US Patent 7195127 Collapsible container

The collapsible container includes a plurality of side walls connected via hinges to a base. The side walls are moveable about the hinges between a collapsed position on the base and an upright, use position generally perpendicular to the base. Each of the hinges includes a hinge pin rotatably received within a hinge receiver. Each hinge pin includes at least one radial projection that abuts a portion of the hinge receiver when the side wall is in the upright position. The radial projection resists over rotation of the side wall and prevents the hinge pin from leaving the hinge receiver during the application of an over rotation force.
