Liquid receiving bottle with drop by drop dispensing head

Drop dispensing bottle comprising:

• a reservoir with an elastically deformable wall that can be reversed by letting air into said reservoir through a dispensing head, wherein the dispensing head includes
• an insert with a hollow body,
• a delivery end-piece as an extension of said body that is pierced with a central channel leading to an expulsion orifice, and
• an anti-bacterial filtering membrane partially hydrophilic and partially hydrophobic that is mounted across said insert at the basis of said delivery end-piece in order to allow the passage of a liquid in the direction of delivery and, in the reverse direction, the passage of air required to enter in compensation after a delivery of liquid,
• said insert containing a porous pad regulating the flow of liquid passing through it in the direction of said membrane,
• wherein the insert ends beyond said pad, on the side opposite to the delivery end-piece, with a base forming longitudinal arches curved radially and supporting a central pellet which make between them, passageways open to a radial flow of the entering air leaving the drop dispensing head,
• through which the liquid is delivered under an effect of a pressure applied against said wall, in which said dispensing head is mounted in a sealed manner by the insert in a neck of the bottle, in communication with said reservoir, and in which the anti-bacterial filtering membrane, partially hydrophilic and partially hydrophobic, is mounted across said insert at the base of said end-piece, in order to allow the passage of the liquid in the direction of delivery and, in the reverse direction, the passage of air required to enter the bottle in compensation after a delivery of liquid, characterized in that the base of the insert ends inside said reservoir with arches providing passageways for a radial circulation of the air entering the bottle through said pad to the periphery of the reservoir,
• wherein the insert is mounted in the neck of the bottle with the base of the insert configured to extend beyond the neck and to a narrowing portion inclined toward the peripheral wall of the bottle so that the entering air, which is directed radially to the peripheral wall of the bottle by obstruction of the central pellet, is guided in a laminar flow along the said wall.
