Abstract (en)
[origin: US5172821A] In order to keep opened bottles of sparkling wine fresh, a bottle closure device has been created which consists of a stopper which can be easily inserted and which sits without further manipulation in the bottle neck in a sealing manner so as to be axially displaceable. The device is also provided with a bracket retaining device which has upper and lower retaining fingers for holding the stopper and simultaneously engaging underneath the rim of the bottle neck. The stopper also has a gas injection bore with a non-return valve in order to inject freshness-retaining gas pressure.
