Summary of the Invention

Problems to be Solved by the Invention

[0006] By the way, from the viewpoint of resource saving, it is desired to efficiently form a storage box from a die-cut paper punched from a sheet material.

[0007] For example, in the box described in Patent Document 1, the first right side panel, which is part of the components constituting the left cylindrical body, and the second left side panel, which is part of the components constituting the right cylindrical body, are arranged in an overlapping manner. The box uses the overlapping first right side panel and the second left side panel as a partition to separate the storage area for the left cylindrical body from the storage area for the right cylindrical body. Therefore, in the box described in Patent Document 1, from the viewpoint of resource conservation, it is desirable to eliminate the overlapping state of the side panels of the two cylindrical bodies described above in order to save sheet material.

[0008] The objective of this invention is to provide a storage box that allows for sorting and storing items, and that saves on materials such as sheet material. [Means for solving the problem]

[0009] The inventors of this invention studied a storage box that could sort and store items while also saving on materials such as sheet material. After diligent study, the inventors came up with the following configuration.

[0010] An embodiment of the present invention is a storage box formed by folding a single sheet material and having a first box body and a second box body. The storage box has a common wall member, the first box body is formed on one side of the common wall member such that a part of the common wall member constitutes a part of the first box body, and the second box body is formed on the other side of the common wall member such that a part of the common wall member constitutes a part of the second box body.

[0011] In the configuration described above, a portion of the first box and a portion of the second box are each made up of a portion of the common wall member. Furthermore, the first box and the second box are positioned on one side and the other side of the common wall member, respectively. Therefore, when viewed in a direction perpendicular to the common wall member, if at least a portion of the first box and at least a portion of the second box overlap, the overlapping portions of the first and second boxes are made up of a single wall member.

[0012] Thus, the storage box is constructed as a single structure including a first box body and a second box body, with a common wall member acting as a partition. Therefore, compared to joining the wall members of the first box body and the wall members of the second box body, which are each formed from separate or the same sheet material, sheet material or adhesive for forming the wall members or adhesive gaps of the first and second box bodies can be saved.

[0013] Furthermore, in the above configuration, the storage box has two independent storage compartments separated by a common wall member. Therefore, it is possible to sort and store items in the first and second box bodies of the storage box. Thus, it is possible to provide a storage box that allows for sorted storage of items and saves on materials such as sheet material.

[0014] Furthermore, the first and second boxes are positioned on one and the other sides of a common wall member, respectively. Therefore, since the first and second boxes are positioned in a way that they do not interfere with each other, their position, size, and shape relative to the common wall member can be arbitrarily set. In this way, the storage boxes can be flexibly adapted to the shape of the stored items and the stacking arrangement of the storage boxes.

[0015] From another perspective, the storage box of the present invention preferably includes the following configuration: At least a portion of the first box body and at least a portion of the second box body overlap when viewed in a direction perpendicular to the common wall member.

[0016] In the above configuration, at least one of the first and second box bodies is positioned perpendicular to the surface of the common wall member. In other words, the storage box does not have any parts composed solely of the common wall member. Therefore, the storage box improves the Young's modulus in the direction perpendicular to the surface of the common wall member through the storage sections of the first and second box bodies. That is, the first and second box bodies function as structural members that maintain the rigidity of the entire storage box. As a result, the rigidity of the entire storage box can be improved and resources can be saved compared to the case where the first and second box bodies do not overlap when viewed perpendicular to the surface of the common wall member.

[0017] From another perspective, the storage box of the present invention preferably includes the following configuration: When viewed in a direction perpendicular to the common wall member, the first box body and the second box body overlap in a partially offset manner.

[0018] According to the above configuration, a storage box is obtained in which the first and second boxes are stacked in a stepped manner. Therefore, even though the first and second boxes are formed by folding a single sheet material, it can be imagined as two independent boxes joined together. Furthermore, when the first and second storage boxes are placed next to each other, for example, the second box of the second storage box can be stacked on top of the first box of the first storage box. In this way, since the boxes of adjacent storage boxes are stacked on either the first or second box, the orientation of multiple storage boxes is stable when they are placed side by side.

