摘要： Tubular containers comprising a tube of flexible packaging material joined to a closure member inserted in one end thereof. The closure member includes (1) an annular skirt to which the tube may be joined, and (2) a radially extending flange that extends around the circumference of the tube and projects beyond the exterior surface of the tube to form a portion that is adapted to be thermally reflowed around the end and exterior side portions of the tube to thereby conceal the junction of the tube and the closure member. Several methods for heat sealing the tube to the closure member are shown, including a heat seal between the exterior of the tube and a portion of the radially-extending flange. The tubular body may be made from a sheet of material folded into a tube with its edges joined together in a longitudinal seam, several forms having particular utility being shown herein. A method for the manufacture of tubular containers employing a closure member of the aforesaid construction includes the steps combining the tubular body and the closure member and thereafter reflowing the radially-extending flange about the outer surface of the tubular body through the application of heat.
