CA 2428494

The invention concerns a device for packaging a liquid to be drip-dispensed, comprising a container (1), with a wall elastically deformable manually, and which is terminated by a rigid neck (3) wherein is mounted a liquid dispensing head (4). A membrane (31) both hydrophilic and hydrophobic, advantageously anti-bacterial, is arranged in the dispensing head (4) across the passage of the liquid to the channel expelling the liquid. Said membrane allows through outside air into the container (1) after it has been passed through by the liquid in the expelling phase and the bottle elastically recovers its initial shape after each dispensing operation. A frangible partition (7) isolates the membrane from the liquid contained in the bottle until its first use whereby it is ruptured by a striker integral with said dispensing head (4).

L'invention concerne n dispositif de conditionnement pour un liquide à distribuer goutte à goutte, comportant un récipient (1) à paroi élastiquement déformable manuellement, qui se termine par un col rigide (3) dans lequel se monte une tête de distribution du liquide (4). Une membrane (31) à la fois hydrophile et hydrophobe, avantageusement anti-bactérienne, est disposée dans le tête de distribution (4) en travers du passage du liquide vers un canal d'expulsion à l'extérieur. Cette membrane laisse rentrer de l'air extérieur dans le récipient (1) après qu'elle ait été traversée par le liquide en phase d'expulsion et le flacon reprend élastiquement sa forme initiale après chaque opération de distribution. Une cloison fracturable (7) isole la membrane du liquide contenu dans le flacon jusqu'à une première utilisation oú elle est fracturée par un percuteur solidaire de ladite tête de distribution (4).
