[0007] In the packaging container, an object is stored in the gap between the first main side plate and the second main side plate. The object is held in place by being pinched by the holding pieces. With this configuration, the position of the stored T-shirt is maintained by the holding pieces within the packaging container. Therefore, the object is prevented from being stored unevenly within the packaging container.

[0008] A second aspect disclosed in the present specification is the above-mentioned first aspect, wherein the holding piece may hold the object by sandwiching it between the first main side plate and the holding piece together with the first main side plate.

[0009] According to this configuration, the object can be held by the holding piece and the first main side plate.

[0010] A third aspect disclosed in this specification is that in the first or second aspect, the holding piece may hold the object by arranging it around the holding piece from the first main side plate side to the second main side plate side.

[0011] When an object is to be stored in a packaging container, the object may be folded. With this configuration, the holding piece can function as a guide when folding the object.

[0012] A fourth aspect disclosed in the present specification is any one of the first to third aspects, wherein the first main side plate may have a window portion that penetrates the first main side plate, facing the holding piece.

[0013] With this configuration, the object held by the holding piece can be exposed to the outside of the packaging container through the window portion, and therefore, by displaying the object while it is still contained in the packaging container, the object can be viewed from outside the packaging container.

[0014] In a fifth aspect disclosed in the present specification, in the fourth aspect, the packaging container may further include a lid that can open and close an opening of the packaging container. In this case, the lid may close the window when the opening of the packaging container is closed.

[0015] According to this configuration, by closing the lid, the packaging container can be sealed and the window can be closed.

[0016] A sixth aspect disclosed in the present specification is that, in the fourth or fifth aspect, the packaging container may further include a cover piece that is arranged on top of the retaining piece facing the window portion and at least partially covers the retaining piece facing the window portion.

[0017] According to this configuration, the cover piece can cover the portion of the holding piece that is exposed through the window portion, thereby preventing the holding piece from being exposed to the outside of the packaging container through the window portion.

[0018] A seventh aspect disclosed in the present specification is any one of the first to sixth aspects, wherein the packaging container further comprises a secondary side plate extending from the first main side plate toward the second main side plate along the periphery of the first main side plate.

[0019] According to this configuration, the secondary side plate can ensure a gap between the first main side plate and the second main side plate.

[0020] An eighth aspect disclosed in this specification may be any one of the fifth to seventh aspects, wherein the lid portion is connected to the second main side plate, and the lid portion may be attachable to another packaging container beyond the first main side plate when the other packaging container is stacked on the first main side plate of the packaging container.

[0021] According to this configuration, two packaging containers can be connected together using the lids of the packaging containers, which allows the two packaging containers to be delivered, stored, etc. together.

[0022] A ninth aspect disclosed in the present specification relates to a deployment body. The deployment body may be composed of a single flat plate, and may be capable of assembling the packaging container according to any one of the first to eighth aspects. [Brief explanation of the drawings]

For example, by closing the lid portion 22, the packaging container 10 is used as a packaging container for storing and shipping an object. The packaging container 10 has dimensions that allow it to be placed in a mailbox. In a variant, the packaging container 10 may have dimensions that make it unable to be placed in a mailbox.

[0029] (Configuration of the deployment body) FIG. 4 shows a plan view of the unfolded body BL of the packaging container 10. FIG. 4 is a view of the unfolded body BL as seen from the inner side of the assembled packaging container 10. Hereinafter, the directions of the unfolded body BL described refer to the directions of the assembled packaging container 10. As shown in FIG. 4, the packaging container 10 is assembled by folding the unfolded body BL made of a single piece of corrugated cardboard along the fold lines. The packaging container 10 may be made of cardboard, plastic, or other materials, and there is no limitation on the material. In FIG. 4, the fold lines are depicted with thin dashed lines. Grooves are formed in the fold lines to facilitate folding. In a modified example, the fold lines may not have grooves, as in other parts. The break lines are depicted with thick dashed lines. Perforations are formed in the break lines to facilitate breaking. As shown in FIG. 4, the packaging container 10 includes, in addition to main side panels 12, 14, secondary side panels 16, 18, 20, and a lid portion 22, a retaining piece 24, a cover piece 26, insertion pieces 30, 32, 34, flaps 36, 38, 40, 42, 46, 48, and insertion openings 44, 50, 52.

