[0003] [Patent Document 1] JP 2011-105335 A Summary of the Invention [Problem to be solved by the invention]

[0004] In a packaging container, if an object to be packaged is stored therein and the object moves within the packaging container, the object may be damaged. In this specification, a technology is provided that can suppress the object from moving within the packaging container. [Means for solving the problem]

[0005] A first aspect of the technology disclosed in this specification relates to a packaging container. The packaging container may include a main body including a first side plate, a second side plate facing the first side plate with a gap therebetween, and a third side plate arranged to overlap a surface of the second side plate opposite to the first side plate, a first end plate extending from the first side plate toward the second side plate at a first end of the main body, and an upper end plate connected to an edge of the first side plate at a second end of the main body opposite to the first end via a folding line, the first side plate being inclined toward the second side plate in a direction away from the first end plate, and the upper end plate may be joined to the second side plate at the second end of the main body.

[0006] According to this configuration, by inclining the first side plate relative to the second side plate, the space in which the object moves can be reduced, and the movement of the object inside the packaging container can be suppressed. Also, by overlapping the third side plate with the second side plate, the packaging container can be reinforced.

[0007] In a second aspect of the technology disclosed in the present specification, in the first aspect, the packaging container may include a support portion extending from the third side plate at the first end. The support portion may extend from the first end toward the second end and support the first end plate from the first end side.

[0008] With this configuration, the first end plate can be supported by the support portion.

[0009] In a third aspect of the technology disclosed in this specification, in the second aspect described above, the first end plate may be inclined from the first side plate toward the second side plate, from the first end toward the second end of the main body located on the opposite side of the first end.

[0010] According to this configuration, the first end plate, which is disposed at an angle, can be supported by the support portion extending from the first end portion toward the second end portion, thereby making it possible to prevent the first end plate from shifting toward the first end portion.

[0011] In a fourth aspect of the technology disclosed in this specification, in the second or third aspect above, the support portion may include a support plate extending from an edge of the third side plate on the first end side toward the second end side along a surface of the second side plate on the first side plate side.

[0012] With this configuration, the first end plate can be supported by the support plate.

[0013] In a fifth aspect of the technology disclosed in this specification, in the fourth aspect above, the support plate may have a recess that receives a tip portion of the first end plate and extends beyond the first end plate toward the second end.

[0014] In this configuration, the first end plate is received in the recess of the support plate and engages with the support plate, allowing the support plate to properly support the first end plate. Also, in this configuration, the support plate is disposed between the second side plate and the first end plate at a position midway from the first end to the second end. This prevents the support plate from moving away from the second side plate and collapsing by the first end plate. With this configuration, it is possible to prevent the support plate from being released from its state of supporting the first end plate.

[0015] In a sixth aspect of the technology disclosed in this specification, in the fourth or fifth aspect above, the support portion may include a second end plate extending from the end of the support plate on the second end side toward the first side plate and overlapping with the first end plate.

[0016] According to this configuration, the second end plate can be disposed closer to the second end than the first end plate, thereby preventing an object such as a commodity in the packaging container from directly contacting the first end plate, thereby reducing the load applied to the first end plate.

[0017] In a seventh aspect of the technology disclosed in this specification, in any one of the first to sixth aspects above, the third side panel may be provided with a perforation that separates the support portion from the main body.

[0018] With this configuration, the support plate can be easily separated from the main body, and as a result, the support of the first end plate is released, allowing the packaging container to be opened.

[0019] A development body capable of assembling a packaging container of any one of the above first to seventh forms, which is made up of a single flat plate, is also novel and useful. [Brief description of the drawings]

[0021] (Embodiment) As shown in FIG. 1, the packaging container 10 packages the object 100 with the front side exposed. The packaging container 10 is used to transport the object 100 and display the object 100 in a storefront. The packaging container 10 can also be hung and displayed by inserting a hook or the like into a through-hole 10a disposed at the upper end of the packaging container 10. The use of the packaging container 10 is not limited to transportation and display, and it may also be used for protection, storage, and the like. The front-rear, left-right, and up-down directions included in this specification are defined for ease of explanation and do not necessarily define the posture during actual use.

