NOZZLE AND INHALER AND METHOD FOR PRODUCING A NOZZLE

摘要

A nozzle (12), an inhaler (Fig.l) with a nozzle (12) and a method for producing a nozzle are proposed. The nozzle comprises a hole (21) formed in a flat plate (22) by laser drilling. The hole is tapered so that it widens towards the outlet side. The hole comprises a non-circular cross section and an inner sharp edge (28). This supports breaking up of the liquid flow into droplets.
