Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate-shaped material storage container, and more particularly to a plate-shaped material storage container suitable for storing an extremely thin plate-shaped material such as liquid crystal glass.

[0002]

2. Description of the Related Art As a storage container for plate-shaped materials
According to this, the storage container is composed of a rectangular parallelepiped box body and a lid body that fits into the top opening of the box body, and a plate is provided inside the box body side wall. Partitioning grooves for arranging the shaped members in parallel at a predetermined interval are formed at a predetermined interval.

[0003]

However, the storage container disclosed in Japanese Utility Model Laid-Open No. 64-37047 has a drawback that the size of the storage container must be changed every time the size of the plate-shaped material changes. Further, although such a storage container is usually plastic-molded using a mold, there is a problem that the mold has to be changed for each size of the storage container.

In addition, with the recent increase in the size of glass substrates for liquid crystals, a conventional storage container requires a large storage space. In particular, saving space when transporting empty containers is a major issue. The present invention has been made in view of the above circumstances, and an object thereof is to provide a plate-shaped material storage container that can be manufactured by a common mold even if the size of the plate-shaped material is changed. Another object of the present invention is to provide a storage container having a storage space for empty containers that is much smaller than the conventional one.

[0005]

In order to achieve the above-mentioned object, the present invention is formed in a substantially U-shape from first and second side walls and a back wall sandwiched between the first and second side walls. 2 units out of the 4 units
One unit is connected as a lower unit in an opposite position, and the remaining two units among the four units are connected as an upper unit in an opposite position and their lower edges are connected to the upper edge of the lower unit. A storage container having a rectangular parallelepiped shape is formed as a whole by being connected, and a partition groove for arranging plate-like materials to be stored in parallel at a predetermined interval is formed inside a back wall of a unit forming the storage container. Is characterized by.
