Abstract

A system for dispensing carbonated beverage and ice into an open container uses a bottom filling technique in which the outlet port of the nozzle is proximate to a bottom of the open container in order to dispense the carbonated beverage. Preferably, the carbonated beverage is maintained in a pressurized state within the nozzle until immediately prior to opening the valve in order to maintain appropriate carbonation of the beverage. It is preferred that ice be added after the nozzle is located proximate the bottom of the open container. The ice dispenser includes a funnel located concentrically around the nozzle in order to supply ice around the nozzle into the open container. In order to avoid excessive foaming, it is important that the temperature of the carbonated beverage be chilled to approximately the surface temperature of the ice being added into the open container.

Claims

1. A system for dispensing carbonated beverage into an open container comprising:

a source of carbonated beverage;

a downwardly extending nozzle which is adapted to dispense carbonated beverage into an open container such that an outlet port for the nozzle is in close proximity to a bottom of the open container when dispensing of the carbonated beverage is initiated;

a valve that controls the flow of carbonated beverage dispensing from the nozzle into the open container;

a valve actuator that positions the valve with respect to the outlet port of the nozzle;

an ice dispensing system which dispenses ice into the open container when the nozzle is located such that the outlet port of the nozzle is in close proximity with the bottom of the open container;

an activation sensor that outputs an activation signal; and

an electronic controller that receives an activation signal and outputs a signal to control the valve actuator in order to initiate dispensing of the carbonated beverage from the nozzle into the open container.

2. A system as recited in claim 1 wherein the ice dispenser comprises a funnel having an outlet through which the downwardly extending carbonated beverage nozzle extends such that the ice is supplied circumferentially around the nozzle into the open container.

3. A system as recited in claim 1 further comprising a chiller for chilling the carbonated beverage flowing from the source of carbonated beverage to the nozzle.

4. A system as recited in claim 3 wherein the chiller chills the carbonated beverage so that carbonated beverage dispensing from the nozzle into the open container is chilled to approximately a surface temperature of the ice.

5. A system as recited in claim 1 in which the open container is at least partially filled with ice before dispensing of the carbonated beverage into the open container is initiated.
