The invention relates to a waste container of the type typically used in residential waste collection systems. The waste container includes a container body having opposing side walls that extend upwardly from a bottom wall to form a waste compartment with an open top for access thereto. The bottom wall of the container body is reinforced by a series of corrugations to increase the rigidity of the bottom wall to prevent sagging, which can result in premature wear and failure. The corrugations also increase the heat transfer rate of the bottom wall, which improves the cooling characteristics of the waste container during molding. The corrugations further provide airflow channels for the injection of air between the container body and a mold during the molding process to improve the ease of removing the waste container body from the mold and to prevent stretching in the bottom of the container during the molding process.

[ What is claimed is:] [1.]1. A waste container for the storage and collection of residential or commercial waste, the waste container comprising:a body having a bottom wall with a peripheral edge and a peripheral wall extending upwardly from the bottom wall peripheral edge and terminating in an upper edge to define an waste compartment with an open top;a cover pivotally mounted to the body and moveable between an open position, in which the cover is remote of the open top to permit access to the waste receptacle, and a closed position, in which the cover overlies the open top to cover the same;a handle extending from the body near the upper edge of the body;a wheel assembly provided on the body near the bottom wall whereby a user can move the waste container by pulling or pushing on the handle to roll the waste container by the wheel assembly;an inner rib projecting downwardly from a bottom surface of the bottom wall; anda plurality of corrugations formed in the bottom wall and extending from the bottom wall peripheral edge to the inner rib wherein the corrugations and inner rib cooperate to form a structural support for the bottom wall.
