Abstract

A beverage dispensing system includes a base to which a dispensing head is removably attached without additional fasteners. Beverage-forming liquids are supplied through a plurality of separate conduits in the base. Each base conduit has a normally closed valve that normally blocks fluid flow. The dispensing head has at least one passageway that receives liquid from an associated one of the base conduits. A projection associated with each dispensing head passageway opens the associated conduit valve to allow fluid flow from the base to the head. Dispensing valves in the dispensing head regulate the dispensing of the beverage. By selectively opening the dispensing valves, a plurality of beverages are formed from combinations of one or more liquids. A dispensing head includes an inlet opening and an outlet opening at each end of a passage extending through a body, the inlet opening having a smaller cross-sectional area than the outlet opening.

Claims

1. A nozzle comprising:

a first discharge passage with a non-linear flow path, the first discharge passage having an inlet and an outlet, the first discharge passage further shaped to have a cross-sectional area that increases from the inlet opening to the outlet opening; and

a second discharge passage at least partially surrounded by the first discharge passage, the second discharge passage having an inlet opening for receiving a fluid stream and an outlet opening through which the fluid stream is discharged.

2. The nozzle according to claim 1, further comprising at least two second discharge passages, each of the at least two second discharge passages having an inlet opening for receiving the fluid stream and an outlet opening through which the fluid stream is discharged.

3. The nozzle according to claim 1, further comprising at least two first discharge passages.

4. The nozzle according to claim 1, wherein the second discharge passage extends at least in part in a linear path and the first discharge passage extends at least partially in a curve around the second discharge passage.

5. The nozzle according to claim 4, wherein the second discharge passage further includes a diverting channel at a discharge outlet that extends in a direction lateral to the linear flow path direction so that fluid discharged from the first and second discharge passages is directed in different directions as they are discharged from the nozzle.

6. A nozzle comprising:

a first discharge passage through which a first fluid stream is discharged;

a second discharge passage that at least partially surrounds the first discharge passage, the second discharge passage having an inlet opening and an outlet opening through which a second fluid stream is discharged and further shaped to have a cross-sectional area that increases from the inlet opening to the outlet opening; and

a third discharge passage that at least partially surrounds the first discharge passage.

7. The nozzle of claim 6, wherein the third discharge passage has an inlet opening spaced from the second discharge passage inlet opening for receiving a third fluid stream and an outlet opening spaced from the second discharge passage outlet opening through which the third fluid stream is discharged and wherein the third discharge passage is shaped to have a cross-sectional area that increases from the inlet opening to the outlet opening.

8. The nozzle of claim 6, further comprising a first head with a body that defines the first discharge passage, and a second, ring-shaped head that defines the second and third discharge passages wherein the second ring-shaped head is seated around the first head.

9. The nozzle of claim 6, further comprising a fourth discharge passage that at least partially surrounds the first discharge passage and the third passage, the fourth discharge passage having an inlet opening spaced from the second discharge passage inlet opening and an outlet opening spaced from the second discharge passage outlet opening and that is further shaped to have a cross-sectional area that increases from the inlet opening to the outlet opening.

10. The nozzle of claim 6, wherein the first discharge passageway extends in a linear path through the nozzle and the second discharge passage at least partially curves around the first discharge passage.

11. A nozzle comprising:

a first dispensing head having a first discharge passage;

a second dispensing head having a second discharge passage at least partially surrounding the first discharge passage; and

wherein the second discharge passage has an inlet opening for receiving a fluid stream and an outlet opening through which the fluid stream is discharged;

wherein the second discharge passage is shaped to have a helical increasing cross-sectional area that increases along a length of the first discharge passage extending from the inlet opening to the outlet opening, and the second discharge passage forming a helix around the first dispensing head.

12. The nozzle of claim 11, wherein the second dispensing head includes at least two second discharge passages, each of the second discharge passages having an inlet opening and an outlet opening, both of the second discharge passages having a cross-sectional area that increases from the inlet opening to the outlet opening.

13. The nozzle of claim 12, wherein the first dispensing head includes at least two first discharge passages.

14. The nozzle of claim 11, wherein the first discharge passage extends at least in part in a linear path and the second discharge passage extends at least partially in a curve around the first discharge passage.

15. The nozzle of claim 14, wherein the first discharge passage further includes a diverting channel at the discharge outlet that extends in a direction lateral to the linear flow path direction so that fluid discharged from the first and second discharge passages is directed in different directions as they are discharged from the nozzle.

16. The nozzle of claim 11, wherein the first discharge passage extends along a first path and the second discharge passage extends along a second path that intersects with the first path.

17. The nozzle of claim 11, where the first dispensing head is shaped as a cylinder and the second dispensing head is shaped as a ring that surrounds the first dispensing head.

18. The nozzle of claim 11, further comprising a selectively releasable locking mechanism.
