Abstract
Abstract A liquor supply is disclosed for an automated liquor dispensing system. The liquor supply comprises a plurality of liquor storage bottles that are interconnected such that their interiors are connected in series. The first bottle of the series is connected to a positive displacement pump and the last bottle of the series has the surface of the liquor therein exposed to the atmospheric pressure. As the liquor is withdrawn by the pump from the first bottle the atmospheric pressure in the last bottle forces liquor to be transferred from each bottle in the series toward the bottle next closer to the pump thus enabling all the liquor in the bottles to be made available for dispensing by the pump.

Claim 1
Independent Claim
271 words
In a liquid storage system including a plurality of bottles intercoupled in an airtight series between an inlet that is open to atmosphere and an outlet coupled to a dispensing pump, a stopper assembly comprising: a stopper formed of hard material having a body with an elongated frusto-conical configuration, a circumferential flange on the relatively wide end of said body, inlet and outlet openings extending lengthwise through said body, a fitting for a suction tube on the relatively narrow end of said body and communicating with the inlet end of said outlet opening, and a pair of fittings at the wide end of said body and communicating with respective ones of said openings; and an adapter formed of relatively resilient material and having a frusto-conical sleeve configuration, said adapter being of such size as to fit over said stopper body with the wide end of said adapter engaging said flange; said body also having a lateral protusion at its relatively narrow end for retaining said adapter in place; whereby said stopper assembly can be fitted in airtight relationship into the mouth of any one of various sized bottles; wherein said stopper includes a disc-shaped member secured to the flanged end of said body, said pair of fittings being formed integrally with the outer surface of said member and each being radially spaced from the axial center of said member, the associated openings extending from their respective fittings through said disc-shaped member and then radially inward towards each other, the openings in said body being parallel to each other and aligned with the inner ends of the openings in said disc-shaped member.
