Claim:
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; a linearly movable non-biased dipping plunger rotationally fixed with the rotary part having formed therein at one end a dosing chamber for apportioning a specific amount of substance from the storage chamber and moving the amount of substance to a transfer position in fluid communication with the suction air channel, where the dipping plunger has an end opposite the dosing chamber having a latching head; and a closure cap for covering the mouthpiece, where the closure cap has an interior portion containing internal threads configured to engage the external threads on the housing and a docking structure configured to removably latch onto the latching head such that when the closure cap is unscrewed the docking structure pulls the dipping plunger and the dosing chamber into a ready-to-empty position and when the cap is removed the docking structure disengages from the latching head.
