发明名称 METHOD FOR PRODUCING TUBULAR PLASTIC CONTAINERS
摘要 A method for producing thermoplastic tubular containers having a tubular wall section, open neck, and integral sealed bottom where a thermoplastic disc, is sealed to the inner wall of the tubular wall section, and the disc, while in a moldable state, is formed into a bottom wall by application of either a vacuum to the exterior surface of the disc or a fluid pressure to the interior of the tubular wall section, or both, to mold the disc in a mold cavity to a desired shape. A supporting sleeve surrounds the tubular wall section during application of the fluid pressure. Thermoplastic containers can be formed from a single thermoplastic material or from laminates, such as a laminate material containing an oxygen impermeable layer.
