Abstract
Lids made of aluminum alloys or ferrous material such as tin plate or tin free steel having at least one stamped out pouring hole and, if desired, at least one hole for air have hot sealed pull-off strips covering the said holes. On the inner side of the lids the region around the holes is pre-treated with an adhesive primer and then coated with a plastisol layer thus providing the cut edges at the holes with protection against attack by the contents of the can.
