ABSTRACT:
A threaded bottle stopper for controlling the release of pressurized gases from a bottle is disclosed. The threaded bottle stopper is used in conjunction with an externally threaded bottle neck and comprises a cap having an internally threaded annular skirt depending downwardly therefrom and a tubular body portion extending downwardly from and integral with the underside of the cap. The outside diameter of the tubular body portion is such to permit insertion thereof within a neck bore of a bottle. The continuous thread on the annular skirt engages a continuous thread on the neck of the bottle where rotation of the threaded stopper in both directions moves the tubular body portion respectively into and out of the neck bore of the bottle. The bottle stopper is provided with means for sealing the discharge opening of the bottle neck. The tubular body portion of the stopper has gas release means on the outside surface thereof for controlling the release of pressurized gases from the bottle by providing at least one open-ended tortuous channel through which the pressurized gases pass before escaping to the atmosphere. The gas release means releases pressurized gases from the bottle while the threaded stopper engages the threaded bottle neck. The threaded bottle stopper provides a mechanical means for removing a stopper from a bottle containing carbonated beverages where the release of pressurized gases is controlled to preclude spillage and ejection of the stopper at a high velocity when the bottle is opened.
