fold line and disposed on the base plate, and when the main cover plate and the side cover plate move from the closed position to the open position, the support plate may move on the base surface toward the open section.

[0007] In this packaging container, when the main cover plate and the side cover plate are moved from the closed position to the open position while the support plate is supporting an object to be packaged, the support plate moves into the open section provided on the side wall portion. This moves the object supported by the support plate toward the open section. With this configuration, the object can be moved toward the open section without lifting the support plate away from the base plate. This prevents the support plate from moving toward the base plate due to the load received from the object. The main cover plate and the side cover plate can be prevented from moving from the open position toward the closed position in accordance with the movement of the support plate. As a result, the packaging container can be easily maintained in an open state.

[0008] A second aspect disclosed in the present specification is the above-mentioned first aspect, wherein in the open position, the third fold line may be positioned closer to the main cover plate and further away from the side cover plate than the second fold line.

[0009] This configuration prevents the third fold line from overlapping the second fold line when the main cover plate and the side cover plate are in the open position, allowing the main cover plate and the side cover plate to move smoothly between the closed position and the open position.

[0010] A third aspect disclosed in the present specification is the above-mentioned first or second aspect, wherein in the open position, the fourth fold line may be positioned closer to the main cover plate and farther away from the base plate than the first fold line.

[0011] This configuration prevents the fourth fold line from overlapping the first fold line when the main cover plate and the side cover plate are in the open position, allowing the main cover plate and the side cover plate to move smoothly between the closed position and the open position.

[0012] A fourth aspect disclosed in this specification may be any one of the first to third aspects, wherein the support plate comprises a main body portion extending from the connecting plate along the base plate, and an end piece portion connected to the edge of the main body portion opposite the connecting plate and extending along the side wall portion.

[0013] With this configuration, when the support plate is moved to the open section and the object placed on the main body moves, the end piece can support the object, thereby preventing the object from slipping off the support plate and being unable to move.

[0014] The fifth aspect disclosed in the present specification may be a deployment body that is made up of a single flat plate and that can be assembled into any one of the packaging containers of the first to fourth aspects. [Brief explanation of the drawings]

[Figure 6] 1 shows a longitudinal cross-sectional view of the packaging container with the lid in the closed position. [Figure 7] 1 shows a longitudinal cross-sectional view of the packaging container with the lid in an open position. DETAILED DESCRIPTION OF THE INVENTION

[0016] (Example) The packaging container 10 shown in Fig. 1 is a container for storing one or more objects X, such as food, daily necessities, etc. The packaging container 10 has a rectangular parallelepiped shape. In a modified example, the packaging container 10 may have another shape, such as a cube or a polygonal pillar. As shown in Fig. 2, the packaging container 10 exposes the object X stored in the packaging container 10 to the outside of the packaging container 10 by opening the lid portion 30.

[0017] 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.

[0018] (Configuration of the deployed packaging container) As shown in FIG. 3, the packaging container 10 is assembled by folding the unfoldable body BL, which is made of a single flat plate, along folding lines. In FIG. 3, adhesive areas where adhesive is applied 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 BL is made of thin corrugated cardboard. The material of the unfoldable body BL, i.e., the packaging container 10, is not limited to corrugated cardboard and may be, for example, cardboard, resin, etc.

[0019] The packaging container 10 comprises a base plate 12, a side wall portion 20, a lid portion 30, a support portion 40, and an end plate 50. The base plate 12 has a rectangular flat plate shape. The side wall portion 20 is connected to the base plate 12 via fold lines on the front edge and on both left and right side edges. The side wall portion 20 comprises three side plates 22, 24, and 26.

[0020] The side plate 22 is connected to the left edge of the base plate 12 via a bend line. The side plate 22 has a rectangular flat plate shape extending over the entire length of the base plate 12 in the front-to-rear direction. The side plate 24 is connected to the front edge of the base plate 12 via a bend line. The side plate 24 has a rectangular flat plate shape extending over the entire length of the base plate 12 in the left-to-right direction. The side plate 26 is disposed symmetrically with the side plate 22. The side plate 22 is connected to the right edge of the base plate 12 via a bend line. The side plate 26 has a rectangular flat plate shape extending over the entire length of the base plate 12 in the front-to-rear direction.

