Abstract

A one-piece hygienic cap to close the neck opening of an inverted liquid container has a lid portion to overlie and sealingly close the container opening and an annular skirt portion extending axially away from the lid to surround a portion of the container neck. The lid portion is provided with an axially inwardly extending recess including an outer sleeve and an inner plug portion integrally formed with a frangible connection therebetween. The cap cooperates with a probe dimensioned for insertion into the recess for breaking the frangible connection and separating the plug portion from the sleeve to permit the discharge of liquid from the container. When the probe is withdrawn from the recess, the plug portion is drawn into the sleeve to close the recess and reseal the container.
