ABSTRACT:
A liquid container having a top opening, a base, and an extraction chimney which extends into the container and which is in alignment with the top opening is presented. The extraction chimney is intended for the withdrawal of liquid by a liquid-withdrawal element that is introduced into the liquid container through the extraction chimney. The extraction chimney has a liquid-permeable zone in its bottom region, adjacent to the liquid container base. The liquid permeability of the liquid-permeable zone of the extraction chimney can be adjusted between a setting for minimal liquid permeability and a setting for greater liquid permeability. The extraction chimney can be adjusted while the extraction chimney remains in the liquid container.