[0022] As shown in Fig. 2, the packaging container 10 completely covers the object 100 on the back side. Also, as shown in Fig. 1 and Fig. 2, the packaging container 10 covers the left and right side surfaces of the object 100 on both the left and right sides. That is, the packaging container 10 contains the object 100 with the front portion of the object 100 exposed and the back and the left and right side surfaces covered.

[0023] The packaging container 10 comprises a main body 20 and a bottom 30 (see FIG. 3). The length of the main body 20 in the front-rear direction gradually decreases from the lower end to the upper end, and the main body 20 has a generally triangular shape in a side view. The bottom 30 is disposed at the lower end of the main body 20. The bottom 30 closes the lower end of the main body 20. Note that the bottom 30 does not have to completely close the lower end of the main body 20, and a portion of the lower end may be open.

[0024] As shown in FIG. 4, the packaging container 10 is produced by folding a plurality of fold lines provided on one flat plate-like development body BL. Each of the plurality of fold lines has a groove along the fold line so that the container can be easily folded along the fold line. The fold lines are represented by thin lines. The packaging container 10 is made of paper such as cardboard or thick paper. There is no limitation on the material of the packaging container 10, and it may be made of resin or metal, for example. In addition, a lattice-like thin line is provided in the area where the adhesive is applied.

[0025] The main body 20 includes a front panel 22, a rear panel 24, an outer panel 26, and an upper end panel 28. The front panel 22 includes a front portion 22a, a left portion 22b, a right portion 22c, and an upper end portion 22d. The front portion 22a is located at the center of the front of the packaging container 10. The front portion 22a has a rectangular flat plate shape. The front portion 22a is directly connected to the left portion 22b via a fold line 23b at its left end edge extending parallel to the vertical direction. The left portion 22b is folded at the fold line 23b so as to be inclined backward from the front portion 22a on the left side of the front of the packaging container 10. The upper end edge of the left portion 22b is inclined upward as it moves away from the front portion 22a in accordance with the shape of the upper end of the packaging container 10. The front portion 22a is directly connected to the right side portion 22c via a folding line 23c at its right edge extending parallel to the up-down direction. The right side portion 22c is disposed symmetrically with respect to the left side portion 22b.

[0026] The front side plate 22 has an opening 50 that straddles the front portion 22a, the left side portion 22b, and the right side portion 22c. The opening 50 is disposed in the center of the front side plate 22 in the left-right direction and in the middle position in the up-down direction. The length of the opening 50 in the left-right direction is longer than that of the front portion 22a. The opening 50 reaches both the left side portion 22b and the right side portion 22c.

[0027] The upper ends of the front portion 22a, the left side portion 22b, and the right side portion 22c are directly connected to the upper end portion 22d via the fold line 23d at the upper edges of the front portion 22a, the left side portion 22b, and the right side portion 22c. The upper end portion 22d is bent at the fold line 23d so as to be inclined backward from the front portion 22a at the upper end portion of the front surface of the packaging container 10. The upper end portion 22d is inclined backward at both left and right ends in accordance with the backward inclination of the left side portion 22b and the right side portion 22c.

[0028] The upper end plate 28 is directly connected to the front plate 22 at the upper end of the upper end 22d via a bend line 20c. The upper end plate 28 has an upper end 28a facing the upper end 22d, and a lower end 28b directly connected to the upper end 28d via a bend line 29a. The upper end 28a has a similar configuration to the upper end 22d. The upper end 28a faces the upper end 22d at a distance in the front-rear direction. The distance between the upper end 28a and the upper end 22d in the front-rear direction gradually increases from the upper end of the main body 20 downward. The lower end 28b is located at the lower end of the upper end 28a, and has a shape that follows the rear side plate 24 and the outer plate 26 described later.

[0029] The front plate 22 is directly connected to the rear plate 24 via a fold line 20a at its left edge extending parallel to the up-down direction. The rear plate 24 has a rear portion 24a, a left side portion 24b, and an upper end portion 24d. The rear portion 24a is located at the center of the back surface of the packaging container 10. The rear portion 24a faces the front portion 22a at a distance in the front-rear direction. The rear portion 24a has a rectangular flat plate shape similar to the front portion 22a. The right edge 24R of the rear portion 24a extends parallel to the up-down direction. The right edge 24R of the rear portion 24a is not connected to any other portion and is free.

