ABSTRACT:
The present invention is a metered liquid dispenser. A liquid dispenser has a liquid volume metering element located on a base attached to the top of the neck of a liquid dispenser. Using a lift fill mechanism, the metering element is vertically slid relative to the base to dispense a measured liquid volume. One-way valves located in the base and the top of the metering element alternately act to displace air from the element, and then provide suction to draw a measured liquid volume from the liquid dispenser through a dip tube into the element. The liquid is dispensed by inverting the metered liquid dispenser. The metering element has liquid level markings to indicate the liquid volume being entered to the element for dispensing, and is preferable partly transparent to visually display the liquid in the metering element.
