Patent ID: 8322337

Claim:
A fluid dispenser device comprising: a body; an elongate flexible strip supporting a plurality of reservoirs each containing a dose of fluid or powder; reservoir-opening means for opening a respective reservoir on each actuation; first displacement means for causing said flexible strip to advance at least one of before, during and after each actuation, so as to bring a full reservoir into register with said reservoir-opening means; and second displacement means for displacing a full reservoir against said opening means each time the device is actuated; wherein a leading end of said flexible strip, in the advance direction of said strip, is fastened to a receiver element that is rotatably mounted relative to said body, said receiver element being adapted to exert a traction force on said elongate strip, said traction force being independent of said first displacement means, said traction force being applied on said strip when said second displacement means move the empty reservoir away from said opening means after each actuation; said opening means comprises a needle that does not move relative to said body, a reservoir being displaced against said needle each time the device is actuated, said needle penetrating into said reservoir so as to empty the reservoir by an inhalation flow.
