摘要： Containers of synthetic plastic material having an outwardly extending flange about at least a portion of their periphery are subjected to an abrading operation along the outer edge of the flange and then to a brushing operation along the surface of the flange adjacent to the outer edge. To avoid contamination of the interior of the container by the abraded and other plastic particles, desirably air or other gas is caused to flow outwardly across the surfaces of the flange during the abrading and brushing steps.
