A fluid dispenser device comprising: a body provided with a dispenser orifice; a plurality of individual reservoir each containing a dose of powder; dispenser means (50, 80) for dispensing a dose of fluid on each actuation, said dispenser means including reservoir-opening means comprising a reservoir-perforator element that is stationary relative to the body, and second reservoir displacement means for displacing a full reservoir against said perforator element, thereby opening it and releasing the dose of powder, said second displacement means being controlled by the user inhaling; and a dose counter for indicating the number of doses that have been dispensed or that remain to be dispensed, said device being characterized in that said counter comprises: · a first rotary counter element provided with a first surface including first indicator means, such as digits, and provided with at least one first set of teeth (128, 129); · a second rotary counter element provided with a second surface including second indicator means, such as digits, and provided with at least one second set of teeth (228, 229); and · a movable actuator element that is displaceable between a first position and a second position, said actuator element including a projection that is 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 while said actuator element is being displaced from its first position to its second position, said actuator element being rotatably mounted on the body, turning in a first direction bringing the projection to push a tooth of said first set of teeth of the first counter element so as to cause said first counter element to turn, and turning in the opposite direction bringing the projection to slide over said tooth so as to engage in the following tooth without causing said first counter element to turn; · said first counter element including at least one deformable finger that is displaceable between a non-deformed position and a deformed position, and that is adapted to co-operate, in its deformed position, with said second set of teeth of said second counter element, so as to cause said second counter element to turn; · said body including a cam that is adapted to deform said at least one deformable finger towards its deformed position; and · said second displacement means co-operating with said actuator element of the counter, such that when said second displacement means displace a reservoir against or away from the perforator element, the actuator element causes said first counter element to turn. · a first rotary counter element provided with a first surface including first indicator means, such as digits, and provided with at least one first set of teeth (128, 129); · a second rotary counter element provided with a second surface including second indicator means, such as digits, and provided with at least one second set of teeth (228, 229); and · a movable actuator element that is displaceable between a first position and a second position, said actuator element including a projection that is 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 while said actuator element is being displaced from its first position to its second position, said actuator element being rotatably mounted on the body, turning in a first direction bringing the projection to push a tooth of said first set of teeth of the first counter element so as to cause said first counter element to turn, and turning in the opposite direction bringing the projection to slide over said tooth so as to engage in the following tooth without causing said first counter element to turn; · said first counter element including at least one deformable finger that is displaceable between a non-deformed position and a deformed position, and that is adapted to co-operate, in its deformed position, with said second set of teeth of said second counter element, so as to cause said second counter element to turn; · said body including a cam that is adapted to deform said at least one deformable finger towards its deformed position; and · said second displacement means co-operating with said actuator element of the counter, such that when said second displacement means displace a reservoir against or away from the perforator element, the actuator element causes said first counter element to turn.
