Abstract
This relates to an annular seam between two tubular body portions. The seam is particularly adapted for joining open ends of two cup members to form a container. The seam incorporates a hem on one of the members with the hem facilitating the application of the adhesive required to bond the cup members together while at the same time permitting the same adhesive to engage raw edges of the cup members in sealing relation.
