Abstract
Abstract In packing a sterile filling material under aseptic conditions, a pre-fabricated container is arranged in a holder device which is arranged on a conveyor belt which latter is translatable through a tunnel wherein a sterile atmosphere is maintained by a sterilizing electronic spray. In this tunnel and in the presence of this sterile atmosphere the filling and closing of the container is carried out.
