Abstract

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. The flange and ears retain a cap on the stopper but allow the cap to rotate with respect to the stopper so that the cap may be tightened on and loosened from the threads of the bottle without unsealing the stopper from the bottle.
