Device for distributing fluid product

A fluid dispenser device comprising:

• a body including a dispensing orifice;
• a plurality of reservoirs housed within the body, each containing a dose of fluid, the reservoirs disposed one behind the other on an elongate flexible strip;
• a perforator that is stationary relative to the body and configured to perforate each reservoir when the reservoir is pressed against the perforator;
• a first strip displacement mechanism that causes the elongate flexible strip to advance at least before or after each actuation of the device;
• and
• a second reservoir-displacement mechanism comprising an arm mounted to turn relative to the body so as to displace a full reservoir against the perforator to perforate the full reservoir;
• the first displacement mechanism including an indexer wheel rotatably mounted on the second reservoir-displacement mechanism and provided with at least one cavity that adapted to receive a respective reservoir, turning the indexer wheel causes the elongate flexible strip to advance;
• the first displacement mechanism includes an actuator member that is disposed in coaxial manner radially inside the indexer wheel, the actuator member rotatable relative to the indexer wheel, the actuator member including two deformable flexible tabs co-operating with a set of teeth formed on the other of the actuator member and the indexer wheel, such that turning the actuator member in a first direction causes the indexer wheel to turn, and turning the actuator member in a second direction, opposite to the first direction, does not causes the indexer wheel to turn, the actuator member co-operating with the body, such that when the second reservoir-displacement mechanism brings a full reservoir against the perforator, the actuator member turns in the first or second direction, and when the second displacement mechanism takes the empty reservoir away from the perforator, the actuator member turns in the second or first direction, causing the indexer wheel to turn, and thus causing the elongate flexible strip to advance during a reservoir-opening cycle;
• wherein the two deformable flexible tabs co-operate with an inner set of teeth of the indexer wheel, the ends of the tabs pushing the teeth of the inner set of teeth when turning in the first direction of the actuator member, and sliding over the teeth when turning in the second direction;
• and
• wherein the actuator member includes a groove that co-operates with a projection that is secured to the body, such that when the second reservoir-displacement mechanism displaces a full reservoir against the perforator, the projection causes the actuator member to turn in one of the directions, and when the second reservoir-displacement mechanism returns to the rest position, the projection causes the actuator member to turn in the other of the directions.
