ABSTRACT:
A closure cap for a bottle comprising a tubular housing adapted to seal the neck of the bottle includes a chamber having one end in communication with the interior of the bottle. A displaceable plug closes the other end of the tubular housing and includes an elongated stem having a valve formed on its lower end. Further insertion of the plug closes the valve against the tapered end wall at the open end of the housing so that sediment which has settled in the chamber when the bottle is inverted becomes trapped within the cap and remains separated from the contents of the bottle.
