CA 2335639

The present invention relates to a packaged product for dispensing a liquid, comprising a liquid-containing reservoir and a porous membrane, the reservoir comprising an outlet, wherein the membrane is hermetically sealed to or around the reservoir so that fluid passing through the outlet must pass across the membrane, and in that the combination of the liquid and the membrane results in a bubble point greater than 1 kPa, when measured at ambient temperature and pressure using the packaged liquid. The invention also relates to a device for dispensing a liquid, comprising a liquid reservoir and a porous membrane, the reservoir comprising an outlet, wherein the membrane is hermetically sealed to or around the reservoir so that fluid passing through the outlet must pass across the membrane, and wherein the membrane has an average pore size of from 1 to 100 micrometers and a thickness of less than 1mm.

L'invention concerne un produit emballé permettant de distribuer un liquide. Ce produit comporte un réservoir de liquide et une membrane poreuse. Le réservoir comporte une sortie tandis que la membrane est hermétiquement fermée sur le réservoir ou autour de celui-ci, de sorte que le fluide s'écoulant par la sortie doit s'écouler à travers la membrane. La combinaison du liquide et de la membrane donne un point de bulle inférieur à 1 kPa, lorsqu'il est mesuré à la température et à la pression ambiantes au moyen du liquide emballé. L'invention concerne également un dispositif permettant de distribuer un liquide. Ce dispositif comporte un réservoir de liquide et une membrane poreuse. Le réservoir comporte une sortie tandis que la membrane est hermétiquement fermée sur le réservoir ou autour de celui-ci, de sorte que le fluide s'écoulant par la sortie doit s'écouler à travers la membrane. La membrane présente une dimension des pores moyenne comprise entre 1 et 100 µm et une épaisseur inférieure à 1 mm.
