A cap device, particularly for a wine bottle, is disclosed as including a cap having a recessed top opening for receiving a screw for threadable insertion into the cork of the wine bottle. The recess at the top of the cap is of basically square shape with two recess extensions for receiving a butter knife, or the like, for turning the cork and screw as a unit and thereby unscrewing the cap, which is threadably attached to the outside of the neck of the wine bottle. The threading direction of the threads of the cap and neck of the wine bottle are opposite to the threading direction between the cork and the screw. Additionally, the cap is structured to extend a distance above the extent of the cork in the neck of the wine bottle, the cork is bullet-shaped and channels are defined transverse to the threads extending outwardly of the neck of the wine bottle, in order to allow the escape of compressed carbon dioxide in a sparkling wine or champagne bottle as the cap is unscrewed and the cork lifted. The top of the screw defines a spherical projection in order to assist guiding the cork in, with respect to the recess of the cap, when reinserting the cork after use. |
