摘要:
A dispensing device, a storage device and a method for dispensing powder in which 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 chamber for the powder may be closed by a bursting element which is burst by pressurized gas for discharging the powder, the gas pressure reaching or exceeding a peak value before the bursting element bursts so that the powder is dispensed at a lower gas pressure. 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. The storage device can have multiple storage chambers and associated ducts or nozzles, so that each dose of powder can be dispensed through a separate duct or nozzle.
