An eyedropper (2) is provided for administering a predetermined volume of liquid onto the surface of an eye (57). The eyedropper (2) includes a body (104) having a nozzle (27) in fluid communication with the internal cavity (114) of the reservoir body (18). Projecting from an inner surface (110) of the reservoir body (18) are a first projecting portion (125A) having a first contact surface (26A) and a second projecting portion (25B) having a second contact surface (26B). The first contact surface (26A) and the second contact surface (26B) are disposed opposite from one another and are spaced apart from one another. In use, the first and second contact surfaces (26a) limit the displacement volume of the internal cavity (114) when the eyedropper (2) is squeezed thereby limiting the volume of liquid expelled from the nozzle (27).本發明提供一種滴眼器(2),其用於投與預定體積之液體至眼睛(57)之表面上。該滴眼器(2)包括主體(104),其具有與儲集體(18)之內腔(114)流體連通之噴嘴(27)。自該儲集體(18)之內表面(110)突出之部分為具有第一接觸面(26A)之第一突出部分(125A)及具有第二接觸面(26B)之第二突出部分(25B)。該第一接觸面(26A)及該第二接觸面(26B)係彼此相對安置且彼此隔開。使用時,當擠壓該滴眼器(2)時,該第一接觸面(26a)及該第二接觸面限制該內腔(114)之位移體積,藉此限制自該噴嘴(27)排出之液體的體積。2‧‧‧滴眼器3-3‧‧‧線4‧‧‧主體4-4‧‧‧線6‧‧‧第一支腿8‧‧‧第二支腿14‧‧‧第一支腳16‧‧‧第二支腳18‧‧‧儲集體20‧‧‧外表面25A‧‧‧第一突出部分27‧‧‧噴嘴28‧‧‧第一端面36‧‧‧第二端面52‧‧‧儲集器部分56‧‧‧液體投與部分58‧‧‧帽蓋60‧‧‧開口62‧‧‧尖端66‧‧‧凹口68‧‧‧帽蓋70‧‧‧止滴件72‧‧‧螺紋74‧‧‧凸緣75‧‧‧噴嘴部分80‧‧‧凸起狀突出物a‧‧‧第一軸線b‧‧‧第二軸線α‧‧‧角β‧‧‧角γ‧‧‧角
