Description

[Technical Field]

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

[0002] Patent Document 1 discloses a packaging container that packages an item to be packaged in an exposed state. The packaging container includes a holder that supports the item to be packaged. The holder grips or supports the item while adapting to its shape. The holder includes a substantially plate-shaped front portion and a substantially plate-shaped back portion that has a shape corresponding to the front portion. The front and back portions are arranged to face each other. The holder has a window formed in the front portion for introducing the item to be packaged into the holder.

[0003] The window frame is formed to correspond to the contour of the packaged item. Multiple flaps for gripping the packaged item are arranged on the window frame. The multiple flaps are flap-shaped pieces that contact the packaged item from multiple directions toward the center of the packaged item, and grip the packaged item using the resulting frictional force.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2019-077478 Summary of the Invention [Problem to be solved by the invention]

[0005] In the above technology, the packaged item is held in place by the frictional force between the packaged item and the multiple flaps. Therefore, for example, if the contact area between the packaged item and the multiple flaps is small, sufficient frictional force may not be generated between the multiple flaps and the packaged item, and the packaged item may move back and forth.

[0006] This specification provides a technology that can prevent packaged items from moving back and forth when the packaged items are exposed. [Means for solving the problem]

[0007] This specification discloses a packaging container of a first embodiment, which includes a back panel, a first side portion connected to the back panel via a first fold line extending in the vertical direction, a second side portion connected to the back panel via a second fold line extending in the vertical direction and spaced apart from the first fold line, and an end portion connected to the back panel via a fold line and located at one of the upper and lower ends of the first and second side portions, and the first side portion includes a first side panel extending forward from the first fold line and a first support portion extending from a position of the first side panel spaced apart from the back panel via a third fold line. and the second side portion includes a second side panel extending forward from the second fold line, and a second support portion extending from a position of the second side panel spaced apart from the back panel via a fourth fold line, and the first support portion includes a first support plate extending toward the second side panel via the third fold line, and a second support plate connected to an edge of the first support plate on the second side panel side via at least a fifth fold line, and the second support portion includes a third support plate extending toward the first side panel via the fourth fold line, and and a fourth support plate connected to the edge via at least a sixth fold line, wherein the first support portion has a first opening through which an item to be packaged is placed, the second support portion has a second opening through which the item to be packaged is placed, the first support plate is positioned in front of the item to be packaged placed in the first opening and restricts the item to be packaged from moving forward beyond the first support plate, the second support plate is positioned behind the item to be packaged placed in the first opening, and the third support plate is positioned in front of the item to be packaged placed in the second opening. and restricts the packaged item from moving forward beyond the third support plate, the fourth support plate is located behind the packaged item placed in the second opening, and the end portion comprises a main body extending from the back plate to the ends of the first support portion and the second support portion opposite the back plate, and an extension piece connected to the main body via a fold line and extending from the specific end toward the other of the upper ends and lower ends of the first support portion and the second support portion, and the extension piece may engage with each of the first side portion and the second side portion.

[0008] With this configuration, the forward movement of the packaged item is restricted by the first support plate and the third support plate. The back plate, the second support plate, and the fourth support plate are located behind the packaged item. This restricts the packaged item from moving backward. As a result, the packaged item can be restricted from moving forward and backward within the packaging container.

[0009] In a second form, in the above-mentioned first form, the extension piece may include a first insertion piece that is inserted into a first insertion hole that penetrates the first side portion and is placed within the packaging container, and a second insertion piece that is inserted into a second insertion hole that penetrates the second side portion and is placed within the packaging container.

[0010] With this configuration, the first insertion piece inserted into the first insertion hole engages with the first side portion, thereby preventing the first side portion from moving relative to the back plate. Similarly, the second insertion piece inserted into the second insertion hole engages with the second side portion, thereby preventing the second side portion from moving relative to the back plate.

[0011] In a third form, in the above-mentioned second form, the first insertion hole may be positioned at the boundary between the first side plate and the first support plate, the second insertion hole may be positioned at the boundary between the second side plate and the third support plate, and the extension piece may extend from the first insertion hole to the second insertion hole.

[0012] With this configuration, the first insertion hole can be located at the front end of the first side portion, which makes it easier to insert the first insertion piece into the first insertion hole. The same applies to the relationship between the second insertion hole and the second insertion piece.

