Abstract
The collapsible container includes a rectangular bottom wall, two opposed vertical side walls, two opposed vertical end walls, hinge means for pivotally and releasably attaching the side and end walls to the bottom wall, and means for locking the side and end walls in an erected position. The hinge means preferably includes a first wall having a first hinge portion with an integrally formed pivot pin adjacent a bottom edge and a second wall having a cooperating second hinge portion with an integrally formed, semi-cylindrical surface. Preferably the second hinge portion further includes an integrally formed projection disposed adjacent the semi-cylindrical surface spaced along a periphery of the second wall. The projection is movable out of axial alignment with the semi-cylindrical surface to permit insertion of the pivot pin and returnable into axial alignment with the semi-cylindrical surface to releasably secure the first wall in pivotal relation to the second wall. The corner joint locking means preferably includes the side wall having a groove formed on an exterior surface adjacent a vertically extending edge and the end wall having a flange extending generally parallel with the side wall. A second flange extends inwardly from the first flange and is engageable within the groove. A third flange having a surface generally parallel to the second flange engages a corner edge of the side wall with a ridge formed on the surface to releasably lock the side and end walls in the erected position.
