US Patent 8636176 Liquid dispenser pinch valve

A two-piece pinch valve is disclosed. A first piece or part of the valve is fixedly installed into a dispensing cabinet. A second piece or part having a movable pinch bar that pinches and un-pinches a tube is installable into and removable from the first piece by hand. Removal of the second piece from the first pieces allows a tube to be directly installed into the pinch valve. Installation of the second piece into the first piece configures the valve for operation. The second piece is installed into slots in the first piece. The slots and engaging protuberances on the second piece enable the second piece to be locked in place.
