Dropper, in particular eye dropper

Abstract

Claimed and disclosed is a dropper, preferably an eye dropper having a detached edge area wherein a dropper insert is arranged at a dropper tip. At this detatched edge area, the dropper tip is either flushed with the frontal extremity of the dropper insert or recessed relative to the frontal extremity of the dropper insert. This dropper facilitates the dispensing and the delivery of small droplets with precise pre-determined volume from the dropper to an eye with reduced risk of injury to the eye during application of the droplets.
