ABSTRACT:
A method and apparatus for injecting CO.sub.2 gas into a bottled liquid to carbonate or maintain carbonation in the liquid. A valved coupling having a conduit extending there through is screwably attached to a P.E.T. bottle substantially filled with liquid. The valve is depressed .while the bottle is squeezed to remove any excess air in the bottle. Regulated CO.sub.2 gas is then fed through a connector that is attached to the coupling to carbonate the liquid. Once carbonated, the connector is removed while the coupling remains in place to maintain carbonation.
