A collapsible plastic container comprises a pair of side walls and a pair of end walls each of plastic material formed with a plurality of air-circulation openings therethrough; and hinges mounting each end wall between a pair of side walls to form a container in which the walls are hinged for movement either to an open condition or to a collapsed condition. Each of the walls includes internally-extending bottom ledges adapted to receive a bottom wall of plastic material formed with a plurality of air-circulation openings therethrough. The side and end walls are formed with cooperable tongue and slot retainer elements to retain them in their open condition until the bottom wall is applied to the bottom ledges.
