Abstract

Disclosed is an apparatus for diluting and dispensing fluid concentrates which comprises a frame having a least one compartment therein for insertion of a liquid holding container. Mounted within the frame is a water valve housing which is adapted to interface with a venturi housing affixed to the liquid holding container. The water valve housing has affixed thereto a valve which is manually actuated. In response to the depression or release of the actuation means, the valve is substantially either fully open or fully closed. The water valve housing includes locking means for preventing the valve from being operated by the manual actuation means when the liquid holding container is not properly inserted into the dilution station. The refill modules of the present invention include the venturi housing and liquid holding container mentioned above. The venturi housing has an unlocking means extending therefrom which engages and unlocks the locking means of the water valve housing when the refill is properly installed in the dilution station. Insertion of the refill makes a sealed connection to the water valve, vents the refill, locks the refill into position and releases the operation…
