ABSTRACT:
A bottle closure for sealingly closing a bottle while providing access to the interior of the bottle, the bottle being of the type having a neck with external threads thereon, and a mouth at the top of the neck. The bottle closure including a generally cylindric stopper having a radially outwardly projecting flange, a radially inwardly tapering lip projecting axially outwardly from one end of the stopper for insertion into the bottle through the mouth for sealing the bottle and at least one passageway extending through the stopper. The stopper has ears which are axially spaced from the flange.
