Abstract

Devices and methods for extraction of a beverage from a beverage bottle, such as a wine bottle, using an extraction device. An aeration nozzle may be used to generate one or more jets of beverage arranged to expose the beverage to ambient air or other surrounding gas.

First claim

The invention claimed is:

1. A beverage dispensing device for dispensing wine, comprising:
a conduit arranged to provide a flow of wine under pressure to a distal end of the conduit;
a housing having an inlet fluidly coupled to the distal end of the conduit and a flowpath extending from the inlet;
an outer ring attached to the housing and having a first inner surface defining an opening;
an inner ring having a second outer surface received in the opening and engaged with the first inner surface and a second inner surface that defines a second opening;
a plug having a third outer surface received into the second opening; and
a plurality of flow channels each defined between the first inner surface and the second outer surface and by a groove on the first inner surface or the second outer surface, each flow channel having an inlet end fluidly coupled to the flowpath and extending to an outlet end, each of the plurality of flow channels being closed from the inlet end to the outlet end and configured to receive pressurized wine from the flowpath at the inlet end and to produce a jet of wine at the outlet end to travel from the outlet end through ambient air toward a user's cup;
wherein the second inner surface or the third outer surface includes one or more grooves to each define a flow channel between the second inner surface and the third outer surface.

2. The device of claim 1 , further comprising a source of pressurized gas arranged to deliver pressurized gas into a beverage container, wherein the conduit is fluidly coupled to the beverage container to receive the flow of wine under pressure caused by the pressurized gas in the beverage container.

3. The device of claim 2 , further comprising a valve arranged to control a flow of pressurized gas into the beverage container or to control the flow of wine under pressure from the beverage container.

4. A beverage dispensing device for dispensing wine, comprising:
a conduit arranged to provide a flow of wine under pressure to a distal end of the conduit;
a housing having an inlet fluidly coupled to the distal end of the conduit and a flowpath extending from the inlet;
a ring attached to the housing and having an inner surface and an outer surface that each have a plurality of grooves formed along the inner surface and the outer surface to define a plurality of flow channels each having an inlet end fluidly coupled to the flowpath and extending to an outlet end, each of the plurality of flow channels being closed from the inlet end to the outlet end and configured to receive pressurized wine from the flowpath at the inlet end and to produce a jet of wine at the outlet end to travel from the outlet end through ambient air toward a user's cup, the inner surface defining an opening;
a plug received in the opening and secured to the housing;
a source of pressurized gas arranged to deliver pressurized gas into a beverage container, wherein the conduit is fluidly coupled to the beverage container to receive the flow of wine under pressure caused by the pressurized gas in the beverage container;
a valve arranged to control a flow of pressurized gas into the beverage container or to control the flow of wine under pressure from the beverage container; and
a needle arranged to be inserted into a beverage container to deliver the pressurized gas into the beverage container and to deliver wine under pressure from the beverage container to the conduit.

5. The device of claim 1 , wherein the flowpath includes a portion with an increasing cross-sectional area in a direction from the inlet to the plurality of flow channels.

6. The device of claim 1 , wherein the second outer surface and the second inner surface each include a plurality of grooves that extend from an inlet side of the inner ring to an outlet side of the inner ring to form the plurality of flow channels.

7. The device of claim 6 , wherein the second outer surface and the second inner surface each have a conical shape.

8. The device of claim 1 , further comprising a nut positioned at an upper side of the outer ring, wherein the plug is arranged to engage with the nut to secure the inner ring and the plug to the outer ring.

9. The device of claim 1 , wherein the outer ring or the inner ring includes one or more tabs arranged to selectively block and unblock a flow channel.

10. The device of claim 1 , wherein the housing includes an inlet opening to define the inlet, and a seal arranged in the inlet opening to sealingly engage with an outer surface of the conduit.

11. The device of claim 1 , wherein the plurality of flow channels are arranged to produce a plurality of jets of wine that are parallel to each other.

12. The device of claim 1 , wherein the outlet ends of the plurality of flow channels are arranged in at least two concentric circles.

13. The device of claim 1 , wherein the plurality of flow channels are arranged such that jets of wine intersect at a location positioned away from the outlet ends of the plurality of flow channels.

14. The device of claim 1 , wherein the plurality of flow channels are arranged to produce a plurality of jets of wine, wherein at least a portion of the jets diverge from one another.

15. The device of claim 1 , wherein each of the plurality of flow channels has a cross-sectional area that is less than a smallest cross-sectional area of the flowpath, and a total cross-sectional area of all of the plurality of flow channels is equal to or greater than the smallest cross-sectional area of the flow path.

16. The device of claim 1 , wherein each of the plurality of flow channels has a cross-sectional area that is less than a smallest cross-sectional area of the flowpath, and a total cross-sectional area of all of the plurality of flow channels is less than the smallest cross-sectional area of the flow path.

17. The device of claim 1 , the plurality of flow channels includes at least six flow channels, and each of the plurality of flow channels has a diameter of 0.25 mm to 0.75 mm.

18. The device of claim 17 , wherein each of the plurality of flow channels has a length of 4 mm to 10 mm.

19. The device of claim 1 , wherein each of the plurality of flow channels has a length to diameter ratio of 40:1 to 16:3.

20. The device of claim 1 , wherein each of the plurality of flow channels is tapered so as to have a cross sectional area at the inlet end that is different from a cross sectional area at the outlet end.

21. The device of claim 1 , further comprising a selector attached to the housing and arranged to selectively close or open at least some of the plurality of flow channels.