[0019] From another perspective, the storage box of the present invention preferably includes the following configuration: Each wall constituting the side surface of the first box body is formed by folding a sheet material in one direction in the thickness direction of the common wall member, and each wall constituting the side surface of the second box body is formed by folding a sheet material in the other direction in the thickness direction of the common wall member.

[0020] In the above configuration, by bending both ends of a common wall member in a direction perpendicular to the surface, a first box body is formed on one side of the common wall member, and a second box body is formed on the other side. Therefore, by constructing the first and second box bodies based on a common wall member, it is possible to provide a storage box that allows for sorting and storing items with a simple configuration, and that saves on materials such as sheet material.

[0021] From another perspective, it is preferable that the storage box of the present invention includes the following configuration. The first box body and the second box body are cylindrical members that are at least partially polygonal when viewed in the axial direction. According to such a configuration, since the storage boxes are arranged adjacent to each other with the planes of the first box body or the second box body, which are cylindrical members having at least a plurality of planes, in contact with the planes of the box bodies of other storage boxes, the placement state is more stable.

[0022] From another perspective, it is preferable that the storage box of the present invention includes the following configuration. The first box body and the second box body are rectangular cylindrical members when viewed in the axial direction. According to such a configuration, a storage box that is rectangular or stepped when viewed in the direction in which the cylinder extends can be obtained. Therefore, since the storage boxes are arranged adjacent to each other with the planes of the first box body or the second box body, which are quadrangular prism-shaped, in contact with the planes of the quadrangular prism-shaped box bodies of other storage boxes, the placement state is more stable.

[0023] From another perspective, it is preferable that the storage box of the present invention includes the following configuration. At least one of the first box body and the second box body has a support portion inside. According to such a configuration, the storage space of the first box body or the second box body having the support portion can be further divided. In addition, the rigidity of the first box body or the second box body having the support portion is improved. Further, when the storage box has support portions in the first box body and the second box body respectively, the closer the support portion of the first box body is to the support portion of the second box body, the more the rigidity of not only the first box body and the second box body but also the entire storage box can be improved.

[0030] The storage box according to the present invention will be described below with reference to the drawings. In each drawing, the same parts are denoted by the same reference numerals, and the description of the same parts will not be repeated. The dimensions of the components in each drawing do not faithfully represent the dimensions of the actual components or the dimensional ratios of each component.

The arrow UP in the figure indicates the upward direction in the height direction of storage box 1. The arrow DW in the figure indicates the downward direction in the height direction of storage box 1. The depth direction, width direction, and height direction are orthogonal to each other.

[0032] Furthermore, the depth, width, and height of storage box 1 coincide with the depth, width, and height of the first box body 10 and the second box body 20, respectively.

[0033] <Overall Structure> A storage box 1, an embodiment of the present invention, will be described using Figures 1 to 3. Figure 1 is a perspective view of the storage box 1 in the embodiment of the present invention with the lid closed. Figure 2 is a perspective view of the storage box 1 in the embodiment of the present invention with the lid open. Figure 3 is an enlarged cross-sectional view taken along the line III-III in Figure 1.

[0034] As shown in Figures 1 to 3, the storage box 1 is a paper box formed by folding a single sheet of material. The storage box 1 has a wall member 30 common to the first box body 10 and the second box body 20. The first box body 10 and the second box body 20 are each cylindrical in shape, extending in the height direction. Furthermore, the first box body 10 and the second box body 20 are rectangular when viewed in the depth direction, width direction, and height direction. When viewed in the depth direction, the first box body 10 and the second box body 20 overlap with a portion offset in the width direction.

[0035] The first box 10 has a side wall portion 11 that forms a cylindrical shape, a lid portion 12 located at the upper end of the side wall portion 11 in the height direction, and a bottom portion 13 located at the lower end of the side wall portion 11 in the height direction. In addition, as shown in Figures 2 and 3, the first box 10 has a support portion 51 inside.

