Abstract
A stackable container, including side walls extending upwardly from a bottom wall and defining an open-top, enclosed space therein, and rigid support members spaced about the bottom wall, the rigid support members having a vertical height. The side walls are tapered outwardly so as to be stackable in a nesting relationship within a similar container with a stacking offset less than the support members vertical height whereby the support members are supported on aligned rigid support members of the similar container. Outwardly tapered stress-relieving triangular corner surfaces extend upwardly between 130° and 140° from corners of the bottom wall and connect to side walls to form each junction of the bottom wall with two side wall. A lid has a rim adapted for placement around a container rim, with inwardly projecting flanges on each of the lid rim sides whereby the flanges extend beneath a downwardly facing portion of the container rim adjacent each of the four walls to releasably secure the lid to the container rim.
