ABSTRACT:
A disposable plastic lid for a container includes a generally round closure wall and a depending peripheral skirt for engagement with the container. The closure wall includes an improved stacking facility by which a plurality of such container lids may be stacked one on top of the other in a manner which precludes the stacked lids from being jammed together. The stacking means also retards materially any tendency for the lids in the stack to slip sideways with respect to each other which provides a very stable stack without supplementary supports.