[0036] The side wall portion 11 has a first side wall portion 111, a second side wall portion 112, a third side wall portion 113, and a fourth side wall portion 114.

[0037] The first side wall portion 111 constitutes the front of the first box body 10. The second side wall portion 112 constitutes the right side of the first box body 10. The third side wall portion 113 constitutes the left side of the first box body 10. The fourth side wall portion 114 constitutes the rear of the first box body 10.

[0038] The lid 12 is connected to the upper end of the fourth side wall 114 in the height direction. The lid 12 is rotatable upward around the connection point with the fourth side wall 114. By rotating the lid 12 from the closed state shown in Figure 1, the lid 12 can be switched to the open state shown in Figure 2. With the lid 12 open, items can be stored inside the first box body 10. The bottom 13 has the same configuration as the lid 12 except that it is connected to the lower end of the fourth side wall 114 in the height direction, so its description will not be repeated here.

[0039] The support portion 51 supports the first side wall portion 111 with respect to the fourth side wall portion 114. The support portion 51 divides the inside of the first box 10 into a first space SP11 and a second space SP12 in the width direction. The support portion 51 is located to the right of the center in the width direction of the first box 10. Therefore, the second space SP12 inside the first box 10 can accommodate relatively small items that are stored in the first space SP11.

[0040] The second box 20 has a side wall portion 21 that forms a cylindrical shape, a lid portion 22 located at the upper end of the side wall portion 21 in the height direction, and a bottom portion 23 located at the lower end of the side wall portion 21 in the height direction. In addition, as shown in Figures 2 and 3, the second box 20 has a support portion 61 inside.

[0041] The side wall portion 21 has a first side wall portion 211, a second side wall portion 212, a third side wall portion 213, and a fourth side wall portion 214.

[0042] The first side wall portion 211 constitutes the front surface of the second box body 20. The second side wall portion 212 constitutes the right side surface of the second box body 20. The third side wall portion 213 constitutes the left side surface of the second box body 20. The fourth side wall portion 214 constitutes the rear surface of the second box body 20.

[0043] The lid portion 22 is connected to the upper end of the fourth side wall portion 214 in the height direction. The lid portion 22 is rotatable upward around the connection point with the fourth side wall portion 214. By rotating the lid portion 22 from the closed state shown in Figure 1, the lid portion 22 can be switched to the open state shown in Figure 2. With the lid portion 22 open, items can be stored inside the second box body 20. The bottom portion 23 has the same configuration as the lid portion 22 except that it is connected to the lower end of the fourth side wall portion 214 in the height direction, so its description will not be repeated here.

[0044] The support portion 61 supports the fourth side wall portion 214 relative to the first side wall portion 211. The support portion 61 divides the inside of the second box 20 into a first space SP21 and a second space SP22 in the width direction. The support portion 61 of the second box 20 is located to the right of the center of the second box 20 in the width direction. Therefore, smaller items can be neatly stored in the second space SP22 inside the second box 20 compared to the items stored in the first space SP21.

[0045] The width of the second space SP12 in the first box 10 and the width of the second space SP22 in the second box 20 are the same. The effects of this configuration will be described later.

[0046] As shown in Figure 3, the common wall member 30 constitutes a part of the first box body 10 and a part of the second box body 20. The common wall member 30 is a wall member that constitutes the fourth side wall portion 114 and the first side wall portion 211. In the common wall member 30, the first portion 31, the second portion 32, and the third portion 33 are positioned in order from one side to the other in the width direction.

[0047] The first part 31 is the portion of the common wall member 30 that constitutes only the fourth side wall portion 114. The second part 32 is the portion of the common wall member 30 that overlaps with the fourth side wall portion 114 when viewed in a direction perpendicular to the surface of the common wall member 30. The third part 33 is the portion of the common wall member 30 that constitutes only the first side wall portion 211.

