Abstract: Fluid product dispenser comprising:



a reservoir (R) having a neck (1),
a dispensing head (T) mounted axially on the neck (1) and comprising a dispensing member (P), and a fastening ring (F) engaging both the neck (1) and the dispensing member (P), the fastening ring (F) comprising a skirt (2) including a plurality of internal latching projections (211),
characterised in that the neck (1) defines externally a plurality of horizontal latching shoulders (130) oriented downward and a plurality of release ramps (112), the latching projections (211), initially engaged below the horizontal latching shoulders (130), being constrained radially outward on the release ramps (112) by rotation of the skirt (2) around the neck (1), thus releasing the latching projections (211) of their latching engagement from below the latching shoulders (130).

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).
