ABSTRACT:
Plural liquid containing bottles of differing sizes are simultaneously held in a cabinet in an inverted position so that the liquid flows by gravity from an orifice at the top of each bottle. A tension spring controls the vertical position of a first, fixed bearing surface for the top of each bottle relative to a second bearing surface for the bottom of the bottle to facilitate insertion of different sized bottles between the surfaces. A valve is selectively opened to enable liquid to be dispensed by gravity from the bottle through a dispensing tube extending through a stopper in the orifice. A vent tube attached to the stopper has an open end exposed to the atmosphere above a liquid-air interface in the bottle to assure the flow of liquid to the valve. The second surface carries the stopper and is on a plate that is detachable from the remainder of the holding structure and is horizontally slidable toward and away from a door through which bottles are inserted into the cabinet.
