Abstract

The disclosure relates to a filling device and to a filling system for volumetric metering of powder in a metering container. The filling device includes a retaining device permeable to air but impermeable to the powder. The retaining device in the course of the metering process covers a filling aperture of the metering container and a rim of the metering container encircling the filling aperture, a filling pipe which has been passed through the retaining device into the metering container, and first underpressure generator for generating an underpressure or partial vacuum on the retaining device on the side thereof facing away from the metering container. The filling pipe exhibits a blocking portion, the blocking portion being at least partially permeable to air but impermeable to the powder. The filling device includes a second underpressure generator for generating an underpressure on the blocking portion on the outside thereof.
