Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a box-shaped container for storing an item.

[0002]

[Prior art]

 Most conventional plastic containers are molded using a mold. However, in the case of mass production, it is advantageous to use a mold, but in the case of small volume production, using a mold results in high cost.

[0003]

[Problems to be solved by the device]

 An object of the present invention is to provide a box-shaped container which can be easily manufactured at a low cost by a simple processing method without using a mold.

[0004]

[Means for Solving the Problems]

 The above-mentioned object is according to the present invention, namely, a box main body 1 in which a plurality of orthogonal planes are continuously and integrally formed by bending a single amorphous polyester sheet, and the box main body 1 Box replenishing plates 2 and 3 made of the same amorphous polyester sheet and arranged at the open surface and joined to the box main body 1 by any means such as screws 4, rivets, and adhesives. It can be achieved by a box-shaped container consisting of.

【Example】

 Hereinafter, the illustrated embodiment of the present invention will be described. First, in FIG. 1, reference numeral 1 is a box main body portion, reference numerals 2 and 3 are box body supplement plates, and reference numeral 4 is a screw. The box main body 1 and the box replenishing plates 2 and 3 are both amorphous polyester sheets, for example, commercially available from Tsutsunaka Plastic Industry Co., Ltd. under the name "Sanroid Pet Ace (registered trademark)". Made of PET (polyethylene terephthalate).

The box body 1 is composed of a front plate 5, a bottom plate 6 and a rear plate 7. As shown in FIG. 4, at first, the box body 1 has a flat plate shape as punched from a single material sheet. ing. It should be noted that joint pieces 8 are provided on the outer sides of both ends of each plate, and screw holes 9 are formed in the joint pieces 8. Then, as shown in FIG. 3, the front plate 5, the bottom plate 6, and the rear plate 7 are bent so as to be orthogonal to each other to form a three-dimensional shape, whereby the box main body 1 is formed. Further, each joining piece 8 is also bent so as to be orthogonal to each plate. It should be noted that if the bent portion, that is, the boundary portion of each plate or the boundary portion between each plate and the joint piece is made thin, the bending is easy.

Next, the two box body supplement plates 2 and 3 are also made of the same material as the box main body 1. As shown in FIG. 4, the box body supplement plates 2 and 3 are formed by punching together with the box main body 1 from a single material sheet. The box replenishing plates 2 and 3 are flat and need not be bent. However, a screwing hole 10 is formed in the peripheral end portion.

As shown in FIG. 3, the box main body 1 has left and right side surfaces open. The box replenishing plates 2 and 3 are arranged on the open surface of the box main body 1 to close it. The box replenishing plates 2 and 3 are brought into contact with the inner surface of the joining piece 8, and fixed to the box main body 1 by tightening the nuts 11 with the screws 4 that are inserted into the screwing holes 9 and 10 of both sides. And the completed state is shown in FIG. The means for joining the box body supplement plates 2 and 3 to the box body main portion 1 is not limited to the screw 4 described above, and other rivets or adhesives may be used.

[0009]

[Effect of device]

 The present invention is as described above, and the box main body 1 can be formed only by bending the material sheet, and the box main body 1 is joined to the box replenishment plates 2 and 3 to complete the invention. Since it can be processed, it is easy to process, and since an amorphous polyester-based sheet is used as a material, it has advantages that it can be easily bent or drilled, has good workability, and can be manufactured at low cost. Therefore, in the case of small volume production, it is more cost effective than using a die. Moreover, since it can be formed mainly by bending, it can be assembled on site, which is advantageous for transportation and the like. In addition, since it is made of an amorphous polyester sheet, it is strong and durable, and it is also suitable to decorate its surface by engraving or printing, so it can meet various needs. , High usefulness.
