ABSTRACT:
A closure system is provided for a threaded container. A threaded closure cap has an annular skirt which engages a resilient gasket that is stretched over the bottle neck. The resilient gasket overlies a cap support flange which extends from the neck. Downward axial movement of the cap with respect to the container provides a vertical compressive force against the resilient gasket by the cap skirt. A heat shrinkable outer member surrounds the closure cap and provides a tamperproof seal with respect to the container.
