1. A method of aseptic, particle-free production of interiors and exteriors of articles, to avoid the need for chemical or irradiation treatment of the articles, and to provide aseptic articles which are prepared for further processing, comprising the steps of:

  • creating an aseptic environment within a clean room;

    shrouding at least a portion of an article producing means of a production machine to substantially segregate the portion of the article producing means from the clean room but retaining some communication with the clean room;

    substantially isolating the portion of the article producing means which is shrouded from any external environment and from the clean room;

    sterilizing the interior of the clean room, the portion of the article producing means within the shroud, the interior of the shroud, and any surfaces of the shroud inside and communicating with the clean room;

    filtering and sterilizing any air enclosed by the clean room and the shroud; and

    imparting a flow of filtered, sterilized air through the clean room and into the shroud, over and around the articles being produced on the portion of the article producing means within the shroud, and out of the shroud, so that the articles produced will be aseptic interiorally and exteriorally and ready for further processing.