[0048] The fourth side wall portion 114 of the first box body 10 is composed of a first portion 31 and a second portion 32 of a common wall member 30. The first side wall portion 211 of the second box body 20 is composed of a second portion 32 and a third portion 33 of the common wall member 30. In addition, a part of the fourth side wall portion 114 is common with a part of the first side wall portion 211. In other words, a part of the fourth side wall portion 114 and the first side wall portion 211 share the second portion 32 of the common wall member 30, which is a single wall member.

[0049] The first box body 10 is formed on the front side, which is one side in the thickness direction of the common wall member 30. The second box body 20 is formed on the back side, which is the other side in the thickness direction of the common wall member 30.

[0050] <Blank storage box> Figure 4 will be used to explain the blank BL1 used in assembling the storage box 1. Figure 4 is a plan view of the blank BL1 used to form the storage box.

[0051] As shown in Figure 4, the blank BL1 of the storage box 1 is a sheet material formed, for example, by punching out the outer edge shape of cardboard and folding it. In Figure 4, mountain folds are indicated by dashed lines, and valley folds are indicated by dotted lines.

[0052] Blank BL1 has a first enclosure-specific part BL10, a common part BL30, and a second enclosure-specific part BL20. In Blank BL1, the first enclosure-specific part BL10, the common part BL30, and the second enclosure-specific part BL20 are connected in order.

[0053] In the first box-shaped section BL10, the support section forming piece BL51, the third side wall forming piece BL113, the first side wall forming piece BL111, and the second side wall forming piece BL112 are connected in order from one end to the other along the length of the blank BL1. The width of the first box-shaped section 10 can be adjusted by the length of the first side wall forming piece BL111. The depth of the first box-shaped section 10 can be adjusted by the length of the third side wall forming piece BL113. The height of the first box-shaped section 10 can be adjusted by the widths of the first side wall forming piece BL111 and the third side wall forming piece BL113.

[0054] The support portion forming piece BL51 has a first adhesive portion BL511 and a second adhesive portion BL512. The first adhesive portion BL511 is located at one end of the support portion forming piece BL51 in the longitudinal direction of the blank BL1. The second adhesive portion BL512 is located at the other end of the support portion forming piece BL51 in the longitudinal direction of the blank BL1. The position of the support portion 51 relative to the common wall member 30 can be adjusted by the length of the second adhesive portion BL512.

[0055] The common section BL30 is connected to the other end of the first box-specific section BL10 at one end in the longitudinal direction of the blank BL1. The common section BL30 includes a common wall forming piece BL130, a lid forming piece BL12, and a bottom forming piece BL13.

[0056] The common wall forming piece BL130 is a piece for forming a common wall member 30. The common wall forming piece BL130 is connected at one end in the longitudinal direction of the blank BL1 to the other end of the second side wall forming piece BL112.

[0057] The lid-forming piece BL12 is a piece for forming the lid 12 of the first box body 10. In the width direction of the blank BL1, one end of the lid-forming piece BL12 is connected to the other end of the common wall-forming piece BL130.

[0058] The bottom forming piece BL13 is a piece for forming the bottom 13 of the first box body 10. In the width direction of the blank BL1, the other end of the bottom forming piece BL13 is connected to one end of the common wall forming piece BL130.

[0059] The second box-specific part BL20 is connected to the other end of the common part BL30 at one end in the longitudinal direction of the blank BL1. In the second box-specific part BL20, the second side wall forming piece BL212, the fourth side wall forming piece BL214, the third side wall forming piece BL213, and the support forming piece BL61 are connected in order from one end to the other in the longitudinal direction of the blank BL1. The width of the second box-specific part 20 can be adjusted by the length of the fourth side wall forming piece BL214. The depth of the second box-specific part 20 can be adjusted by the length of the third side wall forming piece BL213. The height of the second box-specific part 20 can be adjusted by the widths of the fourth side wall forming piece BL214 and the third side wall forming piece BL213.

[0060] The fourth side wall forming piece BL214 has a lid forming piece BL22 connected to one end in the width direction, and a bottom forming piece BL23 connected to the other end in the width direction.

