Assembly for simultaneous dispensing of multiple fluids

An apparatus for the simultaneous dispensing of at least two different fluids in a consistent, pre-determined ratio, the apparatus comprising:

• two fluid containers, each fluid container having a fluid container neck opening,
• manually operable trigger activated pumping means having a pump chamber and a pump fluid passageway,
• coupling means for removably joining the pumping means to the fluid containers,
• venting means for allowing instantaneous equalization between ambient air pressure and the pressure within each fluid container,
• means for closing the venting means to prevent fluid from leaking from a fluid container,
• two hollow dip tubes, each dip tube having a top end opening which is in fluid communication with a fluid transfer channel, which is itself in fluid communication with the pumping means, each dip tube having a bottom end, extending into the interior of a respective one of the fluid containers,
• fluid transfer means for transferring fluid from at least one of the fluid containers to the pumping means, the fluid transfer means comprising a fluid transfer structure having a fluid transfer channel which is, along its bottom side, in fluid communication with the open top ends of the dip tubes and along its top side in fluid communication with a fluid conduit which extends into and is itself in fluid communication with the pump chamber of the pumping means, and
• valving means for opening and closing the dip tubes, in response to actuation of the pumping means, which, when the pumping means is not actuated, produces an interruption in the fluid communication between the fluid transfer channel and the dip tubes.
