Abstract
Abstract A closure for a container which includes an impervious disc and can also include a resilient annulus overlying the mouth of the container. A retaining ring attached to the container adjacent the mouth having an inwardly directed flange overlies the disc and the annulus to hold the disc and the annulus firmly in assembled relation forming a seal with the mouth. A cap having a tubular spout with a pointed inner end perforates the disc to discharge contents of the container.
