Abstract
A fluid dispenser having a reservoir (R) containing fluid (P) and air (A), the reservoir (R) forming an assembly opening (11); a fluid dispenser cannula (12) in communication with the reservoir (R); and an actuator member (2) engaged in the assembly opening (11), for supplying the dispenser cannula (13) with fluid (P). The actuator member (2) has a deformable membrane (23) that defines an outside face (231) forming a pusher (24), and an inside face (232) that is in contact with the air (A) of the reservoir (R), when the dispenser cannula (12) is in contact with the fluid (P) of the reservoir (R).
Claims11
A fluid dispenser, in particular of the dropper type, comprising:
- a reservoir containing fluid and air, the reservoir forming an assembly opening;
- a fluid dispenser cannula in communication with the reservoir, the dispenser cannula forming a dispenser end that is advantageously suitable for forming a drop of fluid that separates from the dispenser end by gravity;
- and
- an actuator member engaged in the assembly opening, for supplying the dispenser cannula with fluid coming from the reservoir;
- the dispenser being characterized in that the actuator member comprises a deformable membrane that defines an outside face forming a pusher, and an inside face that is in contact with the air of the reservoir, when the dispenser cannula is in contact with the fluid of the reservoir.
