Filling device and filling system for volumetric metering of powder

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 reduced-pressure means for generating a reduced pressure 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 second reduced-pressure generator for generating a reduced pressure on the blocking portion on the outside thereof.
