A one-piece spray nozzle for the metered mixing and dispensing of a carried fluid with a primary carrier fluid comprising a first connection for connecting the nozzle to a source of the carried fluid and a second connection adapted for carrying the nozzle to a source of the primary carrier fluid. A jet passageway communicating with the second connection projects the primary carrier fluid in a stream. A mixing chamber is aligned with the jet passasgeway but is separated from the jet passageway by an air gap or recess. A passage extending between the first connection and the mixing chamber conducts the carried fluid under gravity to the mixing chamber. The mixing chamber is sized so that the stream of the primary carrier fluid does not contact the walls of the mixing chamber but draws a stream of a secondary carrier fluid from the air gap or recess through the mixing chamber. The stream of the secondary carrier fluid draws the carried fluid into the chamber to mix with the primary carrier fluid.

A spray nozzle for attachment to the top of a container of a concentrated carried fluid for the metered mixing and dispensing of the carried fluid with a primary carrier fluid, the nozzle comprising: a body having first connection means for connection to the top of the container; second connection means for connection to a source of primary carrier fluid, a recess in the body in communication with the atmosphere; a jet passageway interconnecting the second connection means and the recess for projecting the primary carrier fluid in a stream; a mixing chamber extending from the recess opposite from the jet passageway is jetted across the recess and through the mixing chamber; and a passage for delivery of the carried fluid from the first connection means into the mixing chamber by inverting the container to which the body is connected; the internal dimensions of the mixing chamber being sufficiently larger than the stream of the primary carrier fluid projected through the mixing chamber that the stream of the primary carrier fluid does not contact the wall of the chamber and draws a stream of air from the recess through the mixing chamber, the air stream in the chamber drawing the carried fluid from the passage into the chamber to mix with the stream of the primary carrier fluid.
