ABSTRACT:
A composite container for fluent materials in the liquid or semi-frozen state is disclosed, together with a method for making the same. The container includes a vertically arranged body member that is flared at its upper end, and an end closure member is provided including a circular central panel portion arranged within and extending across the upper end of the body member, annular chuck wall portion extending upwardly from the central panel portion adjacent the flared portion of the body member, and an annular connecting flange portion extending radially outwardly from the upper end of the chuck wall portion. The invention is characterized in that the connecting flange and chuck wall portions cooperate with the flared portion of the body member to define an annular space in which is arranged a resilient annular mass of sealing material. A seam release strip is arranged circumferentially about the outer surface of the upper portion of the body member, the connecting flange portion of the end closure being inwardly crimped into engagement with the body member and the seam release strip, thereby causing the mass of sealing material to be compressed to seal the annular space between the end closure member and the body member.
