The invention relates to a bottle for packaging a liquid (1) with dropper delivery comprising a reservoir (2) with an elastically deformable wall that can be reversed by letting air into the receptacle, surmounted by a dispensing head for the liquid comprising a drop-counting end-piece (5) protruding to the outside of the bottle and an anti-bacterial filtering membrane (7), made partially hydrophilic and partially hydrophobic which is interposed across the path of the liquid and of the air, at the base of the said end-piece. The dispensing head comprises an insert (4) with a recessed body which contains a porous pad (8) regulating the flow of liquid placed downstream of the reservoir and upstream of a chamber (9) delimited downstream of the said membrane. At the base of this insert on the inner side of the bottle, longitudinal arches (13) supporting a central pellet (11) make star-shaped passageways radially guiding the air that enters the bottle after having passed through the porous pad.
