Abstract
A metering device can be activated by a suction airflow of a user for inhaling a powdery substance, in particular of medicinal type, which is arranged in a supply chamber and can be brought out of there into an apparent discharge standby position by removing a mouthpiece sealing cap by a metering chamber of a metering rod. The metering device provides piston-extensible tabs for sealing off the metering chamber, particularly for the facilitated opening of the metering chamber.
