[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-2678 Summary of the Invention [Problem to be solved by the invention]

[0004] In the cup collecting carton described above, the cup containers are exposed while being supported by the cup collecting carton.

[0005] The present specification provides a technique for holding an object and storing the object.

[0006] A first aspect disclosed in this specification relates to a packaging container. The packaging container may be made from a single deployable body and include a main body defining a storage space, and a support member connected to the main body via a fold line and disposed in the storage space.

[0007] According to this configuration, a configuration in which the object can be held by the support member and the object can be accommodated in the accommodation space can be produced from a single deployable body.

[0008] A second aspect disclosed in this specification is that, in the first aspect described above, the main body portion comprises a pair of first side plates facing each other across the support member, and a first engagement piece extending from at least one of the pair of first side plates toward the support member, and the support member may further comprise a second engagement piece that engages with the first engagement piece.

[0009] According to this configuration, by engaging the first engaging piece with the second engaging piece, the first side plate and the support member can be maintained in an engaged state with each other, thereby preventing the packaging container from collapsing.

[0010] A third aspect disclosed in this specification is, in the first or second aspect, the main body portion comprises a bottom plate and a retaining plate extending upward from the bottom plate, the support member is arranged with a specific distance between it and the bottom plate, sandwiching the retaining plate therebetween, and comprises a through hole for receiving an object, and an inclined plate extending from the peripheral edge of the through hole toward the inner side, the length of the inclined plate from a first end on the peripheral edge side of the through hole to a second end on the opposite side is longer than the specific distance, and the inclined plate may be arranged at an angle with respect to the bottom plate, with the first end connected to the peripheral edge of the through hole and the second end in contact with the bottom plate.

[0011] According to this configuration, the object can be brought into contact with the inclined plate by inserting the object into the through-hole of the support member, thereby supporting the object at an angle relative to the bottom.

[0012] A fourth aspect disclosed in this specification may be such that, in the first or second aspect, the main body comprises a lid and a bottom connected to the lid via a fold line, and the lid comprises a top panel connected to the bottom via a specific fold line, a pair of second side panels connected to the top panel and facing each other across the specific fold line, and a front panel connected to each of the top panel and the pair of second side panels.

[0013] According to this configuration, by disposing a front panel on the lid, the front of the packaging container can be opened widely when the lid is open, thereby making it easier to see the object when the lid is open.

[0014] A fifth aspect disclosed in this specification is that, in the above-mentioned fourth aspect, the cover portion further comprises an overlapping plate connected to the edge of the front panel opposite the top panel via a fold line, the overlapping plate being arranged overlapping the inner surface of the front panel, an extension piece extending from each of the pair of second side panels between the front panel and the overlapping plate, and an insertion piece extending from between the front panel and the overlapping plate toward the main body portion, and the main body portion may have an insertion hole for receiving the insertion piece.

[0015] With this configuration, the pair of second side panels can be positioned relative to the front panel by sandwiching the extension pieces between the front panel and the overlapping panel, which prevents the packaging container from collapsing. Also, by inserting the insertion pieces into the insertion holes, the lid portion can be fixed to the main body portion.

[0016] A deployable body that is made of a single flat plate and can be used to prepare the above-mentioned packaging container is also novel and useful. [Brief explanation of the drawings]

[0018] (Example) (Structure of packaging container 2) The packaging container 2 is a deployable body that can be deployed between an open state and a closed state. FIG. 1 shows the packaging container 2 in an open state. FIG. 2 shows the packaging container 2 in a closed state. The packaging container 2 has a rectangular parallelepiped shape in the closed state. The packaging container 2 may have other shapes, such as a cube, in the closed state. The packaging container 2 is used to package, transport, and store objects 90a, 90b (see FIG. 8) to be stored therein. In this embodiment, as shown in FIGS. 1 and 2, the up-down direction, the front-rear direction, and the left-right direction are each shown. These up-down direction, the front-rear direction, and the left-right direction are used to facilitate the explanation of this embodiment and do not indicate the directions in which the packaging container 2 is used when in use.

[0019] The packaging container 2 comprises a main body 4 and a support member 10. The main body 4 defines a storage space 100. The support member 10 is connected to the main body 4 via a fold line 10a. The support member 10 is stored in the storage space 100. The main body 4 comprises a lid 20 and a bottom 30. The lid 20 rotates relative to the bottom 30, switching the packaging container 2 between an open state and a closed state.

