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 .
