  • Patent number: 6117505
    Abstract: A sterilizable flexible pouch package includes a non-woven barrier web, a perforated plastic intermediate web, and an imperforate plastic upper web. Line heat seals bonding the webs from a cavity into which a sterilizing steam may enter after passing through the barrier and intermediate webs. The line heat seal bonding the upper and intermediate webs is of the delamination failure type. An access opening is provided for insertion of an object to be sterilized into the cavity after which the access opening is sealed, enclosing the object in the cavity. After sterilizing, the package is opened by peeling apart the upper web from the intermediate web which causes a delamination failure of the line heat seal. Preferred materials enable steam sterilization at temperature of 270.degree. F.

  • Patent number: 6112772
    Abstract: A system with reduced electrostatic discharge including woven fabric configured into a flexible container and having sufficient electrical resistivity to allow discharges of energy from the fabric of below about one-hundred nanocoulombs when the fabric is charged to more than about negative ten thousand volts. The flexible fabric container with a reduced potential for incendiary discharge may further include quasi-conductive fibers or a combination of quasi-conductive fibers and an antistatic coating. The quasi-conductive fibers further may be woven into the fabric. The present invention also discloses a method for reducing electrostatic discharge in ungrounded type flexible fabric container systems by providing a flexible fabric container made from woven fabric and adjusting the electric resistivity of the woven fabric to allow the flow of electricity through the fabric at a rate allowing discharges at below about one-hundred nanocoulombs when the fabric is charged at more than about negative ten kilovolts.

  • Patent number: 5679449
    Abstract: A system with reduced electrostatic discharge including woven fabric configured into a flexible container and having sufficient electrical resistivity to allow discharges of energy from the fabric of below about one-hundred nanocoulombs when the fabric is charged to more than about negative ten thousand volts. The flexible fabric container with a reduced potential for incendiary discharge may further include quasi-conductive fibers or a combination of quasi-conductive fibers and an antistatic coating. The quasi-conductive fibers further may be woven into the fabric. The present invention also discloses a method for reducing electrostatic discharge in ungrounded type flexible fabric container systems by providing a flexible fabric container made from woven fabric and adjusting the electric resistivity of the woven fabric to allow the flow of electricity through the fabric at a rate allowing discharges at below about one-hundred nanocoulombs when the fabric is charged at more than about negative ten kilovolts.

  • Patent number: 5659933
    Abstract: Containers are described for retention of human or animal remains for extended periods. The bags are constructed of laminated materials and sealed, which prevents the escape of noxious or odorous decomposition gases or harmful decomposition fluids into the ambient surroundings. The invention also provides for infusion or extraction of gases to retard the decomposition of the contained remains. The container is constructed of flexible multilayer laminated walls forming an interior chamber for accommodation of remains, and after the remains are emplaced the container's opening is sealed. The multilayer laminate includes at least two layers of polymeric sheet material with a metal foil layer between them, although use of more complex polymer/metal laminates is also described. The polymeric layer materials include polyolefin, nylon or polyvinyl sheet materials and the metal foils are normally aluminum foil.
