ABSTRACT:
A collapsible material handling container comprising a deck bed having a plurality of support legs thereon, and a deck mat fixed to the upper surface of the deck bed. A first side wall is hinged along the lower edge thereof to the deck mat, and a pair of opposed end walls are hinged along the front edges thereof to the opposite side edges of the first side wall. A second side wall is hinged along the lower edge thereof to the deck mat. In the erected condition of the container, the second side wall is connectible to the end walls by releasable lock mechanisms. The upper portion of the first side wall may comprise a gate having a releasable lock mechanism which coacts with the end walls for connecting the gate to the walls, in the erected condition of the container. The hinges between the first side wall and the end walls extend vertically along only the lower portion of the first side wall. When the container is to be collapsed, the locking mechanisms associated with the second side wall are released, and the opposed end walls are individually and sequentially folded inwardly to overlap the first side wall. The second side wall is then folded inwardly to directly overlie the deck mat and then the first side wall, with the end walls folded thereon, is folded inwardly to overlap the second side wall.
