ABSTRACT:
A bottle stopper made of plastic material having a hollow, tubular, generally cylindrical body closed at one end with axially extending grooves molded in the inside. The grooves extend approximately 2/3 of the way through the wall of the hollow, tubular cylindrical body, providing flexibility for the stopper to make it fit better into the neck of the bottle and maintain pressure and allow easier capping and easier removal and greater security of the bottle.
