       29 . A fluid dispenser device including at least one individual reservoir ( 21 ) containing a single dose of fluid, such as powder, opening means ( 40 ) being provided for opening an individual reservoir ( 21 ) each time the device is actuated, wherein the reservoirs ( 21 ) are made in the form of an elongate strip ( 20 ) comprising a plurality of individual reservoirs ( 21 ) disposed one behind another, wherein said fluid dispenser device comprises dose counter or indicator means that are marked directly on said elongate strip. 
   
   
       30 . A device according to  claim 29 , in which said dose counter or indicator means include numbers or symbols. 
   
   
       31 . A device according to  claim 29 , in which said device comprises a body, said body having a window through which said dose counter or indicator means are visible. 
   
   
       32 . A device according to  claim 29 , wherein said opening means ( 40 ) comprise perforator and/or cutter means ( 41 ) and movable support means ( 50 ), said movable support means ( 50 ) being adapted to displace an individual reservoir ( 21 ) against said perforator and/or cutter means ( 41 ) on each actuation, said displacement being performed automatically by the user inhaling. 
   
   
       33 . A device according to  claim 32 , in which said movable support means ( 50 ) are displaceable between a non-dispensing position and a dispensing position, said movable support means ( 50 ) being urged towards their dispensing position by resilient means ( 51 ), such as a spring or a spring blade, and being held in their non-dispensing position by blocking means ( 100 ). 
   
   
       34 . A device according to  claim 33 , in which said blocking means ( 100 ) are released by the user inhaling. 
   
   
       35 . A device according to  claim 33 , in which said resilient means ( 51 ) are deformable between a rest position, in which they do not urge the movable support means ( 50 ) towards their dispensing position, and a stressed position, in which they urge said movable support means ( 50 ) towards their dispensing position, said resilient means ( 51 ) being deformed manually into their stressed position before the user inhales. 
   
   
       36 . A device according to  claim 35 , in which said device comprises a body ( 10 ) and a cap ( 11 ;  11 ,  12 ) that is movable between a closed position and an open position, opening the cap ( 11 ;  11 ,  12 ) deforming the resilient means ( 51 ) into their stressed position. 
   
   
       37 . A device according to  claim 29 , in which a dispenser chamber ( 70 ) is provided for receiving the dose of fluid contained in a reservoir ( 21 ) after said reservoir has been opened, said dispenser chamber ( 70 ) being connected firstly to said opening means ( 40 ), and secondly to a dispenser orifice ( 79 ) that is connected to an inhaler endpiece ( 15 ). 
   
   
       38 . A device according to  claim 37 , in which said dispenser chamber ( 70 ) contains at least one movable bead ( 75 ). 
   
   
       39 . A device according to  claim 29 , in which said opening means ( 40 ) do not move while the reservoir ( 21 ) is being opened. 
   
   
       40 . A device according to  claim 29 , in which said movable support means ( 50 ) support a guide wheel ( 30 ), said guide wheel ( 30 ) being firstly turnable about its central pin ( 39 ) so as to cause the elongate strip ( 20 ) to advance, and secondly displaceable, together with the movable support means ( 50 ), towards a dispensing position, so as to bring a reservoir ( 21 ) into contact with the reservoir opening means ( 40 ). 
   
   
       41 . A device according to  claim 40 , in which the guide wheel ( 30 ) is turned manually by the user, whereas its displacement towards the dispensing position takes place automatically by the user inhaling. 
   
   
       42 . A device according to  claim 29 , in which said opening means ( 40 ) comprise perforator and/or cutter means ( 41 ) that are adapted to cut a closure wall ( 23 ) of the reservoir ( 21 ) in such a manner that the cut portion(s) ( 24 ) does/do not obstruct the opening(s) ( 25 ) that is/are formed.
