Beschreibung
Zusammenfassung:	A nozzle is provided herein for ophthalmic dispensers which is configured to accommodate microdosing. The nozzle includes a converging pathway. Preferably, the pathway converges so as to impart momentum to liquid passing therethrough through an increase of velocity. A tapered portion may be provided flared openly from the inlet to best accept liquid flow thereinto and provide a funneling effect into the flowpath. Preferably, the flowpath terminates at an outlet which is internally un-radiused and circumscribed by a chamfered surface.
