<p>The invention concerns a device for dispensing an active principle in powder form, comprising a box (2-104, 4-404); an adapter (6) for inhaling or blowing the active principle; a reservoir (10) for storing the active principle in powder form; a metering chamber (16, 116) enabling to draw a specific dose of the active principle, and integral with a part (12, 200) mobile between a drawing position wherein it communicates with the storage reservoir (10), and a position ready for use; means for driving (22, 24; 124) the metering chamber between its various positions; confinement means (32, 32a, 32b; 102b, 102c) for closing at least part of the metering chamber, in its ready position. In a position releasing the drawn dose of active principle, the metering chamber (16) is arranged to communicate, right through, on one side with an air supply chamber (34, 134), and on the other side with an inhalation opening (6), and the confinement means (32, 102) are mounted sliding relative to the box (2, 102; 4 104) and arranged to close the passage passing through said metering chamber, in ready-for-use position, and to open said passage into the releasing position of said metering chamber.</p> |
