Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the above-described in-box article holding structure, the shape of the annular accommodation space on the upper surface of the inner bottom sheet may be restricted by the connection position between the inner bottom sheet and the belt-like sheet. In such a structure, for example, even if an attempt is made to make the ring smaller to fit a smaller article, the accommodation space may not become small enough and may become distorted, resulting in a large gap that allows the article to move inside. In addition, the above-described in-box article holding structure includes a simple structure in which the inner bottom sheet and the belt-like sheet are connected at one location. In such a structure, the annular accommodation space itself is likely to move on the inner bottom sheet, and the article may move together with the accommodation space inside the storage box. Thus, in the above-described in-box article holding structure, it may be difficult to stably hold the article in the storage box.

[0005] The present invention aims to solve such problems. That is, the present invention aims to provide an in-box article holding structure capable of stably holding articles in a storage box.

Means for Solving the Problems

[0006] To achieve the above object, the in-box article holding structure of the present invention includes a storage box having a box bottom wall and box side walls, and an inner bottom sheet that is placed on the box bottom wall and stored, at least a part of the peripheral edge of which abuts against the box side walls to restrict movement inside the storage box, and a plurality of strip-shaped sheets each formed in a strip shape, one end portion of the long side edge of which is connected to the peripheral edge of the inner bottom sheet at intervals from each other, and centered on the central portion of the inner bottom sheet extending from the peripheral edge along the turning direction a plurality of strip-shaped sheets, and when the plurality of strip-shaped sheets are folded up with the boundary with the inner bottom sheet as a fold line and Ji Xuan combined with each other in a circumferential direction, an article holding space having a cylindrical shape around an axis intersecting the inner bottom sheet is constructed the aforesaid on the surface of the inner bottom sheet on the central side of each strip-shaped sheet. and the inner bottom sheet corresponds one-to-one to a plurality of sides forming a basic polygon according to the shape of the bottom wall of the box, and includes a basic edge portion tracing a part on the downstream side in the turning direction on one side, and an angled edge portion inclined at a predetermined inclination angle with respect to the one side so as to approach the central portion of the inner bottom sheet toward the upstream in the turning direction on the upstream side in the turning direction on the one side, and has a shape surrounded by a plurality of bent edges each constituted by the above, and the plurality of strip-shaped sheets are connected to the angled edge portions at the respective bent edges with an interval of a length corresponding to the basic edge portion therebetween being opened from each other It is characterized by this.

[0007] According to the above-described in-box article holding structure, a plurality of strip-shaped sheets are connected to the inner bottom sheet so as to form spiral arms centered on their central portions. And the article holding space is constructed in a cylindrical shape on the surface of the inner bottom sheet on the downstream side in the turning direction of the spiral arms when the plurality of strip-shaped sheets are combined with each other in the turning direction of the spiral arms. The article holding space constructed in this way will be firmly fixed to the inner bottom sheet at the boundary between the plurality of strip-shaped sheets and the inner bottom sheet. Further, since this article holding space is constructed on the downstream side in the turning direction away from the connection position with the inner bottom sheet in each strip-shaped sheet, its shape is less likely to be restricted by the connection position. Moreover, by appropriately adjusting the constriction diameter in the turning direction when combining the plurality of strip-shaped sheets in the turning direction of the spiral arms according to the size of the article, a gap with the article can be suppressed and a cylindrical article holding space can be constructed. Thus, according to the above-described in-box article holding structure, an article holding space that is less likely to be restricted by the connection position and has a suppressed gap with the article is firmly fixed to the inner bottom sheet, so that the article can be stably held in the storage box.

[0008] Here, it is preferable that the inner bottom sheet corresponds one-to-one to a plurality of sides forming a basic polygon according to the shape of the bottom wall of the box, has a basic edge portion tracing a part on the downstream side in the turning direction on one side, and an angled edge portion inclined at a predetermined inclination angle with respect to the one side so as to approach the central portion of the inner bottom sheet toward the upstream in the turning direction on the upstream side in the turning direction on the one side, and is surrounded by a plurality of bent edges each constituted by these, and the plurality of strip-shaped sheets are connected to the angled edge portions in each of the plurality of bent edges with an interval of a length corresponding to the basic edge portion being opened from each other.

