An apparatus for dispensing multiple fluids from nested containers, while simultaneously venting the fluid containers, includes a first container for containing a first fluid, a second container, nested within the first container, for containing a second fluid, and a manually operable pump for pumping fluid from the containers to dispense a mixture of the fluids from the apparatus. The pump includes (i) a pump actuator for actuating and deactuating the pump, (ii) a reciprocating fluid conduit, which reciprocates upon actuation and deactuation of the pump actuator and (iii) a discharge nozzle for dispensing the mixture of the fluids from the apparatus upon actuation of the pump. The apparatus also includes a mixing chamber for mixing the first and second fluids drawn from the first and second containers, respectively, a fluid transfer conduit for withdrawing fluid from the first container into the mixing chamber and a fluid transfer mechanism for withdrawing fluid from the second container into the mixing chamber, the fluid transfer mechanism including an auxiliary pump, attached to the reciprocating conduit, for pumping fluid from the second container to the mixing chamber upon a corresponding reciprocation of the reciprocating conduit.
