DETAILED DESCRIPTION OF THE INVENTION

[0014] <<Regarding a storage case according to one embodiment of the present invention>> Hereinafter, one embodiment of the present invention (hereinafter referred to as the present embodiment) will be described with reference to the accompanying drawings. In the drawings, each component is shown somewhat simplified and schematic to make the explanation easier to understand, and the size (dimensions) of each component and the spacing between components shown in the drawings may differ from the actual ones. In addition, in this specification, "horizontal, vertical, right-angled, parallel" includes the range of error generally accepted in the technical field of the present invention, and also includes states where the deviation is less than a few degrees (e.g., 2 to 3 degrees) from the strict horizontal, vertical, right-angled, and parallel. The storage case will be described below.

[0015] Fig. 1 is a schematic perspective view showing an example of a storage case according to an embodiment of the present invention. Fig. 2 is a schematic perspective view showing an inner box and an outer box of an example of a storage case according to an embodiment of the present invention. Fig. 3 is a schematic perspective view showing a bed using an example of a storage case according to an embodiment of the present invention. The storage case 10 shown in Fig. 1 has an outer box 12 with an opening 12a and an inner box 14 with an opening 14a. The outer box 12 and the inner box 14 have external shapes that are, for example, rectangular parallelepipeds or cubes. The outer box 12 and the inner box 14 have external shapes that are similar. The inner box 14 is stored inside the outer box 12. The inner box 14 stores, for example, clothing and the like. The state in which the inner box 14 is stored inside the outer box 12 is called a drawer 15. The drawer 15 has a double structure of the outer box 12 and the inner box 14. Storage case 10 has a case body 16 in which drawer 15 is stored. Normally, drawer 15 is used while stored in case body 16. Drawer 15 is pulled out horizontally from case body 16. Clothes and the like are stored in the drawer 15, or more precisely, in the inner box 14, and the drawer 15 is pulled out as needed to remove the clothes and the like. A handle 13, for example, is provided on the side surface 12c (front surface) of the outer box 12 to make it easier to pull out the drawer 15.

[0016] When using multiple storage cases 10, multiple outer boxes 12 are prepared by removing the outer boxes 12 from each storage case 10, and then the multiple outer boxes 12 are combined to form a bed 18 as shown in Figure 3. Here, the multiple storage cases 10 are the same size. The bottom walls 12b of the outer boxes 12 removed from each storage case 10 are used as the sleeping area 18a of the bed 18. When configuring the bed 18 using the storage case 10, the drawer 15 is first pulled out from the case body 16. Next, as shown in FIG. 2, in the drawer 15, the inner box 14 is taken out from the outer box 12, and the outer box 12 and the inner box 14 are separated. The separated inner box 14 contains clothes and the like, and is stored in this state in the case body 16 shown in Fig. 1. In other words, the inner box 14 alone is used as a drawer 15. Next, as shown in Fig. 3, the outer boxes 12 are placed with the bottom wall 12b facing upward, and multiple outer boxes 12 are lined up as shown in Fig. 3, and the outer surfaces 12e of adjacent outer boxes 12 are butted together to form a bed 18. In the bed 18, the bottom wall 12b of the outer box 12 becomes the sleeping portion 18a.

[0017] As described above, by using the outer box 12 of the storage case 10 to form the bed 18, the storage case 10 is normally used, eliminating the need for a dedicated storage space for the bed or its components, and the bottom wall 12b of the outer box 12 can be used as the sleeping area 18a. This effect is particularly effective in dwellings such as condominiums and apartments where living space is limited, where it is difficult to secure a dedicated storage space. Furthermore, it can also be flexibly used when a bed is needed, for example, when a guest comes to stay overnight.

[0018] Beds 18 of various sizes (see Figure 3) can be made by changing the number of outer boxes 12. The number of outer boxes 12 constituting bed 18 is not particularly limited, and is determined appropriately depending on the height of the user, the number of storage cases 10, etc. Furthermore, when multiple storage cases 10 are used, it is possible to connect the outer boxes 12 of the multiple storage cases 10. This allows the sleeping area 18a (see FIG. 3) to be made in various sizes, and as a result, beds 18 (see FIG. 3) of various sizes can be made.

