Patent ID: 7584872

Claim:
A fluid dispensing device comprising: a bottle for receiving fluid therein, a discharge tube, a pressurizing device coupled between said bottle and said discharge tube for pressurizing the fluid and for forcing the fluid to flow through said discharge tube without gravity, and said pressurizing device including a container coupled between said bottle and said discharge tube and having an inclined inner peripheral surface, a piston slidably received in said container and having an outer peripheral portion for engaging with said inner peripheral surface of said container, and said outer peripheral portion of said piston being engageable with said inner peripheral surface of said container in order to force the fluid into said discharge tube when said piston is moved toward said discharge tube, and said outer peripheral portion of said piston being disengaged from said inner peripheral surface of said container and to allow the fluid to flow through a gap between said inner peripheral surface of said container and said outer peripheral portion of said piston when said piston is moved away from said discharge tube, and a motor coupled to said piston to move said piston in a reciprocating action within said container.
