Abstract
A multi reservoir dispenser includes a first reservoir for holding a first fluid and a second reservoir for holding a second fluid. The dispenser further includes first pump mechanism that includes a first displaceable plunger and a first plunger cavity that is disposed along a first flow path for receiving the first fluid and a second displaceable plunger and a second plunger cavity for receiving the second fluid. An actuator includes a selector and an actuator that are movable between: (a) a first position in which only the first plunger of the pump mechanism is actuated for discharging only the first fluid through a first orifice of a fluid dispensing manifold by causing the first fluid to flow along a first flow path; and (b) a second position in which only the second plunger of the pump mechanism is actuated for discharging only the second fluid through a second orifice of the fluid dispensing manifold by causing the second fluid to flow along a second flow path.