[0020] As shown in FIG. 3, the packaging container 2 is produced by assembling the deployable bodies 3. The deployable body 3 is a single sheet of flat corrugated cardboard. The deployable body 3 is not limited to corrugated cardboard, and may be made of, for example, flat cardboard, resin, etc. FIG. 3 shows the inner surface of the packaging container 2. Also, in FIG. 3, fold lines are indicated by thin dashed lines. Grooves are formed in the corrugated cardboard at the locations corresponding to the fold lines so that the corrugated cardboard is easier to fold than other parts. In the packaging container 2, a configuration in which an object can be held by the support member 10 and an object can be stored in the storage space 100 can be produced from a single deployable body 3.

[0021] Unless otherwise noted, the following description will be given using the directions in the closed state shown in FIG. 2 after the deployable body 3 is assembled into the packaging container 2.

[0022] The bottom portion 30 includes a rear panel 31, a bottom panel 32, a pair of third flaps 33a, 33b, a retaining panel 34, a pair of first side panels 36a, 36b, and a pair of first engagement pieces 38a, 38b. The bottom panel 32 has a rectangular flat plate shape. The rear panel 31 is connected to the rear edge of the bottom panel 32 via a fold line 30a. The rear panel 31 has a rectangular flat plate shape. The upper edge of the rear panel 31 is connected to the lid portion 20 via a fold line 20a. The retaining panel 34 is connected to the front edge of the bottom panel 32 via a fold line 30b. The retaining panel 34 has a rectangular flat plate shape. The retaining panel 34 is shorter than the rear panel 31 in the vertical direction. The length of the retaining panel 34 in the vertical direction may be half or less of the length of the rear panel 31.

[0023] An insertion hole 39 is formed on the fold line 30b at the boundary between the bottom plate 32 and the holding plate 34. The insertion hole 39 is located in the center in the left-right direction. The insertion hole 39 is a through hole that has a width in the left-right direction.

[0024] A pair of first side plates 36a, 36b are connected to both left and right end edges of the back plate 31 via bending lines 30c, 30d, respectively. The first side plate 36a has an edge that curves in a substantially arc shape from the back plate 31 side toward the front. The first side plate 36b has a similar configuration to the first side plate 36a.

[0025] A pair of third flaps 33a, 33b are connected to the lower edges of the pair of first side plates 36a, 36b via folding lines 30g, 30h, respectively. Each of the pair of third flaps 33a, 33b has a generally rectangular flat plate shape.

[0026] A pair of first engagement pieces 38a, 38b are connected to the front edges of the pair of first side plates 36a, 36b via bending lines 30e, 30f, respectively. Each of the pair of first engagement pieces 38a, 38b has a generally rectangular flat plate shape. In the vertical direction, each of the pair of first engagement pieces 38a, 38b has the same length as the back panel 31.

[0027] The support member 10 includes a support plate 10b, a first flap 11, through holes 12a, 12b, inclined plates 14a, 14b, and a pair of second engagement pieces 16a, 16b. The support plate 10b has a rectangular flat plate shape slightly smaller than the bottom plate 32. Through holes 12a, 12b are arranged in the support plate 10b. The through holes 12a, 12b penetrate the support plate 10b. The shapes of the through holes 12a, 12b are appropriately set to match the objects 90a, 90b. The through holes 12a, 12b may have different shapes. The through holes 12a, 12b may have a polygonal shape such as a rectangle or a triangle to match the shape of the objects to be accommodated. The number of through holes 12a, 12b is not particularly limited. The number of through holes 12a, 12b provided in the support plate 10b may be one, or three or more.

[0028] The through holes 12a, 12b are located rearward of the bending line 10a. That is, the through holes 12a, 12b extend from the front edge of the support plate 10b to just before the rear edge of the support plate 10b. An inclined plate 14a is connected to a first end 13a located at the front end of the through hole 12a. The inclined plate 14a extends rearward from the first end 13a. A second end 13c located at the rear end of the inclined plate 14a is located forward of the rear end of the through hole 12a. The inclined plate 14a is formed when the through hole 12a is opened in the flat plate that constitutes the support plate 10b. The length from the first end 13a to the second end 13c of the inclined plate 14a is longer than the length of the holding plate 34 in the up-down direction. The inclined plate 14b has a similar configuration to the inclined plate 14a. The inclined plate 14b has a first end 13b and a second end 13d, similar to the first end 13a and second end 13c of the inclined plate 14a.

