DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. First, in FIG.
Are formed in a cubic shape in which the sides of the five surface portions 2 are connected to open the upper surface. The surface portion 2 has a substantially square shape and is formed of a bendable member, for example, a fabric made of a natural fiber or a synthetic fiber, a mesh member having air permeability and water permeability, or a plastic film or the like. I have.

A vertical ridgeline 12 formed by each side 11 at the upper end of the box 1 and the two surface portions 2 and a ridgeline 1 at the bottom surface
3 is connected to a reinforcing member 14 made of a plastic or metal pipe or rod, which imparts rigidity to each. In this embodiment, the side 11 and the ridge 1
A tubular portion 15 is formed by sewing or welding on the members 2 and 13, and the reinforcing member 14 is inserted therein. The length of the reinforcing member 14 is shorter than the length of the side portion 11 and the ridgelines 12 and 13,
The corresponding edge angles A, B, C, D, E, F,
An interval 16 exists between G and H.

At each ridge angle A, B, C, D, E, F, G, H, a T-shaped universal joint 21 is attached. This is made of a bendable natural fiber or synthetic fiber cloth, and is attached to the surface 2 in contact with each ridge, and connects the ends of three opposing reinforcing members 14. . In this embodiment, a tubular portion (not shown) is formed at each end of the T-shape, and the reinforcing member 14 is inserted therein. Further, both ends of a band-shaped member made of a bendable material, for example, a natural fiber or a synthetic fiber are attached to opposing side surface portions 2, and a pair of annular handles 22 (only one is shown) are attached. Have been.

Next, a procedure for folding the box 1 will be described. In the case of folding, the diagonal line of the surface portion 2 is folded in two. a, when the ridge angle A is moved in the direction of the arrow from the use state shown in FIG. 2 to overlap the ridge angle C, the state shown in FIG. 3 is obtained. b. Next, when the ridge angle B and the ridge angle D are moved in the arrow direction from the state shown in FIG. 3, and the ridge angle E overlaps the ridge angle B and the ridge angle D, the state shown in FIG. 4 is obtained.

C, the ridge angles F and H from the state shown in FIG.
Are moved in the direction of the arrow and overlapped, the state shown in FIGS. d, when the ridge angle G is moved in the direction of the arrow from the state shown in FIG. 6 and the ridge angles B, D, and E overlap, the state shown in FIG. 7 is obtained.

E, when the ridge angles F and H overlap the ridge angles A and C from the state shown in FIG. 7, the state shown in FIG. 8 is obtained, and all the reinforcing members 14 are arranged in parallel. It is folded into a triangular shape with the member 14 as the base. f, Then, if the handle 22 is wound on the back side beyond the vertex of the triangle, the state shown in FIG. 9 is obtained, and the box 1 is restrained from being unfolded. g, When the box 1 is used, the winding of the handle 22 may be released, and the box 22 may be assembled in a cubic shape in the procedure opposite to that described above.

According to the above embodiment, the following effects can be obtained. 1, since the reinforcing member 14 is connected to the upper side 11 and the ridgelines 12 and 13 of the box 1, in use, it stands up with its upper surface open. Therefore, when storing the articles in the box 1, it is not necessary to support the box 1 by hand, and the articles can be operated using both hands, and the handling is easy. 2, and furthermore, since the free joints 21 are provided at each ridge angle to connect the continuous surface portion 2 and the three reinforcing members 14, the box 1 can be folded small while the reinforcing members 14 are in contact with each other when not in use. It is easy to carry and store. Also, since the reinforcing member 14 is not removed, unlike the conventional example, there is no risk of loss.

[0015] The folding procedure is simple because the folding may be performed along the diagonal line of the surface portion 2. 4. If the material of the face portion 2 is made of a gas-permeable or water-permeable member, it can be used instead of a water tank for chilling beer or fruit by dipping in water or for holding small fish. 5. If a water-tight member is used as the material of the surface portion 2, it can be used as a container for storing water, such as a tank. 6. If box 1 is folded and handle 22 is wound, box 1
Because it does not spread, it is convenient for transportation.

[0016]

According to the present invention, a cubic box formed by connecting five bendable surface portions and each having an open top surface is formed by each side portion and two surface portions of the upper end portion of the box body. To the corresponding ridge line, with a space between the corresponding ridge angle, a reinforcing member for providing rigidity to the side and the ridge line, and attached to a surface portion located at each ridge angle and in contact with the ridge angle. With a flexible joint that connects between the three reinforcing members,
When the box body is not used, it is folded along a diagonal line of each surface portion so as to be folded into a triangular shape in which all the reinforcing members are arranged in parallel. It has an excellent effect that it can stand alone in a folded state and can be folded small when not in use.

Further, since the material of the surface portion is made to be air-permeable and water-permeable, there is little resistance even in the river, so that it can be carried when fishing, and the water tank can be used and the fish can be used instead.
Furthermore, if the handle is wound around the box, the box does not expand during transportation, which is convenient for carrying.