[0013] In a fourth form, in any one of the first to third forms described above, the upper edges of the first and second side panels each have an upward inclined portion that slopes upward from the back panel toward the front, and a downward inclined portion that slopes downward from the back panel toward the front, forward of the upper inclined portion, the specific end is the upper end, and the main body may have an upper inclined plate that slopes upward from the back panel toward the front, along the upper edges of the first and second side panels, and a lower inclined plate that slopes downward from the back panel toward the front, forward of the upper inclined portion.

[0014] According to this configuration, the upper end of the packaging container can be formed to protrude upward, which makes it easier for the packaging container to attract attention when it is displayed.

[0015] In a fifth embodiment, the first side portion may include a first fixed piece fixed to the back plate so that the second support plate can rotate relative to the back plate before the packaged item is packaged, and the second side portion may include a second fixed piece fixed to the back plate so that the fourth support plate can rotate relative to the back plate before the packaged item is packaged.

[0016] This configuration can restrict the first and second side portions from moving relative to the back plate, making it easier to place the packaged item in the packaging container.

[0017] A packaging container of a sixth embodiment disclosed in the present specification comprises a back panel, a first side portion connected to the back panel via a first fold line extending in a vertical direction, a second side portion connected to the back panel via a second fold line extending in a vertical direction away from the first fold line, and an end portion connected to the back panel via a fold line and located at a specific end of one of the upper and lower ends of the first side portion and the second side portion, wherein the first side portion comprises a first side panel extending forward from the first fold line and a third side panel extending from a position of the first side panel away from the back panel. and a first support portion extending via a fold line, the second side portion comprising a second side panel extending forward from the second fold line, and a second support portion extending from a position of the second side panel spaced apart from the back panel via a fourth fold line, the first support portion comprising a first support plate extending towards the second side panel via the third fold line, and a second support plate connected to an edge of the first support plate on the second side panel side via at least a fifth fold line, the second support portion comprising a third support plate extending towards the first side panel via the fourth fold line, and a second support plate connected to an edge of the first support plate on the second side panel side via at least a fifth fold line. and a fourth support plate connected to the edge of the third support plate on the first side plate side via at least a sixth fold line, wherein the first support portion has a first opening in which an item to be packaged is placed, the second support portion has a second opening in which the item to be packaged is placed, the first support plate is positioned in front of the item to be packaged placed in the first opening and restricts the item to be packaged from moving forward beyond the first support plate, the second support plate is positioned behind the item to be packaged placed in the first opening, and the third support plate is positioned in front of the item to be packaged placed in the second opening. The fourth support plate is located in front of the packaged item placed in the second opening and restricts the packaged item from moving forward beyond the third support plate, the fourth support plate is located behind the packaged item placed in the second opening, the first side portion may have a first fixed piece fixed to the back plate so that the second support plate can rotate relative to the back plate in a state before the packaged item is packaged, and the second side portion may have a second fixed piece fixed to the back plate so that the fourth support plate can rotate relative to the back plate in a state before the packaged item is packaged.

[0018] With this configuration, the forward movement of the packaged item is restricted by the first support plate and the third support plate. The back plate, the second support plate, and the fourth support plate are located behind the packaged item. This restricts the packaged item from moving backward. As a result, the packaged item can be restricted from moving forward and backward within the packaging container.

[0019] A deployment body that can assemble a packaging container of any one of the first to sixth forms described above and that is made up of a single flat plate is also novel and useful. [Brief explanation of the drawings]

[Figure 9] FIG. 10 is a development view of a packaging container according to a second embodiment. [Figure 10] FIG. 10 is a diagram for explaining the assembly of the packaging container of the second embodiment. [Figure 11] FIG. 11 is a diagram illustrating the assembly of the packaging container of the second embodiment following FIG. 10. [Figure 12] FIG. 10 is a development view of a packaging container according to a modified example.

[0021] (First Example) As shown in Figures 1 and 2, the packaging container 10 packages the packaged item 100 in an exposed state. The packaging container 10 is used to transport the packaged item 100 and display the packaged item 100 in a store. The uses of the packaging container 10 are not limited to transportation and display, and it may also be used for protection, storage, etc. The front-to-back, left-to-right, and up-to-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 Figure 3, the packaging container 10 is produced by folding a single flat, unfoldable body BL1 along multiple fold lines. Each of the fold lines has at least one of a groove and a slit along the fold line to allow for easy folding along the fold line. The fold lines are represented by thin dashed lines. The slits are cuts that either do not have a gap penetrating the flat plate or have a small gap.