[0061] The support portion forming piece BL61 has a first adhesive portion BL611 and a second adhesive portion BL612. The first adhesive portion BL611 is located at the other end of the support portion forming piece BL61 in the longitudinal direction. The second adhesive portion BL612 is located at one end of the support portion forming piece BL61 in the longitudinal direction. The position of the support portion 61 relative to the common wall member 30 can be adjusted by the length of the second adhesive portion BL612.

[0062] <Storage box assembly process> An example of the assembly process for storage box 1 will be explained using Figures 5 to 7. Figure 5 is a perspective view showing part of the assembly process in which blank BL1 is folded to create the storage box. Figure 6 is a perspective view showing another part of the assembly process in which blank BL1 is folded to create the storage box. Figure 7 is a perspective view showing yet another part of the assembly process in which blank BL1 is folded to create the storage box.

[0063] In the assembly process of the storage box 1, first, as shown in Figure 5, the first box-specific part BL10 is bent in one direction in the thickness direction at one end of the common part BL30 in the length direction of the blank BL1, and the second box-specific part BL20 is bent in the other direction in the thickness direction at the other end of the common part BL30 in the length direction.

[0064] Next, as shown in Figure 6, the first box-specific portion BL10 and the second box-specific portion BL20 of the blank BL1, which are in the process of being folded, are further folded. Specifically, in the first box-specific portion BL10, the support portion forming piece BL51 shown in Figure 4, the third side wall portion forming piece BL113, the first side wall portion forming piece BL111, and the second side wall portion forming piece BL112 are folded in a valley fold at their respective connecting portions. In addition, one side in the thickness direction of the first adhesive portion BL511 of the support portion forming piece BL51 is bonded while overlapping with one side in the thickness direction of the first side wall portion forming piece BL111. The other side in the thickness direction of the second adhesive portion BL512 of the support portion forming piece BL51 is bonded while overlapping with one side in the thickness direction of the common portion BL30.

[0065] Furthermore, in the second box-specific part BL20, the second side wall forming piece BL212, the fourth side wall forming piece BL214, the third side wall forming piece BL213, and the support part forming piece BL61, as shown in Figure 4, are folded in a mountain fold at their respective connecting portions. The other side in the thickness direction of the first adhesive portion BL611 of the support part forming piece BL61 is bonded to the other side in the thickness direction of the fourth side wall forming piece BL214 while overlapping it. The one side in the thickness direction of the second adhesive portion BL612 of the support part forming piece BL61 is bonded to the other side in the thickness direction of the common part BL30 while overlapping it.

[0066] Note that in Figure 6, the notation for mountain folds and valley folds is reversed between one side and the other side in the thickness direction of the blank BL1 during the folding process. That is, in Figure 6, the valley folds on one side in the thickness direction of the blank BL1, which are shown with dashed lines in Figure 5, are shown as mountain folds with dashed lines on the other side in the thickness direction of the blank BL1 visible in Figure 6. The reverse is also true.

[0067] Through the above process, a workpiece WK1 is obtained in which the side wall portion 11 of the first box body 10 and the side wall portion 21 of the second box body 20 are formed, as shown in Figure 7. By folding the lid-forming piece BL12 and the bottom-forming piece BL13, the lid portion 12 and the bottom portion 13 of the first box body 10 are formed, respectively. Similarly, by folding the lid-forming piece BL22 and the bottom-forming piece BL23, the lid portion 22 and the bottom portion 23 of the second box body 20 are formed, respectively. This completes the assembly of the storage box 1 as shown in Figure 1, etc. In this way, by simply folding a single sheet material in one direction and the other direction with respect to the common portion BL30, two storage portions and support portions 51, 61 can be constructed without overlapping wall members 30.

[0068] As described above, the storage box 1 is formed by folding a single sheet material and has a first box body 10 and a second box body 20. The storage box 1 has a common wall member 30. The first box body 10 is formed on one side of the common wall member 30 such that a part of the common wall member 30 constitutes a part of the wall member of the first box body 10. The second box body 20 is formed on the other side of the common wall member 30 such that a part of the common wall member 30 constitutes a part of the wall member of the second box body 20.

