The container comprises: a wall, and a bottom that is connected to the wall and has at least one bore through which compressed gas from the compressed gas source can be conducted into the interior space. A swirl plate made of a porous material is provided at the bottom. Compressed gas can be conducted through the porous swirl plate into the interior space to aerate at least a portion of the powdered medium without conveying the powdered medium out of the interior space to the dispensing unit.