[0023] The packaging container 10 comprises a back panel 12, a pair of side sections 30, 40, an upper end section 20, and a lower end section 50. The back panel 12 has a rectangular flat plate shape. The side section 30 is connected to the back panel 12 via a fold line 14 that extends in the vertical direction at one right edge of the back panel 12. The side section 30 comprises a side panel 34, a folding piece 32, and a support section 31.

[0024] The side panel 34 is connected to the back panel 12 via a fold line 14. The upper edge 34a of the side panel 34 includes an upwardly inclined portion that slopes upward in a direction away from the right edge of the back panel 12, and a downwardly inclined portion that slopes downward from the center of the side panel 34 in a direction away from the back panel 12. The side panel 34 has an oval-shaped opening 34b in the center. A fold piece 32 is connected to the lower edge of the side panel 34 via a fold line.

[0025] The support portion 31 is connected to the edge of the side panel 34 opposite the back panel 12 via a fold line 35. The support portion 31 includes support plates 36 and 38. The support plate 36 is connected to the side panel 34 via a fold line 35. The upper edge 36a of the support plate 36 is inclined upward in a direction away from the side panel 34. The support plate 38 is connected to the edge of the support plate 36 opposite the side panel 34 via a fold line 37 extending in the vertical direction. The upper edge 38a of the support plate 38 is inclined downward in a direction away from the support plate 36. The support plate 38 has an insertion piece 39 in the vertical center of the edge opposite the support plate 36. The insertion piece 39 protrudes from the edge of the support plate 38 opposite the support plate 36. The edge of the support plate 38 opposite the support plate 36 is recessed toward the support plate 38 at the position where the insertion piece 39 is located. The insertion piece 39 has a maximum length in the up-down direction at a middle position in the direction away from the support plate 38 .

[0026] The support plates 36, 38 have openings 30a, 30b that straddle the fold line 37. The opening 30a has a shape that follows the outer shape of the left side portion when the packaged item 100 is placed in the packaging container 10. The opening 30b is located at the upper end of the support part 31 and has an elliptical shape.

[0027] Between the back panel 12 and the side panel 34, a slit 14a is arranged parallel to the fold line 14 in a direction slightly offset from the fold line 14 toward the back panel 12. The slit 14a is bent toward the fold line 14 at both ends in the vertical direction and extends to the fold line 14. In the vertical direction, the slit 14a is slightly shorter than the longest portion of the insertion piece 39 in the vertical direction and slightly longer than the end of the insertion piece 39 on the support plate 38 side.

[0028] Between the support part 31 and the side plate 34, two slits 35a and 35b are arranged parallel to the fold line 35 in a direction slightly offset from the fold line 35 toward the support plate 36. Each of the slits 35a and 35b is bent toward the fold line 35 at both ends in the up-down direction and extends to the fold line 35.

[0029] A side portion 40 is connected to the back panel 12 via a fold line 16 extending in the vertical direction at the edge of the back panel 12 opposite to the side portion 30. The side portion 40 has the same configuration as the side portion 30. That is, the side portion 40 includes a slit 16a, openings 40a, 40b, a support portion 41, a folding piece 42, a side panel 44, an upper edge 44a, an opening 44b, a folding line 45, slits 45a, 45b, a support plate 46, an upper edge 46a, a folding line 47, a support plate 48, an upper edge 48a, and an insert piece 49, similar to the respective portions 14a, 30a, 30b, 31, 32, 34, 34a, 34b, 35, 35a, 35b, 36, 36a, 37, 38, 38a, 39 of the side portion 30.

[0030] An upper end portion 20 is connected to the back panel 12 via a fold line 21 extending along the upper edge. The upper end portion 20 includes an extension piece 22, main panels 24 and 26, and a pair of insertion pieces 28 and 28. The main panel 26 is connected to the upper edge of the back panel 12 via the fold line 21. Both left and right end edges of the main panel 26 are inclined so that the length in the left and right direction gradually increases with increasing distance from the back panel 12. The main panel 26 is slightly larger than the back panel 12 in the left and right direction. Both left and right ends of the main panel 26 protrude outward from the back panel 12. The main panel 24 is connected to the edge of the main panel 26 opposite the back panel 12 via a fold line 25. The main panel 24 has the same length as the main panel 26 in the left and right direction. Both left and right edges of the main body plate 24 are inclined near the edge opposite the main body plate 26 so that the length in the left and right direction gradually decreases toward the edge opposite the main body plate 26.