[0030] Each of the main side panels 12, 14 has a generally rectangular, flat plate shape. The main side panel 12 has a window portion 28 and a break line portion 60. The window portion 28 penetrates the main side panel 12. The window portion 28 communicates with the opening of the packaging container 10 at the upper edge of the main side panel 12. The window portion 28 has a generally trapezoidal shape with its upper edge longer than its lower edge. In a modified example, the window portion 28 may have another quadrangular shape, such as a rectangle or a square. In another modified example, the window portion 28 may have a polygonal or circular shape. The break line portion 60 extends from the left edge to the right edge at the lower end of the window portion 28. The break line portion 60 has perforations, i.e., a group of slits that intermittently penetrate the main side panel 12. The area surrounded by the break line portion 60 and the lower edge of the window portion 28 at least partially overlaps with the lid portion 22 when the lid portion 22 is closed. The enclosed area has a substantially rectangular shape. An insertion portion 62 is disposed in the center of the breaking line portion 60 in the left-right direction. Slits are formed on both the left and right ends of the insertion portion 62. The insertion portion 62 is connected to the main side plate 12 at the end (lower end) opposite the breaking line portion 60.

[0031] The secondary side plates 16, 20 are connected to the main side plate 12 via fold lines at the left and right edges of the main side plate 12. The secondary side plates 16, 20 are arranged along the entire vertical length of the main side plate 12. The secondary side plates 16, 20 have the same shape. The secondary side plates 16, 20 have an elongated shape in the vertical direction. Flaps 36, 48 are connected to the upper edges of the secondary side plates 16, 20 via fold lines. The flaps 36, 48 have the same shape. A flap 46 is connected to the side of the secondary side plate 16 opposite the main side plate 12 via a fold line. Insertion openings 50, 52 are located on the fold line between the secondary side plate 16 and the flap 46. The insertion openings 50, 52 are each formed by a slit extending along the fold line between the secondary side plate 16 and the flap 46.

[0032] The main side panel 14 is connected to the secondary side panel 20 on the side opposite the main side panel 12 via a bend line. Insert pieces 30, 32 are connected to the main side panel 14 via a bend line. The insert pieces 30, 32 are arranged along the edge of the main side panel 14 on the side opposite the secondary side panel 20. The insert pieces 30, 32 have the same shape. The insert piece 34 is connected to the lower edge of the main side panel 14 via a bend line. The insert piece 30 is formed so that it can be inserted into the insertion opening 50. The insert piece 32 is formed so that it can be inserted into the insertion opening 52.

[0033] A secondary side plate 18 is connected to the lower edge of the main side plate 12 via a fold line. The secondary side plate 18 is arranged over the entire length of the main side plate 12 in the left-right direction. The secondary side plate 18 has an elongated shape in the left-right direction. A flap 40 is connected to the end of the secondary side plate 18 facing the secondary side plate 20 (i.e., the right end) via a fold line. A flap 42 is connected to the end of the secondary side plate 18 facing the secondary side plate 16 (i.e., the left end) via a fold line. A flap 38 is connected to the side of the secondary side plate 18 opposite the main side plate 12 via a fold line. An insertion opening 44 is arranged on the fold line between the flap 38 and the secondary side plate 18. The insertion opening 44 is formed by a slit extending along the fold line between the secondary side plate 18 and the flap 38. The insertion opening 44 is formed so that the insertion piece 34 can be inserted therein. The flap 38 has an engaging portion 38a at its end on the secondary side panel 16 side (i.e., the left end). The engaging portion 38a is disposed at a position where it overlaps with the flap 46 when the packaging container 10 is assembled. The flap 46 has an engaging portion 46a at its end on the secondary side panel 18 side (i.e., the lower end). The engaging portion 38a of the flap 38 and the engaging portion 46a of the flap 46 engage with each other when the packaging container 10 is assembled.

[0034] A retaining piece 24 is connected to the main side panel 12 on the side opposite the secondary side panel 18 via a bending line L1. The retaining piece 24 has a generally rectangular flat plate shape. The retaining piece 24 has a main portion 24a and connecting portions 24b, 24b. The main portion 24a has a generally rectangular flat plate shape. The connecting portions 24b, 24b connect the main portion 24a to the main side panel 12. The connecting portions 24b, 24b are connected to the main portion 24a via a bending line L2. One of the connecting portions 24b, 24b is located at the left end of the upper edge of the main side panel 12. The other of the connecting portions 24b, 24b is located at the right end of the upper edge of the main side panel 12.

