Improved device for oral or nasal administration of powdered, volatile or vaporized compositions by inhalation

摘要

To use the appliance to deliver a powder or other volatile composition, for oral or nasal inhalation, the container retainer (20) is set at the front wall of the appliance body and next to the jet or mouthpiece. The air inlet extends through the front wall into the chamber. The limit (22) is positioned within the sleeve (16) in relation to the retainer, so that it is held in place and the container which projects from the chamber (12) is against the limit when the sleeve is rotated in relation to the wall of the body to separate the projecting half section of the gelatine container from the remaining half section.