[0029] A pair of second engagement pieces 16a, 16b are connected to both left and right end edges of the support plate 10b via bending lines 10c, 10d, respectively. Each of the pair of second engagement pieces 16a, 16b has an edge that curves in a substantially arc shape from the holding plate 34 side toward the rear. In the up-down direction, the length of each of the pair of second engagement pieces 16a, 16b is substantially equal to the length of the holding plate 34.

[0030] A first flap 11 is connected to the rear end edge of the support member 10 via a folding line 10e. The first flap 11 has a rectangular flat plate shape. In the up-down direction, the length of the first flap 11 is approximately equal to the length of the holding plate 34.

[0031] The lid portion 20 includes a second flap 21, a top panel 22, a pair of second side panels 24a, 24b, a pair of extension pieces 25a, 25b, a front panel 26, an overlapping panel 28, and an insertion piece 29. The top panel 22 is connected to the upper edge of the back panel 31 via a fold line 20a. The top panel 22 has a rectangular, flat plate shape. The top panel 22 is connected at its left and right edges to the pair of second side panels 24a, 24b via fold lines 20b, 20c. The second side panel 24a has an edge that curves in a substantially arc shape from the top panel 22 side toward the rear. The second side panel 24b has a configuration similar to that of the second side panel 24a.

[0032] An extension piece 25a is connected to the front edge of the second side plate 24a via a fold line 20d. An extension piece 25b is connected to the front edge of the second side plate 24b via a fold line 20e. Each of the pair of extension pieces 25a, 25b has a generally trapezoidal flat plate shape.

[0033] The top panel 22 is connected to the front panel 26 at its front edge via a fold line 20f. The front panel 26 has a rectangular flat plate shape. In the vertical direction, the front panel 26 has the same length as the back panel 31. In a modified example, the total length of the front panel 26 and the holding plate 34 in the vertical direction may be equal to or greater than the length of the back panel 31, i.e., the height of the packaging container 2. The front panel 26 is connected to the overlapping panel 28 at its lower edge via a fold line 20g. The overlapping panel 28 has a rectangular flat plate shape that is slightly smaller than the front panel 26.

[0034] An insertion piece 29 is formed spanning from the lower end of the front plate 26 to the lower end of the overlapping plate 28. The insertion piece 29 has a slit 29a along the bending line 20g. The insertion piece 29 can be bent along the slit 29a. In the left-right direction, the insertion piece 29 is positioned so as to overlap with the insertion hole 39. In the left-right direction, the length of the insertion piece 29 rearward of the slit 29a is slightly shorter than the length of the insertion hole 39.

[0035] The overlapping plate 28 is connected at its upper edge to the second flap 21 via a fold line 20h. The second flap 21 has a rectangular flat plate shape. In the left-right direction, the second flap 21 is slightly shorter than the front plate 26 and slightly longer than the overlapping plate 28. A perforated slit portion 21a is formed in the fold line 20h.

[0036] (Method of assembling the deployment body 3 and the packaging container 2) 4 to 7, an assembly method for assembling the packaging container 2 from the deployable body 3 will be described. The packaging container 2 is produced by assembling the lid section 20 and the bottom section 30 from the deployable body 3. As shown in FIG. 4, in the lid section 20, each of the pair of second side plates 24a, 24b from the deployable body 3 is folded relative to the top panel 22 at folding lines 20b, 20c so that the pair of second side plates 24a, 24b face each other with the top panel 22 in between. Each of the pair of extension pieces 25a, 25b is folded at a right angle relative to the pair of second side plates 24a, 24b at folding lines 20d, 20e toward the inside of the packaging container 2. The pair of extension pieces 25a, 25b are arranged with a gap between them in the left-right direction.

