A nestable plastic container for handling and storage of bulk material such as food products is provided with three parallel, laterally spaced, downwardly extending hollow ridges forming supporting members. These ridges permit the use of a fork lift to handle the container. The ridges are hollow and open to the interior of the container but they may be easily cleaned by reason of the fact that they extend substantially the full length of the bottom of the container, and also by reason of the fact that they have a trapezoidal cross-section for easy access to their interiors. Specially designed ridges on the cover of the container receive one of the downwardly extending ridges of another container securing it against lateral motion, and thereby permitting safe stacking of multiple containers.
