<p>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).</p> |
