THE PRESENT INVENTION RELATES TO A BOTTLE FOR PACKAGING A LIQUID TO BE DISTRIBUTED DROP BY DROP COMPRISING A RESERVOIR THE WALLS OF WHICH CAN BE REVERSIBLY ELASTICALLY DEFORMED BY LETTING AIR INTO THE CONTAINER, SURMOUNTED BY A LIQUID DISPENSING HEAD COMPRISING A DROPPER TIP (1) PROTRUDING FROM THE BOTTLE AND AN ANTI-BACTERIAL FILTERING MEMBRANE (6), THAT IS PARTIALLY HYDROPHILIC AND PARTIALLY HYDROPHOBIC, INTERPOSED ACROSS THE PATH OF THE LIQUID AND THE AIR, AT THE BASE OF THE SAID TIP (1). IN THE DISPENSING HEAD, THE PROPOSAL IS TO CREATE THE TIP (1) BY ITSELF OUT OF A MATERIAL CONTAINING A BACTERICIDAL AGENT THAT HAS THE EFFECT OF PREVENTING ANY BACTERIAL GROWTH ON THE SURFACE OF THE SAID TIP (1) ON THE OUTSIDE OF THE ANTIBACTERIAL MEMBRANE (6). A POROUS CORE (7) IS ADVANTAGEOUSLY POSITIONED INSIDE THE CHANNEL (3) THROUGH WHICH LIQUID IS EXPELLED AND AIR IS ADMITTED. FIGURE 4