[0031] The extension piece 22 is connected to the edge of the main body plate 24 opposite to the main body plate 26 via a fold line 23. The extension piece 22 has the same length as the back plate 12 in the left-right direction. The edge of the extension piece 22 opposite to the main body plate 24 is formed in an arc shape. A pair of insertion pieces 28, 28 are connected to each of the left-right ends of the extension piece 22 via a fold line. Each of the pair of insertion pieces 28, 28 is arranged so as to overlap the corresponding slit 35a, 45a when the packaging container 10 is assembled.

[0032] The lower end portion 50 is connected to the back panel 12 via a fold line 55 extending along the lower edge. The lower end portion 50 includes an extension piece 52, a main panel 54, and a pair of insertion pieces 58, 58. The main panel 54 is connected to the lower edge of the back panel 12 via the fold line 55. The main panel 54 has the same length as the back panel 12 in the left-right direction. The left and right ends of the main panel 54 are located on the same straight line as the left and right end edges of the back panel 12. The extension piece 52 is connected to the edge of the main panel 54 opposite the back panel 12 via a fold line 53. The extension piece 52 has the same length as the back panel 12 in the left-right direction. The edge of the extension piece 52 opposite the main panel 54 is formed in an arc shape. The pair of insertion pieces 58, 58 are connected to the left and right ends of the extension piece 52 via fold lines. The pair of insert pieces 58, 58 are arranged so as to overlap the slits 35b, 45b, respectively, when the packaging container 10 is assembled.

[0033] (Method of assembling the packaging container 10) Next, a method for assembling the packaging container 10 from the unfolded body BL1 will be described with reference to FIGS. 3 to 6. First, the side portion 40 shown in FIG. 4 is assembled from the unfolded body BL1 shown in FIG. 3. Specifically, the side panel 44 is bent along the fold line 16 so as to be positioned in front of the back panel 12. The support panel 46 is bent along the fold line 45 so as to be positioned from the side panel 44 to the right side of the packaging container 10. The support panel 48 is then bent along the fold line 47 so as to bend from the support panel 46 toward the back panel 12. The insertion piece 49 is inserted into the slit 16a. Because the back panel 12 and the side panel 44 are bent along the fold line 16, the slit 16a opens by a length offset from the fold line 16. This allows the insertion piece 49 to be inserted into the opening formed by the slit 16a. A portion of the insertion piece 49 is formed longer in the vertical direction than the slit 16a. As a result, when the insertion piece 49 is inserted into the opening formed by the slit 16a, the insertion piece 49 can be prevented from easily falling out of the opening formed by the slit 16a.

[0034] As shown in FIG. 5, the side portion 30 is similarly folded along fold line 35 so that the support plate 36 is positioned from the side plate 34 to the left side of the packaging container 10. Furthermore, the support plate 38 is folded along fold line 37 so that it is positioned from the support plate 36 toward the back plate 12. The insertion piece 39 is inserted into the slit 14a. When folding along fold line 14 so that the side plate 34 is positioned in front of the back plate 12, the packaged item 100 is positioned between the openings 30a and 40a. As a result, as shown in FIG. 6, the packaged item 100 is supported by the support portions 31 and 41 while positioned between the openings 30a and 40a. In the state shown in FIG. 6, the support plate 36 extends from the front edge of the side plate 34 toward the side plate 44 while sloping backward, and the support plate 38 extends from the boundary with the support plate 36 toward the side plate 34 while sloping backward. The rear edge of the support plate 38 is located at the corner between the back panel 12 and the side panel 34. Similarly, the support plate 46 extends from the front edge of the side panel 44 while sloping rearward toward the side panel 34, and the support plate 48 extends from the boundary with the support plate 46 toward the side panel 44 while sloping rearward. The rear edge of the support plate 48 is located at the corner between the back panel 12 and the side panel 44.

[0035] Next, from the state shown in FIG. 6 , the upper end 20 and the lower end 50 are folded forward relative to the back panel 12 to complete the packaging container 10 shown in FIG. 1 . At the upper end 20, the main panel 24 and the main panel 26 are folded at the fold line 25 along the upper edge 34a of the side panel 34 and the upper edge 44a of the side panel 44. The lower edge of the main panel 24 is positioned at the front ends of the side panels 34, 44. The extension piece 22 is folded downward at the fold line 23 relative to the main panel 24, along the front edges of the side panels 34, 44. Each of the pair of insertion pieces 28, 28 is inserted into the opening formed by the slits 35a, 45a by folding the fold lines 35, 45. When inserted into the opening formed by the slits 35a, 45a, each of the insertion pieces 28, 28 engages with the support panels 36, 46, respectively, from inside the packaging container 10. This prevents the upper end portion 20 from coming off the side portions 30, 40, and also prevents the side portions 30, 40 from rotating around the folding lines 14, 16, respectively, relative to the back panel 12. Since the slits 35a, 45a are located at the front ends of the side panels 34, 44, the insertion pieces 28, 28 can be easily inserted into the openings formed by the slits 35a, 45a.

