ABSTRACT:
A container for a cream, gel, or the like, includes a bottle or jar, a top or primary cap, and a secondary or inner cover which is positioned over a top opening in the jar and compressed into sealing engagement therewith by the closure of the cap on the jar. The inner cover includes a resilient frusto-conical wall portion positioned between an outer rim a central hub. As the cap is threaded onto the jar, a top wall of the cap engages and depresses the hub of the inner cover, and flattens the frusto-conical wall which then exerts radially outward pressure on the rim to sealingly engage same with lip on the opening of the jar.