[0069] In the above configuration, a portion of the wall member of the first box 10 and a portion of the wall member of the second box 20 are each made up of a portion of the common wall member 30. Furthermore, the first box 10 and the second box 20 are positioned on one side and the other side of the common wall member 30, respectively. Therefore, when viewed in the depth direction perpendicular to the common wall member 30, the overlapping portions of the first box 10 and the second box 20 can be made up of a single wall member.

[0070] Thus, the storage box 1 is configured as a single structure including a first box body 10 and a second box body 20, with a common wall member 30 acting as a partition member. Therefore, compared to joining the wall members of the first box body 10 and the wall members of the second box body 20, which are formed from separate sheet materials or the same sheet material, sheet material or adhesive for forming the wall members or adhesive gaps of the first box body 10 and the second box body 20 can be saved.

[0071] Furthermore, in the above configuration, the storage box 1 has two independent storage compartments separated by a common wall member 30. Therefore, the storage box 1 can also store items separately in the first box body 10 and the second box body 20. Thus, it is possible to provide a storage box 1 that allows for the separate storage of items and saves on materials such as sheet material.

[0072] The first box 10 and the second box 20 are positioned on one side and the other side of the common wall member 30, respectively. Therefore, since the first box 10 and the second box 20 are in a positional relationship that does not interfere with each other, their position, size, and shape relative to the common wall member 30 can be arbitrarily set. In this way, the storage box 1 can flexibly adapt to the shape of the stored items and the state in which the storage boxes 1 are stacked.

[0073] Furthermore, in storage box 1, at least a portion of the first box body 10 and at least a portion of the second box body 20 overlap when viewed in the depth direction, which is perpendicular to the common wall member 30.

[0074] In the above configuration, the common wall member 30 is arranged such that at least one of the first box body 10 and the second box body 20 is positioned in the depth direction perpendicular to the surface of the common wall member 30. In other words, the storage box 1 does not have any part composed solely of the common wall member 30. Therefore, the storage box 1 improves the Young's modulus in the depth direction perpendicular to the surface of the common wall member 30 through the storage sections of the first box body 10 and the second box body 20. That is, the first box body 10 and the second box body 20 function as structural members that maintain the overall rigidity of the storage box 1. As a result, the overall rigidity of the storage box 1 can be improved and resources can be saved compared to the case where the first box body 10 and the second box body 20 do not overlap when viewed in the depth direction perpendicular to the surface of the common wall member 30.

[0075] Furthermore, in storage box 1, when viewed in a direction perpendicular to the common wall member 30, the first box body 10 and the second box body 20 overlap with a partial misalignment.

[0076] This results in a storage box 1 in which the first box body 10 and the second box body 20 are stacked in a stepped manner. Thus, even though the first box body 10 and the second box body 20 are formed by folding a single sheet material, it can be imagined as two independent boxes joined together. Furthermore, when the first and second storage boxes are placed next to each other, for example, the second box body 20 of the second storage box can be stacked on the first box body 10 of the first storage box. In this way, since the box body of the adjacent storage box is stacked on either the first box body 10 or the second box body 20 of the storage box 1, the orientation of multiple storage boxes 1 when placed side by side is stable.

[0077] Furthermore, in the storage box 1, each wall constituting the side of the first box body 10 is formed by folding a sheet material in one direction in the thickness direction at one end in the width direction, which is one direction of the common wall member 30. Similarly, each wall constituting the side of the second box body 20 is formed by folding a sheet material in the other direction in the thickness direction at the other end in the width direction, which is the other direction of the common wall member 30.

[0078] In the above configuration, by bending both ends of the common wall member 30 in a direction perpendicular to the surface, the first box body 10 is formed on one side of the common wall member 30 and the second box body 20 is formed on the other side. Therefore, by configuring the first box body 10 and the second box body 20 with the common wall member 30 as a reference, it is possible to provide a storage box 1 that allows for sorting and storing items with a simple configuration and saves on materials such as sheet material.

