ABSTRACT:
Two-piece containers having a one-piece tubular body and base and a cover molded onto the body are formed from a continuous web of thermoplastic supporting material by means of an apparatus which includes tube forming, cover molding, container filling and container base sealing stations. The web of material is initially formed into a strand of partially assembled tubular container bodies having fold impressions for the base and then severed into separate tubular bodies for further processing, filling and sealing.
