Abstract
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.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
283 words
A stopper comprising, a hollow, generally tubular body adapted to be inserted into the mouth of a bottle neck, said hollow body being closed at one end and having an open end, said hollow body having a generally cylindrical inside surface, tapering outward toward said open end, and only five circumferentially spaced, axially-extending grooves in said inside surface extending from adjacent the closed end to the open end providing flexibility for said stopper whereby said stopper is less likely to be forced out of said bottle mouth, said body having a generally cylindrical first outside surface adjacent said closed end and a second generally cylindrical outside surface joining said first said surface, and a third outside surface extending from said second outside surface to the open end of said hollow body, said first outside surface tapering slightly inwardly and toward said open end, said second outside surface being cylindrical and said third outside surface tapering inwardly and toward said open end at a greater angle than said first outside surface, said grooves having relatively flat bottoms and relatively flat side edges, the depth of said grooves increasing from said open end toward said closed end, the wall thickness of said body at said grooves adjacent said closed ends being between 0.027 inches and 0.100 inches and said grooves adjacent said open ends being approximately 0.020 inches deep and are approximately 1/8 inch wide, said hollow body having a flange supported thereon concentric to said hollow body at said closed end, cylindrical flange extending generally concentric to said hollow body and spaced outwardly therefrom and adapted to receive the end of the neck of the champagne bottle between said flange and said hollow body,
