A fluid dispensing device includes a pressurizing device (30) coupled between a fluid bottle (10) and a tube (20) for forcing the fluid to flow through the tube (20) without gravity, the pressurizing device (30) includes a container (31) having an inclined inner peripheral surface (38), and a piston (40) received in the container (31) and having an outer peripheral portion (41) for engaging with the inclined inner peripheral surface (38) of the container (31) in order to pump the fluid into the tube (20) with a coil (50) when the piston (40) is moved toward the tube (20), and for being disengaged from the inner peripheral surface (38) of the container (31) when the piston (40) is moved away from the tube (20).
