Liquid Distribution Head, comprising a Filtration tank that controls the expulsion of fluid and the entry of air into the interface between the inside and outside of a Liquid container, where the expulsion of the liquid Filtration Device comprises a tubular filter Selectively permeable Membrane Wall.
The invention concerns a liquid dispenser head which is designed to be mounted on a bottle containing a liquid and comprises a filtering device (26) forming an interface between the inside and the outside of the bottle. The filtering device comprises tubular filters (30) which are extended longitudinally so they can be plunged into the bottle, particularly tubular filters whose wall consists of a membrane that is selectively permeable to a liquid to be expelled from the bottle and made of hydrophilic material for this purpose. So that the expelled liquid can be replaced by air, the membrane forming the wall of said filter tube is made of hydrophobic material so as to be selectively air-permeable. The hydrophobic membrane also filters bacteria in the air.CABEZAL DE DISTRIBUCION DE LIQUIDO, CON UN DEPOSITO DE FILTRACION QUE CONTROLA LA EXPULSION DE LIQUIDO Y LA ENTRADA DE AIRE EN LA INTERFAZ ENTRE EL INTERIOR Y EL EXTERIOR DE UN RECIPIENTE DE LIQUIDO, PARA LA EXPULSION DE LIQUIDO EL DISPOSITIVO DE FILTRACION TIENE FILTROS TUBULARES DE PARED DE MEMBRANA SELECTIVAMENTE PERMEABLE
