  • Patent number: 4880581
    Abstract: An apparatus and method for aseptic, particle-free production of articles. A shroud is placed around at least a portion of the device which produces the articles to substantially isolate that portion from the external environment. The device for producing the articles and the shroud are sterilized and the air inside the shroud is filtered and sterilized. A laminar or other type of flow of filtered, sterilized air is imparted through the shroud over the articles being produced. A secondary shroud encloses the corridor or work area adjacent the shroud and device which produces the articles. The corridor and secondary shroud are sterilized, and sterilized and filtered air is continually introduced therein. The articles therefore are particle-free and sterilized for further use. The apparatus and method can be used for any component production process employing high temperatures and/or pressures, including, but not limited to, blow molding, injection molding, and production of semiconductor electronic components.

  • Patent number: 4539172
    Abstract: A method is disclosed for forming, filling and hermetically sealing a blowmolded container having a sterile integral inner dispensing outlet, all in a single sterile operation. The method is directed toward establishing a preferably hermetic seal between the inner dispensing outlet and the container neck, by establishing the seal early in the blowmolding cycle. This is accomplished by mounting the dispensing outlet-defining tubular member about a unique fluid supply mandrel. The supply mandrel thereby also serves as a check and the tubular member of the to-be-formed container serves as a tool in blowmolding. The dispensing outlet/container neck seal is thus formed before the blowmolding step.
