Abstract:
1. 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 ).
