A metering device activated by a user induced airstream for an inhalation of a medicinal substance. The device includes: a closure cap; a piston; a mouthpiece; and an annular chamber disposed upstream of the mouthpiece. A storage chamber stores the substance which can be moved out of the storage chamber when the closure cap is removed. A metering rod for removing the medicinal substance out of the storage chamber into an emptying-standby position. In the emptying-standby position, the metering chamber is closed by the piston. The piston is displaceable by airstream into an emptying-release position. In the emptying-release position, a metering chamber is released and the substance removed by the suction airstream. The metering device includes an outer cylinder which accommodates an inner cylinder.

Metering device for the inhalation of a pulverulent substance

A dosing device can be activated by a vacuum air stream of a user for the inhalation of a powder substance, particularly medicine, which is arranged in a supply chamber and which can be brought out of the same into an open emptying-ready position by a dosing chamber of a dosing rod when the mouthpiece-closure cap is removed. In particular, in order to improve dispensing, the provision of two air paths, of which one serves to open and empty the dosing chamber, and/or the second air path penetrates directly into a ring chamber in order to mix with the air flow containing the substance.

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.
