Abstract
A dispensing mechanism for a container of liquid has a chamber formed by a flexible wall which compresses and expands in response to movement of a discharge nozzle assembly. A first fluid passage communicates between the container and the chamber and a second fluid passage communicates between the chamber and the discharge nozzle outlet. Check valves are used to control flow of liquid from the container to the chamber and the chamber to the outlet so a predetermined amount of liquid is discharged.
