Abstract
A fluid dispensing device includes a pressurizing device coupled between a fluid bottle and a discharge tube for forcing the fluid to flow through the discharge tube without gravity, the pressurizing device includes a container having an inclined inner peripheral surface, and a piston slidably received in the container and having an outer peripheral portion for selectively engaging with the inclined inner peripheral surface of the container in order to pump the fluid into the discharge tube when the piston is moved toward the discharge tube with a coil, and for being selectively disengaged from the inner peripheral surface of the container when the piston is moved away from the discharge tube.
