The invention relates to a bottle for packaging a liquid with dropper delivery comprising a reservoir with an elastically deformable wall that can be reversed by letting air into the receptacle, surmounted by a delivery top for the liquid comprising a drop-counting end-piece protruding to the outside of the bottle and an anti-bacterial filtering membrane, 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 delivery top comprises an insert with a recessed body which contains a porous pad regulating the flow of liquid placed downstream of the reservoir and upstream of a chamber delimited downstream of the said membrane. At the base of this insert on the inner side of the bottle, longitudinal arches supporting a central pellet make star-shaped passageways radially guiding the air that enters the bottle after having passed through the porous pad.本發明有關一種具有點滴器輸送裝置並且用於封裝液體之瓶子，其包括一具有可彈性地變形的壁面之貯存器，藉由讓空氣進入該容器能使該壁面反向，並藉由一用於該液體之輸送頂部所蓋上，且包括一突出至該瓶子外面之液滴計數式末端件及一抗菌的過濾隔膜，該過濾隔膜被製成為局部地親水性及局部地厭水性，其係在該末端件之基底被置入橫越該液體與該空氣之路徑。該輸送頂部包括一具有凹陷式本體之插入件，該凹陷式本體包含一調節液體流動的多孔狀墊片，該墊片被放置在該貯存器之下游以及藉由該隔膜的下游所界定之腔室的上游。在此插入件之基底，於該瓶子之內部側面上，支撐一中心圓片之縱向弓形部分造成星形通道，其徑向地導引在已通過該多孔狀墊片之後進入該瓶子的空氣。