[0037] Next, the front panel 26 is bent relative to the top panel 22 to a position where it contacts the pair of extension pieces 25a, 25b. As shown in FIG. 5 , the overlapping panel 28 is bent relative to the front panel 26 so that the pair of extension pieces 25a, 25b are sandwiched between the front panel 26 and the overlapping panel 28. As a result, the front panel 26 and the overlapping panel 28 are positioned overlapping each other. The extension pieces 25a, 25b are positioned between the front panel 26 and the overlapping panel 28. In addition, the second flap 21 is bent along the inner surface of the top panel 22 so that it contacts the top panel 22. With this configuration, by sandwiching the pair of extension pieces 25a, 25b between the front panel 26 and the overlapping panel 28, the pair of second side panels 24a, 24b can be positioned relative to the front panel 26. Furthermore, by fitting the second flap 21 into the pair of second side plates 24a, 24b, the front plate 26 and the overlapping plate 28 can be positioned relative to the top plate 22. This makes it possible to prevent the packaging container 2 from collapsing.

[0038] 6, each of the pair of first side plates 36a, 36b is folded relative to the back plate 31 along folding lines 30c, 30d so that the pair of first side plates 36a, 36b face each other across the back plate 31. Each of the pair of third flaps 33a, 33b is folded at a right angle relative to the pair of first side plates 36a, 36b toward the inside of the packaging container 2 along folding lines 30g, 30h. Each of the pair of first engagement pieces 38a, 38b is folded at a right angle toward the inside of the pair of first side plates 36a, 36b along folding lines 30e, 30f.

[0039] Further, at each of the folding lines 10c and 10d, the pair of second engagement pieces 16a and 16b are folded relative to the support member 10 so that the pair of second engagement pieces 16a and 16b face each other across the support member 10. At the folding line 10e, the first flap 11 is folded at a right angle relative to the support member 10.

[0040] Next, as shown in Fig. 7, the back panel 31 is bent along the folding line 30a to a position where each of the pair of third flaps 33a, 33b contacts the bottom panel 32. The retaining plate 34 is bent at a right angle to the bottom panel 32 along the folding line 30b. At this time, the retaining plate 34 is bent relative to the bottom panel 32 so that each of the pair of second engagement pieces 16a, 16b is positioned inside each of the pair of first side panels 36a, 36b. Furthermore, with the retaining plate 34 bent relative to the bottom panel 32, the second engagement piece 16a and the first engagement piece 38a are positioned so that the portion 16c located at the upper end of the front end of the second engagement piece 16a and the upper end portion 38c of the first engagement piece 38a are adjacent to each other. Similarly, the second engagement piece 16b and the first engagement piece 38b are arranged at positions where the upper front end portion 16d of the second engagement piece 16b and the upper end portion 38d of the first engagement piece 38b are adjacent to each other.

[0041] Next, the support member 10 is bent toward the holding plate 34 at the bending line 10a. The support member 10 is bent toward the holding plate 34 to a position where the tip 11a of the first flap 11 contacts each of the pair of third flaps 33a, 33b. The first flap 11 may have a flat plate shape such that the tip 11a of the first flap 11 contacts the bottom plate 32 when the support member 10 is bent toward the holding plate 34. The tip 11a of the first flap 11 contacts each of the pair of third flaps 33a, 33b, thereby positioning the support plate 10b with respect to the bottom plate 32. By bending the support member 10 toward the holding plate 34, the second engagement piece 16a and the first engagement piece 38a engage with each other. Specifically, a portion 16c located at the upper end of the front end of the second engagement piece 16a comes into contact with an upper end portion 38c of the first engagement piece 38a, whereby the second engagement piece 16a is caught on the first engagement piece 38a. Similarly, a portion 16d located at the upper end of the front end of the second engagement piece 16b comes into contact with an upper end portion 38d of the first engagement piece 38b, whereby the second engagement piece 16b is caught on the first engagement piece 38b. With this configuration, the packaging container 2 assembled from the deployable body 3 can maintain a state in which the pair of first side plates 36a, 36b and the support member 10 are engaged with each other. This makes it possible to prevent the packaging container 2 from collapsing.

[0042] Once the positional relationship between the pair of first side plates 36a, 36b and the support member 10 has been determined, the first flap 11 is fitted into the pair of first side plates 36a, 36b, thereby positioning the support member 10 relative to the bottom 30. This completes the packaging container 2 in an open state. In the packaging container 2 assembled from the unfoldable body 3, the support plate 10b is disposed at a distance from the bottom plate 32. The distance between the support plate 10b and the bottom plate 32 is maintained by the holding plate 34 and the first flap 11.

