Description

[Technical field]

[0001] The present invention relates to a bottom reinforcement for a storage box, which is detachable and replaceable to cover the bottom of a storage box that is foldable because the bottom is formed, for example, from a sheet-like member, and which can be damaged by repeated use, and which can be folded together with the storage box when not in use, thereby enabling the storage box to be used for a long period of time. [Background technology]

[0002] Conventionally, various storage boxes and containers that can be unfolded and assembled when in use and can be folded and put together compactly when not in use have been proposed and used. In particular, in storage boxes and the like that are used repeatedly, the bottom is often damaged depending on the weight of the stored items, the way they are held, the environment in which they are used, and other factors. In addition, if the bottom is formed of a sheet-like material that can be folded inward, for example, so that the storage box itself can be folded when not in use, the damage becomes significant after repeated use, and the surrounding walls may have to be discarded even if they are still fully usable. On the other hand, even if it is possible to repair the damaged bottom instead of discarding it in order to make effective use of resources, not only is it inconvenient because the box cannot be used while it is repaired, but repairing the corners in particular is troublesome.

[0003] For this reason, for example, protective members that cover the bottom of a storage box in a removable manner have been proposed to protect and reinforce the bottom. For example, Patent Document 1 shows a granular food container, and Patent Document 2 shows a money box with a removable reinforcing frame. The container in Patent Document 1 has a bottom reinforcing member that is open at the top and is detachable from the bottom of a cardboard box body, while the money box in Patent Document 2 has a reinforcing frame with a storage section that fits and stores containers for pachinko balls and medals, and the containers can be freely attached and detached to this reinforcing frame.

[0004] [Patent Document 1] Utility Model Registration No. 3037713 [Patent Document 2] Utility Model Registration No. 3046801 Summary of the Invention [Problem to be solved by the invention]

[0005] The bottom reinforcing members and the like that are supposed to protect the bottoms of the above-mentioned containers and the like have a shape and structure that covers the bottoms of the containers, so even if the containers can be folded and stored compactly when not in use, the bottom reinforcing members and the like retain the shape they have when in use when not in use, making them bulky to store and troublesome and inconvenient to handle. Furthermore, even if the containers are used repeatedly, the bottom reinforcing members and the like must be attached to the bottoms of the containers when they are used, which is time-consuming and troublesome.

[0006] The present invention was created in consideration of the various circumstances that existed in the past as described above, and its object is to provide a bottom reinforcement for a storage box which, when the bottom wall is folded and folded, for example, into a storage box, follows the folding, unfolding and assembly to become essentially integrated with the storage box, making it easy to handle, and which can be easily replaced if damaged after long-term use, allowing the storage box itself to be used for a long period of time. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, the present invention provides a bottom reinforcement device 1 for a storage box that can be attached freely, replaceably and detachably to the bottom wall B1 of a foldable storage box B having a foldable bottom wall B1, and a fastening means 10 is provided on a reinforcement device main body 2 formed in a shape and size that covers the entire area of ​​the bottom wall B1, which covers the bottom wall B1 and attaches to the bottom wall B1 of the storage box B, and this fastening means 10 is characterized in that it comprises a joint portion 11 that is detachably joined to the outer surface of the bottom wall B1, and mounting portions 15, 25, 35 that are detachably attached to the lower part of the surrounding side wall B2 of the storage box B. The joint 11 is formed by a strip-shaped male and female hook-and-loop fastener (11) of a specified width with which the reinforcement body 2 is tightly joined to the outer surface of the bottom wall B1 of the storage box B, and this hook-and-loop fastener (11) can be configured so that when one of the opposing side walls B2 of the storage box B is folded in half and the other is placed as is on top of the folded side wall B2, this hook-and-loop fastener (11) is positioned along the center line of the bottom wall B1, which is along the center line of the other side wall B2 to be placed over it. The first mounting portion 15 can be formed as a mounting piece that is bendably connected to the left and right or front and rear edges of the reinforcement body 2, and this mounting piece (15) can be joined to the lower surface of the side wall B2 by an attachment means such as male and female hook-and-loop fasteners 16. The second mounting portion 25 is formed as a mounting piece that is bendably connected to each of the four surrounding edges of the left and right and the front and back of the reinforcement body 2, and this mounting piece (25) can be configured to surround and join the periphery of the lower part of the side wall B2 to the lower surface of the side wall B2 using an attachment means such as male and female hook-and-loop fasteners 26. The third mounting portion 35 is formed as a band-shaped mounting belt connected to the left and right or front and rear edges of the reinforcement body 2, and this mounting belt (35) can be configured by inserting it into a support loop 38 of a support portion 37 provided on the side wall B2 surface of the storage box B, folding it back, and fixing the folded-back connected mounting belt (35) itself by an attachment means such as a hook-and-loop fastener 36 provided on the mounting belt (35).