[0035] A cover piece 26 is connected to the retaining piece 24 via a bending line L2. In the deployable body BL, the cover piece 26 is located within a window portion 28 of the main side plate 12. The cover piece 26 is cut off from the main side plate 12 at the window portion 28. In other words, the window portion 28 is formed in the main side plate 12 by cutting the cover piece 26 out of a flat plate. The cover piece 26 is also cut off from the connecting portion 24b of the retaining piece 24. The cover piece 26 is connected to the main side plate 12 via the retaining piece 24. The cover piece 26 has substantially the same shape as the window portion 28. In a modified example, the cover piece 26 may have a shape different from that of the window portion 28.

[0036] The holding piece 24 has a hook portion 58 at the center position in the left-right direction of the main portion 24a. The hook portion 58 has a generally rectangular flat plate shape. The hook portion 58 is connected to the cover piece 26 via a folding line L2. The hook portion 58 is connected to the main portion 24a via a break line. The hook portion 58 has a hook hole 58a that penetrates the plate-shaped hook portion 58. The hook hole 58a is formed by an opening that extends in the left-right direction and another opening that extends from the center position of the opening in the left-right direction to the opposite side of the folding line L2 between the opening and the cover piece 26.

[0037] With reference to FIG. 3, the configurations of the retaining piece 24 and the cover piece 26 when the packaging container 10 is assembled will be described. The retaining piece 24 is disposed in the gap between the main side plates 12, 14. The main portion 24a of the retaining piece 24 extends along the main side plate 12 in the gap between the main side plates 12, 14. The connecting portions 24b, 24b extend from the main side plate 12 toward the main side plate 14. The main portion 24a of the retaining piece 24 is disposed so as to face the window portion 28 of the main side plate 12. In the packaging container 10, the length of each of the connecting portions 24b, 24b in the front-to-back direction is shorter than the length of the gap between the main side plates 12, 14 in the front-to-back direction. That is, the upper edge of the main portion 24a (i.e., the fold line L2) is spaced apart from the main side plates 12, 14. The cover piece 26 partially overlaps the main side plate 12.

[0038] Returning to the description of the deployable body BL with reference to FIG. 4, as shown in FIG. 4, the lid portion 22 is connected to the upper edge of the main side plate 14 via a fold line L3. In the deployable body BL, the fold line L3 is aligned with the fold line L1 between the main side plate 12 and the holding piece 24. The lid portion 22 has a substantially rectangular shape. The lid portion 22 has a main body portion 22a and a tip portion 22b. The main body portion 22a is connected to the main side plate 14. An adhesive seal 64 for closing the opening of the packaging container 10 is disposed on the tip portion 22b. A mark 66 for aligning the adhesive seal 64 is disposed on the tip portion 22b. The left-right length of the main body portion 22a is the same as the left-right length of the main side plate 14. The left-right length of the tip portion 22b of the lid portion 22 is shorter than the left-right length of the main side plate 14.

[0039] The lid portion 22 has fold lines L4 and L5 in addition to the fold line L3. Each of the fold lines L3, L4, and L5 runs parallel to the upper edge of the main side panel 14. The fold line L4 is located between the fold lines L3 and L5. The distance between the fold lines L3 and L4 and the distance between the fold lines L4 and L5 are equal to each other. The distance between the fold lines L3 and L4 and the distance between the fold lines L4 and L5 are each slightly larger than the distance between the main side panels 12 and 14.

[0040] As shown in Fig. 4, the main side plate 14 has a slit-shaped lid fixing portion 14a. The lid fixing portion 14a penetrates the main side plate 14. The lid fixing portion 14a is positioned to receive the corner of the tip end 22b of the lid portion 22 when the lid portion 22 is bent toward the back surface of the main side plate 14 at the bending line L3. This allows the lid portion 22 to be fixed in a bent state at the bending line L3.

