ABSTRACT:
A foldable container folded into its final configuration from a single flat blank of material having side walls and end walls hingedly connected together along their side edges, two similarly sized larger bottom panels hingedly connected to the side walls and two similarly sized smaller bottom panels hingedly connected to end walls. Each larger bottom panel is hingedly attached to one adjacent smaller bottom panel, such that when the side walls are erected from their collapsed state, the bottom panels fold down from their respective side and end walls to provide a continuous floor on the bottom of the container, the larger bottom panels having relief flaps which deflect about hinges as they strike each other upon descending to their open position. The blank is optionally provided with additional panels which are hingedly attached and may be folded so as to form inner side and end walls to produce a double walled container increasing the container strength. An integrated cover is also provided.