[0008] In the bottom reinforcement for a storage box according to the present invention configured as described above, in a foldable storage box B having a foldable bottom wall B1, the bottom reinforcement for a storage box 1 which is attached to cover this bottom wall B1 can be replaced with a new one and attached when it becomes damaged through repeated use, thereby enabling the storage box B to be used for a long period of time without being discarded. The joint 11 of the fastening means 10 provided on the reinforcement body 2 firmly joins the reinforcement body 2 to the bottom wall B1 by means of the outer surface of the bottom wall B1 and a hook-and-loop fastener (11). This hook-and-loop fastener (11) is positioned along the center line of the bottom wall B1 which is along the center line of one of the side walls B2 which is superimposed on the other side wall B2 which has been folded in half, allowing the reinforcement body 2 which is superimposed on the bottom wall B1 to smoothly follow the folding and unfolding operations of the bottom wall B1. The first, second and third mounting portions 15, 25 and 35 attach the outer edge portions of the reinforcing device main body 2 to the lower portion of the side wall B2 of the storage box B, thereby tightly adhering the reinforcing device main body 2 to the bottom wall B1 and not causing any interference with the use of the storage box B. Effect of the Invention

[0009] Since the present invention is configured as described above, for example, in the case of storage box B, which is folded by folding in the bottom wall B1, when the bottom wall B1 is damaged during use, the bottom wall B1 can be reinforced and protected by covering it, and can be used when the storage box B is folded when not in use, following the folding and unfolding and assembly when in use. Therefore, by being substantially integrated with the storage box B, it becomes easy to handle, can be easily replaced if damaged during long-term use, and enables the storage box B itself to be used for a long period of time.

[0010] That is, in the present invention, the reinforcing member main body 2, which is formed in a shape and size to cover the entire foldable bottom wall B1, is provided with fastening means 10 for covering the bottom wall B1 and attaching to the bottom of the storage box B, joint portion 11 which is detachably joined to the outer surface of the bottom wall B1, and mounting portions 15, 25, 35 which are detachably attached to the lower portion of the surrounding side wall B2 of the storage box B. This allows the storage box B to be used for a long period of time, reducing waste disposal, which helps conserve resources and allows the storage box B to be used without waste.

[0011] In addition, the joint 11 in the fastening means 10 is joined to a hook-and-loop fastener (11) previously provided on the bottom wall B1, and this hook-and-loop fastener (11) is arranged in a strip shape on one of the opposing side walls B2 that is folded in and superimposed on the other side wall B2, so that it follows the folding and unfolding assembly operations of the bottom wall B1 and does not impede the use of the storage box B in any way.

[0012] The mounting portions 15, 25, 35 of the fastening means 10 are removably attached to the lower part of the surrounding side wall B2 of the storage box B, thereby supporting the reinforcing device main body 2 covering the bottom wall B1 by pulling it up from the edge of the storage box B toward above the side wall B2, thereby preventing the reinforcing device main body 2 from loosening and maintaining a tightly attached state against the bottom wall B1.

