A nozzle is provided for dispensing a liquid from a container (12) in a desirable, nearly rectangular spray pattern. The nozzle includes an actuator (48) having an inlet end (52) adapted to receive liquid from the container (12) and an outlet end (58), the actuator outlet end defining an outlet chamber (76). An insert (60) is coupled to the actuator outlet end and defines an insert passage in fluid communication with the outlet chamber (76). The insert (60) includes at least a first convex shoulder (90) disposed downstream of the outlet chamber, and a nozzle outlet disposed downstream of the first convex shoulder (90). The convex shoulder (90) may have a radius of curvature and side walls may be provided at an angel of convergence. The radius of curvature and the angle of convergence may be provided within certain ranges to obtain the desired spray pattern at the desired flow rate using typical aerosol can pressures.