[0030] The rear portion 24a is directly connected to the left portion 24b via a fold line 25b at its left edge extending parallel to the up-down direction. The left portion 24b is folded at the fold line 25b so as to incline forward from the rear portion 24a and disposed on the left side of the rear surface of the packaging container 10. The left portion 24b faces the left portion 22b at a distance in the front-rear direction. The left portion 24b is directly connected to the left portion 22b via the fold line 20a at the left and right ends of the main body 20. The upper edge of the left portion 24b, like the left portion 22b, is inclined upward as it moves away from the rear portion 24a in accordance with the shape of the upper end of the packaging container 10.

[0031] The upper ends of the rear portion 24a and the left side portion 24b are directly connected to the upper end portion 24d via the fold line 25d at the upper edge of the rear portion 24a and the left side portion 24b. The upper end portion 24d is arranged at the upper end portion of the back surface of the packaging container 10 by being folded so as to be inclined forward from the rear portion 24a at the fold line 25d. The upper end portion 24d is inclined forward at the left end portion in accordance with the inclination of the left side portion 24b. The upper end portion 24d is arranged overlapping the upper end portion 22d. The upper end portion 24d is folded into a shape that follows the portion that is arranged overlapping the upper end portion 22d.

[0032] The rear portion 24a has a through hole 52 at its lower end. The through hole 52 is disposed in the center of the rear portion 24a in the left-right direction. The through hole 52 is disposed below the lower end of the opening 50. The length of the through hole 52 in the up-down direction is longer than the plate thickness of the deployable body BL. In the left-right direction, the length of the lower end 52a of the through hole 52 is shorter than the upper end 52b.

[0033] The front plate 22 is directly connected to the outer plate 26 via a fold line 20b at its right edge extending parallel to the vertical direction. The outer plate 26 has a configuration that is approximately symmetrical to the rear plate 24. That is, the outer plate 26 has an outer rear portion 26a, a right side portion 26c, and an upper end portion 26d. The outer rear portion 26a is located at the center of the back surface of the packaging container 10, behind the rear portion 24a. The outer rear portion 26a is arranged overlapping the back surface of the rear portion 24a. The outer rear portion 26a has a rectangular flat plate shape similar to the rear portion 24a. The left edge 26L of the outer rear portion 26a extends parallel to the vertical direction. The left edge 26L of the outer rear portion 26a is not connected to other portions.

[0034] The outer rear portion 26a is directly connected to the right side portion 26c via a fold line 27c at the right edge extending parallel to the up-down direction. The right side portion 26c is folded at the fold line 27c so as to incline forward from the outer rear portion 26a on the right side of the rear surface of the packaging container 10. The right side portion 26c faces the right side portion 22c at a distance in the front-rear direction. The right side portion 26c is directly connected to the right side portion 22c at the left and right ends of the main body 20 via a fold line 20b. The upper edge of the right side portion 26c, like the left side portion 22b, is inclined upward as it moves away from the outer rear portion 26a in accordance with the shape of the upper end of the packaging container 10.

[0035] The upper ends of the outer rear portion 26a and the right side portion 26c are directly connected to the upper end portion 26d via the fold line 27d at the upper edge of the outer rear portion 26a and the right side portion 26c. The upper end portion 26d is bent at the fold line 27d so as to incline forward from the outer rear portion 26a at the upper end portion of the back surface of the packaging container 10. The upper end portion 26d is inclined forward at the right end portion in accordance with the inclination of the right side portion 26c. The upper end portion 26d is placed overlapping the upper end portion 22d. The upper end portion 26d is folded into a shape that conforms to the portion that is placed overlapping the upper end portion 22d.

