A liquid dispenser device for being associated with a liquid reservoir (R), said device comprising: a chamber ( 10 ) provided with an inlet valve ( 5, 15 ), an outlet valve ( 32, 232 ), and a piston ( 3 ) that is suitable for varying the volume of the chamber; a liquid dispenser orifice ( 25 ); and a pusher ( 2 ) that is axially displaceable down and up between a rest position and a depressed position; the dispenser device being characterized in that the pusher ( 2 ) includes an elastically-deformable wall ( 212 ) that is thus displaceable relative to the remainder of the pusher, the piston ( 3 ) being in contact, at least momentarily, with the deformable wall ( 212 ), so as to be urged in displacement relative to the remainder of the pusher while the wall is being deformed, in such a manner as to open the outlet valve.
