    • A nozzle is provided for dispensing a liquid from a container in a desirable, nearly rectangular spray pattern. The nozzle includes an actuator having an inlet end adapted to receive liquid from the container and an outlet end, the actuator outlet end defining an outlet chamber. An insert is coupled to the actuator outlet end and defines an insert passage in fluid communication with the outlet chamber. The insert includes at least a first convex shoulder disposed downstream of the outlet chamber, and a nozzle outlet disposed downstream of the first convex shoulder. The convex shoulder may have a radius of curvature and side walls may be provided at an angle 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.
    • 提供喷嘴以用于以期望的,接近矩形的喷雾模式从容器中分配液体。 喷嘴包括致动器,其具有适于从容器接收液体的入口端和出口端,致动器出口端限定出口室。 插入件联接到致动器出口端并且限定与出口室流体连通的插入通道。 所述插入件包括设置在所述出口室下游的至少第一凸肩和设置在所述第一凸肩的下游的喷嘴出口。 凸肩可以具有曲率半径,并且侧壁可以以会聚角设置。 可以在一定范围内提供曲率半径和收敛角度,以使用典型的气溶胶罐压力以期望的流速获得所需的喷雾图案。