[0036] At the upper end 20, the openings 24a, 26a are arranged at positions overlapping each other in the front-to-rear direction. Furthermore, the opening 30b of the side portion 30 is formed in a substantially semicircular shape by bending the support plates 36, 38 at the fold line 37, and the opening 40b of the side portion 40 is formed in a substantially semicircular shape by bending the support plates 46, 48 at the fold line 47, and these opposing openings form substantially circular openings arranged at positions overlapping the openings 24a, 26a. As a result, the packaging container 10 penetrates in the front-to-rear direction at the positions where the openings 24a, 26a and the openings 30b, 40b overlap. This allows the packaging container 10 to be hung and displayed by inserting a rod-shaped hook or the like for display at the positions where the openings 24a, 26a and the openings 30b, 40b overlap.

[0037] Similar to the upper end portion 20, the lower end portion 50 has a main plate 54 that is positioned perpendicular to the back plate 12 along the lower edges of the side plates 34 and 44. The folded pieces 32 and 42 of the side portions 30 and 40 are folded to overlap above the main plate 54. The front edge of the main plate 54 is positioned at the front ends of the side plates 34 and 44. The extension piece 52 is folded upward at a folding line 53 relative to the main plate 54 along the front edges of the side plates 34 and 44. Each of the pair of insertion pieces 58 is inserted into an opening formed by the slits 35b and 45b when the folding lines 35 and 45 are folded. When inserted into the opening formed by the slits 35b and 45b, each of the insertion pieces 58 engages with the support plates 36 and 46, respectively, from the inside of the packaging container 10. This prevents the lower end portion 50 from coming off the side portions 30, 40, and also prevents the side portions 30, 40 from rotating around the folding lines 14, 16, respectively, relative to the back panel 12. Since the slits 35b, 45b are located at the front ends of the side panels 34, 44, the insertion pieces 58, 58 can be easily inserted into the openings formed by the slits 35b, 45b.

[0038] The above description of the method does not limit the order of assembly. For example, the side portion 30 may be assembled first instead of the side portion 40. The lower end portion 50 may be folded first instead of the upper end portion 20.

[0039] (effect) As shown in Figure 1, in the packaging container 10, support plates 36, 46 are arranged in front of the packaged item 100, and support plates 38, 48 are arranged behind the packaged item 100. The packaged item 100 is restricted from moving forward by abutting against the support plates 36, 46, and restricted from moving rearward by abutting against the support plates 38, 48. This prevents the packaged item 100 from moving forward or backward. The support plates 38, 48 are restricted from moving rearward because the packaged item 100, whose forward movement is restricted by the support plates 36, 46, is arranged in front of it.

[0040] Additionally, the thickness of the packaged item 100 gradually increases in the front-to-back direction from both left-to-right ends toward the center. Support plates 36, 38 sandwich the packaged item 100 from the front and back to the right of the center of the packaged item 100 in the left-to-right direction. This prevents the packaged item 100 from shifting to the right. Similarly, support plates 46, 48 sandwich the packaged item 100 from the front and back to the left of the center of the packaged item 100 in the left-to-right direction. This prevents the packaged item 100 from shifting to the left. Furthermore, support plates 36, 38, 46, 48 can also prevent the packaged item 100 from shifting up and down.

[0041] Furthermore, by forming the shape of the openings 30a, 40a to follow the contour of the packaged item 100, it is possible to package packaged items 100 of various shapes. In particular, for a shape where the center is thicker than the left and right ends, by sandwiching the relatively thinner parts between the support parts 31, 41, it is possible to restrict movement of the packaged item in the front-to-back and left-to-right directions.

[0042] The openings 34b, 44b arranged in the side panels 34, 44 respectively allow the packaged item 100 to be viewed from both the left and right sides.

[0043] The upper edges 34a of the side panels 34 are inclined upward from the back panel 12 toward the front, and downward from the center in the front-to-rear direction toward the front. At the upper end 20, the main panel 24 is inclined upward toward the front along the upper edges 34a, and the main panel 26 is inclined downward toward the front along the upper edges 34a. By forming the upper end shape of the packaging container 10 to protrude upward, it can attract the attention of people visiting a store or the like when it is on display.