[0009] According to this configuration, each strip-shaped sheet is connected to an angled edge portion that is inclined so as to approach the central portion of the inner bottom sheet toward the upstream in the turning direction at each bent edge. As a result, when a cylindrical article holding space is constructed by being combined in the turning direction, a repulsive force in a direction away from the central portion of the inner bottom sheet strongly acts on the connecting portion between one strip-shaped sheet and the adjacent strip-shaped sheet. As a result, the connection strength between the strip-shaped sheets is strengthened by the above-described repulsive force, and the shape of the article holding space can be stably maintained.

[0010] Further, it is more preferable that the basic polygon is a quadrilateral, the inner bottom sheet has a shape surrounded by four bent edges corresponding one-to-one to the four sides forming the quadrilateral as the plurality of bent edges, and the plurality of strip-shaped sheets are four strip-shaped sheets connected to the angled edge portions at the respective four bent edges.

[0011] According to this configuration, since the article holding space is constructed by four strip-shaped sheets, an excessive load applied from all four directions to this article holding space can be evenly supported by the four strip-shaped sheets, and the article can be held more stably.

[0012] Also, To achieve the above object, the in-box article holding structure of the present invention includes a storage box having a bottom wall of the box and side walls of the box, and a sheet material placed on the bottom wall of the box and stored therein, wherein at least a part of the peripheral edge abuts against the side walls of the box, so that movement inside the storage box is restricted, and an inner bottom sheet, and a plurality of strip-shaped sheets each formed in a strip shape, with one end portion at the long-side edge being connected to the peripheral edge of the inner bottom sheet with an interval therebetween, and extending from the peripheral edge along the turning direction centered on the central portion of the inner bottom sheet, and the plurality of strip-shaped sheets are folded up with the boundary with the inner bottom sheet as a fold line and combined with each other in the turning direction, and an article holding space having a cylindrical shape around an axis intersecting the inner bottom sheet is constructed on the surface of the inner bottom sheet on the center side in each strip-shaped sheet the inner bottom sheet has a polygonal shape corresponding to the shape of the bottom wall of the box, and the plurality of strip-shaped sheets are connected to a part on the upstream side in the turning direction at each of the plurality of edges of the polygonal inner bottom sheet, with intervals of lengths corresponding to the other parts at each edge being opened from each other. characterized by .

[0013] According to this configuration, since the in-box article holding structure is housed in the storage box so that substantially all of the peripheral edge of the inner bottom sheet abuts against the box side wall, the article can be held more stably in the storage box.

[0014] Further, each of the plurality of strip-shaped sheets is provided with a locking portion for locking to a locking destination strip-shaped sheet adjacent to the downstream side in the turning direction at the tip portion in the turning direction on the opposite edge opposite to the long-side edge connected to the inner bottom sheet, and it is preferable that a slit for locking to the locking portion of the locking source strip-shaped sheet adjacent to the upstream side in the turning direction is provided near the end portion on the upstream side in the turning direction on the opposite edge.

[0015] According to this configuration, by locking the locking portion to the slit, it is possible to easily construct an article holding space by combining strip-shaped sheets compared to the case of using a fixing member such as an adhesive tape or a stapler.

[0016] Furthermore, it is more preferable that a plurality of the slits are provided at intervals in the longitudinal direction of the opposite edge.

[0017] According to this configuration, by changing the position of the slit to be locked, it is possible to change the constriction diameter in the turning direction when combining the strip-shaped sheets, and it is possible to easily construct an article holding space with an optimal diameter according to the size of the article.

[0018] Furthermore, it is preferable to further include a cylindrical object that is housed in the article holding space so that the central axis intersects with the inner bottom sheet, and an accommodation cylinder in which an article to be held is accommodated inside.

[0019] According to this configuration, by providing an accommodation cylinder that is housed in the article holding space, it is possible to hold the article more stably in the storage box.

Mode for Carrying Out the Invention

[0022] Hereinafter, an embodiment of an in-box article holding structure that can stably hold an article in a storage box will be described.

[0023] FIG. 1 is a perspective view showing an in-box article holding structure according to an embodiment together with a storage box.

