Abstract

A molded closure for use with a container includes a top wall defining a generally planar inner surface and a skirt depending from the top wall generally perpendicular thereto. The skirt includes a container engaging member formed therein. The closure includes a retaining projection formed in the top wall contiguous with the inner surface and extending therefrom inwardly of the closure. The projection extends from the surface perpendicular thereto and defines at least a pair of mold binding surfaces perpendicular to the top wall surface. The binding surfaces are formed in facing relation to one another. The closure is formed in a heated state, and as the closure cools, at least the binding surfaces exert a binding force on the mold block at a location forming a part of the projection to momentarily retain the closure bound to the molding apparatus.
