Counter for a device for dispensing a fluid or powder product

A dose counter for counting the number of doses of fluid or powder that have been dispensed or that remain to be dispensed from a fluid dispenser device, said counter including a first rotary counter element (410) forming a units wheel, and a second rotary counter element (420) forming a tens wheel, said first and second counter elements (410;

• 420) co-operating with each other to define said number of doses, said first counter element (410) co-operating with an actuator member (430) that is adapted to cause said first counter element (410) to turn each time said actuator member (430) is actuated, said first rotary counter element (410) including means (418, 419) that are adapted to cause said second counter element (420) to turn on every tenth actuation of said actuator member (430), said first and second counter elements (410;
• 420) turning about a common pivot pin (461), said counter being characterized in that said actuator member (430) includes an opening that is mounted in rotary manner on said pivot pin (461), a substantially rigid and substantially rectilinear tab (431) extending radially from said opening, said tab (431) supporting a lug (4310) that is adapted to co-operate with the first counter element (410) on each actuation, said tab (431) being extended on another side of said pivot pin by a substantially rigid and substantially rectilinear portion (432) that extends radially from said opening, and that is connected to an elastically-deformable portion (434) of shape that is curved and that passes, at least in part, around the pivot pin (461), said deformable portion (434) being extended by a support portion (436) that is substantially rigid and that supports an actuator element (435), such that, on each actuation, said actuator element (435) is moved in translation and transmits this traction force to said elastically-deformable curved portion (434), causing said rectilinear portion (432) and said tab (431) to turn about said pivot pin (461).
