ABSTRACT:
A molded lid for receiving a handle or the like is provided which may be molded of synthetic resin material in straight-pull injection molding machines. The lid includes a lid body presenting a top surface, a bottom surface and a circumscribing upright rim. A pair of opposed ears are tangentially oriented relative to the rim and define therebeneath a gap and therebelow a cavity. The gap is smaller than the cavity, so that a pin of a handle can be retained by the ears against passage through the gap. The gap between the ears enables the lid to be made by straight-pull injection molds so that the cavity-defining portion of the mold can pull through the gap so that the ears initially yield to permit the mold to pass therethrough and then return to their original, molded position.