[0019] The storage case 10 is made of cardboard, and the outer box 12, inner box 14, and case body 16 are all made of cardboard. Cardboard is a lightweight material, so the bed 18 can be easily formed. The case body 16 is the frame of the storage case 10, and bears the load when the storage cases 10 are stacked. For this reason, it may not be made of cardboard, but may be made of plastic or other materials that are stronger than cardboard. Furthermore, the case body 16 is not limited to a configuration in which one drawer 15 is stored in one case body 16, but may be configured to store multiple drawers 15. For example, it may be configured to store two drawers 15 placed side by side, or two drawers placed side by side in two vertical rows, for a total of four drawers 15.

[0020] For example, as shown in Fig. 4, a plurality of storage cases 10 are stacked and stored in the lower level 22b of a closet 20. The number of storage cases 10 is determined appropriately depending on the purpose and the size of the closet 20. The closet 20 is divided into an upper level 22a and a lower level 22b by a shelf 21a. The upper level 22a is further divided by a partition 21b. As described above, when the outer box 12 is used as a bed 18, only the inner box 14 is stored as the drawer 15 in the case body 16. Therefore, even when the outer box 12 is used as a bed 18, a dedicated storage space is not required. Also, because the storage case 10 is stored in the lower level 22b of the closet 20 as described above, even when the outer box 12 is not used as a bed 18, a dedicated storage space is not required.

[0021] In the storage case 10, it is preferable to provide a reinforcing portion 26 (see FIG. 5) on the outer box 12. By providing the reinforcing portion 26, the durability of the bed 18 (see FIG. 3) is improved, and the load-bearing capacity is also increased. Fig. 5 is a schematic diagram showing the reinforcing portion of an example of a storage case according to an embodiment of the present invention, Fig. 6 is a schematic diagram showing an enlarged view of the reinforcing portion of an example of a storage case according to an embodiment of the present invention, Fig. 7(a) is a schematic diagram showing the engaging portion of the reinforcing portion of a first example of a storage case according to an embodiment of the present invention, and Fig. 7(b) is a schematic diagram showing the engaging portion of the reinforcing portion of a second example of a storage case according to an embodiment of the present invention. Note that Fig. 7(b) shows the state before engagement. As shown in FIGS. 5 and 6, the outer box 12 has, for example, a double structure having an outer wall 23a and an inner wall 23b. As shown in FIG. 6 , the first wall portion 24a and the second wall portion 24b of the inner wall 23b, which are in contact with each other at the corner 12d of the outer box 12, are each provided with a foldable reinforcing piece 25 made of the inner wall 23b. The reinforcing piece 25 is a part of the inner wall 23b. For example, the reinforcing piece 25 is partially cut out from the inner wall 23b and is not joined to the outer wall 23a. The reinforcing piece 25 can be bent toward the corner 12d at the bent end 23d. For example, the bent end 23d is provided on both the first wall portion 24a and the second wall portion 24b at a position equidistant from the corner 12d, and the reinforcing piece 25 has the same length. 7(a), the tip 25a of the reinforcing piece 25 is formed, for example, in a sinusoidal shape. The inner wall 23b is provided with a notch that matches the shape of the tip 25a of the reinforcing piece 25. The reinforcing piece 25 is bent at the bent end 23d toward the corner 12d, and the tip ends 25a of the reinforcing pieces 25 are overlapped and engaged with each other to form the reinforcing portion 26.

[0022] The shape of the tip 25a of the reinforcing piece 25 is not particularly limited to the shape shown in Fig. 7(a) as long as it can be engaged, and may be, for example, the shape shown in Fig. 7(b). The tip 25a of the reinforcing piece 25 shown in Fig. 7(b) has, for example, a triangular notch 28a formed at a position halfway in the height direction Z, and has two trapezoidal protrusions 28b along the height direction Z. When forming the reinforcing portion 26, the notches 28a are aligned in the height direction Z so that the trapezoidal protrusions 28b face each other. Then, the opposing protrusions 28b are engaged with each other by overlapping the upper protrusion 28b right-side up and the lower protrusion 28b left-side up in the height direction Z, for example. This forms the reinforcing portion 26 shown in FIG. 6. The opposing protrusions 28b can be overlapped with each other, for example, by overlapping the upper protrusion 28b with the left side facing up and the lower protrusion 28b with the right side facing up in the height direction Z. In addition, the shape of the protrusions 28b is not limited to a trapezoidal shape.