[0024] The in-box article holding structure 1 shown in FIG. 1 holds, for example, a perishable article such as a cake so as not to move in a storage box 2 for carrying. The storage box 2 in the present embodiment is a cardboard box having a rectangular box shape, and includes a square box bottom wall 21, a square ceiling wall 22, and three rectangular box side walls 23 that connect the sides of the box bottom wall 21 and the ceiling wall 22 to form three of the four side faces. Further, in this storage box 2, the remaining one side face is composed of a pair of left and right doors 24 that can be opened and closed left and right, and a pair of upper and lower doors 25 that can be opened and closed up and down. FIG. 1 shows a state in which these left and right doors 24 and upper and lower doors 25 are opened, one side face is opened, and the in-box article holding structure 1 is accommodated from the opening 2a.

[0025] The in-box article holding structure 1 is a paper product similar to the storage box 2, and is for holding articles such as a one-hole cake inside the rectangular box-shaped storage box 2 so that they do not move. The in-box article holding structure 1 has a structure in which an article holding space 1c for storing articles is constructed on the surface of a substantially square inner bottom sheet 11 corresponding to the box bottom wall 21. This in-box article holding structure 1 is housed in the storage box 2 such that a part of the periphery of the inner bottom sheet 11 abuts against the box side wall 23, whereby the movement inside the storage box 2 is restricted. By this restriction, the in-box article holding structure 1 stores the articles in the article holding space 1c inside the storage box 2 and holds them so that they do not move. In the present embodiment, the in-box article holding structure 1 is composed of two paper products, namely, a holding structure main body 1a and a storage cylinder 1b.

[0026] FIG. 2 is an exploded perspective view of the two-component in-box article holding structure shown in FIG. 1.

[0027] As shown in this FIG. 2, the in-box article holding structure 1 has a configuration in which the storage cylinder 1b is housed in an article holding space 1c constructed on the surface of the inner bottom sheet 11 in the holding structure main body 1a by a combination of four strip-shaped sheets 12. The article holding space 1c constructed by the strip-shaped sheets 12 is a curved rectangular cylindrical space in which each strip-shaped sheet 12 is curved, and the cylindrical storage cylinder 1b is housed therein. The storage cylinder 1b is a cylindrical object that is housed in the article holding space 1c so that its central axis intersects the inner bottom sheet 11, and is a part where the article to be held is housed inside. Articles such as a one-hole cake are housed and held in the article holding space 1c in a state of being housed inside this cylindrical storage cylinder 1b. These holding structure main body 1a and storage cylinder 1b are formed from the following developed shapes.

[0028] FIG. 3 is a view showing the developed shape of the holding structure main body shown in FIG. 2.

[0029] Repeatedly, this holding structure main body 1a includes an inner bottom sheet 11 and four strip-shaped sheets 12.

[0030] The inner bottom sheet 11 is a sheet material that is placed and stored on the bottom wall 21 of the storage box 2. A part of the peripheral edge of this inner bottom sheet 11 abuts against the box side wall 23, thereby restricting movement inside the storage box 2.

[0031] The four strip-shaped sheets 12 are each formed in a strip shape, and one end portion 121a of the long side edge 121 is connected to the peripheral edge of the inner bottom sheet 11 at intervals from each other, forming a spiral arm extending in the turning direction D11 around the central portion 11a of the inner bottom sheet 11. As shown in FIG. 2, these four strip-shaped sheets 12 are folded up with the boundary between one end portion 121a of the long side edge 121 and the inner bottom sheet 11 as a crease 13 and are combined with each other in the turning direction D11 of the spiral arm while being curved. Then, by this combination, the four strip-shaped sheets 12 construct an article holding space 1c having a cylindrical shape around the axis 11b intersecting the inner bottom sheet 11 on the surface of the inner bottom sheet 11 on the vortex center side of each strip-shaped sheet 12.

