DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a pruning operation, a weeding operation,
Harvesting of fruits and vegetables, collection and cleaning of empty cans,
The present invention relates to a box-shaped container such as a container for holding a liquid, and in particular, this box-shaped container can be easily opened independently when used, and can be easily folded when not used, and is an optimal container for storing and transporting. In addition, if a net with air permeability or water permeability is used for the box body, stored plants and garbage can be dried, and washing after empty spills such as empty cans is easy. The present invention relates to a self-supporting openable and foldable box-like container that can be made into a highly water-tight sheet-like body, or becomes a highly water-tight box-like container.

[0002]

2. Description of the Related Art As conventional storage and transport equipment, square or round cloth or plastic sheet baskets and box-shaped transport equipment made of mino, square or round plastic molded articles are used. Some products cannot be folded at all, or they can be folded like plastic molded products, but they need time to assemble to make them self-opening, and those made of cloth or sheet can open themselves somehow when new. However, the shape was deformed by a small stress, and it was difficult for the self-standing opening to occur.

[0003]

In such a conventional storage and transport device, since it does not open independently when used, it takes time and effort to make it open, and it requires human labor to fold it after use or it cannot be folded. In such a case, there is a problem that the space becomes bulky and space is required for storage and transportation. In particular, since there is no net box with a self-supporting opening and folding function,
It often took a lot of time, space, and was very difficult to store plants and plants in the same container and dry the stored items. Furthermore, in the case of work in the rain, there is a problem that the drainage is poor, and the contents remaining in the can such as an empty can overflow and overflow, and the contents are accumulated in the container and cannot be washed, so that it is very inconvenient to use. In addition, there is no water-tight box-shaped container that can be folded independently,
In many cases, it is inconvenient to take a lot of space for transporting the box itself and to make it difficult to inject liquid when it is not self-opening. Further, when the box-shaped container is large, particularly when it is wet with rainwater or the like, there is a problem that the side-surface independent strength at the time of the self-opening opening is lost, and the container easily falls down.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and comprises a box-shaped container made of a flexible sheet and a rod, so that it can be used at the time of use. It is an object of the present invention to provide a box-shaped container in which a folded box-shaped container is quickly opened in a self-supporting state, and can be easily folded when not in use, requires a small storage space, and is easily transported.

The procedure for folding the box-like container and opening it independently will be described in detail with reference to FIGS. 1, 2 and 3. FIG. 2 is a perspective view showing a state where the box-shaped container shown in FIG. 1 is turned upside down, and FIG. 3 is a perspective view showing a state after it is folded. First, when folding, turn the box-shaped container upside down as shown in Fig. 2 and use the four ridges on the bottom of the box-shaped container.
When the diagonal line connecting the vertices 13b and 13d is folded inward, both side surfaces of the box side surface, on which the lateral side reinforcing rods 4 are provided, are pressed so as to be twisted exactly 90 °, and the rod shape is formed. Both diagonal lines connecting the vertices 13a, 12b and 13c, 12d on both sides where the body 4 is not provided are folded inward and folded as shown in FIG. On the other hand, when the box-shaped container is to be opened by itself, it is folded at a right angle by twisting the right and left sides of the side reinforcing bars 4, 4 shown in FIG. Ridge (12a-12b-
12c-12d-12a) is horizontally opened, the bottom surface is also spread horizontally, and the side surfaces are also at the same time, and all the side surfaces are perpendicular to the opening surface, and are in a self-standing state. Since the rods 2a and 2b at the respective ridges of the opening surface are fixed in this way, and the rods 4 and 4 are fixed laterally at the center of the side surface of the box, the toughness of the rods 2 and 2 makes the opening surface Each side surface can be formed in a box-like body while keeping the spread properly.

[0009]

Embodiment 1 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the present invention. As the sheet body 1, a cross-woven pattern fabric of polyethylene long fiber (trade name: Kowa Screen K1500) is used, and the side and bottom are sewn in a cubic box shape. To form a box. In each of the two ridges (four ridges) of the upper surface opening, a tough and highly deformable upper surface opening rod in which a thin FRP pole is sealed in a polyethylene tube.
Shape 2 (the elastic bar 2a for upper surface opening)
And sewed and fixed to the sheet body 1. The joiner 10 is a ribbon-shaped sheet (trade name: Hi-P U sheet) in which both sides of a plain weave of polyethylene filament are laminated with polyethylene. Further, on the other opposed two ridges of the upper surface opening, a rod-shaped body for upper surface opening made of a thick FRP pole having rigidity.
2 (the rigid bar 2b for opening the upper surface) is sewn and fixed to the sheet 1 so as to be wrapped with the joiner 10 in the same manner as described above.