[0023] 7(a), the reinforcing pieces 25 are provided over the entire area of ​​the outer box 12 in the height direction Z, but this is not limited to this. The length of the reinforcing pieces 25 in the height direction Z is set appropriately depending on the strength of the outer box 12. Furthermore, although multiple reinforcing pieces 25 may be provided along the height direction Z, in consideration of the assembly of the reinforcing portion 26 and the processing of the reinforcing pieces 25, it is preferable to provide one reinforcing piece 25 at each corner 12d of the outer box 12 as shown in FIG. The outer wall 23a, the inner wall 23b, and the reinforcing piece 25 that constitutes the reinforcing portion 26 are made of cardboard.

[0024] In the storage case 10, as described above, a plurality of outer boxes 12 are joined together to form the bed 18 (see FIG. 3). In order to join the outer boxes 12 together, for example, a hook-and-loop fastener 27 (see FIG. 8) can be used. Fig. 8 is a schematic diagram showing the arrangement of hook-and-loop fasteners in an example of a storage case according to an embodiment of the present invention, and Fig. 9 is a schematic diagram showing the connection of an outer box using hook-and-loop fasteners in an example of a storage case according to an embodiment of the present invention. In Fig. 8 and Fig. 9, the same components as those shown in Fig. 5 to Fig. 7(a) and (b) are designated by the same reference numerals, and detailed description thereof will be omitted.

[0025] As shown in Fig. 8, the hook-and-loop fastener 27 has a base portion 27a and a connecting portion 27b. The base portion 27a is disposed between the outer wall 23a and the inner wall 23b in a region 23c, and the connecting portion 27b is disposed inside the outer box 12. The connecting portion 27b is the portion that actually performs the fastening, and can be attached and detached by itself. The configuration of the connecting portion 27b is not particularly limited as long as it is a hook-and-loop fastener, and various known fasteners can be used. The connecting portion 27b is configured to be bent at the edge 12f of the opening 12a of the outer box 12. The hook-and-loop fastener 27 can be disposed on the outer surface 12e of the outer box 12 by folding the connecting portion 27b at the edge 12f of the opening 12a of the outer box 12. When the hook-and-loop fastener 27 is used to join the outer boxes 12 together, the joining portion 27b is folded back at the edge 12f of the outer box 12 and disposed on the outer surface 12e of the outer box 12. The outer surface 12e is the surface that faces the outer boxes 12 when they are joined together. When the hook-and-loop fastener 27 is not used to connect the outer boxes 12 together, the connecting portion 27b of the hook-and-loop fastener 27 is folded back toward the inner wall 23b of the outer box 12 and arranged on the inner wall 23b side of the outer box 12. The inner box 14 is stored in the outer box 12 with the connecting portion 27b arranged on the inner wall 23b side of the outer box 12. Therefore, in the drawer 15 (see FIG. 1 ), the hook-and-loop fastener 27 is present between the outer box 12 and the inner box 14 and is not visible, but when the inner box 14 is removed from the outer box 12, the hook-and-loop fastener 27 appears. When joining the outer boxes 12, after removing the inner box 14, the joining portions 27b are folded back at the edges 12f of the outer boxes 12 as shown in Figure 9, and the joining portions 27b are brought together to join the outer boxes 12. As a result, a plurality of outer boxes 12 can be joined together to easily make a bed 18 (see Figure 3).

[0026] Fig. 10 is a schematic diagram showing the arrangement of magnets in an example of a storage case according to an embodiment of the present invention. In Fig. 8 and Fig. 9, the same components as those shown in Fig. 5 to Fig. 7(a) and (b) are designated by the same reference numerals, and detailed description thereof will be omitted. In the storage case 10, as described above, the multiple outer boxes 12 are joined together with hook-and-loop fasteners 27 (see FIG. 8) to form the bed 18 (see FIG. 3), but other than this, for example, magnets 30 can also be used.

