A lid assembly for a refuse container includes a plurality of lid members, a pivotal attaching mechanism, and a cam-shaped lobe integrally formed on each lid member. The lid members each include a pivoting edge, a curved edge, and a surface complementary to at least a portion of an upper surface of the container. Each lid member includes a curved inner surface bound on opposing ends thereof by the pivoting edge and the curved edge. The pivotal attaching mechanism is adapted to attach the pivoting edges to the upper surface at a predetermined distance therefrom. The cam-shaped lobes are formed on the pivoting edge of each lid member and adapted to allow a pivotal motion of each lid member relative to the container and to contact the upper surface at a predetermined angle between the complementary surfaces and the upper surface, with the predetermined angle depending upon the predetermined distance and the shape of the lobes.

[ What is claimed is:] [1.] A lid assembly for a refuse container comprising:two lid members each including a pivoting edge, a curved edge, and a surface complementary to at least a portion of an upper surface of a container, each said lid member including a curved inner surface bound on opposing ends thereof by said pivoting edge and said curved edge;means for pivotally attaching said pivoting edges to the upper surface at a predetermined distance therefrom; anda cam-shaped lobe formed on said pivoting edge of each said lid member and adapted to allow a pivotal motion of each said lid member relative to the container and to contact the upper surface at a predetermined angle between said complementary surfaces and the upper surface, said cam-shaped lobes being formed such that said predetermined angle is determined by said predetermined distance, said cam-shaped lobes being formed such that said pivotal motion is limited to a range of motion between a closed position where said complementary surfaces are supported by the upper surface and where said curved edges substantially abut and an open position where said complementary surfaces form angles of less than 90 degrees with the upper surface.
