Abstract
Abstract A container tube comprises a tubular body and a prefabricated head secured upon one end of said body. The body may be formed by wrapping a plastic laminated foil sheet about a spindle, or it may be a length of extruded plastic tubing. The body has an inturned shoulder terminating in an edge that is embedded or otherwisw so disposed as to be protected against contact with the tube contents. The tube has a welded longitudinal seam wherein the edges are shielded from contact with the tube contents. Welding heat and pressure are provided by an induction coil mounted in a non-metallic member adapted to press the junctures to be fused against a high heat conductive support such as a metal spindle or block.
