Abstract
The present invention describes a bottle closure for bottles containing liquids at high pressure, such as bottles of sparkling wine, the closure having a first part and a second part, the first part having a portion adapted to receive a portion of an upper section of a neck of the bottle, and a second part that fits substantially over the first part, which is relatively movable with respect to the first part and has at least two positions, a first of which is in a free position and a second of which is in an interlocking position whereby a portion of the second part urges against a portion of the first part receiving the upper section of the neck of the bottle so as to be engaging against an outer side of the said first part to hold it thereby to resist release from its interlocking position with respect to the said neck of an industry standard bottle.
