Abstract: The present dropper comprises an inner container provided with two elastically deformable portions: an ejection drip portion and a suction filling portion; a pusher actuates on this inner container by means of a to-and-fro motion within an outer container. By removing the safety cover the pusher can be operated and, in turn, it actuates compressing the ejection drip portion of the inner container until the liquid material comes out through the drip opening of the drip nozzle. In order to refill the dropper, the inner container is removed, its drip nozzle is applied to the refill liquid material and the filling portion is cross-sectionally compressed and decompressed by suction.
