CA 2646484

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).

L'invention concerne un récipient de liquide (1) avec une ouverture supérieure (11) et une cheminée d'évacuation (17) en forme de tube rejoignant l'ouverture (11) dans le récipient, laquelle cheminée comprend dans sa partie extrême inférieure une zone perméable au liquide ayant la forme d'un élément de résistance à l'écoulement de faible porosité (27), de sorte que l'échange de liquide entre la cheminée d'évacuation (17) et l'espace intérieur l'entourant (37) peut s'effectuer à travers l'élément de résistance à l'écoulement (27). Un autre aspect de l'invention est la rainure de ventilation formée par un renfoncement radial (47) de la paroi d'enveloppe (49) de la cheminée d'évacuation dans sa partie supérieure, laquelle rainure assure dans une mesure suffisante une ventilation de l'espace intérieur (47) au-dessus du niveau de liquide (41).
