ABSTRACT:
A screw threaded cap for stoppering and re-stoppering of bottles enclosing gaseous beverages such as beer, has a base comprising a resilient lip adapted to co-operate with the junction of the bore of the bottle neck and its end surface. Ribs limit the distance between the latter and the corresponding surface of the base. The upper portion of the skirt has a rounded profile preventing cracks.
