Abstract

A system and method for dispensing sparkling and other pressurized beverages from a container. Sparkling wine and other beverages may be dispensed without removing a cork or other closure. One or more needles may be inserted through the closure and sparkling beverage dispensed through the one or more needles. The one or more needles may be inserted at an angle to the vertical or axis of the bottle opening in which the closure is positioned, e.g., to avoid contact with a metal retainer on the closure. Dispensed beverage may be directed to a pressurized reservoir to help maintain or recover carbonation prior to dispensing.

First claim

The invention claimed is:

1. A sparkling beverage dispensing system for use with a container holding a sparkling beverage under pressure above ambient and having a closure at an opening of the container, the system comprising:
at least one conduit arranged to penetrate through the closure such that a distal end of the at least one conduit is positioned inside the container to receive beverage from the container for dispensing;
at least one controllable valve fluidly coupled to the at least one conduit to control beverage flow out of the container via the at least one conduit to a dispensing outlet; and
a reservoir arranged to fluidly couple with the dispensing outlet and receive beverage dispensed from the dispensing outlet, the reservoir arranged to hold dispensed beverage under pressure and including a lid that is removable to allow beverage in the reservoir to be poured by hand from the reservoir;
wherein the at least one conduit, at least one controllable valve and reservoir are configured to permit flow of beverage from the container to the reservoir that is driven by pressure in the container.

2. The system of claim 1 , wherein the reservoir is arranged to vent to ambient pressure before or at a time of dispensing the beverage from the reservoir to a user's cup.

3. The system of claim 2 , wherein the reservoir includes a dispensing valve arranged to open to vent the reservoir and dispense the beverage in the reservoir.

4. The system of claim 1 , wherein the reservoir is arranged to vent pressure in the reservoir at a rate of no more than 5 psi/sec when in a closed state.

5. The system of claim 1 , wherein the lid includes a coupling arranged to engage with the dispensing outlet and receive beverage into the reservoir.

6. The system of claim 1 , wherein beverage enters the reservoir at a bottom of the reservoir.

7. The system of claim 1 , wherein the reservoir is fluidly coupled to the dispensing outlet and arranged to allow a pressure in the reservoir to equalize with a pressure in the container.

8. The system of claim 1 , wherein the at least one conduit includes a needle arranged to penetrate through the closure such that a distal end of the needle is positioned inside of the container, the needle being arranged to receive beverage from the container for dispensing.

9. The system of claim 8 , further comprising a needle guide arranged to engage the container and guide the needle in penetrating the closure, the needle guide arranged to guide the needle to enter the closure at an angle of 5 degrees to 70 degrees relative to a longitudinal axis of the container.

10. The system of claim 9 , wherein the needle guide is arranged to guide the needle along a linear path that is 20 to 40 degrees from the longitudinal axis.

11. The system of claim 1 , further comprising a source of pressurized gas, and the at least one valve includes a gas control valve to allow a flow of pressurized gas from the source of pressurized gas into the container via the at least one conduit.

12. The system of claim 11 , wherein the at least one valve includes a beverage dispensing valve to control flow of beverage from the at least one conduit to the dispensing outlet, and wherein the gas control valve permits flow of pressurized gas only when the beverage dispensing valve is closed.

13. The system of claim 1 , wherein the at least one valve includes a normally closed beverage dispensing valve that prevents flow of beverage from the at least one conduit to the dispensing outlet absent user action to open the normally closed valve.

14. A sparkling beverage dispensing system for use with a container holding a beverage under pressure above ambient and having a closure at an opening of the container, the system comprising:
at least one conduit arranged to penetrate through the closure such that a distal end of the at least one conduit is positioned inside the container to receive beverage from the container for dispensing;
at least one valve fluidly coupled to the at least one conduit to control beverage flow out of the container via the at least one conduit to a dispensing outlet;
a reservoir arranged to fluidly couple with the dispensing outlet and receive beverage dispensed from the dispensing outlet, the reservoir arranged to hold dispensed beverage under pressure; and
a source of pressurized gas arranged to provide first and second pressures which are different from each other, the source of pressurized gas arranged to provide the second pressure to the container, and to provide the first pressure to the reservoir, wherein the source of pressurized gas includes a regulator to provide the first and second pressures.

15. The system of claim 14 , further comprising
a first valve to control gas flow from the source of pressurized gas to the reservoir to provide the first pressure, and a second valve to control gas flow from the source of pressurized gas to the container to provide the second pressure to the container.

16. The system of claim 15 , wherein the second valve also controls beverage flow out of the container via the at least one conduit to a dispensing outlet.
