Abstract
A drop dispenser including a fluid reservoir, a tube having a dispenser end and an actuation end, a fluid chamber of variable volume connected to the actuation end of the tube; a pusher that is axially movable between a high position and a low position so as to cause the volume of the chamber to vary and drive the fluid into the tube towards the dispenser end so as to form a drop of fluid; and a fastener ring including a threaded skirt for coming into engagement with the threaded neck, the tube and the chamber being secured to the ring. The drop dispenser have a mover for moving the pusher axially between the high and low positions, the mover also causing the fastener ring to turn, both so as to loosen it from the neck by unscrewing and so as to tighten it onto the neck by screw-tightening.
