Abstract
A attachment that can be attached to the opening of a container to pressurize the same with a gas. The attachment has a housing which holds a removable cartridge that contains either pressurized nitrogen or CO.sub.2. Extending from the attachment is a button that is connected to a valve which controls the flow of gas into the container. The button and valve are coupled to a spring which functions as a regulator that controls the gas pressure within the container. When the button is depressed, the valve is opened and the gas is allowed to flow into the container. The spring maintains the valve in the open position until the gas pressure overcomes the spring force and closes the valve. Varying the movement of the button varies the spring force and the gas pressure within the container.
