Abstract
A plastic stopper is used for small-diameter bottle necks such as are conventionally closed by corks. A top disk is annular in that a central hole is formed and below the disk is a pocket having an inside diameter coinciding with the central hole. The pocket is closed at the bottom. The pocket is dimensioned to receive a standard corkscrew with a tight enough grip to permit the stopper to be drawn. The disk also has a peripheral depending skirt having an outside diameter such that it fits tightly in the bottle neck. The lower outer edge of the skirt is tapered to facilitate seating. An annular space below the disk between the skirt and the pocket affords flexibility to the stopper for seating and pulling and also can be partially filled with liquid to reduce the amount of air in the headspace of the bottle.