[0032] Here, in the present embodiment, this inner bottom sheet 11 is formed in a substantially square shape surrounded by four bent edges 111. Each bent edge 111 corresponds one-to-one with four sides 261 forming a quadrangle, specifically a square basic polygon 26 according to the shape of the box bottom wall 21. And the bent edge 111 is composed of two edge portions, a basic edge portion 111a and an angled edge portion 111b. The basic edge portion 111a is an edge portion tracing a part on the downstream side in the turning direction D11 of one side 261 of the basic polygon 26. The angled edge portion 111b is an edge portion inclined at a predetermined inclination angle θ11 with respect to the one side 261 on the upstream side in the turning direction D11 of the one side 261 of the basic polygon 26. The inclination of this angled edge portion 111b is an inward inclination approaching the central portion 11a of the inner bottom sheet 11 as it goes upstream in the turning direction D11, and the inclination angle θ11 is approximately 10° in the present embodiment. The four strip-shaped sheets 12 are connected to the angled edge portions 111b at the respective four bent edges 111 with an interval L11 of a length corresponding to the basic edge portion 111a being opened from each other. This inner bottom sheet 11 is housed in the storage box 2 so that the basic edge portion 111a abuts against the box side wall 23 as shown by the dashed line in FIG. 1.

[0033] Each of the four strip-shaped sheets 12 is formed in a quadrangular strip shape having a long side edge 121 to which one end portion 121a is connected to the inner bottom sheet 11, an opposite side edge 122 on the side opposite to the long side edge 121, an upstream side edge 123, and a downstream side edge 124. The upstream side edge 123 is an edge connecting the two side edges of the long side edge 121 and the opposite side edge 122 on the upstream side in the turning direction D11. Also, the downstream side edge 124 is an edge connecting the two side edges on the downstream side in the turning direction D11. In the present embodiment, the upstream side edge 123 is inclined so as to form an acute angle θ12 with the long side edge 121 and an obtuse angle θ13 with the opposite side edge 122. And the downstream side edge 124 is inclined so as to form an obtuse angle θ14 with the long side edge 121 and an acute angle θ15 with the opposite side edge 122. The four strip-shaped sheets 12 are combined with each other by the following locking structure.

[0034] That is, each strip sheet 12 is provided with a locking portion 125 at the tip of the turning direction D11 at the opposite edge 122 for locking to a locking destination strip sheet 12a adjacent to the downstream side in the turning direction D11. The locking portion 125 is a portion that protrudes hook-shaped with a locking slit 125a sandwiched inside at the tip of the strip sheet 12. On the other hand, a slit 126 for being locked to the locking portion 125 of the locking source strip sheet 12b adjacent to the upstream side in the turning direction D11 is provided near the upstream end of the opposite edge 122 of the strip sheet 12 in the turning direction D11. As schematically shown by the arrow in FIG. 3 and as shown in the locked state in FIG. 2, the locking portion 125 of each strip sheet 12 locks to the slit 126 of the locking destination strip sheet 12a in the downstream locking direction D12. Further, the locking portion 125 of the locking source strip sheet 12b locks to the slit 126 of each strip sheet 12 in the upstream locking direction D13. By such locking, a curved rectangular cylindrical article holding space 1c is formed on the surface of the inner bottom sheet 11. And a cylindrical storage cylinder 1b is stored in this article holding space 1c.

[0035] FIG. 4 is a view showing the developed shape of the storage cylinder shown in FIG. 2.

[0036] As shown in this FIG. 4, the developed shape of the storage cylinder 1b is a rectangular strip-shaped sheet. The storage cylinder 1b is formed by rolling up this rectangular strip-shaped sheet in the longitudinal direction D14 into a cylindrical shape. At this time, the length of the short side 14 in the rectangular strip-shaped sheet becomes the axial height L12 of the storage cylinder 1b as shown in FIG. 2. This height L12 of the storage cylinder 1b is higher than the folding height L13 from the inner bottom sheet 11 when the strip sheet 12 is folded up so that the upper edge side is slightly exposed when stored in the article holding space 1c as shown in FIG. 1.

[0037] Here, in the present embodiment, in the storage cylinder 1b formed by rolling up a rectangular strip-shaped sheet into a cylindrical shape, the two short sides 14 which are the sheet ends in the longitudinal direction D14 are left as free ends without being fixed by fixing members such as adhesive tapes or staplers. And the length of the long side 15 in the rectangular strip-shaped sheet is long enough to maintain the cylindrical shape even when the storage cylinder 1b is housed in the article holding space 1c with the maximum diameter shown in FIGS. 1 and 2 among the four-step draw diameters described later. When the rolled-up storage cylinder 1b is housed in the article holding space 1c, since both ends remain free ends, it expands trying to return to the original rectangular strip shape by the repulsive force, and the cylindrical shape is stabilized by pressing to expand the article holding space 1c from the inside in a cylindrical shape.

