Abstract
A device is provided for emptying a metering chamber of a powder dispenser. The dispenser includes an expulsion channel passing through the metering chamber and a device for delivering an air flow which is intended to pass along the expulsion channel to empty the metering chamber when the dispenser is actuated. A flow device is adapted to configure the air flow in such a manner that it empties the metering chamber completely. The flow device is disposed in the expulsion channel upstream from the metering chamber in the flow direction of the air flow.
