    摘要: Container bags for intravenous solution of one-piece, blow-molded construction typically have a fill port or tube and at least an administration port in one end of the container bag. A method, an apparatus and an article of manufacture are provided where a fill port or tube on a polyolefin or other plastic container bag is sealed into a dome shape where the solid wall, dome-shaped material closing the port or tube effects the seal. The method provides for sealing the open end of a thermoplastic tube or port by using respectively hot and cold dies. Resistance of the tube or port to forming a seal at adjoining interfaces is overcome by rotating at least one of the dies. Disruption and mixing of the plastic at the interface or closure line is accomplished, forming a substantially homogenous mass which seals the port opening.

    摘要: Any of various features of a workpiece are forged by a common set of tools. The feature is incrementally forged as the tool set is moved to successive forging locations on the surface of the workpiece. One of the tools is used to plasticize and extrude a portion of the workpiece while one or more of the other tools are used to form dams that contain and shape the extruded portions.
