The liquid is enclosed in a resiliently deformable container (1), the neck of which has a microfiltering membrane (9) which is permeable to the liquid but impermeable to air when wet. Since the container resiliently recovers its shape after it is deformed, the liquid remaining in contact with the outside of the membrane after use is sucked back in and the membrane is kept moist until the next time the container is used.

On enferme le liquide dans un récipient élastiquement déformable (1) dont le goulot est obstrué par une membrane microfiltrante (9) perméable au liquide mais imperméable à l'air lorsqu'elle est mouillée. Par récupération élastique de forme du récipient après déformation, on aspire le liquide extérieurement au contact de la membrane après une distribution et on maintient la membrane humectée jusqu'à la distribution suivante.
