1. A fluid dispenser comprising:
- a stationary body (1) including at least one stationary gear (110, 122),a fluid reservoir (2) disposed in said body so as to be axially displaceable relative to said body,a dispenser member mounted on said reservoir (2), anda dose indicator device, including a counter element (20) that is displaceable axially and in rotation relative to said body (1), for indicating the number of doses of fluid that have been dispensed or that remain to be dispensed from said reservoir,wherein said counter element (20) cooperates, while the dispenser is being actuated, firstly with said at least one stationary gear (110, 122) of said body, and secondly with said reservoir (2), so that the dose indicator device is actuated once the dispenser has performed a predetermined incomplete actuation stroke, even if the dispenser does not perform a complete actuation stroke.

22. A fluid dispenser comprising:
-
a stationary body (1) including at least one stationary gear (110, 122); a fluid reservoir (2) disposed in said body so as to be axially displaceable relative to said body; a dispenser member mounted on said reservoir (2), being actuated when said reservoir is axially displaced relative to the stationary body by a predetermined amount, for dispensing a dose of fluid from said reservoir; a dose indicator device for indicating the number of doses of fluid that have been dispensed or that remain to be dispensed from said reservoir, said dose indicator device including a counter element (20) that is displaceable axially and in rotation relative to said body (1), wherein when the dispenser member is actuated, said counter element cooperates firstly with said at least one stationary gear (110, 122) and secondly with said reservoir (2); first safety means for actuating the dose indicator device once the dispenser has performed a predetermined incomplete actuation stroke, even if the dispenser does not perform a complete actuation stroke; and second safety means for preventing the fluid from being expelled again until said dispenser has completed the predetermined incomplete return stroke, said dispenser and said dose indicator device being capable of being actuated once again, once the predetermined incomplete return stroke has been performed, even if the dispenser does not perform the complete return stroke and said dispenser is actuated once again before returning to its rest position.
