Abstract
A method and apparatus for storing and dispensing fluids such as syphon seltzer water under about 10 atmospheres of pressure. A plastic bottle is provided in which a valve mechanism is inserted within the neck of the bottle. A disposable cap covers the end of the bottle to prevent contamination of the valve during storage. When the contents of the bottle are to be dispensed, the cap is removed and discarded and a head member is attached to the outside wall of the neck of the bottle. The head contains a valve actuation mechanism which opens the valve and the liquid is dispensed through a nozzle in the head. The head may be removed when the contents of the bottle are dispensed or at any time before being fully dispensed. The bottle is discarded or recycled and the head member is detached and reattached to a full bottle of liquid, such as syphon seltzer water.