[0079] Furthermore, the first and second boxes are cylindrical members with a rectangular shape when viewed in the axial direction. With this configuration, a rectangular or stepped storage box is obtained when viewed in the direction in which the cylinder extends. Therefore, adjacent storage boxes 1 are arranged so that the plane of the rectangular prism-shaped first box 10 or second box 20 is in contact with the plane of the rectangular prism-shaped box of the other storage box 1, resulting in a more stable placement. In this way, the placement of the storage boxes 1 is stable, so even when heavy items are stored inside the storage boxes 1, a stable state can be maintained.

[0080] The first box 10 has an internal support section 51, and the second box 20 has an internal support section 61. With this configuration, the storage spaces of the first box 10 and the second box 20 can be further divided. In addition, the rigidity of the first box 10 and the second box 20 is improved. Furthermore, the closer the second side wall section 112 of the first box 10 and the support section 61 of the second box 20 are brought together, the more the rigidity of not only the first box 10 and the second box 20 but also the rigidity of the entire storage box 1 can be improved. In the storage box 1, when viewed in the front-to-back direction, the second side wall section 112 of the first box 10 and the support section 61 of the second box 20 are located at an overlapping position. Therefore, while improving the overall rigidity of the storage box 1, when heavy items are stored, the storage box 1 becomes less likely to deform, and the strength of the storage box 1 can be improved.

[0081] <Variation> A modified example of the storage box 1 will be described using Figure 8. Figure 8 is a schematic cross-sectional view showing various modified examples of the storage box 1 in the embodiment of the present invention. Figures 8(A) to 8(D) correspond to Figure 4, respectively. In the following, components similar to those in the above embodiment will be denoted by the same reference numerals and their descriptions will be omitted, while only components different from the above embodiment will be described.

[0082] In the above-described embodiment, each wall constituting the side surface of the first box body 10 of the storage box 1 is formed by folding a sheet material in one direction in the thickness direction at one end in the width direction, which is one direction of the common wall member 30. Each wall constituting the side surface of the second box body 20 is formed by folding a sheet material in the other direction in the thickness direction at the other end in the width direction, which is the other direction of the common wall member 30. However, as shown in Figure 8(A), each wall constituting the side surface of the first box body 10 and the second box body 20 may be formed by a folding method other than that described above.

[0083] In the blank of the storage box 1 shown in Figure 8(A), a common part for forming a common wall member 30, a first box-specific part for forming a part of the first box body 10, and a second box-specific part for forming a part of the second box body 20 are connected side by side. In the assembly of the storage box 1 shown in Figure 8(A), for example, a part of one surface of the fourth side wall 114 of the first box body 10 and a part of the other surface of the common wall member 30 are bonded together in contact. Also, a part of one surface of the first side wall 211 of the second box body 20 and a part of the other surface of the common wall member 30 are bonded together in contact.

[0084] Furthermore, as shown in Figure 8(A), the first box 10 and the second box 20 do not necessarily have support parts.

[0085] In the embodiment described above, the width of the common wall member 30 is the same as the width of the storage box 1. However, as shown in Figure 8(B), the width of the common wall member 30 may be smaller than the width of the storage box 1.

[0086] In the embodiment described above, the first box body 10 and the second box body 20 of the storage box 1 overlap in a manner that is partially offset in the width direction when viewed in the depth direction. However, as shown in Figure 8(C), the first box body 10 and the second box body 20 may not overlap when viewed in the depth direction and may be separated from each other in the width direction.

[0087] In the embodiment described above, the first box body 10 and the second box body 20 of the storage box 1 are rectangular cylindrical shapes when viewed in the height direction. However, as shown in Figure 8(D), the first box body 10 and the second box body 20 may each be semi-cylindrical when viewed in the height direction. Alternatively, the first box body 10 and the second box body 20 may each have a polygonal cylindrical shape extending in the height direction.

