Abstract
A liquid dispenser includes a dispenser subassembly having an inlet, an outlet, and a pump in fluid communication with the inlet and the outlet, the pump being movable between a first position and a second position. The liquid dispenser also has a container including an opening for receiving a liquid and an actuating element connected thereto. The actuating element is engagable with the dispenser subassembly when the container and the dispenser subassembly are assembled together. Engagement of the actuating element with the dispenser subassembly is a prerequisite for operating the pump and dispensing the liquid from the dispenser. Also disclosed is a method of priming a liquid dispenser during final assembly thereof whereby the liquid dispenser will be immediately ready to discharge a liquid without further priming, such as is required with conventional liquid dispensers. The dispenser may also have a precompression system that stops liquid from being discharged until a predetermined pressure level has been attained in a pump chamber.