[0036] (Bottom Configuration) The bottom portion 30 is disposed at the lower end of the main body 20. The bottom portion 30 includes a first bottom plate 32 and a support portion 34. The first bottom plate 32 is directly connected to the lower edge of the front portion 22a via a fold line 20d. The first bottom plate 32 has a shape that follows the lower end of the main body 20. The right edge 32a of the first bottom plate 32 is formed parallel to the front-rear direction. The length of the first bottom plate 32 in the direction perpendicular to the fold line 20d, i.e., the lower edge of the front portion 22a, is longer than the distance between the front portion 22a and the rear portion 24a at the lower end of the packaging container 10. The tip portion 32b located on the opposite side of the front portion 22a of the first bottom plate 32 is formed shorter than the other portion 32c in the left-right direction. In the left-right direction, the length of the tip portion 32b is shorter than the upper end portion 52b of the through hole 52 and is approximately the same as the lower end portion 52a. Specifically, the tip portion 32b gradually becomes thinner as it moves away from the portion 32c, and the left-right length of the end portion on the portion 32c side is slightly longer than the left-right length of the lower end portion 52a.

[0037] The support portion 34 includes a support plate 36 and a second bottom plate 38. The support plate 36 is directly connected to the lower edge of the outer rear portion 26a via fold lines 20e and 20f. The two fold lines 20e and 20f are parallel to the left-right direction and spaced apart from each other in the front-rear direction. The support plate 36 has a rectangular flat plate shape. In the left-right direction, the support plate 36 has the same length as the outer rear portion 26a. In the direction perpendicular to the fold line 20f, the distance from the fold line 20f to the edge of the support plate 36 opposite the outer rear portion 26a is shorter than the distance between the lower edge of the opening 50 and the lower edge of the front portion 22a.

[0038] A second bottom plate 38 is directly connected to the edge of the support plate 36 opposite the outer rear portion 26a via a fold line 37. The second bottom plate 38 has a shape that conforms to the lower end of the main body 20. The left edge 38a of the second bottom plate 38 is formed parallel to the front-rear direction. The length of the second bottom plate 38 in the direction perpendicular to the fold line 37, i.e., the edge of the support plate 36 opposite the outer rear portion 26a, is approximately the same as the distance between the front portion 22a and the rear portion 24a at the height at which the second bottom plate 38 is disposed in the packaging container 10.

[0039] The left edge 38a of the second bottom plate 38 is formed parallel to the front-rear direction. The left edge 38a is one of the left and right edges of the deployable body BL. By forming the left edge 38a in a straight line parallel to the front-rear direction, it is possible to easily position the deployable body BL along the guide.

[0040] A through hole 54 extending along the fold line 37 is disposed between the support plate 36 and the second bottom plate 38. The left-right length of the through hole 54 is the same as the left-right length of the upper end portion 52b of the through hole 52.

[0041] (Method of assembling packaging containers) Next, a method of assembling the packaging container 10 containing the object 100 from the developable body BL will be described. First, from the developable body BL, the upper end plate 28 is folded backward relative to the front plate 22 at the folding line 20c. Next, the rear plate 24 is folded backward relative to the front plate 22 at the folding line 20a. A part of the upper end of the rear plate 24 overlaps with the upper end plate 28 from the rear. The rear plate 24 and the upper end plate 28 are bonded together by adhesive in a bonding region 60 located on the upper end plate 28. Note that the upper end plate 28 and the rear plate 24 may be joined together by a method other than adhesive.

[0042] Next, the outer plate 26 is folded rearward relative to the front plate 22 at the folding line 20b. In the outer plate 26, the outer rear portion 26a overlaps the rear portion 24a from the rear. The rear plate 24 and the outer plate 26 are bonded together by the adhesive in the bonding area 62 located on the outer rear portion 26a. In this manner, the main body 20 is formed.

[0043] Next, the front plate 22, the rear plate 24, the outer plate 26, and the upper end plate 28 are folded at their respective folding lines, so that the front plate 22 and the rear plate 24 are separated from each other in the front-rear direction. As a result, the body 20 is deformed so that the gap between the front portion 22a and the rear portion 26b gradually widens from the upper end edge 20U toward the lower end edge 20L. The left side portions 22b and 24b are deformed so as to move away from each other around the folding line 20b as a rotation axis. Similarly, the right side portions 22c and 24c are deformed so as to move away from each other around the folding line 20c as a rotation axis. As a result, the lower end edge 20L of the body 20 opens in a substantially hexagonal shape, as shown in FIG. 5.

