Abstract:
A system for carbonating a liquid with carbon dioxide gas, comprising:a pressurized source of carbon dioxide gas; a user-operable three-way valve system having a first, a second, and a third orifice providing a first, a second and a third valve state, which in the first state connects the first orifice with the second orifice, in the second state connects the second orifice with the third orifice, and in the third state closes internal passage between all orifices, the valve system connected from the first orifice and a conduit to the pressurized source of carbon dioxide gas; and a closure assembly having an interface to a nozzle of a container for liquid and an orifice connected through a conduit to the second orifice of the three way valve system; characterized in that placing the three-way valve system in the first state admits carbon dioxide under pressure to the container, placing the three-way valve system in the second state connects the container for liquid to the third orifice of the three way valve system, allowing the container for liquid to de-pressurize, and placing the three-way valve system in the third state closes all passages between orifices.