Further, on the four ridges of the side surface of the box, the above-mentioned elastic rod-like members 3 (3a, 3b, 3c, 3
d) is sutured and fixed vertically. Also, the side reinforcing rods 4 are joined sideways to the center of the two opposite sides of the side face to joiner 10.
Fix with suture. The side-reinforcing bar 4 may be the above-described rigid FRP pole or a highly tough highly deformable elastic bar. In any case, at the time of folding, it is only necessary that the opposing side surfaces are fixed to the center of each of the two surfaces that are not folded diagonally, and that the side surfaces can be maintained in a state where they are not bent.

Further, in the present embodiment, the belt 9 woven from polyester fibers is used as a lifting material that can withstand the lifting strength so that the storage capacity is large because the box volume is large and the lifting by mechanical force can be performed. The belt 9 also serves as a joiner for fixing the rod-shaped body 3 for each ridge on the side surface. That is, as shown in FIG. 1 and FIG. 2, the rod-shaped body 3a is sewn and fixed as a joiner so as to wrap the rod-shaped body 3a upward from the position of the point A of the ridge on one side, thereby forming the upper lifting upper belt 9a. The rod-shaped body 3b is stitched downward as a joiner so as to enclose the rod-shaped body 3b, and the lower lifting lower belt portion 9b is formed on the diagonal line on the back side of the bottom surface.
Is sewn upward as a joiner so as to enclose it, an upper lifting upper belt portion 9c is formed, and a lower joining lower belt portion 9d is sewn and fixed as a joiner downward so as to wrap the rod-shaped body 3d. Similarly, it is formed on the diagonal line on the back side of the bottom surface, and is finally sewn and fixed as a joiner up to point A so as to surround the rod-shaped body 3a. Furthermore,
When the weight of the stored item is large, as shown in FIG. 2, the rope 11 is attached in a loop shape to the intersection of the lifting belt on the lower side of the bottom surface so that the machine can be easily lifted by a forklift or the like.

In order to construct the box-shaped container as shown in the first embodiment, there is another net body as the flexible sheet body 1, which is knitted with nylon, polyester, polyethylene, polypropylene or the like. Nets, cross-woven fabrics,
Laminated nets such as Russell nets and knit nets, high-strength woven fabrics such as plain woven fabrics and tents of polyethylene filaments, and plain or heat-set non-woven fabrics such as polyethylene and polypropylene are laminated with a film such as polyethylene. A single plastic film may be used as long as it can be used as a component of a box-shaped body, such as a sheet-shaped body, and has strength.

A net-like material is required if air permeability and water permeability are required depending on the purpose of use, and a laminate sheet or film-like material is preferred if water tightness is required. The material may be selected in consideration of the strength of the constituent material according to storage or light weight storage. If the bottom surface of the box is required to have a high wear resistance, a material having a high wear resistance such as a woven pattern fabric of long fibers made of polyethylene is used on the surface, and a Russell made of long fibers made of polyethylene is used on the side surfaces. Combinations of materials such as nets may be used.

In order to form a box shape, a net-like or cloth-like material is preferably sewn. In the case of a coarse net, a ribbon-like sheet or woven fabric is meshed. If the suture is passed through the stitch, the suture strength can be increased. In addition, in the case of a sheet-like material in which a filament such as polyethylene is plain-woven or a non-woven fabric (the product name: Nisseki Warifu), etc., laminated with a polyethylene film, or in the case of a thermoplastic plastic film, it is joined by pressurized thermal bonding. You can also.

As the rods for opening the upper surface and for the side surfaces, in addition to the above-mentioned FRP poles for vinyl houses, those having high rigidity such as metal rods, metal pipes and vinyl pipes with high elasticity, and conversely, As the material having flexibility or elasticity, polyethylene foam, polyurethane rubber, or the like may be formed into a square, round, or tube shape. Particularly, a gas is sealed and sealed in a flexible polyethylene tube, a soft vinyl chloride tube, or the like. By encapsulating and sealing a thin FRP ball, metal rod (piano wire), etc., rich in elasticity in the above-mentioned tube, a rod-like body rich in toughness and elasticity can be obtained. One of the opposing two ridges is a highly rigid rod 2b for increasing the tension on the side of the box, and the other is a highly elastic rod 2b. By using in combination as a sheet, a heavy object is stored in the box, stress concentration caused when the tips of these rods come into contact with each other even when they are repeatedly transported is reduced, and the sheet fixing the rods is used. It is possible to protect the body 1 and the joiner 10 shown in FIG.
