Description

[Technical field]

[0001] The present invention relates to a storage case that allows various items to be easily taken out and stored. [Background technology]

[0002] As a conventional storage case, Patent Document 1 discloses a packaging box in which two side plates forming a peripheral wall are connected together, and an inner end plate and an outer end plate extending upward from each side plate are folded inward so as to overlap each other substantially horizontally to close the ends. This packaging box is configured such that the side plates are curved outward, and a shaking opening formed in the inner end plate is covered by the outer end plate, and by gripping both ridges of the peripheral wall, the curvature of the side plates changes elastically to open the shaking opening, allowing the contents to be shaken out.

[0003] [Patent Document 1] JP 2006-232336 A Summary of the Invention [Problem to be solved by the invention]

[0004] The above-mentioned conventional packaging boxes are configured to open and close the casting outlet by relative movement of the inner end plate and outer end plate due to deformation of the peripheral wall, but there was a problem in that it was difficult to sufficiently ensure the amount of movement of the inner end plate and outer end plate and the size of the casting outlet, making it difficult to remove the contents.

[0005] In addition, conventional storage cases generally referred to as "pillow cases" or "pillow-shaped cases" are constructed so that the upper inner and outer end plates overlap each other to close the opening, but even if the ridges on both sides of the peripheral wall are grasped to elastically change the shape of the curved side plates, the inner and outer end plates do not open. Therefore, when removing the contents, it is necessary to grasp the case with one hand and open the inner and outer end plates in sequence with the other hand, which creates the problem that it is not possible to open the opening with one hand to remove the contents.

[0006] Furthermore, when placing items in the storage case for safekeeping, it is necessary to use both hands to close the opening in the reverse order to that for removing the contents described above, which makes the process complicated.

[0007] SUMMARY OF THE PRESENT DISCLOSURE An object of the present invention is to provide a storage case whose opening can be opened and closed easily and reliably. [Means for solving the problem]

[0008] The object of the present invention is to provide a storage case having a flat tube shape formed by joining both side edge portions of a pair of rectangular sheet members to each other, with an opening at at least one end, and the opening opening being opened by elastic deformation of the pair of sheet members when the both side edge portions are pressed in a direction approaching each other, the storage case further comprising a cover piece connected to the end edge of the sheet members that forms the opening, The lid pieces are provided on both of the pair of sheet members and each has a plurality of folding pieces that can be folded along a folding line. The lid pieces are folded a plurality of times toward the inside of the sheet member along each folding line so as to roll up the folding pieces on the tip side, and the folding pieces on the base end side come into contact with each other to cover the opening. When the side edges are pressed in a direction approaching each other to open the opening, each of the lid pieces deforms to fit the inner surface of the sheet member. This is achieved by the containment case. Effect of the Invention

[0011] According to the present invention, it is possible to provide a storage case whose opening can be opened and closed easily and reliably. [Brief description of the drawings]

[Figure 15] FIG. 15 is a plan view of the container case shown in FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. Fig. 1 is a development view of a storage case according to one embodiment of the present invention, and Fig. 2 is a front view showing the storage case shown in Fig. 1 in an assembled state.

[0014] The storage case 1 shown in Fig. 1 and Fig. 2 can be manufactured by punching out a blank sheet made of synthetic resin, and then performing a folding process and a bonding process on the punched out sheet of material. The storage case 1 is preferably made of a material having elastic flexibility and may be made of, for example, paper or thin metal plate, in addition to synthetic resin. The plate thickness of the storage case 1 is not particularly limited, and may be, for example, about 50 µm to 3 mm. By forming the storage case 1 from a transparent material, it becomes easy to check the contents, and products can be stored and removed while checking the amount. However, the storage case 1 may be formed from an opaque or colored material.

