ABSTRACT:
An apparatus for dispensing carbonated fluids or beverages which employs the vapor pressure of the beverage, i.e., the pressure of carbonation, as the sole propelling or dispensing force, is disclosed. The apparatus comprises a valve mechanism that includes a main valve body and an adapter for detachably coupling the valve mechanism to the fluid container or bottle. An elongated siphoning tube projects into the fluid container and in self-sealing engagement with the adapter means. The valve mechanism further comprises a valve stem movably mounted within a central cavity or channel formed in the main valve body, a fluid discharge spout in operable communication with the cavity or channel and a spring which serves to maintain the valve in a normal closed position. The fluid is discharged from the container by causing the valve stem to be moved into a downward and open position. The apparatus of the invention comprises a minimum of parts, may be easily manufactured and avoids the disadvantages of known dispensing apparatus. In accordance with a particularly advantageous embodiment of the invention, the adapter, used to secure the valve mechanism to the container, is designed such that it is readily adaptable for use with fluid containers or bottles of varying designs and shapes.
