Abstract:
1. An inhaler for powdery substances, comprising: a rotatable mouthpiece connected to a stationary housing, where the housing has external threads; a rotary part rotationally fixed with the mouthpiece containing a suction air channel leading to the mouthpiece; a storage chamber for storing therein the powdery substance and having a rotatable cover, where disposed below the cover is a rotationally fixed rotor configured to contact the substance in the storage chamber; a linearly movable non-biased dipping plunger rotationally fixed with and projecting through the rotary part and the cover, where the dipping plunger has formed therein at one end a dosing chamber for apportioning a specific amount of substance from said storage chamber and moving the amount of substance to a transfer position; and a closure cap for covering said mouthpiece, where the closure cap has an interior portion containing internal threads configured to engage the external threads on the housing, wherein when the closure cap is unscrewed and removed, the dipping plunger and the dosing chamber are moved into a ready-to-empty position, wherein rotation of the closure cap when the internal and external threads are engaged causes rotation of the rotary part, the mouthpiece, the dipping plunger, rotor, and the storage chamber cover.
