Composite end closure member for composite containers

摘要

An improved composite container is disclosed in which a composite end closure member having a horizontal generally disk-shaped central portion and an annular flange portion is bonded to one end of a tubular cylindrical composite body member, preferably by the use of radio frequency or dielectric energy. Preferably, the body member end portion is reversely inwardly curled to define an upwardly extending curled portion the free extremity of which is contiguous with the end member, thereby to structurally reinforce the container and to more securely hold the end member in place.
