A device for inhaling powder-type substances includes a plurality of substance containers that can be moved successively into an emptying position, wherein the substance containers—which are not connected to one another—are accommodated in direct contact with one another in a guide unit attached to the device and can be moved by contact pressure propagating among the substance containers. The guide unit has a drive wheel with accommodating forms separated by drive teeth. The substance container in the emptying position is located in an accommodating form of the drive wheel. A substance container for a device for inhaling powder-type substances has two sub-regions, each separately having an amount of the substance, and both sub-regions have an openable, pierceable cover. A method for filling a device for inhaling powder-type substances uses a plurality of substance containers that can be moved successively into an emptying position.

A device for dispensing a substance which can be discharged by air, comprising a discharge nozzle, a pump device, an air guiding channel joining the pump device to the discharge nozzle, a strip-shaped element which is mounted in the device and which comprises chambers which contains the substance and which are embodied successively over the entire length in the strip-shaped element, a reservoir and an emptying region, the strip-shaped element having several layers. The second layer of the chamber, which is located in the emptying region, is already removed in the partial region comprising said chamber and the air subjected to the forced flow flows through the air-guiding channel merging into the opening plane in the chamber, for advantageously emptying. Also, with respect to the pump device, the pump wall comprises a pressure region and several convex regions and when the convex regions are pressurised, the convex regions remain essentially the same and/or the device comprises a receiving region which is designed as a closed receiving chamber within the device, and that the partial region is located, during an anticipated movement, in the emptying region forming a movable part of the wall of the capture chamber.
