Abstract

A dosage device for dosing with high accuracy a particulate material containing a pharmacologically active substance, including a storage chamber, a rotatable dosing unit adjacent the storage chamber, and an operating unit to cause relative rotation between the dosing unit and the storage chamber. The dosing unit is provided with a plurality of upwardly opening recesses opening into said storage chamber to receive particulate material therefrom through an outlet opening from the storage chamber. Scrapers are positioned in the outlet opening immediately above these recesses to pack and level the particulate material into the recesses and level the material off with the upper surface of the dosing unit as the dosing unit rotates relative to the storage chamber. The operating unit causes an indexing of the dosing unit between discrete rotational positions in one of which one of the recesses is in direct communication with a generally upwardly extending dispensing channel so that when the unit is turned upside down, the contents of that recess will be discharged through the channel.
