Abstract: A beverage carbonator constructed as a pitcher shaped pressure vessel which functions as a carbonation chamber and which has a water canister and a gas generation chamber removably positioned inside the carbonation chamber. Carbon dioxide is produced by releasing internally stored water from the water canister into a carbon dioxide generating chemical in the gas generation chamber and then the carbon dioxide passes into the carbonation chamber where it is dissolved into a liquid beverage.

Abstract: A beverage carbonator having a pitcher shaped carbonation vessel which is detachably pneumatically connected to a reaction vessel in which carbon dioxide is produced by releasing internally stored water into a carbon dioxide generating chemical and passing the carbon dioxide into the carbonation vessel where it is dissolved into a liquid beverage. The carbonation vessel can be reconnected to the reaction vessel to recarbonate the unused portion of the beverage after it loses carbonation over a period of time and then disconnected for pouring the remainder of the beverage from the carbonation vessel.

Abstract: A process and apparatus for rapidly carbonating water for use in applications such as beverage mixes by producing carbon dioxide gas by chemical reaction within a first pressure vessel, transferring the carbon dioxide to a second pressure vessel where it is injected under pressure beneath the water in the second pressure vessel to carbonate the water therein while maintaining sufficient pressure to prevent dissolved carbon dioxide from coming out of solution in the water and for dispensing the carbonated water upon demand. Restrictive venting of the second pressure vessel may be used if needed, to aid in the transfer of carbon dioxide from the first to the second pressure vessel.