[0038] Also, in the present embodiment, four slits 126 are provided at intervals in the longitudinal direction of the opposite edge 122. By changing the positions of the slits 126 for locking the locking portions 125 of the belt-shaped sheets 12, the draw diameter φ11 (FIG. 2) in the turning direction D11 when combining the belt-shaped sheets 12 can be changed in four steps.

[0039] FIG. 5 is a schematic diagram showing three draw diameters of the maximum diameter, the intermediate diameter, and the minimum diameter among the four-step draw diameters.

[0040] In this Figure 5, the holding structure main body 1a with a maximum diameter of φ111 and the in-box article holding structure 1, the holding structure main body 1a with an intermediate diameter of φ112 and the in-box article holding structure 1, and the holding structure main body 1a with a minimum diameter of φ113 and the in-box article holding structure 1 are shown in a top view and a perspective view. The holding structure main body 1a with a maximum diameter of φ111 is configured by locking the locking portion 125 to the slit 126 on the most root side (upstream side) among the four slits 126 of the belt-like sheet 12. The holding structure main body 1a with an intermediate diameter of φ112 is configured by locking the locking portion 125 to any of the two intermediate position slits 126 other than both ends. The holding structure main body 1a with a minimum diameter of φ113 is configured by locking the locking portion 125 to the slit 126 closest to the tip (downstream side). And in the article holding space 1c with each of these aperture diameters, the accommodating cylinder 1b with both ends rounded while remaining free ends is accommodated to form the in-box article holding structure 1. Since both ends of the accommodating cylinder 1b are free ends, it expands by the repulsive force and is pressed against the inner surface so as to fit into the article holding space 1c formed in a curved rectangular cylindrical shape by the belt-like sheet 12, and becomes a cylindrical shape corresponding to each aperture diameter.

[0041] According to the in-box article holding structure 1 of the embodiment described above, the four belt-like sheets 12 are connected to the inner bottom sheet 11 so as to form a spiral arm centering on its central portion 11a. And the article holding space 1c is constructed in a cylindrical shape on the surface of the inner bottom sheet 11 on the vortex center side when the four belt-like sheets 12 are combined with each other in the turning direction D11 of the spiral arm. The article holding space 1c constructed in this way is firmly fixed to the inner bottom sheet 11 at the boundary between the four belt-like sheets 12 and the inner bottom sheet 11. Also, since this article holding space 1c is constructed on the vortex center side away from the connection position with the inner bottom sheet 11 in each belt-like sheet 12, its shape is less likely to be restricted by the connection position. Then, by appropriately adjusting the aperture diameter φ11 in the turning direction D11 when combining the four belt-like sheets 12 in the turning direction D11 of the spiral arm according to the size of the article, the gap with the article can be suppressed to construct the cylindrical article holding space 1c. Thus, according to the above-described in-box article holding structure, since the article holding space 1c with less restriction on the connection position and the gap with the article suppressed is firmly fixed to the inner bottom sheet 11, the article can be stably held in the storage box 2.

[0042] Here, in the present embodiment, the inner bottom sheet 11 has a shape surrounded by four bending edges 111 based on a basic polygon 26 corresponding to the square shape of the bottom wall 21 of the storage box 2, and each strip sheet 12 is connected to the angled edge portion 111b of each bending edge 111. According to this configuration, each strip sheet 12 is connected to the angled edge portion 111b that is inclined so as to approach the central portion 11a of the inner bottom sheet 11 toward the upstream in the turning direction D11 at each bending edge 111. As a result, when the cylindrical article holding space 1c is constructed in combination with the turning direction D11, a repulsive force in the direction away from the central portion 11a of the inner bottom sheet 11 strongly acts on the connecting portion of one strip sheet 12 with the adjacent strip sheet 12. As a result, the connection strength between the strip sheets 12 is strengthened by the above repulsive force, and the shape of the article holding space 1c can be stably maintained.

[0043] Further, in the present embodiment, the basic polygon 26 is a quadrilateral, specifically a square, the inner bottom sheet 11 has a shape surrounded by four bending edges 111, and four strip sheets 12 connected to the angled edge portions 111b of the respective bending edges 111 are provided. According to this configuration, since the article holding space 1c is constructed by the four strip sheets 12, an excessive load applied from all directions to the article holding space 1c can be evenly supported by the four strip sheets 12, and the article can be held more stably.