[0013] The reference numerals in the sections of the Means for Solving the Problems and Effects of the Invention are given for ease of reference to the components shown in the drawings. The present invention is not limited to the structures, shapes, etc. shown by the descriptions and reference numerals in the drawings. [Brief description of the drawings]

[0014] [Figure 1] 1 is a partially cutaway exploded perspective view showing one embodiment of the present invention during use. [Diagram 2] FIG. [Diagram 3] FIG. [Figure 4] 13A and 13B show the state when the storage box is folded in accordance with the folding of the storage box, with FIG. 13A being a longitudinal cross-sectional view of the essential parts of the bottom wall portion of the storage box, and FIG. 13B being a transverse cross-sectional view of the side wall portion with some parts omitted. [Diagram 5] FIG. [Figure 6] FIG. 2 is a partially cutaway perspective view of the same in use. [Figure 7] FIG. [Figure 8]FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] One embodiment of the present invention will now be described with reference to the drawings. The reference numeral 1 shown in the drawings denotes a bottom reinforcement for a storage box according to the present invention, which is attached to the outer bottom surface of a specified storage box B. This reinforcement 1 comprises a reinforcement body 2 made of a synthetic resin sheet material of a specified thickness that can be folded or foldable, for example, and a fastening means 10 that allows the reinforcement body 2 to be freely attached and detached to the bottom wall B1 of the specified storage box B.

[0016] Thus, for example, when assembled and unfolded, the storage box B is a box-shaped container that is open upward, and is provided with front, rear, left and right side walls B2 that can be folded around each side of a foldable bottom wall B1, and a bottom wall reinforcing plate that can be folded over the surface of the unfolded bottom wall B1 is connected to any side of the bottom wall B1 so as to be freely raised and lowered. The storage box B is not limited to this example, and it is sufficient that the storage box B to which the reinforcing tool 1 according to the present invention is applied is foldable, and that the bottom wall B1 is folded, preferably inward, when folded.

[0017] The reinforcing device main body 2 itself is formed in a shape and size that covers the entire bottom wall B1 of the storage box B, so that when the storage box B is in use, no part of the bottom wall B1 directly contacts the use surface, but the reinforcing device main body 2 is interposed between the use surface.

[0018] The reinforcing member main body 2 is provided with fastening means 10 which covers the bottom wall B1 and is attached to the bottom of the storage box B. This fastening means 10 comprises a joint portion 11 which is detachably joined to the outer surface of the bottom wall B1, and mounting portions 15, 25, 35 which are detachably attached to the lower portion of the peripheral side wall B2 of the storage box B.

[0019] The joint 11 is tightly joined to the outer surface of the bottom wall B1 of the storage box B, and is folded and unfolded in accordance with the folding or unfolding of the bottom wall B1 so that the reinforcing device main body 2 is integrated with the bottom wall B1 when joined, and is joined to the outer surface of the bottom wall B1 by, for example, male and female hook-and-loop fasteners (11) (see Figure 1).

[0020] This hook-and-loop fastener (11) is formed and arranged in a band-like shape of a specified width on the bottom wall B1 of the storage box B, and when, for example, one of the opposing side walls B2 of the storage box B, such as the left and right side walls, is folded in half and the other, such as the front and rear side walls, is placed directly on top of the folded side wall B2, the hook-and-loop fastener (11) is arranged along the center line of the other side wall B2 that is to be placed on top of the center line of the bottom wall B1 itself (see Figures 1 and 4(A)).

[0021] This improves the conformability when the bottom wall B1 is folded in, and is very useful for compact folding when not in use of the storage box B. Naturally, the hook-and-loop fastener joint 11 is not limited to being arranged in a straight strip shape, but may be in a cross shape, a circle, a circular frame shape, or other shape, as long as it provides good close conformability when joined to the bottom wall B1.

[0022] Furthermore, while the joint 11 joins the reinforcing device main body 2 itself to the bottom wall B1, the mounting portions 15, 25, and 35 are attached to the lower part of the side wall B2 that continues from the edge of the bottom wall B1, thereby making the joining of the reinforcing device main body 2 to the outer surface of the bottom wall B1 even more reliable.

