Abstract
The open end of a substantially cylindrical injection molded resilient plastic container, such as a paint pail, has a rim system integrally molded to the container wall to rigidify the open end of the container to facilitate filling the container using standard automatic filling equipment. An outer continuous rim and an inner discontinuous rim concentric with the outer rim are joined by a bridge member to form a substantially rigid rim system at the open end of the container. The rim system coacts with a closure lid to form a removable and resealable end closure on the container. Drainage or expulsion of fluid from between the inner and outer rims is provided for by drain openings or slots which make the inner rim discontinuous.
