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. A probe may be attached to the cup-shaped body for penetrating a cap and removably holding a plug from the cap during dispensing with the plug being automatically replaced in the cap upon withdrawal of the probe. Alternatively, the cup-shaped body may be provided with a threaded compression nut having inwardly and axially directed fingers thereon for engaging a lip of the bottle to hold the vented liquid dispenser on the mouth of the bottle.
