Abstract: An aperture plate 1 comprises an inlet surface 2 for receiving a liquid to be aerosolised, an outlet surface 3 and a plurality of apertures 4 extending therebetween. The apertures 4 are tapered from an inlet opening 10 at the inlet surface 2 to an outlet or exit opening 12. The aperture plate 1 is convex in the direction of the inlet openings 10 and concave in the direction of the exit openings 12. The aerosol exits on the concave side of the aperture plate. The aperture plate of the invention generates an aerosol plume which converges and is particularly suitable for application to the eye.

Abstract: A method for aerosolising a liquid comprises the steps of: —providing an aperture plate having at least 100 outlet holes per mm; delivering liquid to the aperture plate; and vibrating the aperture plate to produce an aerosol. The viscosity of the liquid is in the range of from 1 to 15 cP and the surface tension of the liquid is in the range of from 72 to 0.5 mN/m. The output rate of the generated aerosol is greater than 0.01 mL/min.
