Abstract
A stackable container lid for a bucket containing hot foods and the like comprising a generally circular lid having center portion surrounded by a series of polyhedrons, one plane of which extends upwardly at right angles from the lid surface thereby forming a perimeter into which the bottom of the bucket can be inserted. The lid may also contain vent holes in a rim on the outer perimeter of the container lid. The rim terminates in a downwardly extending lip adapted to snap over the top of the bucket in a sealing relationship.
