Abstract: An aerosol spray device comprising a pressurised or pressurisable 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.

Abstract: A spray discharge assembly is provided for use with an aerosol spray device comprising a pressurizable container holding a liquid to be discharged from the device by a propellant. The spray discharge assembly incorporates an approach channel having at least one inlet and an outlet, a flow conduit upstream of the approach channel in the direction of liquid discharge for supplying fluid to be discharged to the approach channel, at least one jetting orifice through which fluid from the conduit passes and issues as a jet into the approach channel through the inlet thereof, and a discharge orifice into which fluid from the approach channel passes via the outlet thereof to issue as a spray from the device. The outlet of the approach channel is surrounded by a sharp edge, and the jetting orifice is configured for directing the jet against the sharp edge.
