Claim:
1. A bottle closure for a bottle where the bottle is of a type having a mouth to be closed, the bottle closure comprising: a body having an outer surround adapted to engage an outwardly extending integral collar of the neck of the bottle, which integral collar of the neck is spaced apart from an uppermost rim of the bottle, a seal adapted to be held under compression by the body against an uppermost rim of the bottle mouth, and a portion of the body adapted to be located within the mouth of the bottle and, at least during extraction, to effect a seal with an inner surface of the mouth of the bottle, the interlocking fit being effected by an inwardly directed lip adapted to engage a lower edge of the integral collar of the bottle, wherein the inwardly directed lip continuously surrounds the body of the closure, the seal being comprised of at least in part a material providing substantial resistance to the passage of oxygen there through, wherein the seal is of a form and positioned as a part of the closure such that it will extend substantially across the mouth of the bottle and the uppermost rim of the bottle mouth when the closure is in a closure position in respect of a bottle so as to provide thereby at least substantial resistance of gas passage there past or there through to prevent permeability of gas passage through the body of the closure, and wherein the inwardly directed lip is provided by a detachable tear away strip and is attached to a remainder of the body such that the lip can be manually separated from the remainder of the body and from the bottle whereby to reduce the interlocking effect to allow for subsequent removal of the closure from a closure position in relation to the bottle, and wherein the detachable tear away strip is attached to the remainder of the body of the closure by a weakened portion that substantially surrounds the body of the closure and includes a first location that intersects the inwardly directed lip with a large radius so that, when the closure is placed in position on the bottle, the inwardly directed lip can be forced to ride over and engage the lower edge of the integral collar of the bottle to retain the seal under compression and so that the detachable tear away strip is sufficiently tearable, while the weakened portion extends over the outer surface of the integral collar of the bottle in an engaged configuration so as to be positioned below the uppermost rim of the bottle with a portion of the outer surround extending over the outer surface of the integral collar between the weakened portion and the seal with the inwardly directed lip extending inwardly beyond an innermost portion of the weakened portion.