[0023] 1 to 4 is formed as a foldable attachment piece connected to the left and right or front and rear side of the reinforcing device main body 2, and this attachment piece (15) is joined to the lower surface of the side wall B2 with male and female hook-and-loop fasteners 16. The attachment piece (15) itself is in the shape of a strip with a width almost the same as the width of the side of the reinforcing device main body 2. By joining it to the lower part of the left and right or front and rear side walls B2 of the storage box B with the hook-and-loop fasteners 16, it covers the bottom surface of the storage box B together with the reinforcing device main body 2 along the left and right or front and rear direction of the storage box B.

[0024] The second mounting portion 25 shown in Fig. 5 and Fig. 6 is formed as a mounting piece connected to each of the four surrounding sides of the reinforcing device main body 2, which are the left and right, front and rear, so that the mounting piece (25) is joined to the lower surface of the side wall B2 by male and female hook-and-loop fasteners 26. The mounting piece (25) itself is in the shape of a strip with a width almost equal to the width of each of the left and right, front and rear sides of the reinforcing device main body 2. The mounting piece (25) is joined to the lower parts of the left and right, front and rear side walls B2 of the storage box B by the hook-and-loop fasteners 26, so that the lower parts of the side walls B2 are surrounded, and the entire left and right, front and rear areas of the storage box B are covered with the reinforcing device main body 2 and the bottom surface of the storage box B. This ensures that the peripheral parts of the bottom wall B1 are covered, so that the bottom wall B1 can be further protected.

[0025] The third mounting portion 35 shown in Fig. 7 and Fig. 8 is formed as a belt-shaped mounting belt connected to the left and right or front and rear sides of the reinforcing device main body 2, and this mounting belt (35) is inserted into the support loop 38 of the support portion 37 provided on the side wall B2 surface of the storage box B, folded back, and folded back and connected by the hook-and-loop fastener 36 provided on the mounting belt (35) so that the mounting belt (35) itself is fixed. The mounting belt (35) itself is connected to the left and right or front and rear sides of the reinforcing device main body 2 so as to be arranged in pairs on the left and right, and can be inserted into the support loop 38 of the paired support portion 37 arranged on the side wall B2 surface and folded back in the same manner as the paired arrangement. In this way, the mounting belt (35) covers the bottom surface of the storage box B together with the reinforcing device main body 2 along the left and right or front and rear direction of the storage box B.

[0026] In the illustration, the support part 37 is provided on the handle fixing part 6 of the belt-like handle 5 arranged and fixed on the side wall B2 of the storage box B, but this is not limited to this. Also, although not shown in the illustration, it is also possible to connect the mounting belt (35) and the support part 37 with a male and female hook-and-loop fastener 36.

[0027] Although specific illustrations of the attachment means using hook-and-loop fasteners 16, 26, and 36 at mounting portions 15, 25, and 35, respectively, are omitted, they may also be, for example, magnets, hook buttons, hooks with a loop configuration, or other attachment means, and it is sufficient that mounting portions 15, 25, and 35 are attached and fixed to the lower part of side wall B2.

[0028] Next, an example of how these are used will be described. For example, the bottom reinforcement device 1 for a storage box according to the present invention can be attached and fixed to the bottom wall B1 of a storage box B, which can be folded inwardly, so that it covers the bottom wall B1 with the fastening means 10. If the reinforcement device 1 becomes damaged through use, it can be replaced with a new reinforcement device 1.

[0029] When installing the reinforcing device 1, the joint 11 in the fastening means 10 is joined by, for example, a male and female hook-and-loop fastener that is pre-installed on the bottom wall B1 of the storage box B, and similarly, by connecting it to, for example, hook-and-loop fasteners 16, 26, 36 or support loop 38 that are pre-installed on the lower part of the side wall B2 of the storage box B, the reinforcing device main body 2 is attached so as to cover the bottom wall B1 of the storage box B.
