PROBLEM TO BE SOLVED: To provide an unsealing mechanism in various kinds of a tubular liquid container, relating to an applicator for medical liquid, including a handle part equipped with a hollow tubular member, a tubular liquid container built in the tubular member, and an unsealing means of the liquid container, as well as an application part equipped with a fitting plate of an application pad being bonded to a lower end of the tubular member as an inclined cross section, and an application pad being fitted to the fitting plate.SOLUTION: A circumference part of a lower bottom surface or a diameter part of the lower bottom surface of a tubular liquid container is formed into easy-peel. A piston having a piston rod is inserted into an upper part of a tubular liquid container. The piston is pushed in by the piston rod so that a pressure is applied to a liquid in the tubular liquid container, for cleavage of the easy-peel, so that the liquid in the tubular liquid container is delivered to the application pad. An unsealing mechanism includes easy-peel open type, as well as a pull-out type, escape screw cap type, cut-up type, pin pull-out type, twist and cut type.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT【課題】中空の筒状部材と、該筒状部材に内蔵されている円筒状液体容器と、該液体容器の開封手段とを備えたハンドル部;及び、前記筒状部材の下端に傾斜断面となるように固着されている塗布パッドの取付板と、該取付板に付着された塗布パッドとを備えた塗布部;を有する医療用液体のアプリケータにおける、前記円筒状液体容器の種々の開封機構を提供すること。【解決手段】円筒状液体容器の下底面の円周部、又は下底面の直径部がイージーピールに形成され、円筒状液体容器の上部には、ピストンロッドを有するピストンが嵌合されており、前記ピストンロッドによりピストンを押し込み、円筒状液体容器内の液体に圧力をかけることにより前記イージーピールを開裂させ、円筒状液体容器内の液体を塗布パッドに送出するイージーピールオープンタイプの他、引き抜きタイプ、脱ネジキャップタイプ、切裂きタイプ、ピン引き抜きタイプ、捻切りタイプの開封機構を備える。【選択図】 図3