[0045] (Second Example) A packaging container 210 of a second embodiment will be described with reference to Figures 7 to 11. As shown in Figures 7 and 8, the packaging container 210, like the packaging container 10, packages the packaged item 200 in an exposed state.

[0046] As shown in Fig. 9, the packaging container 210 is produced by folding a single flat, deployable body BL2 along multiple fold lines. Each of the fold lines has at least one of a groove and a slit along the fold line to allow for easy folding along the fold line. The fold lines are represented by thin dashed lines.

[0047] The packaging container 210 includes a back panel 212, a pair of side sections 230 and 240, an upper end section 220, and a lower end section 250. The back panel 212 has the same configuration as the back panel 12, except that it does not have slits similar to slits 14a and 16a. The side section 230 is connected to the back panel 212 via a fold line 214 that extends in the vertical direction at the right edge. The side section 230 includes a side panel 234, folding pieces 232a and 232b, a support section 231, and an adhesive piece 239.

[0048] The side plate 234 is connected to the back plate 212 via a bending line 214. The side plate 234 has a rectangular flat plate shape. The upper and lower edges of the side plate 234 extend vertically in the up-down direction. The upper and lower edges of the side plate 234 are not inclined in the up-down direction. The side plate 234 has an opening 234b in the center. A bending piece 232a is connected to the lower edge of the side plate 234 via a bending line, and a bending piece 232b is connected to the upper edge of the side plate 234 via a bending line.

[0049] A support portion 231 is connected to the edge of the side plate 234 opposite the back plate 212 via a fold line 235. The support portion 231 includes support plates 236 and 238. The support plate 236 is connected to the side plate 234 via a fold line 235. The support plate 236 has a rectangular flat plate shape. The support plate 238 is connected to the edge of the support plate 236 opposite the side plate 234 via a fold line 237 extending in the vertical direction. The support plate 238 has a rectangular flat plate shape. In the vertical direction, the support plate 238 is slightly shorter than the support plate 236.

[0050] An adhesive strip 239 is connected to the edge of the support plate 238 opposite the support plate 236 via a fold line 239a. The adhesive strip 239 is connected over the entire length of the support plate 238 in the vertical direction. The fold line 239a is discontinued at a midpoint in the vertical direction. The adhesive strip 239 has a portion that extends beyond the fold line 239a to the support plate 238 side. An adhesive is applied to the adhesive strip 239. The area where the adhesive is applied has thin lines in a lattice pattern. No adhesive is applied to the portion of the adhesive strip 239 that extends beyond the fold line 239a to the support plate 238 side.

[0051] The support plates 236, 238 have an opening 230a that straddles the fold line 237. The opening 230a has a shape that follows the outer shape of the left side portion when the packaged item 200 is placed in the packaging container 210.

[0052] Between the support portion 231 and the side plate 234, two slits 235a and 235b are arranged parallel to the bending line 235, similar to the slits 35a and 35b, in a direction slightly shifted from the bending line 235 toward the support plate 236.

[0053] The side portion 240 is connected to the back panel 212 via a fold line 216 extending in the vertical direction at the edge of the back panel 212 opposite the side portion 230. The side portion 240 has the same configuration as the side portion 230. That is, like the respective portions 230a, 231, 232a, 232b, 234, 234b, 235, 235a, 235b, 236, 237, 238, 239, and 239a of the side portion 230, the side portion 240 includes an opening 240a, a support portion 241, insertion pieces 242a and 242b, a support plate 244, an opening 244b, a fold line 245, slits 245a and 245b, a support plate 246, a fold line 247, a support plate 248, an adhesive piece 249, and a fold line 249a.

[0054] An upper end portion 220 is connected to the back panel 212 via a fold line 221 extending along the upper edge. The upper end portion 220 includes an extension piece 222, a main panel 224, and a pair of insertion pieces 228, 228. The main panel 224 is connected to the upper edge of the back panel 212 via the fold line 221. The main panel 224 has the same length as the back panel 212 in the left-right direction. The main panel 224 has a rectangular flat plate shape. The extension piece 222 is connected to the edge of the main panel 224 opposite the back panel 212 via a fold line 223. The extension piece 222 has the same length as the back panel 212 in the left-right direction. The edge of the extension piece 222 opposite the main panel 224 is formed in an arc shape. A pair of insertion pieces 228, 228 are connected via folding lines to both ends in the left and right direction of the extension piece 222. Each of the pair of insertion pieces 228, 228 is arranged so as to overlap with each of the slits 235a, 245a when the packaging container 210 is assembled.

