Fluid container with variable flue

摘要

The container (1) has a tubular extraction chimney (3) extending in an alignment with a screw locking opening (5) in the container. The extraction chimney comprises a liquid-permeable zone (18) proximate to a lower end region of the extraction chimney and adjacent to a container base of the liquid container, where liquid permeability of the liquid-permeable zone of the extraction chimney is temporarily adjusted. The fluid permeable zone has a set of openings (13, 17) in the lower end region of the tubular extraction chimney, whose opening cross section of the openings is changed.
