  • Tubular container with a heat seal having non-symmetrical inner and outer beads
    Patent number: 6881286
    Abstract: A sealed composite container for products is provided having a paperboard body ply with a liner ply adhered on the inner surface thereof. One end of the container is rolled outwardly to form a rim and exposing the inner surface of the liner ply, which comprises a heat sealable composition. A lid for the container, also having a layer of heat sealable composition, is placed adjacent to the exposed heat sealable composition of the container liner and heat sealed thereto. The heat seal has both an inner and an outer bead formed on either side of the heat sealed area, wherein the inner bead comprises a larger amount of the heat seal compositions than the outer bead. A method and apparatus for forming the heat seal is also provided.

  • Container having a preshaped end closure
    Patent number: 6829874
    Abstract: A tubular container for vacuum packaging products is provided according to the present invention that includes an overcap secured to at least one of the opposed ends of a tubular container that defines a bias member for biasing a membrane-type flexible lid inwardly towards products contained within the tubular container before a vacuum is applied. The flexible lid is maintained in a biased shape until the bias member is removed. As such, the flexible lid is sufficiently restrained during the vacuum packaging process, thus preventing the breakage of products located adjacent the flexible lid.