[0088] According to the above configuration, the storage box 1 is more stable when placed on any of the sides of the polygonal cylindrical shape.

[0089] [Other embodiments] In the embodiment described above, the storage box 1 is a paper box formed by folding a single sheet of material. However, the storage box may be formed by folding a sheet of material other than paper. For example, the storage box may be made of a resin sheet or corrugated cardboard.

[0090] In the embodiment described above, the dimensions of the first box 10 and the second box 20 in the depth, width, and height directions are substantially the same. However, the dimensions of the first box 10 and the second box 20 in each direction may be different.

[0091] In the embodiment described above, the first box body 10 and the second box body 20 of the storage box 1 overlap in a manner that is partially offset in the width direction when viewed in the depth direction. However, the first box body and the second box body of the storage box may overlap in a manner that is partially offset in the height direction when viewed in the depth direction.

[0092] In the above-described embodiment, the lids 12 and 22 are located at the upper end in the height direction of the storage box 1, and the bottoms 13 and 23 are located at the lower end in the height direction of the storage box 1. However, the lids may be located at the lower end in the height direction of the storage box, and the bottoms may be located at the upper end in the height direction of the storage box. Also, in the first and second boxes, the lids and bottoms are connected to the upper end of the fourth side wall. The lids and bottoms may be connected to any position on the side wall. The lids and bottoms may be separate from the storage box 1.

[0093] In the above-described embodiment, in the storage box 1, the first box body 10 and the second box body 20 overlap with a partial misalignment when viewed in the depth direction, which is perpendicular to the common wall member 30. However, in the storage box 1, the first box body and the second box body may overlap while aligned in the width direction when viewed in the direction perpendicular to the common wall member.

[0094] In the above-described embodiment, the support portion 51 of the first box 10 is located to the right of the center of the first box 10 in the width direction. The support portion 61 of the second box 20 is located to the right of the center of the second box 20 in the width direction. The support portion of the first box or the second box may be located in the center of the first box or the second box in the width direction, or it may be located further than the center in the width direction.

[0095] Furthermore, the width of the second space in the first box may be smaller than the width of the second space in the second box. A specific explanation using Figure 9 is as follows. Figure 9 is a schematic cross-sectional view showing a storage box 1A in another embodiment of the present invention.

[0096] As shown in Figure 9, in storage box 1A, the width of the second space SP12 of the first box body 10 is smaller than the width of the second space SP22 of the second box body 20. Therefore, the second space SP12 of the first box body 10 can accommodate items even smaller than those stored in the second space SP22 of the second box body 20. Furthermore, the first space SP11 and second space SP12 of the first box body 10 and the first space SP21 and second space SP22 of the second box body 20, which are of different sizes, allow for the efficient storage of items of various sizes.

[0097] Furthermore, the closer the support portion 51 of the first box body 10 and the support portion 61 of the second box body 20 are brought together, the more the rigidity of not only the first box body 10 and the second box body 20 but also the overall rigidity of the storage box 1A can be improved.

[0098] Furthermore, when viewed in the front-to-back direction, the support portion 51 of the first box body 10 and the support portion 61 of the second box body 20 may be located in an overlapping position. The width of the second space SP12 of the first box body 10 may be greater than the width of the second space SP22 of the second box body 20.

[0099] In the embodiment described above, the width of the second space SP22 of the second box 20 is greater than the width of the second space SP12 of the first box 10. However, the width of the second space of the first box and the width of the second space of the second box may be the same. Also, the width of the second space of the first box 10 may be greater than the width of the second space of the second box.

[0100] In the embodiment described above, the storage box 1 is assembled by gluing the blank BL1 in place. However, in the assembly of the storage box, fasteners or the like may be used to fix the predetermined position in place, in addition to gluing.

[0101] Although embodiments of the present invention have been described above, the embodiments described above are merely examples for carrying out the present invention. Therefore, the invention is not limited to the embodiments described above, and it is possible to carry out the invention by appropriately modifying the embodiments described above without departing from the spirit of the invention.