[0021] The lid portion 30 is connected to the rear edge of the base plate 12 via a fold line 90 on the rear edge. The lid portion 30 includes a side lid plate 32 and a main lid plate 34. The side lid plate 32 is connected to the base plate 12 via the fold line 90. The side lid plate 32 extends over the entire length of the base plate 12 in the left-right direction and has a rectangular flat plate shape that is slightly longer than the left-right length of the base plate 12. Both ends of the side lid plate 32 in the left-right direction slightly protrude from the left and right edges of the base plate 12. In the packaging container 10, the length of the side lid plate 32 in the up-down direction is longer than the lengths of the side plates 22, 24 by approximately the plate thickness of the deployable body BL.

[0022] The main cover plate 34 is connected to the side cover plate 32 via a fold line 92 at the end opposite the base plate 12, i.e., on the upper edge of the packaging container 10. The main cover plate 34 extends over the entire length of the side cover plate 32 in the left-right direction, and has a flat plate shape whose left-right length becomes shorter forward of the midpoint in the front-to-rear direction in the closed state. The left-to-right length of the front part of the main cover plate 34 is approximately equal to the left-to-right length of the base plate 12.

[0023] A support portion 40 is arranged on the edge of the main cover plate 34 opposite the side cover plate 32, i.e., the front edge of the packaging container 10, via a fold line 102 on the edge. The support portion 40 includes a cover side plate 42, a connecting plate 44, and a support plate 46. The cover side plate 42 is connected to the main cover plate 34 via the fold line 102. The cover side plate 42 has a flat plate shape that is shorter than the main cover plate 34 so that it does not protrude from the main cover plate 34 in the left-right direction when arranged overlapping the main cover plate 34. The cover side plate 42 is formed so that the length in the left-right direction is even shorter at the end opposite the main cover plate 34.

[0024] A connecting plate 44 is connected to the lid side plate 42 via a fold line 94 on the end opposite to the main lid plate 34, i.e., on the rear end edge of the packaging container 10. The connecting plate 44 extends over the entire length of the lid side plate 42 in the left-right direction, and has a flat plate shape whose left-right length increases as it moves away from the lid side plate 42. In the front-rear direction of the packaging container 10, the length of the connecting plate 44 is shorter than the length of the side lid plate 32.

[0025] The support plate 46 is connected to the connecting plate 44 via a fold line 96 on the end opposite the lid side plate 42, i.e., on the rear end edge of the packaging container 10. The support plate 46 has a flat plate shape that is shorter than the base plate 12 in the left-right direction and shorter than the base plate 12 in the front-rear direction of the packaging container 10.

[0026] (Configuration of support plate) A slit is formed in the center of the support plate 46. As a result, the support plate 46 comprises a main body portion 80 and an end piece portion 84. The main body portion 80 forms the outer peripheral edge of the support plate 46. In the main body portion 80, a base end piece 86 connects a pair of side pieces 88, 88 that extend from the connecting plate 44 in a direction away from the lid side plate 42 at the ends opposite the connecting plate 44.

[0027] An end piece portion 84 is connected to the base end piece 86 via a bend line. The end piece portion 84 includes two end pieces 84a and 84b that are connected to each other via a bend line. The end pieces 84a and 84b are disposed on the inner circumferential side of the main body portion 80.

[0028] An end panel 50 is connected via a fold line to the edge of the base panel 12 opposite the lid portion 30. At both left and right ends of the end panel 50, the length in the front-to-rear direction of the packaging container 10 is longer than at the center in the left and right direction. Insertion pieces 52, 54 are respectively arranged via fold lines at both left and right end edges of the end panel 50.

[0029] Flaps 62, 66 are respectively disposed along folding lines on the edges of the side plates 22, 26 opposite the base plate 12. An opening 72 for receiving the insert piece 52 is disposed between the side plate 22 and the flap 62. An opening 76 for receiving the insert piece 54 is disposed between the side plate 26 and the flap 66.

[0030] Insertion pieces 74, 78 are arranged on both left and right end edges of the cover side plate 42 via bending lines, and are inserted into the openings 72, 76 while overlapping with the insertion pieces 52, 54, respectively.

