A spray nozzle for producing an asymmetrically distributed fluid discharge pattern such as for use in a container coating application is provided. The spray nozzles includes a body portion having an internal fluid passageway which terminates in a substantially hemispherical dome shaped end wall. A discharge orifice is provided in the end wall which is produced by superimposing on each other an approximately round opening and an elongated opening having opposed rounded ends. The elongated opening having a length greater than a diameter of the round opening and the round opening and the elongated opening defining respective edges of the discharge orifice which extend at different angles relative to a longitudinal axis of the fluid passageway. The resulting orifice produces a fluid discharge pattern wherein the amount of fluid discharged tapers in a continuous, non-linear manner from the location of maximum discharge to points of minimum flow at either end of the discharge pattern.
