In an apparatus for inhaling pulverised powder, the powder is retained in a closed cylindrical housing mounted on a bearing surface which is supported in an open-ended tube. The bearing surface incorporates a fan, and is mounted on a spindle, the spindle having a pointed end which is inserted into a slot in the bearing member. Thus as air is drawn through the tube, the fan and bearing member rotate to distribute the powder. |