[0043] (effect) In the packaging container 2 in the closed state shown in Figure 2, the insertion piece 29 extends from between the front panel 26 and the overlapping panel 28 of the lid portion 20 toward the insertion hole 39 in the bottom portion 30. At this time, the insertion hole 39 receives the insertion piece 29. With this configuration, the packaging container 2 can fix the lid portion 20 to the main body portion 4 by inserting the insertion piece 29 into the insertion hole 39.

[0044] As shown in FIG. 8 , when the objects 90a, 90b are inserted into the through-holes 12a, 12b of the support member 10, the objects 90a, 90b push the inclined plates 14a, 14b downward. The length of the inclined plate 14a from the first end 13a to the second end 13c is longer than the vertical length of the holding plate 34. With this configuration, when the object 90a is placed on the inclined plate 14a, the second end 13c of the inclined plate 14a contacts the third flap 33a. This allows the inclined plate 14a to be positioned at an incline relative to the bottom plate 32. The inclined plate 14a is inclined downward toward the rear. This allows the inclined plate 14a to support the object 90a inserted into the through-hole 12a with its bottom surface inclined relative to the bottom plate 32. As a result, the side of the object 90a can be positioned facing upward. The user who opens the packaging container 2 can easily see the side of the object 90a. The user can easily recognize the product name and the like displayed on the side of the object 90a. The same applies to the inclined plate 14b.

[0045] In the packaging container 2 in the closed state shown in Fig. 2, the holding plate 34 is disposed on the inner side (rear side) of the overlapping plate 28 and front plate 26 of the lid portion 20. With this configuration, the holding plate 34 can be configured to be shorter in the vertical direction than the back plate 31, i.e., the height of the packaging container 2. This allows the front side of the packaging container 2 to be widely opened when the packaging container 2 is in the open state. This makes it easier to view the objects 90a, 90b when the lid portion 20 is open.

[0046] (Correspondence) Each of the fold lines 20a, 20b, and 20c is an example of a “specific fold line.” The distance between the support plate 10b and the bottom plate 32 is an example of a “specific distance.”

[0047] Although specific examples of the present invention have been described above in detail, these are merely examples and do not limit the scope of the utility model claims. The technology described in the scope of the utility model claims includes various modifications and alterations of the specific examples exemplified above.

[0048] For example, as in a packaging container 200 shown in FIG. 9, the support member 10 may not have inclined plates 14a and 14b. In this case, the packaging container 200 may have through holes 212a and 212b in the support member 10. The number of through holes arranged in the support member 10 is not particularly limited. For example, as in a packaging container 300 shown in FIG. 10, the support member 10 may have three through holes 312a, 312b, and 312c. Furthermore, as in a packaging container 400 shown in FIG. 11, the support member 10 may have only one through hole 412. The packaging containers 300 and 400 may or may not have an inclined plate similar to the inclined plate 14a.

[0049] Furthermore, the shape of the through-holes arranged in the support member 10 is not particularly limited. The through-holes may have a shape that matches the shape of the object. For example, if the object has a long and thin shape like a pen, a rectangular through-hole 512 may be formed as shown in FIG. 12. An inclined plate (two 514a, 514b are shown in FIG. 12) may be connected to each of the four edges of the through-hole 512. The through-hole 512 may be closed by multiple inclined plates in the state of the deployable body 3. The through-hole 512 may be opened when the object is inserted. The multiple inclined plates may be separated from each other in advance by slits.

[0050] The overlapping plate 28 does not have to be provided. The second side plates 24a, 24b may have another shape, such as a rectangle. The first side plates 36a, 36b have a shape that prevents the lid portion 20 from interfering with the lid portion 20 when the lid portion 20 rotates relative to the bottom portion 30. When the packaging container 2 is in the closed state, the second side plates 24a, 24b may overlap the first side plates 36a, 36b, and have a shape that prevents the storage space 100 from being exposed.

[0051] Furthermore, the technical elements described in this specification or drawings may exhibit technical utility either alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. Furthermore, the technologies illustrated in this specification or drawings simultaneously achieve multiple objectives, and achieving one of those objectives is itself technically useful.
