Description

[Detailed Description of the Invention] The present invention relates to an assembled container made of synthetic resin foam, etc., which is mainly used as a heat-insulating and cold-insulating container for packaging foods and the like.

Containers made of synthetic resin foam that are used as thermal/cold containers for packaging various foods or as transportation boxes usually have a container body that is made up of a bottom and four side walls that are integrally formed. In this case as well, the container must be handled in its bulky state, and there is a drawback that the efficiency of transporting the empty container is poor when transporting the container from the manufacturer or returning the container from the destination. Further, the deeper the container body is, the larger the molding die becomes, which increases the cost.

In view of the above, the present invention is designed so that the front, left, right and left side walls and the top and bottom bottom bodies and lid bodies are formed separately and can be easily assembled using fitting means, and when not in use, each part can be assembled separately. It was designed so that it can be disassembled and handled in a compact and low-bulk state, is extremely suitable for transporting empty containers, and is easy to mold and can be manufactured at low cost.
