Abstract: A container includes a typically upright structure that may be disassembled by the release of locks. The locks include a system of upper forced wedging longitudinal locks that connect to adjacent edges of the top walls and side walls of the container. Forced wedging cuneiform side locks connect the minor or head side walls to the major top walls and side walls. A method of assembly/disassembly includes a series of stages by which the locks are removed, the top wall is removed, the container's head walls are disassembled, the side walls are lowered and all these walls are overlapped on the base wall until forming a flat structure. This flat structure may be mounted again in the opposite manner, until the container is upright and forms the load housing again.