[0041] (Method of assembling packaging container) A method for assembling the packaging container 10 from the unfoldable body BL will be described with reference to FIGS. 5 to 10. As shown in FIG. 5, the packaging container 10 can be assembled after placing a T-shirt TS on the unfoldable body BL shown in FIG. 4. Before placing the T-shirt TS on the unfoldable body BL, the cover piece 26 is folded along the fold line L2 so as to overlap the holding piece 24. Next, the T-shirt TS is placed so that the collar is located at the upper end of the window portion 28. However, the orientation of the T-shirt TS is not particularly limited. For example, in FIG. 5, the T-shirt TS may be placed upside down.

[0042] Next, the holding piece 24 is folded along the folding lines L1 and L2. As a result, as shown in FIG. 6, the main portion 24a of the holding piece 24 is placed on top of the T-shirt TS. Although not shown in FIG. 6, the connecting portion 24b of the holding piece 24 stands upright from the upper edge of the main side panel 12 toward the main portion 24a, i.e., on the front side of the page. The cover piece 26 is folded together with the holding piece 24. In FIG. 6, the cover piece 26 is positioned between the holding piece 24 and the T-shirt TS and is not visible.

[0043] Next, as shown in Fig. 7, the T-shirt TS is folded in the left-right direction so that the body fits into the main side plate 12. At this time, the T-shirt TS is folded along the left and right edges of the holding pieces 24. Next, as shown in Fig. 8, the T-shirt TS is folded in the up-down direction so that the body fits into the main side plate 12.

[0044] Next, the fold lines between the secondary side panel 18 and the main side panel 12, the fold lines between the flap 38 and the secondary side panel 18, the fold lines between the flap 40 and the secondary side panel 18, and the fold lines between the flap 42 and the secondary side panel 18 are bent. Next, the fold lines between the secondary side panel 16 and the main side panel 12 and the fold line between the flap 46 and the secondary side panel 16 are bent. As a result, the secondary side panel 18 stands upright from the lower edge of the main side panel 12, and the secondary side panel 16 stands upright from the left edge of the main side panel 12. Next, as shown in FIG. 9 , the flaps 38 and 46 are arranged in order so as to face the main side panel 12 with the T-shirt TS sandwiched between them. At this time, the engaging portion 46a of the flap 46 engages with the engaging portion 38a of the flap 38, preventing the secondary side panels 18 and 16 from tipping over relative to the main side panel 12. This allows the user to easily assemble the packaging container 10. The flap 40 is disposed along the inner surface of the secondary side panel 20. Although not shown in FIG.

[0045] Next, the fold line between the main side plate 12 and the secondary side plate 20 and the fold line between the secondary side plate 20 and the main side plate 14 are bent. In addition, the fold lines between the insertion pieces 30, 32, 34 and the main side plate 14 are bent. The folded insertion pieces 30, 32, 34 are inserted into the insertion openings 50, 52, 44, respectively. As a result, the packaging container 10 can be assembled with the T-shirt TS contained in it, as shown in FIG. 10 .

[0046] In the packaging container 10 of this embodiment, T-shirts TS are stored in the gap between the main side plates 12 and 14. While stored, the T-shirts TS are held by being pinched by the holding pieces 24. With this configuration, the orientation of the stored T-shirts TS is maintained by the holding pieces 24 within the packaging container 10. Therefore, the T-shirts TS are prevented from being stored unevenly within the packaging container 10. Furthermore, because the T-shirts TS are held by the holding pieces 24 that are integrated with the main side plates 12, there is no need to provide a separate member to maintain the orientation of the T-shirts TS.

[0047] In this embodiment, the holding piece 24 sandwiches the T-shirt TS together with the main side plate 12 between itself and the main side plate 12. With this configuration, the object can be held by the holding piece 24 and the main side plate 12. Furthermore, the holding piece 24 holds the T-shirt TS by arranging it around the holding piece 24 from the main side plate 12 to the main side plate 14. With this configuration, when folding the object to store it as in this embodiment, the holding piece 24 can function as a guide when folding the T-shirt TS.

[0048] In this embodiment, the main side plate 12 has a window portion 28 penetrating the main side plate 12, facing the holding piece 24. With this configuration, as shown in Fig. 10, the T-shirts TS held by the holding piece 24 can be exposed to the outside of the packaging container 10 through the window portion 28. Therefore, by displaying the T-shirts TS while they are still stored inside, the T-shirts TS can be viewed from outside the packaging container 10.

