ABSTRACT:
A closure for a cylindrically shaped ice cream carton or the like includes a unitary circular shaped plastic lid provided with a depending skirt portion. The top surface of the lid includes an upwardly and inwardly extending concentric bead inwardly tapered on its outer surface to enhance retaining a plurality of similar lids in stacked relation. The bead rigidifies the lid, enhances nested stacking of lid-carton assemblies and provides a locking and protective recess for labels containing printed indicia. The skirt of the lid includes a lower outwardly tapered inner surface portion for mating with the outer surface of the bead to enhance nested stacking of the lids and to enable the lid to be grasped and readily removed from tight fitting engagement with an ice cream carton. An upper, inner annular recessed portion of the lid skirt accommodates expansion of the ice cream carton without the lid popping off the carton. The plastic injection gate is recessed in the top surface of the lid to protect the label and the base of a carton stacked thereon.