[0015] As shown in FIG. 1, the storage case 1 of this embodiment is made of a single material sheet, and has a shape in which the side edges of a pair of rectangular sheet members 2a, 2b are connected to each other by a connecting portion 4 extending vertically. A glue strip 3 extending approximately parallel to the connecting portion 4 is continuously provided on the side edge of one sheet member 2a opposite to the connecting portion 4. The glue strip 3 has an appropriate width (for example, 1 mm or more) that can be adhered or welded to the other sheet member 2b, and may be larger than the width of the storage case 1. The pair of sheet members 2a, 2b are folded at the connecting portion 4 so as to face each other, and the glue strip 3 is adhered or welded to the outer surface of the other sheet member 2b, so that the storage case 1 having openings 12 at both the top and bottom ends is formed into a flat tube shape as shown in FIG. 2.

[0016] A lid piece 10 is connected to the upper and lower edges of a pair of sheet members 2a, 2b that form an opening 12 via a fold line 11. The fold line 11 can be formed, for example, by a general fold line, a half cut, a perforation, or the like, and as shown by the dashed line in Fig. 2, the lid piece 10 can be folded nearly 180 degrees toward the inner surface of each sheet member 2a, 2b.

[0017] Fig. 3 is a side view of a main part showing the vicinity of the upper opening 12 of the storage case 1 shown in Fig. 2. Fig. 4 is a plan view of the opening 12 of the storage case 1 viewed from above. As shown in Figs. 3 and 4, the lid pieces 10 folded inwardly of the pair of sheet members 2a, 2b come into contact with each other to cover the opening 12.

[0018] In the storage case 1 having the above-mentioned configuration, the lid pieces 10 connected to the edges of each sheet member 2a, 2b forming the opening 12 can be folded inward of the sheet members 2a, 2b, respectively, to increase the rigidity of the sheet members 2a, 2b in the vicinity of the opening 12, thereby enabling the opening 12 to be reliably covered by the lid pieces 10.

[0019] When opening the opening 12, the pair of sheet members 2a, 2b are pressed against both side edges 6 in a direction approaching each other (in the direction of the arrow in FIG. 4), so that the sheet members 2a, 2b are elastically deformed and curved outwardly convex, as shown in FIG. 5. With such deformation of the sheet members 2a, 2b, the lid pieces 10 are subjected to a force directed toward the inner surface of the sheet members 2a, 2b (in the direction of the arrow in FIG. 5) and deform to conform to the inner surface of the sheet members 2a, 2b, so that the opening 12 can be opened reliably with a sufficient size. On the other hand, when the pressure on the both side edges 6 is released, the pair of elastically deformed sheet members 2a, 2b return to their original shape shown in FIG. 4, and the opening 12 is closed by the elastic force (repulsion force) of the lid pieces 10. By making the width of the storage case 1 large enough to press the both side edges 6 with one hand, the opening 12 can be opened and closed easily and reliably with one hand.

[0020] As shown in Fig. 1, the storage case 1 of this embodiment has cutouts 5 formed above and below a connecting portion 4 that connects a pair of sheet members 2a, 2b, and is formed so that the vertical length of the adhesive strip 3 is shorter than the vertical length of the sheet members 2a, 2b. As a result, as shown in Fig. 3, notches 7 are formed near the opening 12 in both side edges 6, making it easier to open the opening 12. However, the notches 7 are not essential to the present invention, and the configuration may not include the notches 7.

[0021] The lid piece 10 of this embodiment is tapered so that the length L1 (see FIG. 2) is the longest at the center in the width direction of the sheet members 2a and 2b, and when the opening 12 is opened, the lid piece 10 can easily follow the deformation of the sheet member 2 to reliably open the opening. However, the shape of the lid piece 10 is not particularly limited, and for example, the lid piece 10 may be formed in a rectangular shape so that the length L1 is constant in the width direction of the sheet members 2a and 2b. The length L1 of the lid piece 10 shown in FIG. 2 is preferably 3 to 70 mm, more preferably 10 to 20 mm, from the viewpoint of easily and reliably opening and closing the opening 12 while suppressing the manufacturing cost of the storage case 1. It is preferable that the lid piece 10 is folded inward of the sheet members 2a and 2b as in this embodiment, but the lid piece 10 may be folded outward of the sheet members 2a and 2b (similar to each of the following embodiments).

