Abstract
A cover for a waste can has three elements: a collar; a lid; and a spring link, so-named because it functions both as a linkage between the collar and the lid and a spring for biasing the lid closed. Three modes of operation are made possible by the location of a pair of parallel pivot axes, one between the lid and the spring link and the other between the spring link and the collar. The collar is friction fit on any suitably sized receptacle.
