Abstract

A beverage dispenser (10) includes a concentrate container (30) coupled to a connector (46). The connector (46) couples gas to the concentrate container (30), and couples concentrate from the container (30) to a dispensing valve (44). A combined carbonation and refrigeration unit (38) produces cold soda and provides cooling for concentrate lines (52, 54, and 56) and for water line (50).

Claims

1. A beverage dispenser, comprising:

a concentrate container containing concentrate;

a connector coupled to the concentrate container, the connector comprising a gas pin and a concentrate pin, the pins penetrating the container, each pin comprising an opening and a fluid flow path through the pin, such that a gas flow path is provided into the container through the gas pin and a concentrate flow path is provided from the container to the connector;

a gas source coupled to the gas pin through the connector, the gas source supplying gas at a gas pressure; and

a concentrate dispensing valve coupled to the concentrate pin through the connector, such that, upon activation of the concentrate dispensing valve, concentrate flows from the concentrate container through the concentrate pin and the concentrate dispensing valve due to the gas pressure.

2. The beverage dispenser of claim 1, wherein the concentrate container is a 2-litre PET package.

3. The beverage dispenser of claim 1, wherein the connector comprises a piston coupled to a rotatable upper housing, and the pins are coupled to the piston, and wherein rotation of the upper housing causes the piston to move toward or away from the concentrate container.

4. The beverage dispenser of claim 3, wherein rotation of the upper housing in one direction moves the piston away from the concentrate container such that the pins are withdrawn from the container, and rotation in the other direction moves the piston toward the concentrate container such that the pins penetrate the concentrate container.

5. The beverage dispenser of claim 1, wherein the connector comprises a normally closed gas valve coupled to the gas pin, and a normally closed concentrate valve coupled to the concentrate pin.

6. The beverage dispenser of claim 5, further comprising a receiving receptacle for receiving the connector, wherein the normally closed gas and concentrate valves open when the connector is coupled to the receptacle.

7. The beverage dispenser of claim 1, and further comprising a controller, and an RFID tag coupled to the concentrate container, the controller being able to read information from the RFID tag.

8. The beverage dispenser of claim 7, wherein the information comprises data relating to the expiration date of the concentrate in the concentrate container, and the kind of concentrate in the container.

9. The beverage dispenser of claim 7, wherein the information comprises data that authenticates the concentrate container as an authorized container for use with the dispenser.

10. The beverage dispenser of claim 9, wherein the controller disables use of unauthorized containers.

11. The beverage dispenser of claim 1, and further comprising a bonus flavor container for supplying bonus flavors.

12. The beverage dispenser of claim 1, and further comprising a carbonator tank for producing soda, the soda being coupled to a soda dispensing valve.

13. The beverage dispenser of claim 12, and further comprising an evaporator inside the carbonator tank, such that the carbonator tank and soda in the carbonator tank are chilled.

14. The beverage dispenser of claim 13, and further comprising a concentrate line wound around the carbonator tank, the concentrate line coupled to the concentrate pin and carrying concentrate from the concentrate container, such that the concentrate is cooled by heat transfer to the carbonator tank.

15. The beverage dispenser of claim 13, and further comprising a water line wound around the carbonator tank, the water line coupled to a source of water and carrying water, such that the water is cooled by heat transfer to the carbonator tank.

16. The beverage dispenser of claim 15, wherein the cooled water is communicated to the carbonator tank to produce soda.

17. The beverage dispenser of claim 1, and further comprising an enclosure enclosing a carbonator tank, an evaporator, cooling water, and a concentrate line, such that the evaporator creates an ice bank from the cooling water, thereby cooling the carbonator tank and the concentrate line.

18. The beverage dispenser of claim 17, and further comprising a water line within the enclosure.

19. The beverage dispenser of claim 17, and further comprising an agitator within the enclosure magnetically coupled to a motor outside the enclosure, the agitator circulating water around the ice bank.

20. The beverage dispenser of claim 17, and further comprising beverage lines outside the enclosure and a recirculation pump within the enclosure magnetically coupled to a motor outside the enclosure, the recirculation pump for pumping cool water from the enclosure to cool the beverage lines.
