Abstract
In a method of producing a metallic container by subjecting a metallic material having an organic resin coating to single-staged or multiple-staged drawing, uniformly coating a lubricant on the surface of the organic resin coating of the metallic material and draw-forming the coated material, according to the present invention, a high lubricating property is obtained at the time of drawing by using a small amount of a saturated hydrocarbon as the lubricant, and by simply heating the formed can, a major portion of the lubricant can be removed and the degreasing and washing steps or the subsequent drying step essential in the conventional method, can be omitted, with the result that the printability or the flavor-retaining property can be markedly improved, and consumption of water resource and energy resource can be reduced and a high effect of preventing environmental pollution can be attained.
