With the method of filling up the plastic make container (2) by the liquid substance of sterilization and the container, as for the container (2) when sterilization filling up device division is received, in order the cover structure where it can decide closed sterile environment simultaneously (S) to enter, supply route (P) paralleling, continuing, it moves. As, the container (2) route (P) 1st section (T) paralleling, the device which is located (1) is sterilized with the 1st part (6), after that, weight fills up with the liquid substance it continues, 1st section (T) route after (P) 2nd section (TR) parallels and the closed seal it is done the plug of advance sterilization end/by the cover the device which is located (1) the 2nd part (12) in.< Selective figure >Figure 1プラスチック製容器(2)の殺菌ならびに容器の液体物質による充填の方法により、容器(2)は殺菌・充填装置区画が収納されると同時に閉鎖無菌環境が定められる覆い構造(S)に入るように供給経路(P)に沿って連続して移動する。容器(2)は経路(P)の第1区間(T)に沿って位置する装置(1)の第1部分(6)で殺菌され、その後、液体物質で重量充填されるとともに引き続き、第1区間(T)後の経路(P)の第2区間(TR)に沿って位置する装置(1)の第2部分(12)において事前殺菌済の栓/蓋により閉封される。【選択図】図1
