A portable carbonator includes a built-in CO2 supply system which operates on disposable gas generating cartridges. The system requires no electrical power and is self-sufficient and automatic. CO2 gas is generated by a chemical reaction between reagents which carbonates and/or propels the water. Whenever carbonated water is drawn, the reagents react and generate more CO2 so as to maintain a constant pressure of the carbonated water.

An article of manufacture comprising: a) carbonator means including a water reservoir for containing a predetermined quantity of water to be carbonated by the mixing of CO2 gas therein; b) gas generating means including reagents for generating CO2 gas within a gas generating chamber when the reagents chemically react, said gas generating chamber being in fluid communication with the water reservoir in said carbonator means, said reagents including, a fixed quantity of chemicals, said fixed quantity being selected to correspond to an amount necessary to generate enough CO2 gas to carbonate all of said predetermined quantity of water in said water reservoir to a predetermined level, and a separate charge of chemicals which periodically mix to generate CO2 gas for propelling carbonated water from said carbonator means; c) a pressure regulating chamber in fluid communication with both a gaseous head space in said water reservoir and said gas generating chamber, said pressure regulating chamber including a head space formed therein; d) valve means for accommodating the flow of carbonated water from said carbonator means when in an open state and preventing the flow therefrom when in a clsoed state; and e) control means responsive to the relative internal pressures between the gaseous head space in said water reservoir, the gas generating chamber and the pressure regulating chamber, for initiating or precluding the mixing of said separate charge of chemicals to initiate or stop the generation of the CO2 gas for propelling carbonated water from said carbonator means to thereby maintain the pressure of propelled carbonated water substantially constant.
