Claim 1

A composite container for packaging, comprising: a substantially rigid fiber tube; a cup, of a plastic material suitable for containing a fluent pressurized material, said cup having a cylindrical wall with an integrally formed hemispherical bottom, the exterior surface of said wall being contiguous with the interior surface of the fiber tube, said cup being firmly supported by the fiber tube; an annular plastic cup flange connected to the top edge of the cup wall, the innermost bottom surface of said flange being contiguous with the top edge surface of the fiber tube, the remaining portion of said flange extending upwardly above the top edge surface of the fiber tube and partially beyond the exterior surface of the fiber tube; a metal end closure having a countersink wall snugly seated within the upper end of the cup, the exterior surface of aid countersink wall being contiguous with the interior surface of the upper wall of the cup; an annular metal closure flange connected to the top edge of the countersink wall of the metal end closure and overlying the cup flange, the marginal inner bottom surface of the closure flange being contiguous with the innermost top surface of the cup flange, the bottom surface of the remaining portion of the closure flange being contiguous with the remaining portion of the cup flange which extends upwardly above the top edge surface of the fiber tube and partially beyond the exterior surface of the fiber tube; and a double seam formed by the respective remaining contiguous portions of the closure and cup flanges, said double seam being offset from, and positioned entirely upwardly above, the top edge surface of the fiber tube.