[0044] Next, the object 100 is accommodated in the main body 20. Next, the support plate 36 is folded upward at the folding lines 20e and 20f of the outer plate 26 so as to overlap the front surface of the rear portion 24a. With this configuration, since the two folding lines 20e and 20f are arranged, the support plate 36 can be folded neatly across the rear portion 24a. At this time, as shown in FIG. 6, the second bottom plate 38 is folded forward at the folding line 37 relative to the support plate 36. The second bottom plate 38 fits into the space surrounded by the front side plate 22 and the rear side plate 24. The second bottom plate 38 can prevent the front side plate 22 and the rear side plate 24 from moving in the direction of approaching each other. The second bottom plate 38 fits into the gap between the front side plate 22 and the rear side plate 24, thereby restricting the second bottom plate 38 from being displaced.

[0045] FIG. 7 is a cross-sectional view of the packaging container 10 at the center in the left-right direction. The through hole 54 is arranged to overlap with the through hole 52. The part of the through hole 54 that is formed on the second bottom plate 38 side of the folding line 37 is folded forward. Next, the first bottom plate 32 is folded backward with respect to the front plate 22 at the folding line 20d. The tip portion 32b passes through the through hole 54 and is received in the through hole 52. This completes the packaging container 10. The first bottom plate 32 is inclined upward from the front plate 22 to the rear plate 24. The upper end portion 52b of the through hole 52 is longer in the left-right direction than the tip portion 32b, so that the tip portion 32b can be easily inserted into the upper end portion 52b. On the other hand, the lower end portion 52a has substantially the same length as the tip portion 32b in the left-right direction, so that the tip portion 32b can be prevented from coming off the lower end portion 52a.

[0046] 7, in the first bottom plate 32, the tip portion 32b is inserted into the through-holes 52, 54, so that the tip portion 32b engages with the support plate 36 and the rear portion 24a. This allows the first bottom plate 32 to be appropriately supported by the support plate 36.

[0047] The support plate 36 is sandwiched between the first bottom plate 32 and the rear side plate 24. This makes it possible to prevent the support plate 36 from moving away from the rear side plate 24 and falling forward. Furthermore, since the tip portion 32b of the first bottom plate 32 penetrates the through-hole 54, it is possible to prevent the engagement between the first bottom plate 32 and the support plate 36 from being released.

[0048] The object 100 contained in the packaging container 10 is placed on the second bottom plate 38. This makes it possible to prevent the object 100 from being placed on the first bottom plate 32 and tilting, even if the first bottom plate 32 is disposed at an angle.

[0049] The packaging container 10 is inclined such that the front side plate 22 and the rear side plate 24 approach each other from the bottom to the top. This makes it possible to suppress the movement of the object 100 contained in the packaging container 10 within the packaging container 10. Since the packaging container 10 has a shape that conforms to the shape of the object 100, the movement of the object 100 can be further restricted. In addition, the packaging container 10 can be reinforced by overlapping the outer side plate 26 and the rear side plate 24. By joining the outer side plate 26 and the rear side plate 24 to the upper end plate 28, the side plate 26 and the rear side plate 24 can be positioned. This makes it possible to maintain the shape of the packaging container 10.

[0050] (How to open) A method for opening the packaging container 10 will be described with reference to Figures 2, 8, and 9. The outer panel 26 has a perforation 70 extending in an arc shape from the middle position of the left edge to the right side. The perforation 70 extends from the left edge of the outer rear portion 26a to the right side, crossing the fold line 20b, and reaching the right side portion 26c. The perforation 70 extends to the lower edge of the right side portion 26c.

[0051] A gripping piece 72 is disposed on the left edge of the outer rear portion 26a. The gripping piece 72 is located directly below the perforation 70 and protrudes leftward from the left edge of the outer rear portion 26a.

[0052] As shown in Fig. 8, when opening the packaging container 10, a user grasps the gripping piece 72 and moves the gripping piece 72 so as to break the perforation 70. When the perforation 70 is broken, the outer rear portion 26a is separated into an upper portion 74 that remains on the main body 20 side and a lower portion 76 that is cut off from the main body 20. The lower portion 76 is connected to the support portion 34 via fold lines 20e and 20f. As shown in Fig. 9, when the lower portion 76 is pulled away from the main body 20, the support portion 34 is pulled out from the lower edge 20L of the main body 20 together with the lower portion 76.

