Drink supply canister for beverage dispensing apparatus
First Claim
1. A pressurizable drink supply canister for a beverage dispensing apparatus in a refrigerator, said pressurizable drink supply canister comprising:
- a body adapted to hold a variable volume of a syrup drink supply under pressure, the body having a plurality of ends, each of the ends defining at least a first and a second opening respectively;
a gas inlet valve mounted to a first one of the ends of the body, the gas inlet valve positioned at said first opening, the gas inlet valve having;
(a) an open position which enables pressurized gas to flow into the body to pressurize the syrup drink supply in the body;
(b) a closed position which blocks flow of the pressurized gas from the body through the gas inlet valve;
(c) a biasing member which predisposes the gas inlet valve to have the closed position; and
(d) at least one member which, when actuated, causes the gas inlet valve to have the open position thereby causing the pressurized gas to pressurize the syrup drink supply; and
a drink supply outlet valve coupled to said base having;
a spout with a longitudinally extending through opening defined by opposite ends, one of the opposite ends communicating with the body of the canister through the second opening in the body and the other one of the opposite ends of said spout through opening communicating with an external environment of the canister, the spout through opening being sized and shaped so as to at least partially house a sealing member engagable by the spout, the sealing member being displacable relative to the canister between open and closed positions to respectively enable pressurized syrup drink supply to flow from the canister through the second opening in the body and to block pressurized syrup drink supply to flow from the said second opening in the body.

Abstract
The present invention provides a drink supply canister for beverage dispensing apparatus for a residential refrigerator. The beverage dispensing apparatus includes a drink supplier including a drink supply canister holder for holding a plurality of the drink supply canisters, and a plurality of valve actuators for causing the drink supply to be selectively released from the drink supply canisters, a water supplier for selectively supplying carbonated water and non-carbonated water for producing the beverages, a gas supplier for supplying CO2 gas to carbonate the carbonated water provided by the water supplier and for supplying CO2 gas or other gas for pressurizing the drink supply canisters to provide a consistent flow rate of the drink supply from the drink supply canisters, and one or more beverage requesters for enabling users to request one of a plurality of beverages.