[0044] Further, in the present embodiment, a locking portion 125 is provided at the tip (downstream side) in the turning direction D11 of each strip sheet 12, and a slit 126 is provided on the opposite side (upstream side). According to this configuration, by locking the locking portion 125 to the slit 126, the article holding space 1c can be easily constructed by combining the strip sheets 12 compared with the case of using a fixing member such as an adhesive tape or a stapler.

[0045] In addition, in the present embodiment, a plurality of slits 126, specifically four slits, are provided. According to this configuration, by changing the positions of the slits 126 to be latched, the aperture diameter φ11 in the turning direction D11 when combining the belt-like sheets 12 can be changed, and an article holding space 1c with an optimal diameter according to the size of the article can be easily constructed.

[0046] In addition, in the present embodiment, a storage cylinder 1b to be housed in the article holding space 1c is provided. According to this configuration, by providing the storage cylinder 1b to be housed in the article holding space 1c, the article can be held more stably in the storage box 2.

[0047] In addition, in the present embodiment, the storage cylinder 1b is formed by rolling a belt-like sheet into a cylindrical shape. According to this configuration, the rolled sheet expands by its repulsive force and presses the article holding space 1c from the inside, so that the shape of the storage cylinder 1b can be stabilized in a cylindrical shape regardless of the size of the article holding space 1c.

[0048] In addition, in the present embodiment, each belt-like sheet 12 is formed in a quadrangular belt shape having a long side edge 121 on the inner bottom sheet 11 side, an opposite edge 122, an inclined upstream edge 123, and an inclined downstream edge 124. According to this configuration, since the downstream side in the turning direction D11 of each belt-like sheet 12 has an acute-angled shape, it is tapered and easily curved, and the article holding space 1c can be constructed with good workability. Also, on the upstream side in the turning direction D11 of each belt-like sheet 12, since the upstream edge 123 rises obliquely from the inner bottom sheet 11, an extra protruding portion from the article holding space 1c on this upstream side can be suppressed. As a result, the interference between the two when housing the in-box article holding structure 1 in the storage box 2 can be suppressed, and the housing operation into the storage box 2 can be performed with good workability.

[0049] With the above, the description of the embodiment with reference to FIGS. 1 to 5 is completed. Hereinafter, two modification examples of this embodiment will be described. In both of these two modification examples, the shape of the holding structure main body is different from that of the above-described embodiment. Hereinafter, the holding structure main body in each modification example will be described using the developed shape in which the difference from the embodiment is most easily understood.

[0050] FIG. 6 is a view showing the holding structure main body of the first modification example with respect to the embodiment shown in FIGS. 1 to 5 in a developed shape.

[0051] In this first modification example, the shape of the inner bottom sheet 31 of the holding structure main body 3a is different from that of the above-described embodiment. On the other hand, the components other than the inner bottom sheet 31 are equivalent to the components in FIG. 3. In FIG. 6, the same reference numerals as those in FIG. 3 are given to these equivalent components, and hereinafter, the overlapping description of these equivalent components will be omitted.

[0052] In the first modification example, the inner bottom sheet 31 has a polygon, specifically a square shape, corresponding to the shape of the bottom wall 21 of the storage box 2 shown in FIG. 1. The four strip-shaped sheets 12 are connected to a part 311b on the upstream side in the turning direction D11 at each of the four edges 311 of the square inner bottom sheet 31, with an interval L31 of a length corresponding to the other part 311a at each edge 311 being opened from each other.

[0053] Needless to say, also in the first modification example described above, the article can be stably held in the storage box 2 in the same manner as in the above-described embodiment.

[0054] Also, in the first modification example, the inner bottom sheet 31 is a square corresponding to the shape of the bottom wall 21, and the strip-shaped sheet 12 is connected to a part 311b on the upstream side in the turning direction D11 at each edge 311. According to this configuration, since the in-box article holding structure is housed in the storage box 2 so that substantially all of the peripheral edge of the inner bottom sheet 31 abuts against the box side wall 23, the article can be held more stably in the storage box 2.

