Abstract
A gas source for pressuring sparkling and other beverage containers, e.g., to re-pressurize the container to keep a carbonation level of beverage during storage. A gas cylinder can include a cap with a flange and catch below the flange. The catch can be engaged by a cylinder support to move the cylinder into contact with a piercing element to pierce the gas outlet of the cylinder and form a seal between the cylinder and gas receiver. A pressure indicator can have a single pressure sensor to indicate a capacity of a gas cylinder to deliver pressurized gas and a pressure in a beverage container.

A pressurized gas source for use in providing pressurized gas into a beverage container, the gas source comprising:
- a housing including a support for a gas cylinder holding the pressurized gas;
- a gas outlet mounted to the housing and arranged to provide the pressurized gas for delivery to the beverage container, the gas outlet including an outlet valve;
- a regulator supported by the housing and arranged to receive gas at a first pressure from the gas cylinder and to provide gas at a second pressure lower than the first pressure to the gas outlet;
- a conduit coupled between the regulator and the gas outlet to deliver the gas from the regulator to the gas outlet;
- and
- a pressure indicator configured to indicate whether a pressure in the beverage container is over a threshold when the gas outlet is coupled to the beverage container and the outlet valve is open, and to indicate whether the gas cylinder has capacity to pressurize a beverage container when the outlet valve is closed.
