摘要:
The invention relates to a method for manufacturing a packing container from a seamless tubular blank of plastic material having a wall thickness greater than the wall thickness of the packing container to be produced therefrom. One end of the tubular blank is sealed and an annular edge ferrule is joined to the other end. The tube is heated until softened and then caused to expand in a mold to a predetermined shape.