[0049] In this embodiment, the cover piece 26 is disposed so as to overlap the holding piece 24 facing the window portion 28. In addition, the cover piece 26 partially covers the window portion 28 side of the holding piece 24. With this configuration, the cover piece 26 can cover the portion of the holding piece 24 that is exposed from the window portion 28. This makes it possible to prevent the holding piece 24 from being exposed to the outside of the packaging container 10 through the window portion 28.

[0050] For example, when the packaging container 10 is laid flat to display the T-shirts TS, the lid portion 22 is folded at the folding line L3 between the main side plate 14 and the lid portion 22, and is positioned so as to face the back surface of the main side plate 14. At this time, the corner of the tip portion 22b of the lid portion 22 is inserted into the lid fixing portion 14a of the main side plate 14, thereby fixing the lid portion 22 to the main side plate 14. Because the lid portion 22 is fixed by the lid fixing portion 14a, the lid portion 22 does not get in the way when the packaging container 10 is displayed, resulting in a beautiful appearance. In addition, the T-shirts TS can be easily viewed.

[0051] The configuration of the lid fastening portion 14a is not particularly limited. As shown in FIG. 11 , when the lid portion 22 is bent toward the back surface of the main side plate 14 at the bending line L3, the lid fastening portion 14a is curved and protrudes toward the side of the main side plate 14 opposite the side from which the corner of the lid portion 22 protrudes. In a modified example, the lid fastening portion 14a does not have to be curved. The lid fastening portion 14a may be linear. Slits extending along the periphery of the received lid portion 22 are formed at the left end, right end, and center of the lid fastening portion 14a. This makes it easy to insert the corner of the lid portion 22 into the lid fastening portion 14a when fastening the lid portion 22.

[0052] 12, for example, when displaying the packaging container 10 by hanging it, the breaking line between the holding piece 24 and the hook portion 58 is broken, and the hook portion 58 of the packaging container 10 can be pulled out upward from the holding piece 24. By hooking the hook hole 58a of the pulled-out hook portion 58 onto a rod-shaped hook or the like for display, the packaging container 10 can be hung and displayed.

[0053] When the lid portion 22 of the packaging container 10 is closed to pack a T-shirt TS from the state shown in FIG. 10 , the lid portion 22 is folded along the fold line L3 between the lid portion 22 and the main side plate 14. The lid portion 22 is then positioned to cover the gap between the main side plates 12 and 14, covering the upper end between the main side plates 12 and 14. That is, the lid portion 22 closes the opening of the packaging container 10. The lid portion 22 is also folded along the fold line L4. As a result, as shown in FIG. 1 , the lid portion 22 closes the window portion 28 while closing the opening of the packaging container 10. With this configuration, closing the lid portion 22 can seal the packaging container 10 and close the window portion 28. The lid portion 22 is attached above the break line 60 of the main side plate 12 with an adhesive, such as an adhesive seal 64. This closes the lid portion 22.

[0054] 1, when opening the packaging container 10 with the lid portion 22 closed, the user inserts a finger into the insertion portion 62 of the main side panel 12 to break the breaking line portion 60. As a result, the region of the main side panel 12 to which the lid portion 22 is adhered is separated from the main side panel 12 together with the lid portion 22 by the breaking line portion 60. As a result, the packaging container 10 is opened.

[0055] 10 is folded along the fold line between the flap 36 and the secondary side plate 16, and the flap 48 is folded along the fold line between the flap 36 and the secondary side plate 20. Each of the flaps 36, 48 may be arranged along the connecting portion 24b of the holding piece 24 or along the inner surface of each of the secondary side plates 16, 20, depending on the application of the packaging container 10.

