  • Patent number: 5769073
    Abstract: A device for dispensing doses of powdered material comprises a housing which houses a cylindrical container. The container has a number of helically arranged compartments each of which contains a respective dose of powdered material. In order to dispense the material from a compartment, that compartment is moved into registry with an airway in the device by means of an indexing mechanism, and the user sucks on a mouthpiece of the housing, which mouthpiece communicates with an air inlet via the airway. The flow of air through the airway ejects the dose of material. The container can constitute a replaceable cartridge. The device is particularly suitable for use as an inhaler for dispensing powdered medicament.
