Storage and Dispensing System for Potable Liquids

Abstract

A storage and dispensing system for potable liquids, e.g., wine, includes an inclined rack which holds a bottle with the neck down, a dispensing head sealing the bottle neck, and an inert gas supply system in fluid communication with the head. As liquid is dispensed from the bottle, low-pressure gas is admitted into the bottle, to inhibit oxidation of the wine. The system includes one or more self-sealing elements in the head itself and/or in gas lines between the head and a gas regulator. Because the self-sealing elements prevent air from entering into the system when the gas lines are detached, each bottle can have a dedicated head and bottles can be swapped out for dispensing, without the need for replacing bottle heads, sparging, or using more than one source of gas.

3. A wave washer according to claim 2, wherein there are equal numbers of upward and downward undulations.

4. A wave washer according to claim 1, wherein the undulations are configured and arranged so that when two such wave washers are positioned one atop the other, the wave washers' respective undulations nest.

5. A bottle head comprising: a valve having a valve stem, a fluid passage, and a dispensing port in fluid communication with the fluid passage;a seal portion extending from said valve, the fluid passage passing through the seal portion;at least one seal positioned around the seal portion;a movable element on the seal portion and adjacent to the at the least one seal; andat least one wave washer in accordance with claim 1 positioned on said seal portion between said movable element and said valve.

6. A bottle head according to claim 5, wherein the at least one wave washer comprises two wave washers positioned adjacent to each other on said seal portion between said movable element and said valve.

7. A bottle head according to claim 5, further comprising: a gas passage extending through the seal portion and separate from the fluid passage, the gas passage including a gas inlet port.

8. A bottle head according to claim 7, further comprising a self-sealing element in said gas passage.

9. A system useful for storing and dispensing a potable liquid from a bottle having a neck, the system comprising: a cabinet having an inclined surface and at least one opening configured and arranged to receive the neck of a bottle;a gas source of inert, non-oxygen containing gas;a pressure regulator in fluid communication with said gas source;a gas line in fluid communication with the pressure regulator;at least one bottle head configured and arranged to form a fluid seal when positioned in the neck of the bottle, the at least one bottle head including a gas passage and a fluid passage;wherein the gas line is in fluid communication with the gas passage of the at least one bottle head.

10. A system according to claim 9, further comprising: a bottle of wine in said cabinet and resting on the inclined surface, the bottle having a neck received in the at least one opening, the at least one bottle head positioned partially in and sealing the bottle neck.

11. A system according to claim 9, further comprising: a self sealing element in the gas line, in the bottle head gas passage, or in both.

12. A system according to claim 9, further comprising: at least one gas port positioned on said cabinet;at least one bottle head gas line fluidly communicating the gas passage of each at least one head with the at least one gas port;wherein the gas line fluidly connects between the pressure regulator and the at least one gas port.

13. A system according to claim 12, further comprising: at least one self sealing element in the at least one gas port, in the gas passage of the at least one bottle head, or in both.

14. A system according to claim 12, wherein: the at least one gas port comprises a plurality of gas ports, the gas line fluidly connected between the pressure regulator and the plurality of gas ports; andthe at least one opening comprises a plurality of openings configured and arranged to each receive the neck of a bottle.

15. A system according to claim 9, further comprising: a gas vent in fluid communication with the gas line.

16. A system according to claim 9, wherein the cabinet further comprises a lower section configured and arranged to contain a plurality of wine bottles.

17. A system according to claim 9, wherein the at least one bottle head further comprises: a valve having a valve stem and a dispensing port in fluid communication with the fluid passage;a seal portion extending from said valve, the fluid passage passing through the seal portion;at least one seal positioned around the seal portion;a movable element on the seal portion and adjacent to the at the least one seal; andat least one wave washer positioned on said seal portion between said movable element and said valve, the wave washer including a disk,an opening in the disk,a lever extending from the disk, andundulations formed in the disk.

18. A method of storing and dispensing wine, the method comprising: positioning a bottle head in the neck of a bottle containing the wine;resting the wine bottle on an incline with the bottle head down;fluidly connecting a source of inert, non-oxygen-containing gas with the interior of the bottle; anddispensing wine from the bottle.

19. A method according to claim 18, wherein the wine bottle is a first wine bottle and the bottle head is a first bottle head, and further comprising: providing a self sealing element in the first bottle head, or in a gas line fluidly connecting the first bottle head with the gas source, or in both;disconnecting the first bottle head from the gas source;fluidly connecting a second bottle having a neck, containing wine, and including a second bottle head positioned in the neck of the second bottle, to the gas source; andresting the second wine bottle on an incline with the second bottle head down.
