ABSTRACT:
The present invention pertains to a safety closure for a sparkling wine bottle which closure comprises a specially constructed cork member having a head portion, a base portion and a stem or shank portion interposed between said head and base portions with the base portion being provided with gas pervious means to permit the passage of pressurized gas from beneath the base portion, past the shank portion and then outwardly of the opening in the neck of the bottle. The foregoing is the structure by which the pressurized gas is safely and effectively dispelled from the bottle while concomitantly providing the aural popping associated with the opening of a bottle of sparkling wine but preventing the forcible propulsion of the cork member outwardly of the bottle, due to the frictional engagement of the base portion with the neck of the bottle.
