Beverage extractor with container disengagement feature
View Patent ↗Devices and methods for extraction of a beverage from a beverage bottle, such as a wine bottle, using an extraction device. A clamp of the extraction device may include a container engagement surface arranged to disengage the clamp from the container neck when the clamp is pulled upwardly relative to the container neck. The container engagement surface may include a surface that slopes upwardly and outwardly relative to the container neck and that moves the clamp radially outwardly and away from the container neck as the clamp is moved vertically upwardly relative to the container neck.
1. A beverage dispensing device, comprising:
a body including a conduit arranged to receive a flow of beverage under pressure from a beverage container and to dispense the beverage at a dispensing outlet of the conduit; and
a clamp arranged to engage a container neck to secure the body relative to the container neck, the clamp including a container engagement surface that slopes outwardly and upwardly relative to the container neck and is arranged to disengage the clamp from the container neck as the clamp is pulled upwardly relative to the container neck.
2. The device of claim 1 , wherein the container engagement surface is arranged to contact a lip of a container and exert a radially outward force on the clamp to move the clamp away from the lip of the container as the clamp is moved upwardly relative to the container neck.
3. The device of claim 1 , wherein the container engagement surface is arranged to contact the container neck and exert a radially inward force on the container neck.
4. The device of claim 1 , wherein the clamp includes at least one arm arranged to engage with the container neck, and wherein the container engagement surface extends vertically on the at least one arm.
5. The device of claim 4 , wherein the clamp arm includes two arms that are opposed to each other and arranged to engage the container neck with the container neck positioned between the arms, each arm including a container engagement surface that extends vertically on the respective arm.
6. The device of claim 5 , further comprising a base, wherein the two arms are movably mounted to the base such that the arms can be moved towards and away from each other.
7. The device of claim 6 , wherein the base includes a stop arranged to contact a top of the container neck positioned between the arms, wherein the arms are pivotally mounted to the base on a proximal side of the arms and the container engagement surfaces are located on a distal side of the arms.
8. The device of claim 7 , wherein the arms are spring biased to move toward each other.
9. The device of claim 6 , wherein the body is mounted for slidable movement relative to the base.
10. The device of claim 9 , the body further including a needle extending downwardly from the body and arranged for insertion through a closure of the container.
11. The device of claim 9 , wherein upward force on the body moves the body upwardly relative to the base, and moves the base and arms upwardly relative to a container neck engaged by the arms.
12. The device of claim 1 , the body further including a needle extending vertically downwardly from the body and arranged for insertion through a closure of the container, wherein the container engagement surface is arranged to slope upwardly and outwardly relative to the needle.
13. The device of claim 12 , further comprising a base that includes the clamp, the body being movable vertically relative to the base.
14. The device of claim 13 , the base further including a needle guide arranged to contact a top of a container neck engaged by the clamp, wherein the needle guide is arranged to guide movement of the needle through the closure with downward movement of the body relative to the base.
15. The device of claim 13 , wherein the clamp includes at least one arm movable relative to the base and that includes the container engaging surface.
16. 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 beverage under pressure caused by the pressurized gas in the beverage container.
17. The device of claim 16 , further comprising a valve arranged to control a flow of pressurized gas into the beverage container or to control the flow of beverage under pressure from the beverage container.
18. The device of claim 17 , further comprising a needle arranged to be inserted through a closure of a beverage container to deliver the pressurized gas into the beverage container and to deliver beverage under pressure from the beverage container to the conduit.
