2. Description of the Related Art Conventionally, for example, a foldable body is formed of corrugated cardboard having a three-layered structure, and a transport container is formed by closing upper and lower openings of the body with a pallet made of synthetic resin. , Utility model registration No. 30166
No. 31, gazette is proposed. The body of the transport container can be bent by slightly compressing (crushing) the corrugated board as a material in the thickness direction at a position where the corrugated board is formed. The carrier container made of corrugated board is lightweight and has an advantage that it can be incinerated and discarded after use.

However, since such corrugated board is inferior in strength, durability, water resistance and the like, it has been practiced to form the transport container using a hollow structure plate made of synthetic resin. This synthetic resin hollow structure board is also generally called "plastic corrugated board", and a plurality of parallel ribs are provided between opposed synthetic resin flat plates to provide a plurality of space sections partitioned inside. It is a thing.

By the way, in order to make a transport container foldable using the above-mentioned plastic corrugated board, it is necessary to form the plastic corrugated board itself so that it can be folded. A method of folding a plastic cardboard is proposed, for example, in Japanese Patent Laid-Open No. 6-340015 and Japanese Utility Model Laid-Open No. 7-28012.

[0005] Japanese Patent Laid-Open No. 6-340015, Fig. 1
As shown in FIG. 2 , one of the flat plates 101 constituting the plastic corrugated board 100 is scored and the other flat plate 1 is cut.
A structure in which 02 is folded to have a folding structure is disclosed.

[0006] Japanese Patent real-Open No. 7-28012, FIG. 13
As shown in, heat the iron with a plastic cardboard 103
It is disclosed that a groove 104 having a V-shaped cross section is formed by melting a part of the groove and the bottom wall 105 of the groove 104 has a bent structure.

Since the transport container formed by using such a hollow structure plate is foldable, it can be returned in a folded state when the article is reused after being transported. Therefore, compared with the case where the transport container is not folded and returned in an empty state, the volume is smaller, and thus the transport cost can be significantly reduced.

[0008]

However, the above-mentioned carrier container has the following problems. First, since a carrier container having a body made of corrugated board is inferior in strength to a carrier container having a body made of plastic corrugated board, the bent portion of the corrugated board is rubbed and thinned by repeated use, and it is easy to tear.

Further, in order to increase the strength of the transport container, it is necessary to increase the thickness of the corrugated board forming the body, but on the other hand, it becomes difficult to compress (crush) the corrugated board at the position of the bent portion. It becomes difficult to bend the cardboard. Therefore, it becomes impossible to form a foldable body.

On the other hand, in the transport container formed of plastic corrugated cardboard, as shown in FIGS. 12 and 13 , since the bent portions are almost connected by a single flat plate, they may be closed and opened many times. , The hinge part was broken (cuts were formed) and could not be used repeatedly for a long time.

Therefore, the present inventor has completed the present invention as a result of intensive studies to obtain a connecting structure in which the connecting portion is less likely to be damaged even if it is repeatedly used.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a connecting structure in which plate-like constituent members are foldably joined, a container body using the same, and
