Apparatus and method for manufacturing a plastics container

Abstract From the Canadian patent

The invention provides a method and apparatus for manufacturing rounded containers having inner and outer mating wall parts of plastics with a printed paper segment between said parts. The method comprises locating an outer wall part at a paper insert station in alignment with the smaller open end of a tubular tapered guide, feeding a printed paper segment through the tapered guide,where it is progressively shaped to correspond with the container but is given slightly smaller dimensions,and into said outer wall part whereupon, the resilience of the segment due to bending causes it to expand into contact with the interior of said outer wall part. An inner wall part is pressed into the outer …