[0056] Another method of using the packaging container 10 will be described with reference to Figures 13 and 14. Figures 13 and 14 show a state in which another packaging container 110 is stacked on top of the packaging container 10. In Figure 14, the packaging container 110 is colored gray for ease of viewing. As shown in Figures 13 and 14, the packaging container 110 has the same configuration as the packaging container 10, and includes main side plates 112 and 114, three secondary side plates 118 and 120 extending from the main side plate 112 toward the main side plate 114, and a lid portion 122. The main side plate 12 of the packaging container 10 and the main side plate 112 of the packaging container 110 are stacked facing each other. The packaging container 10 is arranged so that the lid portion 22 is upside down relative to the lid portion 122 of the packaging container 110. In the packaging container 10, the lid portion 22 is folded along the folding lines L3 and L5, respectively, and the lid portion 22 is attached to the main side plate 114 of the packaging container 110. That is, the lid portion 22 of the packaging container 10 is attached to the packaging container 110 beyond the main side plate 12 of the packaging container 10, with the packaging container 110 overlapping the main side plate 12 of the packaging container 10, in a state where the packaging container 110 is placed on the main side plate 12 of the packaging container 10. Similar to the lid portion 22 of the packaging container 10, the lid portion 122 of the packaging container 110 is attached to the packaging container 10. With this configuration, the two packaging containers 10, 110 can be connected using the lid portions 22, 122 of the packaging containers 10, 110. This allows the two packaging containers 10, 110 to be delivered, stored, etc. together as a packaging container unit.

[0057] Furthermore, since the two packaging containers 10, 110 are arranged so that their vertical orientations are different from each other, the orientations of the lid portions 22, 122 are different from each other. The length from the fold line L5 of the lid portion 22 to the tip of the lid portion 22 is less than half the vertical length of the packaging container 10. Therefore, when the packaging container units are stacked in the front-to-back direction, the lid portions 22, 122 of two adjacent packaging container units do not overlap in the front-to-back direction. This makes it difficult for the stacked packaging units to tip over, even when multiple packaging container units are stacked in the front-to-back direction. In a modified example, the packaging container 110 may have a shape different from that of the packaging container 10, rather than being the same shape as the packaging container 10.

[0058] (Correspondence) The main side plate 12 is an example of a "first main side plate." The main side plate 14 is an example of a "second main side plate." The secondary side plates 16, 18, and 20 are examples of "secondary side plates." In this embodiment, the cover piece 26 also holds the T-shirt TS together with the holding piece 24. Therefore, the cover piece 26 is an example of a "holding piece."

[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 alterations of the specific examples exemplified above.

[0060] (1) The object to be stored in the packaging container 10 is not limited to a T-shirt. The object may be a shirt other than a T-shirt. The object may be, for example, a dress shirt, a blouse, etc. In a modified example, the object may be clothing other than a shirt. In a modified example, the object does not have to be clothing. The object may be, for example, an accessory such as a tie or a scarf. In another modified example, the object may be a towel, a handkerchief, etc. This technology is effective for objects that have difficulty maintaining their own posture. Preferably, the object may be foldable.

[0061] (2) The holding piece 24 does not need to be arranged around the holding piece 24. For example, the holding piece 24 may simply hold the object by sandwiching it between the holding piece 24 and the main side plate 12.

[0062] (3) The window portion 28 of the main side plate 12 and the opening of the packaging container 10 may be independent. In this case, the lid portion 22 may close the window portion 28 while closing the opening of the packaging container 10. In a modified example, the main side plate 12 may not have the window portion 28.

[0063] (4) The size of the cover piece 26 is not limited to that of the above embodiment. The cover piece 26 may cover the entire holding piece 24. The cover piece 26 only needs to cover at least the upper end portion of the holding piece 24 that is exposed through the window portion 28. In a modified example, the packaging container 10 may not have a cover piece 26.

[0064] (5) The packaging container 10 includes secondary side plates 16, 18, and 20 in addition to the main side plates 12 and 14. With this configuration, the secondary side plates 16, 18, and 20 can ensure a gap between the main side plate 12 and the main side plate 14. In a modified example, the packaging container 10 does not need to include the secondary side plates 16, 18, and 20. For example, the main side plates 12 and 14 of the packaging container 10 may be directly connected. That is, the packaging container 10 may be an envelope-shaped container.

[0065] (6) The packaging container 10 does not have to have the lid portion 22. That is, the opening of the packaging container 10 may be open.

[0066] Furthermore, the technical elements described in this specification or drawings may exhibit technical utility alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. Furthermore, the technologies illustrated in this specification or drawings simultaneously achieve multiple objectives, and achieving one of those objectives alone has technical utility.