[0055] FIG. 7 is a view showing the holding structure main body of the second modification for the embodiment shown in FIGS. 1 to 5 in a developed shape. In FIG. 7, similar to FIG. 6 described above, the same reference numerals as those in FIG. 3 are given to the components equivalent to those in the embodiment except for the inner bottom sheet 41 having a shape different from that of the above-described embodiment, and hereinafter, duplicate explanations of these equivalent components will be omitted.

[0056] In the holding structure main body 4a of this second modification, the inner bottom sheet 41 is, in detail, formed in a shape surrounded by three bending edges 411 based on an equilateral triangle as the basic polygon 56. Each bending edge 411 has a basic edge portion 411a tracing a part on the downstream side in the turning direction D41 of one side 561 of the basic polygon 56, and an angled edge portion 411b inclined inward at an inclination angle θ41 of approximately 10° with respect to the one side 561. And three strip-shaped sheets 12 are connected to the angled edge portions 411b at each of the three bending edges 411 with an interval L41 having a length corresponding to the basic edge portion 411a being opened from each other.

[0057] In the second modification, the inner bottom sheet 41 is formed in a substantially triangular shape, and one vertex which is a part of the peripheral edge is provided on the box side wall 23 of the storage box 2 shown in FIG. 1, and the movement inside the storage box 2 is restricted by abutting against one basic edge portion 411a. Alternatively, for example, the movement inside the box may be restricted by abutting against two basic edge portions 411a on the box side wall of a storage box having a triangular prism shape.

[0058] Needless to say, in the second modification described above as well, the article can be stably held in the storage box 2 in the same manner as in the above-described embodiment.

[0059] Note that the above-described embodiments and modifications merely show typical forms, and the in-box article holding structure is not limited to these embodiments. That is, those skilled in the art can implement various modifications in accordance with conventionally known knowledge.

[0060] For example, in the above-described embodiments and modified examples, as an example of the in-box article holding structure, an in-box article holding structure 1 that holds a columnar article such as a one-hole cake in a substantially cylindrical article holding space 1c is illustrated. However, the in-box article holding structure is not limited to this, and it may hold articles other than cakes, and the shapes of the article and the article holding space may also be shapes other than columnar and substantially cylindrical. For example, it may be one that holds a rectangular block-shaped article in a curved rectangular cylindrical article holding space, and the specific article shape and the cylindrical shape of the article holding space can be set as appropriate.

[0061] Also, in the above-described embodiments and modified examples, as an example of the storage box in which the in-box article holding structure is housed, a storage box 2 having a rectangular box shape and having one side open and housing the in-box article holding structure 1 is illustrated. However, as mentioned in the second modified example, the shape of the storage box is not limited to such a shape. The shape of the storage box can be set as appropriate according to the use as long as the inner bottom sheet of the in-box article holding structure abuts against the box side wall at a part of its periphery and the movement inside the box is restricted. Also, the storage opening of the in-box article holding structure is not limited to the side surface, and for example, the upper surface may be open and the in-box article holding structure may be housed from above.

[0062] Also, in the above-described embodiments and modified examples, as an example of each of the storage box and the in-box article holding structure, a paper-made storage box 2 and an in-box article holding structure 1 are illustrated. However, the storage box and the in-box article holding structure are not limited to being made of paper, and for example, the in-box article holding structure may be formed of a thin resin sheet or the like that can be folded up a strip-shaped sheet with respect to the inner bottom sheet.

[0063] Further, in the above-described embodiments and the second modification example, as an example of the in-box article holding structure, an in-box article holding structure in which the belt-like sheet 12 is connected to the angled edge portions 111b and 411b of the angled edges 111 and 411 is illustrated. However, the in-box article holding structure is not limited to these. For example, as illustrated in the first modification example, the belt-like sheet 12 may be connected to each edge of the inner bottom sheet 31 surrounded by straight edges that are not bent. However, according to the configuration in which the belt-like sheet 12 is connected to the angled edge portions 111b and 411b of the angled edges 111 and 411, the connection strength between the belt-like sheets 12 is enhanced, and the shape of the article holding space 1c can be stably maintained, as described above. Incidentally, even when adopting the configuration in which the belt-like sheet 12 is connected to the angled edge portions 111b and 411b of the angled edges 111 and 411, the shape of the inner bottom sheet is not limited to a substantially quadrangular or substantially triangular shape, and the number of belt-like sheets is not limited to four or three. The shape of the inner bottom sheet and the number of belt-like sheets can be appropriately set according to the shape of the storage box and the like.

