    摘要: An improved end seam construction for composite containers used in the packaging of hard to hold materials, such as materials under vacuum or pressure. The composite tubular body wall member includes at least one fibrous layer to the inner wall surface of which is bonded by a thermoplastic adhesive a metal liner layer that projects axially at at least one end a given distance beyond the fibrous layer. The end of the fibrous layer is deformed radially outwardly to define a funnel-shaped flange about which the projecting metal liner layer is deformed and compressed. The length of the projecting metal liner layer is such that when the metal-lined flange portion is connected by a rolled seam with the flange, the metal liner layer is compressed into surface-tosurface engagement with at least one surface of the curl portion of the metal end. In order to position a sealing compound layer solely in the space between the rolled flange portion and the chuck wall and seaming panel portions of the metal end, an annular layer of the sealing compound is placed on the metal end, prior to connection with the composite body wall, from a point high on the chuck wall to a point on the seaming panel opposite the curl overhang.
