Abstract
A collapsible shipping container comprising a base portion, three walls which are hinged to the base at their respective lower edges, a fourth wall which assembles to the base by sliding into a channel, four identical corner posts having a pair of channels for sliding on to the vertical edges of the four sides, and a top lid. The hinges on the side walls allow the three hinged side panels to fold over onto each other in a tightly layered configuration. The hinges do not carry a load which allows the containers to be stacked. The corner posts have locking pins which fit into holes on the tops of the walls to firmly lock the walls together. Skids are provided on the bottom portion to allow the container to be picked up and moved by forklifts. The top lid holds the corner posts and completely encloses the collapsed container. Alternatively, the container may accept snap-in casters on the bottom.
