Abstract
The invention relates to a packaging device for a liquid that is to be dispensed drop by drop, comprising a container (1) with manually elastically deformable walls, which ends in a rigid neck (3) in which a head (4) for dispensing the liquid is mounted. A membrane (31) which is both hydrophilic and hydrophobic, advantageously antibacterial, is arranged in the dispensing head (4) across the passage of the liquid towards a duct expelling it to the outside. This membrane allows external air to enter the container (1) once the liquid has passed through it in the expulsion phase, and the bottle reverts elastically to its initial shape after each dispensing operation. A frangible partition (7) isolates the membrane from the liquid contained in the bottle until the time of first use whereupon it is fractured by a striker secured to the said dispensing head (4).
