发明名称 LIQUID CONTAINER WITH EXTRACTION CHIMNEY
摘要 The invention concerns a liquid container (1) with an upper opening (11) and a tube-shaped withdrawal chimney (17) which extends into the container through the opening (11) which has a liquid-permeable zone in the form of a finely-porous flow resistance element (27) in its lower end region such that liquid exchange can take place between the withdrawal chimney (17) and the container inner space (37) which surrounds it via the flow resistance element (27). Another aspect of the invention is a venting groove formed by a radial recess (47) of the casing wall (49) of the withdrawal chimney in its upper region which ensures adequate venting of the space (47) above the liquid level (41).
