ABSTRACT OF THE DISCLOSURE There has been developed end units for cans of the easy opening type wherein end panels of the end units are provided with patterns of holes to facilitate the dis- pensing of a product. The holes are closed by means of strips, preferably formed of plastics material, overlying the holes and being bonded to the metal of the end units adjacent the holes. It is preferred that the bonding of the strips be effected by heat. A special induction heater has been constructed which induces into the metal of the area to where the strips are to be bonded electrical energy which results in the heating of the metal. The heater is particularly constructed so as to compensate for the holes in the metal of the end units and thus a uniform heating of the metal over the area to which the strip is to be applied can be effected.
