A metering device for powdery substances, particularly for preparing dental and dental laboratory powder compounds. The powder compounds can be filled into a storage container (1) and fed from the storage container (1) to a vessel (9) using a discharge device. The lower region (3) of the storage container (1) is tapered, and in the storage container (1) an insert (4) is arranged, which has at least one upwardly tapering section (5), wherein the insert (4) is arranged in the tapered lower region (3) of the storage container (1). A through-passage (7) remains clear between the lower edge (6) of the tapering section (5) of the insert (4) and the tapered lower region (3) of the storage container (1). The insert (4) and/or the storage container (1) is associated with a vibration unit (8). The vessel (9) receiving the metered powder can be placed on a weighing unit (10), wherein the weighing unit (10) and the vibration unit (8) are operatively connected to each other. |
