Abstract:
1. An apparatus for dispensing a fluid, the fluid dispensing apparatus comprising: a housing defining an open interior; a resilient liner adapted to hold the fluid, the liner configured to be at least partially disposed in the interior of the housing; an applicator assembly for dispensing the fluid on the user's skin, the applicator assembly mounted on the housing, the applicator assembly including a pump assembly at least partially disposed in the housing, the pump assembly comprising wherein each movement of the actuator in the first direction reduces the volume of the variable volume chamber for generating positive pressure in the pump chamber and forcing fluid through the port in the piston member and to the applicator assembly for dispensing the fluid, and each movement of the piston member in the second direction increases the volume of the variable volume chamber and generates continuous negative pressure within the pump chamber for drawing fluid through the at least one opening in the end of the pump chamber and collapsing the liner.
