Abstract
An aerosol spray device comprising a pressurized or pressurizable container and a spray discharge assembly mounted on the container. The spray discharge assembly comprises a valve stem moveable from a first limit position to a second limit position to effect spray discharge from the device, a spray outlet region having an outlet orifice from which fluid from the container is discharged, and a flow conduit for supplying fluid from the container to the spray outlet region. The flow conduit has at least one first inlet for liquid from the container and at least one second inlet at the same distance along the conduit as the first inlet(s) or downstream of the first inlet(s) for propellant gas from a headspace of the container. A valving arrangement is adapted such that movement of the valve stem from its first to second limit position opens the first and the second inlets to cause a bubble laden flow to be created in the flow conduit and movement of the valve stem back to its first limit position closes the first and the second inlets.
