Abstract

A clamp of the dispensing device may include a container engagement surface arranged to engage and/or disengage the clamp from the container neck when the clamp is pushed downwardly or pulled upwardly relative to the container neck. The container engagement surface may include a surface with a lower portion that slopes upwardly and inwardly, and an upper portion 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 relative to the container neck. A latch may maintain a body portion of the dispensing device in an upper position, preventing needle insertion, until a container is suitably engaged with the base portion of the device, e.g., by a clamp. Sensors may detect engagement of a container with the device and/or insertion of a needle into the container.

First claim

The invention claimed is:

1. A method for dispensing beverage from a container, comprising:
engaging a container-mounted dispensing system with a container neck of the container by:
positioning a clamp attached to a base of the dispensing system over the container neck,
forcing the clamp downwardly onto the container neck such that the container neck moves at least one clamp arm of the clamp against a spring bias and enlarges a receiving space of the clamp, and
moving the container neck into the enlarged receiving space so as to be fully received into the receiving space; and

moving a body mounted to the base downwardly relative to the base to insert a needle mounted to the body through a closure of the container.

2. The method of claim 1 , wherein moving the container neck into the enlarged receiving space includes suspending the base and body on the container by an engagement force exerted by the at least one clamp arm on the container neck based on the spring bias.

3. The method of claim 1 , further comprising introducing pressurized gas into the container via the needle to pressurize an internal volume of the container.

4. The method of claim 3 , further comprising dispensing beverage from the container by forcing beverage to flow from the internal volume through the needle based on a pressure in the internal volume.

5. The method of claim 1 , wherein forcing the clamp downwardly includes engaging a lower portion of a container engagement surface on the clamp that slopes inwardly and upwardly relative to the receiving space with the container neck so the at least one clamp moves away from the container neck while the at least one clamp exerts an engagement force on the container neck.

6. The method of claim 5 , wherein the container engagement surface extends vertically on the at least one clamp arm.

7. The method of claim 5 , wherein the container engagement surface includes an upper portion positioned above the lower portion that slopes outwardly and upwardly relative to the receiving space, and wherein forcing the clamp downwardly includes engaging the container neck with the upper portion after engaging the container neck with the lower portion.

8. The method of claim 7 , wherein forcing the clamp downwardly includes exerting a radially outward force on the at least one clamp arm with the lower and upper portions of the container engagement surface as the clamp is moved downwardly relative to the container neck.

9. The method of claim 8 , further comprising forcing the clamp upwardly relative to the container neck to remove the container neck from the receiving space, the container engagement surface exerting a radially outward force on the at least one clamp arm as the clamp is moved upwardly relative to the container neck.

10. The method of claim 1 , wherein engaging the container-mounted dispensing system with the container neck includes engaging a stop arranged at an upper end of the receiving space to contact a lop of the container neck, the container neck being fully received in the receiving space when the top of the container neck contacts the stop.

11. The method of claim 1 , wherein engaging the container-mounted dispensing system with the container neck includes releasing a latch in response to the container neck being fully received in the receiving space, release of the latch enabling movement of the body downwardly relative to the base.

12. The method of claim 11 , wherein releasing the latch includes permitting the body to be moved from an upper position to a lower position relative to the base to insert the needle through the closure.

13. A beverage dispensing device, comprising:
a base to engage with a neck of a beverage container;
a body movably mounted to the base between upper and lower positions and having a needle attached to and extending from the body, the needle being arranged to be inserted through a closure of the beverage container to introduce pressurized gas into the beverage container and extract beverage from the container;
a first sensor arranged to detect that the container neck is engaged by the base; and
a second sensor arranged to detect that the needle is inserted through the closure of the beverage container.

14. The device of claim 13 , further comprising a controller arranged to enable gas flow if the first sensor detects engagement of the container with the base and the second sensor detects the needle inserted through the closure.

15. The device of claim 13 , wherein the base includes a clamp to engage with a neck of the container, and wherein the first sensor detects that the clamp has engaged with the container neck.

16. The device of claim 15 , wherein the first sensor includes a switch that is actuated by contact of a container neck engaged by the clamp.

17. The device of claim 13 , wherein the base includes a stop arranged to contact a top of a neck of the container when the container neck is engaged by the base, and wherein the first sensor includes a switch that is actuated by contact of the top of the container neck with the switch.

18. The device of claim 17 , wherein the stop includes a needle guide arranged to guide movement of the needle through the closure of the container.

19. A beverage dispensing device, comprising:
a base to engage with a neck of a beverage container;
a body movably mounted to the base between upper and lower positions and having a needle attached to and extending from the body, the needle being arranged to be inserted through a closure of the beverage container to introduce pressurized gas into the beverage container and extract beverage from the container;
a first sensor arranged to detect that the container neck is engaged by the base; and
a second sensor arranged to detect that the needle is inserted through the closure of the beverage container,
wherein the body is movable relative to the base between an upper position and a lower position, the second sensor includes a switch that is actuated when the body is in the lower position relative to the base, and the second sensor is arranged to detect that the needle is inserted through the closure of the beverage container when the first sensor detects that the base is engaged with a container neck and the second sensor switch is actuated to indicate the body is in the lower position.

20. The device of claim 13 , wherein the body includes a clamp to engage with the container neck, the first sensor is actuated by a container neck engaged by the clamp, and the second sensor detects the body is in a lower position relative to the clamp to indicate that the needle is inserted through the closure.

21. The device of claim 20 , wherein the first sensor includes a switch that is actuated by the container neck, and the second sensor includes a switch that is actuated by the body at the lower position relative to the clamp.

22. The device of claim 21 , further comprising a controller arranged to enable gas flow only if the first sensor switch is actuated by the container neck and the second sensor switch is actuated by the body at the lower position.

23. The device of claim 22 , wherein the controller includes a container orientation sensor arranged to detect an orientation of a container engaged by the clamp, the controller being arranged to deliver pressurized gas to the needle when the container orientation sensor detects the engaged container is oriented to pour beverage from the container.
