A mechanism and method for filling containers within a sterile chamber under aseptic conditions includes a vertically disposed nozzle (48) which forms an extension of the sterile chamber and which is arranged to have its lower outlet end inserted into an open container to be filled and which is provided with valve closure element (51) which is opened when the nozzle is at its lowermost position and which remains open during filling of the container which is accompanied by upward movement of the nozzle and of the closure element while maintained in open position so as to prevent splashing together with a drip proof seal (49, 52, and 53) for preventing dripping following closure of the valve means. A measuring cylinder (10) and associated piston (9) are mechanically interrelated with the nozzle so that charging movement of the piston forces a measured quantity of flowable material into the nozzle for discharge therefrom while the nozzle is moved upwardly and once the upward movement of the nozzle is completed upward movement of the measuring piston commences followed by independently controlled downward movement of the nozzle and opening of the nozzle closure means. According to one feature of the invention the flowable material is isolated from atmosphere by suitable barrier cavities containing sterile inert gas under slight pressure above atmospheric pressure and defined in part by rolling seals which isolate the moving elements from atmoshpere.

Apparatus for aseptically filling a container (C) disposed within a sterile walled enclosure structure (3) pressurized with a sterile inert gas, said apparatus comprising a nozzle (48) movably mounted in an aperture formed in a wall of said enclosing structure and located above said container, a housing (45) secured to said wall in fluid tight relation and disposed about said nozzle, a rolling seal (91) secured in fluid tight relation to the interior of said housing and to the exterior of said nozzle and forming a fluid tight cavity therebetween, means (97) for supplying inert sterile gas under pressure somewhat above atmospheric pressure to said cavity, and aseptic means (56-58) for supplying sterile flowable material to the interior of said nozzle.
