ABSTRACT:
A fluid dispensing device includes a bottle for receiving fluid, a discharge tube, and a pressurizing device coupled between the bottle and the discharge tube, for pressurizing the fluid and for forcing the fluid to flow through the discharge tube without gravity. The pressurizing device includes a container coupled between the bottle and the discharge tube, a piston slidably received in the container, and a moving device for moving the piston in a reciprocating action within the container. For example, a motor is coupled to the piston with a crank, to move the piston in the reciprocating action within the container.
