ABSTRACT:
A liquid dispenser for dispensing liquid from a container, includes an intake pipe to receive liquid from the container, an outlet to dispense liquid, a pressure supply mechanism to supply pressurized fluid to the container at a first pressure, and a dispensing mechanism. The dispensing mechanism is operable to dispense liquid from the container by reducing the pressure in the container to a second pressure, connecting the intake pipe to the outlet to dispense fluid from the container, and subsequently increasing the pressure in the container to the first pressure.
