1. A container assembly comprising:
a container having a chamber for holding a liquid; and
a gas dispensing assembly for providing pressurized carbon dioxide gas to the chamber to carbonate the liquid in the chamber, the gas dispensing assembly including:
an onboard gas source having a gas tank attached to the chamber and configured to hold the carbon dioxide gas under pressure;
a gas supply conduit including a gas outlet fluidly coupled to deliver the pressurized carbon dioxide gas from the gas tank into the chamber and a gas supply valve fluidly coupled between the gas tank and the gas outlet, the gas supply valve configured to control a flow of the pressurized carbon dioxide gas from the gas tank to the gas outlet so as to output the pressurized carbon dioxide gas into the chamber; and
a gas inlet fluidly coupled to the gas tank and configured to receive pressurized carbon dioxide gas to refill the gas tank while the gas tank is attached to the chamber, the gas inlet configured to refill the gas tank by receiving and delivering only the pressurized carbon dioxide gas to the gas tank and without delivery of liquid or carbon dioxide source material,
wherein the chamber holding the liquid and the attached gas dispensing assembly including the gas tank are portable and manipulable by hand by a user to drink the liquid from the chamber.
