A coupler adaptor (32) is provided for use in operative association with a container (16) and a valve (26). The container houses relatively high pressurised carbon dioxide gas for use in carbonating a beverage. The valve is actuated in order to release the gas to an interface passage (52) formed in the coupler adaptor. The coupler adaptor has a pair of grooves (54, 56) formed on opposite sides of the interface passage for receiving O-rings (58, 60). The coupler adaptor is also in operative association with a pressure regulator (62). The pressurised gas enters the pressure regulator from the coupler adaptor interface passage. The coupler adaptor remains operatively joined to the pressure regulator without retaining structure due to the balanced gas pressure which results because of the O-rings positioned adjacent the coupler adaptor interface passage. |