[0031] (Method of manufacturing packaging container) As shown in FIG. 4, when preparing the packaging container 10 from the unfolded body BL, the folding line 102 is folded and the lid side plate 42 is placed on the main lid plate 34. The main lid plate 34 and the lid side plate 42 are bonded to each other with adhesive applied to the bonding area (the area represented by the grid pattern in FIG. 3). Next, as shown in FIG. 5, the side plates 22, 24, and 26 of the side wall 20 are raised upward relative to the base plate 12. At the rear end of the side wall 20, the side wall 20 is not continuous between the side plate 22 and the side plate 26, forming an open section 20a that opens the storage space defined by the side wall 20 and the base plate 12. The open section 20a is located at the rear end of the base plate 12.

[0032] Next, the end plate 50 is bent relative to the side plate 24, and the end plate 50 is positioned opposite the base plate 12 with the side wall 20 sandwiched between them. At this time, the side wall 20 and the end plate 50 are positioned relative to the base plate 12 by inserting the insertion pieces 52, 54 into the openings 72, 76, respectively. The end plate 50 covers a portion of the front end of the base plate 12.

[0033] In the state shown in Fig. 5, an object X can be placed in the storage space of the packaging container 10. In this embodiment, a plurality of objects X are arranged side by side in the left-right direction, but the number of objects X to be placed in the packaging container 10 is not particularly limited. As shown in Figs. 6 and 7, when placing an object X, the end piece portion 84 of the support plate 46 is bent so that the boundary between the end piece 84a and the end piece 84b is recessed toward the object X. A part of the object X is inserted between the end piece 84a and the end piece 84b.

[0034] Next, as shown in FIG. 1 , the side cover plate 32 is bent upward relative to the base plate 12 at fold line 90, and the main cover plate 34 is bent forward relative to the side cover plate 32 at fold line 92. At this time, in the support portion 40, the connecting plate 44 is bent upward relative to the support plate 46 at fold line 96, and the side cover plate 42 is bent forward relative to the connecting plate 44 at fold line 94. By inserting the insertion pieces 74, 78 into the openings 72, 76, respectively, the cover portion 30 and the support portion 40 are positioned relative to the base plate 12. A portion of the front end of the main cover plate 34 overlaps with the end plate 50, thereby closing the packaging container 10. The main cover plate 34 faces the base plate 12 across the side wall portion 20 and covers a portion of the rear end of the base plate 12. The state shown in FIG. 1 is when the cover portion 30 is in the closed position.

[0035] Figure 6 shows a cross-sectional view of the center in the left-right direction when the lid part 30 shown in Figure 1 is in the closed position. The front end portion of the object X is stored in the packaging container 10 while being sandwiched between the end pieces 84a, 84b. The packaging container 10 is opened by moving the lid part 30 from the closed position to the open position as shown in Figure 2. The lid part 30 is rotated from the closed position so that the side lid plate 32 falls backward relative to the base plate 12 at the fold line 90, and the main lid plate 34 is rotated backward relative to the side lid plate 32 at the fold line 92.

[0036] As the lid portion 30 rotates, the support portion 40 moves rearward. Specifically, as the lid side plate 42 rotates rearward together with the main lid plate 34, the connecting plate 44 rotates relative to the lid side plate 42 and the support plate 46 at each of the fold lines 94, 96, and is thereby moved rearward while rotating rearward together with the lid side plate 42. As a result, as shown in FIG. 7 , the support plate 46 slides on the base plate 12 and is moved rearward from the open section 20a of the side wall portion 20 to the rear of the side wall portion 20. As a result, the object X is moved rearward from the side wall portion 20 along with the support plate 46 and exposed from the packaging container 10.

[0037] (effect) When the lid portion 30 is moved from the closed position to the open position, i.e., when the packaging container 10 is opened, the object X protrudes rearward from the side wall portion 20 of the packaging container 10. With this configuration, when a user opens the packaging container 10, the object X can be moved to a position where it is easily visible to the user. The object X can be moved from the open section 20a to the outside of the side wall portion 20 without lifting the support plate 46 upward from the base plate 12. This prevents the support plate 46 from moving toward the base plate 12 due to the load received from the object X. It also prevents the main cover plate 34 and the side cover plate 32 from moving together with the support plate 46 from the open position toward the closed position. As a result, the packaging container 10 can be maintained in an open state.

[0038] 7, when the cover 30 is in the open position, the fold lines 92 and 94 are offset from each other. By preventing the fold lines 92 and 94 from overlapping, the main cover plate 34 and the side cover plate 32 can be moved smoothly between the closed position and the open position via the fold line 92.