[0022] Fig. 6 is a development view of a storage case according to another embodiment of the present invention, and Fig. 7 is a rear view showing the assembled state of the storage case shown in Fig. 6. In the following drawings, components having substantially the same functions as those of the storage case 1 shown in Figs. 1 and 2 are designated by the same reference numerals, and duplicated explanations will be omitted.

[0023] The storage case 1 shown in FIG. 6 is formed from a single sheet of material, and has a shape in which a bottom 13 is interposed between a pair of sheet members 2a and 2b. The pair of sheet members 2a and 2b are connected to each other by a connecting portion 4 extending in the width direction through the center of the bottom 13. The adhesive strips 3 are provided on both side edges of one of the sheet members 2a. The storage case 1 shown in FIG. 6 is formed by folding the pair of sheet members 2a and 2b so as to face each other at the connecting portion 4 provided approximately in the center in the vertical direction of the material sheet, and gluing or welding each adhesive strip 3 to both sides of the other sheet member 2b, as shown in FIG. 7, so that the storage case 1 has a bottom 13 at the lower end side and an opening 12 at the upper end side, and is formed into a flat cylindrical shape. By making the bottom 13 into a gusseted shape as in this embodiment, a wide variety of items can be stored. Each lid piece 10 is folded toward the inside of the sheet members 2a, 2b, but the lid piece 10 may be folded at the same time as each adhesive piece 3 is adhered or welded, or the lid piece 10 may be folded after each adhesive piece 3 is adhered or welded.

[0024] As shown in Fig. 6, the cover piece 10 has a plurality of folding pieces 10a, 10b, which are provided on the edge of each of the sheet members 2a, 2b opposite the connecting portion 4. Each folding piece 10a, 10b can be folded at a folding line 11a, 11b, respectively. The folding lines 11a, 11b can be formed, for example, by not only a general folding line but also a half cut, a perforation, or the like.

[0025] FIG. 8 is a cross-sectional view of a main part of the storage case 1 shown in FIG. 7, showing the vicinity of the opening 12. Each of the lid pieces 10 is folded toward the inside of the sheet members 2a and 2b at the fold line 11a, and is folded so as to roll up the folded piece 10b on the tip side at the fold line 11b. The folded pieces 10a on the base end side of each of the lid pieces 10 abut against each other to cover the opening 12. In this way, by configuring the lid piece 10 to be folded multiple times toward the inside of the sheet members 2a and 2b, both the opening force and closing force of the lid piece 10 for the opening 12 can be increased, so that the opening 12 can be opened and closed more easily and reliably by pressing and releasing the pressure on both side edges 6 shown in FIG. 7. The number of times that the lid piece 10 is folded is not particularly limited, and it may be folded three or more times.

[0026] FIG. 9 is a development view of a storage case according to yet another embodiment of the present invention, and FIG. 10 is a front view showing the state in which the storage case shown in FIG. 9 is assembled. The storage case 1 shown in FIG. 9 is formed from two material sheets, and each material sheet has a lid piece 10 connected to the edge of a pair of sheet members 2a, 2b. The lid piece 10 has a plurality of folding pieces 10a, 10b, and each folding piece 10a, 10b can be folded at folding lines 11a, 11b, respectively. The storage case 1 shown in FIG. 9 is formed by folding each lid piece 10 toward the inside of the sheet members 2a, 2b to overlap the pair of sheet members 2a, 2b, and then bonding or welding the peripheral parts excluding the lid piece 10 to form a joint part 14, as shown in FIG. 10, so that the storage case 1 is formed into a flat tube shape with a closed lower end and an opening 12 on the upper end side. In the storage case 1 of this embodiment, the opening 12 can be easily and reliably opened and closed by the lid piece 10 by pressing and releasing the pressure on both side edges 6. The pair of sheet members 2a, 2b may be bonded or welded to each other by using an adhesive piece provided on one of the sheet members 2a, 2b, instead of bonding or welding the peripheral edges.

