Title:	Valve for aerosol container
Abstract:	Valve for an aerosol container for dispensing a suspension of a substance in a liquid propellant contained therein. The valve comprises a valve body (1) having at least one orifice (16) to allow a quantity of the suspension to pass from the container into the valve. The valve further comprises a ring (18) disposed around the valve body (1), the ring being positioned below the at least one orifice to reduce the volume of suspension that can be accommodated within the container below the at least one orifice when the container is orientated with the valve at the bottom, the ring having at least one portion of reduced axial thickness to provide a trough (19) around the valve body below the at least one orifice.
