a dispensing line connecting the container to the constriction portion of the Venturi tube, wherein the dispenser body comprises a bent portion through which the dispensing line passes;
wherein flowing of fluid from the fluid source through the Venturi tube causes a volume of the liquid to be drawn into the Venturi tube via the dispensing line and wherein the drawn liquid and the fluid are mixed and dispensed via the outlet; and
