  • a portion removal device with a vertical removal standpipe provided with an axial hand protection causes a liquid column to form in this standpipe over the axial wall slot when the container is being filled, the composition profile of which in the axial direction roughly corresponds to the composition profile of the container contents over the fill level.

If the hose 18, which has a greater axial length than the wall slots 10 and 15, is inflated with compressed air or with a pressure fluid, the tube lies against the mouths of the wall slots 10 and 15 and closes off the liquid columns within the extraction stand pipes 9 and 13.