[0053] The tip portion 32b of the first bottom plate 32 is inserted into the through hole 54 of the support portion 34. In this configuration, when the support portion 34 is pulled out from the main body 20, the support portion 34 engages with the tip portion 32b, and the tip portion 32b is pushed downward. As a result, the first bottom plate 32 is pulled out from the main body 20 by rotating downward about the fold line 20d as a rotation axis. This causes the packaging container 10 to be opened, and the object 100 can be removed from the packaging container 10.

[0054] According to this configuration, the first bottom plate 32 can be pulled out from the main body 20 by breaking the perforation 70 and separating the lower portion 76 from the main body 20. As a result, in order to open the packaging container 10, it is only necessary to separate the lower portion 76 from the main body 20, and it is not necessary to directly operate the first bottom plate 32 to open it.

[0055] By forming the perforations 70 in an arc shape from the middle position of the outer rear portion 26a, the perforations 70 can be broken smoothly.

[0056] By making the packaging container 10 from paper, the number of plastic packaging containers used for displaying the object 100 can be reduced.

[0057] The opening 50 extends not only to the front portion 22a of the front plate 22 but also to the left and right side portions 22b, 22c. This allows the object 100 to be viewed from the left and right sides.

[0058] (Correspondence) The front side plate 22 is an example of a "first side plate", the rear side plate 24 is an example of a "second side plate", and the outer side plate 26 is an example of a "third side plate". The lower edge 20L is an example of a "first end portion", and the upper edge 20U is an example of a "second end portion". The first bottom plate 32 is an example of a "first end plate", and the second bottom plate 38 is an example of a "second end plate". The through hole 54 is an example of a "recess".

[0059] 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 changes of the specific examples exemplified above.

[0060] The length of the main body 20 of the packaging container 10 in the front-rear direction gradually decreases from the lower edge 20L to the upper edge 20U. However, the length of the main body 20 in the front-rear direction may be uniform from the lower edge 20L to the upper edge 20U, for example, like a cylinder or a square tube. Alternatively, the length in the front-rear direction may increase from the lower edge 20L to the upper edge 20U.

[0061] When the upper end of the main body 20 has a width in the front-rear direction, a configuration similar to the bottom part 30 may be disposed at the upper end. In this case, the bottom part of the main body 20 does not need to have the configuration of the bottom part 30.

[0062] There is no particular limitation on the shapes of the first bottom plate 32 and the second bottom plate 38. The first bottom plate 32 may be longer than the length of the lower end edge 20L of the main body 20 in the front-rear direction.

[0063] The support plate 36 may be disposed so as to be inclined forward with respect to the rear portion 24a. In this case, the support plate 36 may support the first bottom plate 32 from below at a middle position of the first bottom plate 32 in the front-rear direction.

[0064] The support plate 36 does not have to extend upward beyond the first bottom plate 32. In this case, the upper edge of the support plate 36 may abut against the first bottom plate 32, thereby causing the support plate 36 to support the first bottom plate 32 from below.

[0065] The rear portion 24a does not necessarily have to have the through hole 54. Instead of the through hole 52, the support plate 36 may have a recess for receiving the tip portion 32b of the first bottom plate 32.

[0066] The first bottom plate 32 does not have to be inclined from the front plate 22 toward the rear plate 24, and may be disposed parallel to the front-rear direction.

[0067] The support portion 34 may have a notch and a recessed groove for receiving the tip portion 32b, instead of the through hole 54. In this case, the second bottom plate 38 may not be disposed. The notch may be formed on the edge of the support plate 36 opposite the rear plate 26, facing the rear plate 26. The recessed groove is recessed in the plate thickness direction of the support portion 34, and does not have to penetrate through.

[0068] In addition, the technical elements described in this specification or drawings exert technical utility alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. In addition, the technologies exemplified in this specification or drawings achieve multiple objectives simultaneously, and achieving one of those objectives is itself technically useful.
