As the liquid medicine is made to drip the container by the pushing doing directly by light power, at the time of container restoration, the fluid leak from opening of the pressure valve is prevented. The container itself which has the flexibiility and restoration characteristic in order to accommodate the liquid medicine it communicates to 1 and container itself 1, the pressure where opening of the section circle where container itself 1 receives pushing pressure and when becoming deformed, in liquid medicine passage P in order to make the liquid medicine spit out which is accommodated in container itself 1 is locked is arranged, when seeing the point 4e from liquid medicine emission direction, plug component 4d inside plug component 4d and liquid medicine passage P where section becomes circle compared to is installed on liquid medicine emission direction downstream side, contacts the point 4e of plug component 4d was formedValve, pressure valve 5 inside 5 and liquid medicine passage P compared to it is provided on liquid medicine emission direction downstream side, pressure valve 5 it has with the energization component 7,7a in order energization to do for the direction of opposite to liquid medicine emission direction by this touching to the around section 5b of opening of pressure valve 5.容器を軽い力で直接押することにより薬液を滴下させるとともに、容器復元時には、圧力弁の開口からの液漏れを防止する。薬液を収容するための可撓性、復元性のある容器本体1と、容器本体1に連通し、容器本体1が押圧を受けて変形したときに、容器本体1に収容されている薬液を吐出させるための薬液通路Pの中に固定配置され、その先端部4eを薬液吐出方向から見たときの断面が円形になっている栓部材4dと、薬液通路P内の、栓部材4dよりも薬液吐出方向下流側に設置され、栓部材4dの先端部4eに接触する断面円形の開口が形成された圧力弁5と、薬液通路P内の、圧力弁5よりも薬液吐出方向下流側に設けられ、圧力弁5の開口の周囲部5bに当接することにより、圧力弁5を薬液吐出方向と逆の方向に付勢するための付勢部材7,7aとを備えている。
