The drop bottle construction that one kind can quantify output includes: the soft body that can be pressurized, the spray head of detachable-type sealed to soft body bottleneck and connects the structure for conveying set to spray head. Spray head top has spout, and bottom surface, which is run through, through-hole. Structure for conveying is provided sequentially by the first delivery pipe, extraction raffinate storing body, the flow path formed with the second delivery pipe. First delivery pipe one end is connected to extraction raffinate storing body, and another end is extended downwardly close to body bottom. Second delivery pipe at least has front end and end； The through-hole that its front end passes through spray head bottom surface is connected to the liquid storage space of the spray head, and end is then connected to the extraction raffinate storeroom in the extraction raffinate storing body. When body is pressurized, liquid will be pushed and be sequentially directed to spray head along flow path, contained in the liquid storage space of what spray head to predetermined volume Hou, quantitative dropping liquid is exported by spout.一種可定量輸出之滴瓶構造包括：可受壓之軟質瓶身、可拆卸式密封至軟質瓶身瓶口之噴頭、以及接設至噴頭之輸送結構。噴頭頂端具有噴口，底面貫穿有通孔。輸送結構提供依序由第一輸送管、餘液貯存體、與第二輸送管所形成之一流動路徑。第一輸送管一端連通餘液貯存體，另端向下延伸接近瓶身底部。第二輸送管至少具有前端與末端；其前端穿過噴頭底面之通孔與該噴頭之儲液空間連通，末端則與該餘液貯存體內之餘液貯存室連通。瓶身受壓時，將推擠液體依序沿流動路徑導引至噴頭，於噴頭之儲液空間內盛裝至預定體積後，由噴口輸出定量滴液。
