DUAL ORIFICE NOZZLE AND METHOD FOR INTERNALLY COATING CONTAINERS Abstract A nozzle, nozzle assembly and method for internally coating containers uses a dual orifice nozzle and method to direct divergent spray patterns at separate interior surface portions of the container where the coating liquid is most needed and to minimize misting, overspray and waste. The nozzle comprises a generally cylindrical body having a forward portion, a middle portion, a rear portion, a first conduit extending longitudinally therethrough terminating in a first opening disposed in the forward portion, and a second conduit extending longitudinally therethrough terminating in a second opening formed in the forward portion of the body. The first and second openings are oriented at an acute angle with respect to a central longitudinal axis of the nozzle to direct the separate sprays of coating liquid from the body generally in separate patterns diverging from the central longitudinal axis of the nozzle. The conduits are suited to receive airless nozzle inserts that direct the separate spray patterns at the distinct interior portions. In the internal coating method, a flow of coating liquid is divided into first and second flow portions, with the first flow portion directed toward one interior surface portion of the container and the second flow portion toward another separate interior surface portion.
