Abstract: An aerosol dispensing device for placement on an aerosol container having a valve stem. The device includes an actuator adapted to operate the valve stem. A spray nozzle insert is positioned in the actuator. The spray nozzle insert includes an end wall having a spray orifice therethrough. A cylindrical wall connected to the inner side of the end wall is arranged concentric with the spray orifice. The spray nozzle insert has at least two snap fingers at a radial distance outside the cylindrical wall. The actuator has at least two guiding ribs configured to guide each snap finger upon positioning the spray nozzle insert in the actuator. The snap finger has a snap member which is snapped behind an inward end of the guiding rib.

Abstract: An actuator for dispensing the liquid contents of a container in the form of a spray includes an actuator cap, an axial spray channel with an orifice for spraying the contents of the container, and an axial feed channel for connection a container outlet to the spray channel. A breakup wedge is provided in the feed channel such that it splits the feed channel into two sub channels, each connected via a side inlet opening with an inlet portion of the spray channel. Thus, in use, a flow of content is split into two sub flows by the breakup wedge, which sub flows subsequently collide in the inlet portion of the spray channel causing a turbulent flow of the liquid product in the inlet portion of the spray channel, which turbulent flow is guided by the spray channel towards and out of the dispensing opening.
