Abstract
Abstract An aseptic packaging machine for forming, antiseptically treating, filling and sealing containers while protecting them with a clear air atmosphere after they have been antiseptically treated by a bactericide. The antiseptic treatment is accomplished by a fogging system to provide for total contact by the bactericide with the internal surfaces of the container and includes ease of removal of the residual bactericide after the treatment.