[0064] Further, in the above-described embodiment, as an example of the in-box article holding structure, an in-box article holding structure 1 including an inner bottom sheet 11 surrounded by four bent edges 111 based on a quadrangular basic polygon 26 and four belt-like sheets 12 is illustrated. However, as illustrated in the first and second modification examples, it may be one including an inner bottom sheet 31 surrounded by straight edges that are not bent, or one including an inner bottom sheet 41 surrounded by three bent edges 411 based on a triangular basic polygon 56. However, according to the in-box article holding structure 1 including the inner bottom sheet 11 based on the quadrangular basic polygon 26 and the four belt-like sheets 12 connected thereto, the point that the overload from all directions can be supported well in balance and the article can be held more stably is as described above.

[0065] In addition, in the above-described first modification example, as an example of the in-box article holding structure, an in-box article holding structure in which the strip-shaped sheet 12 is connected to the straight edge 311 of the square inner bottom sheet 31 is illustrated. However, as illustrated in the embodiment and the second modification example, the in-box article holding structure is not limited to this, and the strip-shaped sheet 12 may be connected to the angled edge portions 111b and 411b of the bent edges 111 and 411. However, according to the structure in which the strip-shaped sheet 12 is connected to the straight edge 311 of the inner bottom sheet 31, as described above, substantially all of the peripheral edge of the inner bottom sheet 31 can be brought into contact with the box side wall 23 of the storage box 2 to more stably hold the article.

[0066] In addition, in the above-described embodiment and modification examples, the in-box article holding structure 1 in which the locking portion 125 and the slit 126 are provided in each strip-shaped sheet 12 is illustrated. However, the in-box article holding structure is not limited to this, and the strip-shaped sheets may be fixed and combined with each other by fixing members such as adhesive tapes and staplers without providing locking means such as locking portions and slits in each strip-shaped sheet. However, as described above, by providing the locking portion 125 and the slit 126 in the strip-shaped sheet 12, the strip-shaped sheets 12 can be easily combined to construct the article holding space 1c.

[0067] In addition, in the above-described embodiment and modification examples, as an example of the slit provided in the strip-shaped sheet, the four slits 126 provided in the strip-shaped sheet 12 are illustrated. However, the number of slits in the strip-shaped sheet is not limited to a plurality such as four, and only one slit may be provided. However, as described above, by providing a plurality of slits 126 in the strip-shaped sheet 12, the optimum diameter article holding space 1c can be easily constructed according to the size of the article. Note that even when a plurality of slits are provided, the number is not limited to four, and a number of slits other than four may be provided in the strip-shaped sheet.

[0068] In addition, in the above-described embodiments and modified examples, as an example of the in-box article holding structure, the in-box article holding structure 1 including the storage cylinder 1b stored in the article holding space 1c is illustrated. However, the in-box article holding structure is not limited to this, and it may be configured without providing any storage cylinder. However, as described above, by providing the storage cylinder 1b, the article can be held more stably in the storage box 2.

[0069] In addition, in the above-described embodiments and modified examples, as an example of the storage cylinder, the storage cylinder 1b formed by rolling a belt-like sheet into a cylindrical shape is illustrated. However, the storage cylinder is not limited to this, and any structure having a cylindrical structure stored in the article holding space may be used, such as a resin cylinder or a metal cylinder that is initially formed in a cylindrical shape. Further, the shape may not be cylindrical, but may be square cylindrical or the like. However, according to the storage cylinder 1b formed by rolling a belt-like sheet into a cylindrical shape, as described above, the shape of the storage cylinder 1b can be stabilized into a cylindrical shape regardless of the size of the article holding space 1c.

[0070] In addition, in the above-described embodiments and modified examples, as an example of the belt-like sheet, the belt-like sheet 12 formed in a rectangular belt shape having an inclined upstream edge 123 and a downstream edge 124 is illustrated. However, the belt-like sheet is not limited to this, and its shape can be arbitrarily set. However, according to the belt-like sheet 12 having the inclined upstream edge 123 and the downstream edge 124, the article holding space 1c can be constructed with good workability, and the in-box article holding structure 1 can be stored with good workability while suppressing interference with the storage box 2, as described above.
