Abstract
A device for inhaling powder packaged in capsules, the device being of the type comprising a housing closed by a cover and containing means for supporting and transferring capsules, opening means for opening the capsules, a dispensing endpiece, and an air intake orifice. According to the invention, the means for supporting and transferring capsules are constituted by a moving charger provided with at least two chambers each designed to receive a respective capsule, and non-return means making it possible to use the cover to entrain the charger inside the housing in stepwise displacement in one direction only and to lock each chamber in succession in an inhalation position in which its capsule is in communication with the dispensing endpiece, and the opening means are constituted by two parallel blades respectively secured to the housing and to the cover and each adapted to cut off a respective one of the longitudinal ends of a capsule by successive displacements of the cover relative to the housing: firstly while entraining the charger in a first direction; and then on its own in the opposite direction after the charger has been locked in the inhalation position.
