Abstract: A vented liquid dispenser with a gravity feed of liquid from an inverted bottle includes a cup-shaped body having a center tube extending through an opening in the bottom of the cup-shaped body. A hollow tubular valve member is slidably mounted on the tube and a washer is secured to the lower end of the valve member in sliding sealing engagement with the tube and movable into and out of engagement with a seat surrounding the opening in the cup-shaped body. A lifter extending axially through the valve body has a vent closure at one end engageable with the valve member to seal the valve member with the opposite end engaged by a pivoted handle on the cup-shaped body. A single spring is connected between the lifter, the valve member and the tube for controlling the closing of the vent closure and the closing of the opening in the cup-shaped body.

Abstract: A vented gravity dispenser for a liquid contained in a closed container. A clamp comprising a bevelled skirt, split compression ring and a nut are provided to sealingly attach said dispenser to said container. The present disclosure also details a dual acting valve, comprising a liquid discharge part and an air inlet part, which are co-operatively actuated.

Abstract: A dispensing system for bottled water, having a vented fluid dispenser assembly secured to the neck of a bottle which is inverted and supported by a bracket. The vent tube extends inward through the fluid to near the bottle bottom and ends with a check valve. A concentric valve member located within a flow tube seals against a valve seat and is manipulated by the reciprocating motion of a sleeve which surrounds the flow tube. The valve member is shaped with varying diameters, to regulate flow rate as a function of its elevation relative to the valve seat. The outer end of the valve member is releasably fastened to the sleeve center.
