FLUID PRODUCT DISPENSING DEVICE
A fluid dispenser device including a body ( 10 ) that is provided with a dispenser opening ( 1 ) and at least one cover element ( 11; 12 ) that is displaceable between a closed position, in which it covers said dispenser orifice ( 1 ), and an open position, in which it uncovers said dispenser orifice ( 1 ), said device further including: an elongate flexible strip ( 20 ) supporting a plurality of reservoirs ( 21 ) each containing a dose of fluid or powder; reservoir-opening means ( 30 ) for opening a respective reservoir on each actuation; and displacement means ( 40 ) for displacing said flexible strip ( 20 ) before and/or during and/or after each actuation, so as to bring a full reservoir into register with said reservoir-opening means, the leading end ( 1 ) of said flexible strip ( 25 ), in the displacement direction of said strip, being fastened to a receiver element ( 20 ) that is rotatably mounted relative to said body ( 50 ), said receiver element ( 50 ) being adapted to exert a traction force on said elongate strip ( 20 ).

12 . A fluid dispenser device including a body ( 10 ) that is provided with a dispenser opening ( 1 ) and at least one cover element ( 11 ; 12 ) that is displaceable between a closed position, in which it covers said dispenser orifice ( 1 ), and an open position, in which it uncovers said dispenser orifice ( 1 ), said device further including: an elongate flexible strip ( 20 ) supporting a plurality of reservoirs ( 21 ) each containing a dose of fluid or powder; reservoir-opening means ( 30 ) for opening a respective reservoir on each actuation; and displacement means ( 40 ) for displacing said flexible strip ( 20 ) before and/or during and/or after each actuation, so as to bring a full reservoir into register with said reservoir-opening means, the leading end ( 25 ) of said flexible strip ( 20 ), in the displacement direction of said strip, being fastened to a receiver element ( 50 ) that is rotatably mounted relative to said body ( 10 ), said receiver element ( 50 ) being adapted to exert a traction force on said elongate strip ( 20 ), said rotary receiver element ( 50 ) being caused to turn while said at least one cover element ( 11 , 12 ) is being opened and/or closed, said device being characterized in that said rotary receiver element ( 50 ) includes a set of teeth ( 55 ) that co-operates with an actuator member ( 150 ) that is secured to at least one cover element ( 11 , 12 ), said actuator member ( 150 ) comprising a toothed rod ( 160 ) which, in one of its directions of displacement, causes said rotary receiver element ( 50 ) to turn, and, in its other direction of displacement, slides over said set of teeth ( 55 ) without causing the receiver element ( 150 ) to turn.
13 . A device according to claim 12 , in which said set of teeth ( 55 ) co-operates with an anti-return device ( 250 ), such as a finger, so as to prevent said rotary receiver element ( 50 ) from turning in the direction opposite to that which is imparted thereto by said actuator member ( 150 ).
14 . A device according to claim 12 , in which said rotary receiver element ( 50 ) is caused to turn while said at least one cover element ( 11 , 12 ) is being opened.
15 . A device according to claim 12 , in which said rotary receiver element ( 50 ) is caused to turn while said at least one cover element ( 11 , 12 ) is being closed.
16 . A device according to claim 12 , in which said opening means ( 30 ) comprise a needle ( 30 ) that does not move relative to said body ( 10 ), a reservoir ( 21 ) being displaced against said needle each time the device is actuated, said needle penetrating into said reservoir ( 21 ) so as to empty it by means of an inhalation flow.
17 . A device according to claim 12 , in which said opening means ( 30 ) are controlled by the user inhaling, such that the reservoir ( 21 ) is opened and emptied simultaneously by said inhalation flow.
