DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foldable and assemblable plastic storage box used as a transport box or a storage box.

[0002]

2. Description of the Related Art As a storage box that can be folded and assembled, a cardboard box assembled with corrugated paper is generally used. A plastic container which can be folded by folding both side surfaces inward from the center, and a box which is folded by connecting each surface of the box with a hinge or a metal fitting having flexibility. There is also known a plastic box or the like having an upper surface opened so that it can be viewed only.

[0003]

Of the above-mentioned storage boxes, the cardboard box is relatively easy to fold and assemble, and can be folded flat so that it is not bulky. Although it has the advantage of being relatively inexpensive to manufacture, it is susceptible to water and moisture, and is inferior in strength, so the items to be stored are limited, care must be taken in handling, and it is liable to be damaged during transportation, limited to repeated use, At present, they are discarded after being used several times, and there are difficulties in durability. Also, discarded cardboard boxes are often incinerated, and the rate of recycling and reuse is low.

[0004] On the other hand, plastic containers and boxes are more resistant to water and moisture and have higher strength than cardboard boxes, so that the number of items to be handled increases, damage during transportation is reduced, and the frequency of use can be increased. Since the bent part is usually bent at room temperature, the bent part is likely to be deteriorated during processing and the strength tends to decrease, and there is a possibility that it will be damaged from there, and it will be folded flat like a cardboard box. Difficult to fold, especially when connected with hinges or metal fittings, these may interfere with flat folds, bulky, and lids are often separate things, and can be folded together. The conventional plastic storage box has drawbacks such as the fact that different materials such as metal fittings are used in each place, so when it is recycled and reused, it is necessary to separate and sort the materials. .

An object of the present invention is to provide a plastic storage box which can be easily folded and assembled, can be folded flat when folded, and has excellent strength and durability. What you want to do.
