A B S T R A C T The metering device for powdered material comprises a storage container (10) for the powdered material and a discharge opening in the bottom of the storage container which is opened and closed, respectively, by a closing mechanism (12). The powdered material flows through the discharge opening into a drawing cup (13). In order to obtain a defined bulk density of the powdered material in the drawing cup (13), a vibration mechanism (14) imparts vibrations to the metering device when the dis- charge opening (11) is open. The closing mechanism (12) can be designed in the manner of a blade diaphragm, and in that case the closing mechanism (12) can be actuated by a grooved disk (17) which at the same time is a part of the vibration mechanism (14). The vibration mechanism (14) can also include a base disk (20) urging spring-biased elements (19) against a toothed ring (18) so that said elements (19) slide over the toothed ring (18), when the grooved disk (17) is rotated relative to the base disk (20), to thereby produce vibration.
