Abstract: A can body (40) drawn from a tinplate to comprise an end wall (41) and an integral side wall (42) which extends from the periphery of the end wall to a terminal portion defining a mouth, has a margin (48) of coating material, such as expoxy phenolic lacquer, applied only to an upper portion of the interior surface of the side wall (42) leaving the interior tin surface of the rest of the side wall and end wall (41) exposed. The side wall may be wall ironed from selected grade of tinplate. The advantages arising are protection of cold worked side wall material and control of the ammount of tin available to be picked up by a product in the can.Various methods are described for making the cans such as deep drawing and alternatively wall ironing.

Abstract: In a method in which containers, such as cylindrical metal cans, are printed by means of dye diffusion transfer, from a flexible paper carrier which is heated to shrink the carrier into intimate contact with a dye receptive coating on the surface of the container, and to effect dye transfer, the carrier has a weight of 35-110 grams per square meter, an equilibrium moisture content of 2-15% when exposed to air with a relative humidity of 50%, and is applied to the container so that the direction of grain of the paper is parallel to the axis of symmetry passing through the center of the base of the container.

Abstract: Metal containers, such as cans, are printed when empty by means of dye diffusion transfer, the dyes being first printed on to a paper web which is cut into individual carriers. Each carrier is secured, somewhat in the manner of a label, to a container by a water-soluble adhesive so that, upon being heated to effect dye transfer, the carrier comes into intimate contact with a suitably receptive coating, pre-applied to the container, solely by virtue of its own shrinkage. The carrier and adhesive are subsequently removed by water spray.
