摘要：
A dispensing device, a storage device and a method for dispensing powder are proposed. The powder is dispensed through a duct with a flat cross section to de-agglomerate the powder and to generate a spray with fine particle size. A storage champ-her for the powder may be closed by bursting elemi Burst the bursting element for discharging the powder. Preferably, the cross section of a gas supply to the storage chamber controls the gas flow during dispensing of the powder. In particular, the storage device comprises multiple storage chambers and associated ducts or nozzles, so that each dose of powder can be dispensed through a separate duct or nozzle. The powder may be forced through the duct by a gas pressure of less than 300 kPa to de-agglomerate the powder and/or to generate the spray. Preferably, the gas pressure reaches or exceeds a peak value before the bursting element bursts and, then, the powder is dispensed by a lower gas pressure.
