Abstract:
1. A reusable container comprising a container bottom and side walls that are attached thereto in an articulated manner and can be folded down in the direction of the container bottom, so that the side walls can be folded down onto the container bottom for transport and storage when the container is empty and locked to each other when they are in the upright position, wherein interlock devices on at least one side wall comprise a pressure lever that can be folded down in a direction towards the container bottom, the pressure lever being provided with a locking hook that, when the side walls are in the upright position, overlaps with a locking hook of a locking catch on the side wall adjacent to the at least one side wall in order to interlock the side walls, wherein the locking catch in the side wall includes spring-like elastic characteristics and locking protuberance that projects inwards from an interior face of the adjacent side wall as to assure that the locking catch will build up an elastic return force when it is pressed outwards due to rotation of the pressure lever.
