CA 1176094

ABSTRACT An improved method is disclosed for forming a perforated or stamped out portion for eventual insertion of a drinking straw in a plastic container. Disadvantages of the prior commercial methods are avoided by first stamping out or perforating a moving strip of cardboard, then applying appropriate grid marks to the strip, then coating the strip with plastic, and, finally printing the coated strip and forming it into individual containers. The grid marks assist in controlling the operations.
