Abstract
Disclosed herein is a bottle stopper for automatically sealing the pouring spout of a bottle which in a preferred form includes a liquid within the bottle that is carbonated. The stopper is suitably formed of a single piece of material including a capsule which overlies the bottle neck and its associated toroidal lip of the bottle, a lever operatively connected to the capsule by means of a resilient tongue, in which the lever is biased to normally provide a stopper connected at a terminal extremity of the lever into sealing engagement with the top portion of the capsule.
Claims5
A closing device for sealing liquids in a bottle comprising, in combination;
- a capsule having an inner contour adapted to tightly engage the toroidal lip on the mouth of a bottle,
- a tongue hinged to an outer portion of said capsule formed integrally and of the same material as said capsule,
- a lever formed integrally to an extremity of said tongue remote from said capsule and of the same material on said capsule,
- said lever having an extremity above said capsule formed as a stopper, and a second extremity serving as a handgrip whereby when said handgrip is pressed towards an outer contour of said capsule, said stopper is removed from said capsule, biasing means fixedly interposed between said capsule and said lever on a side of said tongue opposite said stopper whereby releasing said handgrip inserts said stopper into said capsule,
- and sealing means on a surface of said stopper which extends into said capsule for sealing contents within the bottle.
