Gas generator attachment

A carbon dioxide gas generator device for removeable attachment to a liquid beverage container in communication with an inlet opening thereof, the device comprising:

• a first cup means for retaining a quantity of water;
• a second cup means for retaining a second substance which is chemically reactive with the water when combined therewith to generate carbon dioxide gas;
• means combining the water and chemically reactive substance in a common enclosed mixing location to induce a chemical reaction therebetween resulting in the generation of carbon dioxide gas;
• a gas outlet in communication with the mixing location and with the inlet opening of the beverage container;
• and
• means removeably attaching the gas generator device to the beverage container for receiving generated carbon dioxide gas at such a location on the container that the gas outlet of the device is in communication with the inlet opening of the container to permit carbon dioxide gas to flow from the gas generator device to the interior of the container to carbonate liquid beverage therein.

The combination of a container and a gas generator device for removeable attachment thereto in communication with an inlet opening of the container, to pressurize the container for dispensing a flowable substance therefrom, the device comprising:

• a first chamber for retaining a first mixable substance;
• a second chamber for retaining a second mixable substance which is chemically reactive with the first substance when combined therewith;
• means combining the first and second substances in a common enclosed mixing location to induce a chemical reaction between the substances resulting in the generation of gas;
• a gas outlet in communication with the mixing location for release of generated gas;
• and a
• container for holding a flowable substance said container having an inlet opening with a closure means located therein having an inlet passage for receiving generated gas and a dispensing valve for releasing the flowable substance from the container upon demand;
• and
• means removeably attaching the gas generator device to the container for receiving generated gas at such a location on the container that the gas outlet of the generator device is in communication with the inlet passage of the closure means to permit gas to flow from the gas generator device to the interior of the container;
• said gas generator device being detached from the container prior to activation of the dispensing valve.

An apparatus for rapidly carbonating a liquid beverage comprising:

• a pressure vessel forming a carbonation chamber on the interior thereof;
• a removeable container assembly adapted to be positioned in a fixed position relative to the pressure vessel, the container assembly when assembled, being capable of forming a gas generation chamber, the container assembly including a chemical container for containing a quantity of carbon dioxide generating compound, and a water container above the chemical container for retaining a quantity of water, the water container having a bottom opening in communication with the chemical container;
• a moveable bottom closure member sealingly closing the bottom opening of the water container to retain water therein;
• a first retaining means to hold the container assembly at a fixed location relative to the pressure vessel;
• a second retaining means to retain the container assembly in an assembled position to form a gas generation chamber capable of containing and releasing pressure generated therein during the generation of carbon dioxide gas;
• actuation means to cause opening of the bottom closure member to release water from the water container into the gas generation chamber;
• connecting means extending between the carbon dioxide generating chamber and the carbonation chamber to permit carbon dioxide gas to flow from the generation chamber to the carbonation chamber;
• means to release pressure from the carbonation chamber;
• and
• outlet means to remove liquid from the carbonation chamber.