[0027] 10, the magnet 30 is disposed between the outer wall 23a and the inner wall 23b in a space 23c. In this case, the magnet 30 is not visible even when the inner box 14 is removed from the outer box 12. Alternatively, the magnet 30 may be placed on the surface of the inner wall 23b. In this case, the magnet 30 is visible when the inner box 14 is removed from the outer box 12. Furthermore, since there is a possibility that the magnet 30 may come into contact with the inner box 14 and fall off, it is preferable to place the magnet 30 between the outer wall 23a and the inner wall 23b, as shown in FIG. There are no particular limitations on the magnet 30 as long as it can connect the outer boxes 12 together, but it is preferable that it is small and have strong magnetic force. For this reason, a neodymium magnet is preferable as the magnet 30. Furthermore, the shape of the magnet 30 is preferably a sheet or plate. The number of magnets 30 is not particularly limited as long as it can join the outer boxes 12 together, but a plurality of magnets is preferable. The number of magnets 30 is more preferably two or more per side of one box.

[0028] In the case of magnets 30, when joining the outer boxes 12, after removing the inner boxes 14, the outer surfaces 12e of the outer boxes 12 on which the magnets 30 are provided are brought close together so that they face each other, as shown in Fig. 10, and the outer boxes 12 are joined together by magnetic force. When magnets 30 are used, the outer boxes 12 can be joined together simply by bringing them close together. As a result, the bed 18 (see Fig. 3) can be easily made. In order to connect the outer boxes 12 to each other, the opposing magnets 30 on the opposing outer boxes 12 have different polarities. For example, when magnets 30 are provided on opposing outer surfaces 12e, one outer surface 12e is arranged with its north pole facing outward, and the other outer surface 12e is arranged with its south pole facing outward. In this way, by aligning the orientations of the multiple outer boxes 12, the opposing magnets 30 have different polarities.

[0029] Fig. 11 is a schematic perspective view showing another example of the storage case according to the embodiment of the present invention. Figs. 12(a) and 12(b) are schematic perspective views for explaining another usage form of the storage case according to the embodiment of the present invention. As shown in Fig. 11, the storage case 10 may be provided with a partition plate 32 in the drawer 15. The partition plate 32 divides the inner box 14 into a first area 14c and a second area 14b. For example, summer clothes are stored in the first area 14c, and winter clothes are stored in the second area 14b. By changing the orientation of the drawer 15 (for example, by swapping the front and back of the drawer 15), it is possible to change clothes. The number of partition plates 32 is not limited to one, but may be multiple, and the number of partition plates 32 is determined appropriately depending on the application.

[0030] In addition, the inner box 14 is stored in the outer box 12 with the opening 12a of the outer box 12 and the opening 14a of the inner box 14 aligned, but this is not limited thereto. For example, as shown in FIG. 12(a), the opening 12a of the outer box 12 and the opening 14a of the inner box 14 may be opposed to each other, and the inner box 14 may be stored in the outer box 12 as shown in FIG. 12(b). This results in the inner box 14 being covered by the outer box 12 (i.e., closed). In this state, the drawer 15 is formed. When the drawer 15 shown in FIG. 12(b) is stored in the case body 16 shown in FIG. 1, the contents stored in the drawer are not immediately visible when the drawer is pulled out. This makes the drawer suitable for storing items that are not regularly used, valuables, and the like. Furthermore, since the contents stored in the drawer are not immediately visible when the drawer is pulled out, this is also effective for preventing theft. 12(a) can also be provided with the partition plate 32 shown in Fig. 11. That is, the partition plate 32 can be provided in each of the inner box 14 having the reinforcing portion 26 shown in Fig. 5 described above, the inner box 14 having the hook-and-loop fastener 27 shown in Fig. 8, and the outer box 12 having the magnet 30 shown in Fig. 10.

[0031] While the embodiments of the storage case of the present invention have been described above, the above embodiments are merely examples for facilitating understanding of the present invention and are not intended to limit the present invention. In other words, the present invention may be modified or improved without departing from the spirit and scope of the present invention. Furthermore, the present invention naturally includes equivalents thereof. [Explanation of symbols]
