ABSTRACT:
There is provided a new and useful removable lid, particularly adapted for commercial sized containers of the type which holds oils, grease, bulk food stuffs and the like. The lid comprises a central lid area which has parallel upper and lower surfaces. A continuous channel extends about the periphery of the lower surface. The channel has inner and outer walls for releasably receiving therebetween the upper lid of a container. A skirt downwardly depends about the periphery of the lid area. The skirt forms part of the outer wall of the channel. Means at the bottom of the channel act as a seal between the lid and the container when the lid is in position on the container. In the present invention, the upper surface of the lid area is unindented, from the center of the lid to its periphery so as to provide no relatively lowered surface areas within which liquids could collect on the upper surface, and spaced reinforcing ribs extending from the inner wall inwardly on the lower surface to reinforce the lid area for supporting a stacked container thereon and to reinforce the inner wall of the channel.
