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 comprising a base body, with a rotary counter element being assembled in said base body on a pin forming the axis of rotation, said rotary counter element co-operating with an actuator member that is adapted to cause said rotary counter element to turn each time said actuator member is actuated, said actuator member includes fastener means for fastening to the base body and being arranged on a first side of said pin, and a substantially rigid support portion that is arranged on a second side of said pin, said support portion supporting an actuator element so that, on each actuation, said actuator element is moved in translation, said support portion being connected to said fastener means via an elastically-deformable portion that surrounds said pin, said support portion being extended towards said pin by a substantially-rectilinear flexible branch that supports a lug that is adapted to co-operate with said counter element on each actuation; wherein the rotary counter element is a first rotary counter element that is provided with a first peripheral edge portion including counter indices distributed over said periphery, and that is provided with a first set of teeth; and the dose counter comprising a second rotary counter element that is provided with a second peripheral edge portion including counter indices distributed over said periphery, and that is provided with a third set of teeth; wherein the actuator member is movable between a first position and a second position, said flexible tab adapted to co-operate with said first set of teeth of said first counter element, so as to cause said first counter element to turn when said actuator element is moved from its first position to its second position; said first counter element including at least one finger that is movable between a non-deformed position and a deformed position, which deformable finger is adapted, in its deformed position, to co-operate with said third set of teeth of said second counter element, so as to cause said second counter element to turn; said base body supporting said actuator member and said first and second counter elements, said base body including a cam that is adapted to deform said at least one deformable finger towards its deformed position.
