Assembly for dispensing fluids from multiple containers, while simultaneously and instantaneously venting the fluid containers

An apparatus for dispensing fluids from multiple containers, while simultaneously and instantaneously venting the fluid containers, said apparatus comprising:

• at least two containers, each for containing fluid;
• manually operable pumping means for pumping fluid from the containers to dispense the fluid from the apparatus, said pumping means comprising (i) pump actuation means for actuating and deactuating said pumping means, (ii) a reciprocating fluid conduit, which reciprocates upon actuation and deactuation of said pump actuation means and (iii) a discharge nozzle for dispensing the fluid from said apparatus upon actuation of said pumping means;
• manifold means connected to an outlet end of each of the fluid containers, said manifold means providing at least one fluid discharge opening and at least one vent opening for each container;
• at least one hollow fluid transfer dip tube for each container, each dip tube being connected to a respective fluid discharge opening in said manifold means and extending into a respective fluid container, for withdrawing fluid from the respective container upon deactuation of said pumping means;
• and
• valve means connected to the reciprocating fluid conduit of said pumping means and engageable with said manifold means, said valve means opening and closing the fluid discharge openings and air passage to and from the vent openings of said manifold means upon a corresponding pumping actuation and deactuation of said pump actuation means.
