Method for forming a seam release strip composite container

A method for forming a composite container for fluent material in the liquid or semi-frozen state comprising the steps of:

• (a) providing a spirally wound, vertically arranged cylindrical body member including concentrically arranged fibrous body wall and fluid impervious inner liner layers;
• (b) flaring the upper end portion of said body member radially outwardly approximately 15 to 30 degrees relative to the vertical to form a terminating flared portion having a length of approximately one-sixteenth of an inch;
• (c) arranging a seam release strip circumferentially about at least the flared portion of said body member;
• (d) providing an end closure member for closing the upper end of said body member, said closure member comprising:
• (1) a circular central panel portion;
• (2) an annular chuck wall portion extending upwardly from said central panel portion;
• and
• (3) an annular connecting flange portion extending radially outwardly from the upper end of said chuck wall portion;
• (e) applying an annular bead of sealing material adjacent the junction between said flange and chuck wall portions of said end closure member;
• (f) positioning said end closure member relative to the upper end of said body member to place said central panel portion within and extending transversely across the upper end of said body member and to place said chuck wall portion adjacent the outwardly flared portion of said body member, said connecting flange and chuck wall portions cooperating with the inner surfaces of said body member flared portion and the adjacent portion of said body member, respectively, to define an annular space, whereby said annular bead of sealing material is contained in at least the upper portion of said annular space;
• and
• (g) crimping said connecting flange portion inwardly into connecting engagement with said body member and said seam release strip without causing substantial deformation of said body member, thereby causing said mass of sealing material to seal the annular space between the end closure member and the body member, whereby upon pulling of the seam release strip, the end closure member is released for removal from said body member.
