Beverage dispensing apparatus and retrofitting kit
First Claim
1. An apparatus for dispensing a potable beverage stored in a pressurized container, the apparatus comprising:
- tap means attachable to the container for providing a discharge flow path for the beverage stored therein, the tap means comprising a tap removably attachable to the beverage container;
valve means for opening and closing the discharge flow path, the valve means including a valve normally closing the discharge flow path;
a source of pressure including a gas cylinder containing an inert gas;
valve control means for operating the valve means, the valve control means utilizing said source of pressure to operate the valve means, the valve control means, when activated, moving the valve to open the path;
the valve control means including a second cylinder operable by the inert gas, a solenoid through which the gas is routed to the second cylinder, and controller means for activating the valve control means, the controller means including switch means for energizing and de-energizing the solenoid and sensing means for first sensing when a receptacle is positioned adjacent the tap means to activate the valve control means for beverage to be dispensed into the receptacle and for subsequently sensing when the receptacle has been withdrawn to deactivate the valve control means and stop dispensing of the beverage.

Abstract
Apparatus (10) for dispensing a potable beverage (B) stored in a container (K). A tap (16) is attached to the container and provides a discharge passage (18) for the beverage. A valve (20) opens and close the passage. A valve control unit (32) operates the valve. The container is a pressurized container and the valve control unit also utilizes this source (G) of pressure to operate the valve. A controller (60) activates the valve control unit. The controller includes a sensor (64) for first sensing when a receptacle is positioned adjacent the tap, to activate the valve control unit, for beverage to be dispensed into the receptacle. The controller subsequently senses when the receptacle has been withdrawn to deactivate the valve control unit and stop dispensing of the beverage. Dispensing is also automatically stopped if the receptacle is left in place for a preselected amount of time. The apparatus is available in a "kit" form for retrofitting existing dispensers. Further, two taps can be arranged in a side-by-side relationship for automatically dispensing beverage into two receptacles simultaneously.

11. An apparatus attachable to a standard potable beverage dispenser cabinet for the controlled dispensing of a beverage from a pressurized container the container being pressurized from an operatively associated source of inert gas, the apparatus comprising:
-
a tap, attachable to the pressurized container, including a discharge passage for the beverage contained in the container and a valve normally blocking the passage; valve control means for moving the valve to unlock the passage, the valve control means including an air cylinder to which pressurized gas from the operatively associated gas source is directed for moving the valve; a solenoid for operating the air cylinder; controller means for controlling operation of the valve, the controller means including sensing means for first sensing when a receptacle is positioned adjacent the tap to operate the valve control means and cause beverage to be dispensed into the receptacle and for subsequently sensing when the receptacle is withdrawn to further operate the valve control means to stop dispensing of the beverage; and mounting means for mounting said tap, said valve control means, said solenoid, and said controller means to the dispenser cabinet. - View Dependent Claims (12, 13, 14, 15)
