A plastic nesting and stacking case in the form of an open-topped integrally molded rectangular unit having a pair of first opposed side walls, a pair of second opposed side walls and a bottom wall, comprises an upper part with its walls normal to said bottom wall, an intermediate part slightly tapering inwardly and having a height equal to a substantial fraction of the height of said upper part, and a lower part having a height equal to said upper part and tapering slightly inwardly towards the bottom wall of the case. The upper edge of the lower part has an outwardly projecting flange, whereby to enable partial nesting of a first case in a second similar case by the flange of the former resting upon the top edge of the latter. A pair of retractible supporting frames rotatively mounted upon the top of the cases serve to enable stacking of a number of cases with the bottom wall of one case resting upon the supporting frames of the case below in the stack.