[0027] FIG. 11 is a development view of a storage case according to yet another embodiment of the present invention, and FIG. 12 is a front view showing the state in which the storage case shown in FIG. 11 is assembled. The storage case 1 shown in FIG. 11 is formed from one material sheet, and has a shape in which the side edges of a pair of sheet members 2a and 2b are connected to each other by a connecting portion 4. A glue strip 3 is connected to the side edge of one sheet member 2a opposite to the connecting portion 4. A cover 15 is connected to the upper end edge of one sheet member 2a, and a lid piece 10 having a plurality of folded pieces 10a and 10b is connected to the upper end edge of the other sheet member 2b. A bottom portion 13 is provided at the lower end edges of the pair of sheet members 2a and 2b. A hanging piece 15a is formed at the center of the cover 15 by a cut, and a through hole 15b is formed in the hanging piece 15a. An insertion piece 16 that can be inserted into a slit 17 formed by cutting out the other sheet member 2b is provided at the upper end of the cover 15.

[0028] 11, the cover piece 10 is folded toward the inside of the sheet member 2b, and the pair of sheet members 2a, 2b are folded at the connecting portion 4 so as to face each other, and then the adhesive piece 3 is adhered or welded to the sheet member 2b, and then the bottom 13 is assembled, so that the storage case 1 is formed in a flat cylindrical shape having the bottom 13 at the lower end side and the opening 12 at the upper end side, as shown in FIG. 12(a). In the storage case 1 of this embodiment, the opening 12 can also be easily and reliably opened and closed by the cover piece 10 by pressing and releasing the pressure on both side edges 6.

[0029] When products are stored in the storage case 1 and the product is displayed in a store such as a convenience store, the cover 15 can be folded from the state shown in Fig. 12(a) so as to cover the other sheet member 2b and the insertion piece 16 can be inserted into the slit 17, so that the opening 12 can be covered with the cover 15 as shown in Fig. 12(a). Also, as shown in Fig. 12(b), a hanging rod for displaying products provided in a store can be inserted into the through hole 15b of the hanging piece 15a separated from the cover material 15 by the cut line, so that the product can be displayed by hanging.

[0030] The cover piece 10 of the storage case 1 shown in FIG. 12 is not provided on one of the sheet members 2a, but is provided only on the other sheet member 2b, and the cover piece 10 can be abutted against the inner surface of one of the sheet members 2a to cover the opening 12. With this configuration, the products stored in the storage case 1 can be easily removed from the opening 12 by smoothly sliding along the inner surface of the one of the sheet members 2a that does not have the cover piece 10. The cover piece 10 may be folded so that the folded piece 10b on the tip side is rolled up at multiple fold lines 11a, 11b as shown in FIG. 13(a), or may be folded so that the peaks and valleys are alternately arranged at multiple fold lines 11a, 11b as shown in FIG. 13(b). Even when the cover piece 10 is provided on only one of the sheet members 2a, 2b, the cover piece 10 may be folded only once, or may be folded three or more times.

[0031] Although the embodiment of the present invention has been described above in detail, the specific aspects of the present invention are not limited to the above embodiment. For example, in this embodiment, the lid piece 10 is provided over the entire width of the sheet member 2, but as shown in the front view of the main part in FIG. 14, the lid piece 10 may be provided only on a part of the sheet member 2a, such as the center of the sheet member 2a in the width direction. According to this configuration, as shown in the plan view in FIG. 15, the lid piece 10 can cover necessary parts such as the center of the opening 12, so that a relatively large article can be reliably held in the storage case 1. Note that the pair of sheet members 2a, 2b and the lid piece 10 shown in FIG. 14 and FIG. 15 are formed with through holes through which a hanging rod for displaying goods is inserted.

[0032] The items that can be stored in the storage case of the present invention are not particularly limited, but examples include fishing equipment such as lures, insulin needles, incense sticks, travel sets, stationery, push pins, wood screws, cosmetics, cosmetic accessories, portable ashtrays, etc. [Explanation of symbols]
