Abstract: A removable thermoplastic cap for a beer keg bushing comprising a flat disc with integral peripheral skirt which includes inturned upwardly directed gripping lugs preventing removal of the cap when once fitted to a beer keg bushing, vertical slots spaced around the skirt and extending partway across the disc to provide venting for the interior of the bushing, and a pull tab provided on one side of the disc and connected by weakened lines to the opposite side thereof to facilitate peeling off of the cap by tearing apart the skirt.

Abstract: A resilient ring is fitted over a shoulder and onto the bail band indent of a bottle by an apparatus having means for supporting and locating the resilient ring, means to locate and align the bottle with the ring, and ram means for relatively displacing the ring and bottle to force the ring over the shoulder of the bottle, the ring support means engaging the shoulder of the bottle under radially inwardly directed biassing forces while supporting the ring as it is deformed to pass over the shoulder means. Preferably, the support means has a multiplicity of circumferentially spaced jaw elements displaceable under spring biassing in respective guides.
