Abstract: A unitary, multi-purpose, self-contained apparatus for the selection, variable dilution, mixing and dispensing of one or more fluids into a diluent stream is described. This apparatus is made from two, complimentary halves which describe the various reservoirs, line feeds, and valves used to add these fluids to an incoming diluent stream. The apparatus can be used in combination with a shower, bath, sink faucet, hose, washing machine, and dish washer and can be used to dispense soaps, shampoos, detergents, and disinfectants, or also fertilizers, insecticides and the like. The apparatus can also be used in the embalming and medical field as well as to select, dilute, mix and dispense ingredients to prepare coffee and sodas, in coin operated dispensing machines.