[0055] A lower end portion 250 is connected to the back panel 212 via a fold line 255 extending along the lower edge. The lower end portion 250 includes an extension piece 252, a main panel 254, and a pair of insertion pieces 258, 258. The main panel 254 is connected to the lower edge of the back panel 212 via the fold line 255. The main panel 254 has the same length as the back panel 212 in the left-right direction. The left and right ends of the main panel 254 are located on the same straight lines as the left and right end edges of the back panel 212. The extension piece 252 is connected to the edge of the main panel 254 opposite the back panel 212 via a fold line 253. The extension piece 252 has the same length as the back panel 212 in the left-right direction. At the edge of the main panel 252 opposite the main panel 254, a portion of the left end has an arc-shaped bulge. A pair of insertion pieces 258, 258 are connected via folding lines to both ends in the left-right direction of the main body plate 252. Each of the pair of insertion pieces 258, 258 is arranged so as to overlap with each of the slits 235b, 245b when the packaging container 210 is assembled.

[0056] (Method of assembling the packaging container 210) Next, a method of assembling the packaging container 210 from the unfolded body BL2 will be described with reference to Figures 9 to 11. First, as shown in Figure 10, the unfolded body BL2 shown in Figure 9 is folded along the folding line 235 between the side plate 234 and the supporting portion 231 so that the supporting portion 231 overlaps the side plate 234. As a result, the adhesive piece 239 overlaps the back plate 212. The adhesive piece 239 is adhered to the center in the left-right direction of the back plate 212. Similarly, the folding line 245 between the side plate 244 and the supporting portion 241 is folded along the folding line 245 between the side plate 244 and the supporting portion 241 so that the supporting portion 241 overlaps the side plate 244, and the adhesive piece 249 is adhered to the center in the left-right direction of the back plate 212. The adhesive pieces 239, 249 are adhered to the back plate 212 so that the edge of the adhesive piece 239 opposite the support plate 238 and the edge of the adhesive piece 249 opposite the support plate 248 face each other.

[0057] In a modified example, adhesive piece 239 and adhesive piece 249 may overlap and be adhered to back plate 212. This modified example is useful when producing a packaging container that is short in the left-right direction.

[0058] Next, as shown in Fig. 11, the side panels 234, 244 are folded forward relative to the back panel 212, and the packaged items 200 are placed in the openings 230a, 240a. In the state shown in Fig. 11, the support panel 236 extends from the front edge of the side panel 234 toward the side panel 244 while sloping backward, and the support panel 238 extends from the boundary with the support panel 236 toward the side panel 234 while sloping backward. The rear edge of the support panel 238 is located at the edge (i.e., the fold line 239a) of the adhesive strip 239 fixed to the back panel 212. Similarly, the support panel 246 extends from the front edge of the side panel 244 toward the side panel 234 while sloping backward, and the support panel 248 extends from the boundary with the support panel 246 toward the side panel 244 while sloping backward. The rear edge of the support plate 248 is located at the edge of the adhesive piece 249 fixed to the back plate 212 (ie, the bending line 249 a ).

[0059] Next, from the state shown in FIG. 11 , the upper end 220 and the lower end 250 are folded forward relative to the back panel 12 to complete the packaging container 210 shown in FIG. 7 . At the upper end 220, the main panel 224 is arranged perpendicular to the back panel 212 along the upper edges of the side panels 234 and 244. The folded pieces 232b of the side panels 230 and 242b of the side panels 240 are folded so as to overlap below the main panel 224. The front edge of the main panel 224 is arranged at the front ends of the side panels 234 and 244. The extension piece 222 is folded downward relative to the main panel 224 along the front edges of the side panels 234 and 244. Each of the pair of insertion pieces 228 and 228 is inserted into an opening formed by the slits 235a and 45a when the folding lines 235 and 245 are folded. When the insert pieces 228, 228 are inserted into the openings formed by the slits 235a, 245a, they engage with the support plates 236, 246, respectively, from the inside of the packaging container 210. This prevents the upper end portion 220 from coming off the side portions 230, 240, and also prevents the side portions 230, 240 from rotating around the folding lines 214, 216, respectively, relative to the back plate 212. Because the slits 235a, 245a are located at the front ends of the side plates 234, 244, the insert pieces 228, 228 can be easily inserted into the openings formed by the slits 235a, 245a.