[0039] 7, when the cover 30 is in the open position, the fold lines 90 and 96 are offset from each other. By preventing the fold lines 90 and 96 from overlapping, the side cover plate 32 and the base plate 12 can be moved smoothly via the fold line 90.

[0040] The amount of movement of the support plate 46, i.e., the object X, in the front-to-back direction when the lid part 30 moves from the closed position to the open position increases as the sum of the length between the main lid plate 34 of the side lid plate 32 and the base plate 12 (i.e., the vertical length in the closed position) and the front-to-back distance between the fold line 92 and the fold line 94 in the open position increases. Therefore, even without changing the external dimensions of the packaging container 10, the amount of movement of the object X can be increased by shortening the lid side plate 42 and moving the position of the fold line 94 closer to the fold line 102.

[0041] The end piece portion 84 supports the object X, thereby preventing the object X from not being moved along with the support portion 40. In addition, the support piece 82 disposed between the side pieces 88, 88 in the support portion 40 moves the object X slightly upward, so that the object X can be moved so as to protrude more from the packaging container 10.

[0042] Since the packaging container 10 can be produced from one deployable body BL, the packaging container 10 can be produced without assembling a plurality of parts.

[0043] The surface of the main cover plate 34 exposed to the outside of the packaging container 10 and the surface of the lid side plate 42 exposed to the inside of the packaging container 10 are located on the same plane in the unfolded body BL. With this configuration, designs such as patterns and letters can be applied by printing once on the surface of the main cover plate 34 exposed to the outside of the packaging container 10 and the surface of the lid side plate 42 exposed to the inside of the packaging container 10. This improves the design of the packaging container 10.

[0044] Although the embodiments of the present invention 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 alterations of the specific examples exemplified above.

[0045] (1) The number of end pieces arranged in the end piece portion 84 is not particularly limited. For example, the end piece portion 84 may have one end piece instead of the multiple end pieces 84a, 84b. In this case, the end piece may be bent toward the opposite side of the base plate 12 via a bending line relative to the main body portion 80. Alternatively, the end piece portion 84 may have three or more end pieces and surround the end of the object X.

[0046] (2) The support plate 46 does not need to have the end piece portion 84. In this case, the support plate 46 may have a configuration that prevents the object X from shifting from the support plate 46. For example, the support plate 46 may have an adhesive region for adhering the object X, or may have clamping pieces that clamp the middle portion of the object X in the front-to-rear direction.

[0047] (3) Instead of the main body portion 80 and the end piece portion 84, the support plate 46 may include one or more connecting pieces extending from the connecting plate 44 toward the front end of the base plate 12 and one or more support pieces disposed at the front ends of the connecting pieces. Similar to the end piece portion 84, the support pieces may be engaged with the object X so as to move the object X together with the connecting pieces.

[0048] (4) Flaps may be connected to the rear edges of the side plates 22, 26. This prevents gaps from forming between the side plates 22, 26 and the side cover plate 32 when the lid portion 30 is in the closed position. In this case, a lid-side flap connected to the flap may be disposed on the side cover plate 32. The lid-side flap may be connected to the side cover plate 32 and the flaps of the side plates 22, 26 via folding lines. In this case, the lid-side flap and the flaps of the side plates 22, 26 may be arranged side by side behind the side plates 22, 26 when the lid portion 30 is in the open position, and may be folded along the folding line between the lid-side flap and the flaps of the side plates 22, 26 and folded inside the packaging container 10 when the lid portion 30 moves from the open position to the closed position. This configuration allows the lid-side flap and the flaps of the side plates 22, 26 to move in accordance with the opening and closing of the lid portion 30. In this configuration, the connecting plate 44 may have a shape that does not interfere with the lid-side flap and the flaps of the side plates 22 and 26.

[0049] (5) In the embodiment, the side cover plate 32 covers the entire open section 20a in the closed position. However, the side cover plate 32 may cover only a part of the open section 20a.

[0050] (6) The packaging container 10 may be produced by combining multiple deployed bodies. For example, the packaging container 10 may be produced by combining a first deployed body including the base plate 12, the side wall portions 20, the lid portion 30, and the end plates 50, with a second deployed body including the support portion 40. The lid side plates 42 of the second deployed body may be combined by being adhered to the main lid plate 34 of the first deployed body.

[0051] 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.
