The present invention is an attachment that can pressurize a beverage container with carbon dioxide or other suitable pressurized gaseous fluid. The attachment has a first threaded opening that can be screwed onto the container and a second opening which can be coupled to either a pressurized gas cartridge or a pressurized gas tank. Extending from the carbonator is a button that is coupled to a valve which controls the flow of gas into the container. The button and valve are coupled to a spring that functions as a regulator which controls the gas pressure within the container. When the button is depressed, the valve is opened and gas flows into the container until the gas pressure overcomes the spring force and closes the valve. Varying the displacement of the button varies the spring force and the gas pressure within the container. The user can thus vary and control the gas pressure of the container by manipulating the button.

[ What is claimed is:] [1.] An attachment assembly operable to pressurize a container and adapted to be coupled to a cartridge that contains a pressurized gaseous fluid or a tank that contains a gaseous fluid, comprising:a housing defining a first opening that is adapted to be coupled to the container and a second opening adapted to be coupled to the cartridge;a valve operatively connected to said second opening, said valve operable to move between a closed position and an open position, such that said valve allows gas to flow from said second opening to said first opening and into the container when in an open position;a button operable to move relative to said housing and is operatively connected to said valve to move said valve from said closed position to said open position;a variable regulator that can move said valve and said button from said open position to said closed position when gas pressure within the container reaches a first predetermined level, said variable regulator being constructed to allow a variation in the first predetermined pressure level by moving said buttons;a piercer coupled to said housing and adapted to pierce the cartridge; and,an adapter adapted to be coupled to said second opening and the tank, said adapter having a plunger engageable with said piercer so that gas flows from the tank to said valve when said adapter is coupled to said second opening.