[0060] Similarly, at the lower end portion 250, a main plate 254 is disposed perpendicular to the back plate 212 along the upper edges of the side plates 234 and 244. The bent piece 232a of the side portion 230 and the inserted piece 242a of the side portion 240 are folded to overlap above the main plate 244. The front edge of the main plate 254 is disposed at the front ends of the side plates 234 and 244. The extension piece 252 is folded upward relative to the main plate 254 along the front edges of the side plates 234 and 244. Each of the pair of inserted pieces 258 and 258 is inserted into an opening formed by the slits 235b and 245b formed by the folding lines 235 and 245 being folded. When the insert pieces 258, 258 are inserted into the openings formed by the slits 235b, 245b, they engage with the support plates 236, 246, respectively, from the inside of the packaging container 210. This prevents the upper end portion 250 from coming off the side portions 230, 240, and also prevents the side portions 230, 240 from rotating around the folding lines 214, 216, respectively, relative to the back plate 212. Because the slits 235b, 245b are located at the front ends of the side plates 234, 244, the insert pieces 258, 258 can be easily inserted into the openings formed by the slits 235b, 245b.

[0061] (effect) The packaging container 210 can appropriately support the packaged item 200, similar to the packaging container 10. Furthermore, the openings 234a, 244a arranged in the side plates 234, 244, respectively, allow the packaged item 200 to be viewed from both the left and right sides.

[0062] Each of the side portions 230, 240 is adhered to the back plate 212 by adhesive pieces 239, 249, respectively. With this configuration, when assembling the packaging container 210, it is possible to restrict the side portions 230, 240 from freely rotating relative to the back plate 212. This makes it possible to easily store the packaged item 200 in the packaging container 210.

[0063] (Correspondence) The adhesive piece 239 is an example of a "first fixing piece," and the adhesive piece 249 is an example of a "second fixing piece."

[0064] 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.

[0065] In the packaging container 10, the side portions 30 and 40 are arranged symmetrically. However, the configurations of the side portions 30 and 40 may not be arranged symmetrically and may have different configurations. The same applies to the packaging container 210.

[0066] The packaging container 10 may not have one of the end plates at the upper end 20 and the lower end 50. The same applies to the packaging container 210.

[0067] 12 , side portions 230, 240 of packaging container 210 may be replaced with side portions 330, 340. That is, the upper ends of side portions 330, 340 may have an upwardly protruding shape similar to side portions 30, 40. Upper end portion 220 may be replaced with upper end portion 320 similar to upper end portion 20. The remaining configurations of back panel 312, lower end portion 350, and side portions 330, 340 may be similar to those of back panel 212, lower end portion 250, and side portions 230, 240, respectively.

[0068] The insertion holes into which the insertion pieces 28, 28, 58, 58 are inserted do not have to be located at the front edges of the side plates 34, 44 of the side portions 30, 40. For example, they may be located on a flat portion behind the front edges of the side plates 34, 44, or on the support plates 36, 46. In this case, the insertion pieces 28, 28, 58, 58 may be located at positions corresponding to the insertion holes. The same applies to the packaging container 210.

[0069] The upper end portion 20 does not necessarily have to have the insert pieces 28, 28, 58, 58. For example, the upper end portion 20 may have a cylindrical shape that surrounds the outside of the side portions 30, 40. The upper end portion 20 may be fitted over the upper end portions of the side portions 30, 40 and engage with each of the side portions 30, 40 from the outside of the side portions 30, 40. The same applies to the lower end portion 50. The same applies to the packaging container 210.

[0070] In the packaging container 210, the back plate 212 may extend above the upper end portion 220. In this case, a through-hole may be provided in a portion of the back plate 212 that is located above the upper end portion 220. This allows the packaging container 210 to be hung on a hook or the like for display.

[0071] At least one of the upper end portion 220 and the lower end portion 250 may be connected to at least one of the side portions 230, 240 via a fold line. In this case, at least one of the upper end portion 220 and the lower end portion 250 does not have to be connected to the back panel 212 via a fold line.

[0072] In the packaging container 10, the packaged item 100 may be restricted from moving backward by contacting the back plate 12. In this case, the openings 30a, 40a may be adjusted in shape so that the packaged item 100 contacts the back plate 12. The packaged item 100 may or may not contact the support plates 38, 48. The same applies to the packaging container 210.

[0073] 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.
