-8- CONTAINER AND METHOD OF MAKING THE SAME ABSTRACT OF THE DISCLOSURE This relates to a bottom construction for a composite container wherein the container body is of a composite construction such as a wound paper tube having a plastic material liner. The bottom construction in- cludes a generally cup-shaped closure element formed from a plastic material sheet which is molded in situ within the bottom end of the tubular body with the plastic material being heated to a molding temperature with the temperature being such that the plastic material of the closure will self-bond to the plastic material of the liner. The closure is of a generally hat-shaped configura- tion and includes a central cup portion which is tele- scoped within the end of the tubular body and which is then provided with a reinforcing disk, after which the extreme end portion of the tubular body is curled or rolled radially inwardly to abut against the underside of the reinforcing disk to complete the bottom construc- tion.
