ABSTRACT:
A container assembly having a cylindrical container body and a substantially circular container lid is provided with inwardly extending annular reinforcing ribs on an inner surface of the container body in the region of the mouth thereof and with angularly equispaced radially extending reinforcing ribs on the container lid extending from a V-shaped annular channel at the periphery of the lid substantially to an indented circular area at the center thereof. Closure of the lid to the body is effectuated by means of a pair of longitudinally spaced annular shoulders on an inside surface of the container body and a pair of complementary annular lips on the container lid, as well as a third annular shoulder on an outside surface of the container body and a corresponding annular lip on the container lid. One of the inner shoulder surfaces on the container body is disposed in substantially the same transverse plane as the annular shoulder located on the outer surface of the container body.
