  • Patent number: 5958549
    Abstract: A resilient prestressed honeycomb structure comprises a honeycomb core having a plurality of abutting partition walls forming opposed hollow-cell faces defining planar surfaces and a face sheet secured to one of the planar surfaces. The partition walls or the face sheet is air-permeable, and at least one of the hollow-cell faces has been compressively deformed laterally along its planar surface to provide a substantially continuous cushioned face portion. The cushioned face portion is sufficiently resilient to cushion substantially all surfaces of a body in contact therewith. When one of the hollow-cell faces is compressively deformed, the air-permeable partition walls or the air-permeable face sheet allows air to flow therethrough.

  • Patent number: 5948457
    Abstract: A modified atmosphere packaging method creates a modified atmosphere in a package including an inner package and an outer package. The inner package is composed at least partially of a polymeric material substantially permeable to oxygen, while the outer package is composed of a polymeric material substantially impermeable to oxygen. After a food product such as raw meat is placed within the inner package, the inner package is flushed with a desired mixture of gases to substantially remove oxygen from the inner package. The flushed inner package is then sealed and inserted into the outer package without sealing the outer package. Next, the outer package is flushed with the desired mixture of gases to substantially remove oxygen from the outer package. After flushing the outer package, the outer package is sealed. An oxygen scavenger is provided in the package to substantially absorb any residual oxygen within the package.

  • Patent number: 5904643
    Abstract: A process and apparatus for forming three-dimensional containers from a continuous flat web of paper, coated paper, paper board, or laminated paper board ("paper") in which the paper is first scored to define the shape of the container and, thereafter, the scored stock is simultaneously cut and formed into a container. Containers so produced have improved uniformity. The apparatus is less expensive and easier to operate than conventional equipment, and it is easier to change from one style of tray to another. The apparatus also makes possible tray styles which could not be made with machines which cut and transfer paper blanks to a separate forming station.
