Abstract
Abstract An improved cover and can assembly having a novel interlocking assembly comprised of a two "ball and socket" configuration thereby providing a greater surface or contact area between the cover or lid and the container. The novel interlocking assembly provides a snap-type closing which insures a tighter fit with far less chance of opening with the cover being provided with an annular groove including rib members located near the edge of the cover with the rib members providing means for separating the cover from the container.
