Low-cost post-mix beverage dispenser and syrup supply system therefor

Claim 2

In a post-mix beverage dispsenser system including a predetermined number of cabinet-mounted valve assemblies and associated dispensing nozzles rigidly affixed to a dispenser cabinet, each of said valve assemblies including a soda valve for controlling the flow of carbonated water to said nozzle, the improvement comprising: (a) a plurality of syrup valve adaptor assemblies of a number in excess of the predetermined number of cabinet-mounted valve assemblies, each said syrup valve adaptor assembly including, 1. a main housing having an open end removably connectable to a discharge spout of a gravity-flow syrup container, 2.

Claim 3

a normally-closed syrup valve in the main housing for controlling the flow of syrup from said spout, 3. a syrup outlet conduit connected to said syrup valve, and 4. a flow-rate control orifice plate in said outlet conduit in fluid communication with said syrup valve having a predetermined orifice size compatible with the brix value of a predetermined flavor of syrup, the orifice size of each valve adaptor assembly being different to be compatible with different brix values of syrup; and (b) a socket in each said cabinet-mounted valve assembly for removably receiving a selected one of said syrup valve adaptor assemblies to operatively position the syrup outlet conduit with respect to an

Claim 4

a normally-closed syrup valve in the main housing for controlling the flow of syrup from said spout, 3. a syrup outlet conduit connected to said syrup valve, and 4. a flow-rate control orifice plate in said outlet conduit in fluid communication with said syrup valve having a predetermined orifice size compatible with the brix value of a predetermined flavor of syrup, the orifice size of each valve adaptor assembly being different to be compatible with different brix values of syrup; and (b) a socket in each said cabinet-mounted valve assembly for removably receiving a selected one of said syrup valve adaptor assemblies to operatively position the syrup outlet conduit with respect to an

Claim 5

associated dispensing nozzle. 2. A post-mix beverage dispenser comprising: (a) a source of carbonated water; (b) a gravity-flow syrup container having a discharge spout with a normally-closed syrup valve therein, said syrup valve having an actuating means for opening and closing said valve extending from said spout; (c) a valve assembly including a mixing nozzle with a top opening for receiving carbonated water from said source and syrup from said container and a bottom opening for dispensing a carbonated post-mix beverage, a socket disposed adjacent to said nozzle in a vertical plane therewith, said socket having a top opening for receiving and supporting the discharge spout of the syrup container and a bottom opening through which the actuating means of the syrup valve extends in a vertical direction, a conduit connecting said syrup valve to the top opening of said nozzle, and a soda valve disposed above the top opening of said nozzle, said soda valve having an actuation means movable in a horizotal plane for opening and closing the soda valve; and (d) a valve actuation lever assembly including manually actuatable lever means having a pivot end mounted on a pivot shaft and an actuation end, and an intermediate lever operatively coupling said lever means to the actuation means of said syrup valve, said manually actuable lever means being directly coupled to the actuator means of said soda valve; whereby a manual force on said actuation end of said lever means actuates both said syrup and soda valves.

Claim 6

associated dispensing nozzle. 2. A post-mix beverage dispenser comprising: (a) a source of carbonated water; (b) a gravity-flow syrup container having a discharge spout with a normally-closed syrup valve therein, said syrup valve having an actuating means for opening and closing said valve extending from said spout; (c) a valve assembly including a mixing nozzle with a top opening for receiving carbonated water from said source and syrup from said container and a bottom opening for dispensing a carbonated post-mix beverage, a socket disposed adjacent to said nozzle in a vertical plane therewith, said socket having a top opening for receiving and supporting the discharge spout of the syrup container and a bottom opening through which the actuating means of the syrup valve extends in a vertical direction, a conduit connecting said syrup valve to the top opening of said nozzle, and a soda valve disposed above the top opening of said nozzle, said soda valve having an actuation means movable in a horizotal plane for opening and closing the soda valve; and (d) a valve actuation lever assembly including manually actuatable lever means having a pivot end mounted on a pivot shaft and an actuation end, and an intermediate lever operatively coupling said lever means to the actuation means of said syrup valve, said manually actuable lever means being directly coupled to the actuator means of said soda valve; whereby a manual force on said actuation end of said lever means actuates both said syrup and soda valves.

Claim 7

The dispenser of claim 2, further including a flow-rate contol orifice plate in said conduit in fluid communication with said syrup valve having a predetermined orifice size compatible with the brix value of a predetermined flavor of syrup.

Claim 8

The dispenser of claim 2, wherein said manually-actuable lever means includes a first lever for opening said soda vale and a second lever for opening said syrup valve, the direct coupling to the actuator means of said soda valve including a bifurcated protrusion defining a slot on the underside of said first lever for engaging the actuator means of the soda valve, the actuator means of the soda valve having an actuator pin which fits in said slot and a disc affixed to said pin which engages said bifuracted protrusion.

Claim 9

The dispenser of claim 2, wherein said manually-actuable lever means includes a first lever for opening said soda valve and a second lever for opening said syrup valve, said first and second levers having pivot ends mounted on a pivot shaft and manually engageable actuation ends, said actuation ends being disposed in substantially the same plane and forming a co-planar actuation surface, a portion of the actuation end of said first lever underlying a portion of the actuation end of the second lever in the direction of actuation; whereby said first lever may be actuated independently of said second lever to open said soda valve, but actuation of said second lever also actuates said first lever, causing both said syrup and soda valves to open.
