Closure means for providing a resealable closure for a bottle containing champagne, sparkling wines, or the like comprises a stopper for insertion into the neck of a bottle to close it; and retainer means secured to the neck of the bottle to be closed. The retainer means is pivotable between an open position in which the it does not engage the stopper and an operative position in which the retainer positively engages with the stopper so as to retain the stopper in the neck of the bottle. The stopper is preferably provided with engagement means such as a groove on at least one surface thereof external to the closed bottle. The retainer means in its operative position positively engages with the engagement means of the stopper so as resist movement of the retainer means relative to the stopper away from the operative position. The stopper, the retainer means or both are resilient so that it is necessary to deform the stopper, the retainer means or both in order to bring the retainer means into the operative position.
