  • Bottom profile for a seamless container body
    Patent number: 4646930
    Abstract: A bottom profile for a cylindrical two-piece drawn steel can is configured during manufacture so that the resultant bottom profile shape includes areas of highly worked metal positioned to assume processing stresses. A bottom wall bead is included and has a prescribed cross-sectional configuration to provide maximum abuse resistance and to be functionally and operationally interchangeable in the packing and processing line with traditional three-piece containers. Moreover, the prescribed bead configuration works to improve stacking crush resistance by work hardening the metal adjacent the corner between the bottom and wall of the can.

  • Method for deep drawing thin metal stock into containers and thereafter coating each container
    Patent number: 4637117
    Abstract: A lubricant is provided to help in drawing containers such as cans from tinplate or coated tin free steel and to assist the metal forming process during drawing. The lubricant is formulated to permit a post spray without removal of the lubricant thereby eliminating washing and drying the container before post spraying. Post spray coatings are solvent or water based and are necessary to protect the container from the harmful effects of the material carried within the container and in turn to prevent contamination of the product by its container. A method of lubricating a metal to be deeply drawn into a sanitary can is explained and includes leaving the lubricant on the can during interior post coating operations.

  • Coated metal container and method of making the same
    Patent number: 4507339
    Abstract: A metal container comprising a seamless body and an end wall integral therewith and having on at least its interior surface a protective coating which is the reaction product of a citric acid ester utilized as a lubricant in forming the container and an after-applied synthetic resin.

  • Container shape
    Patent number: 4264017
    Abstract: A bottom profile for a cylindrical two-piece drawn steel can is configured during manufacture so that the resultant shape may subsequently be altered by pushing downward at the outer profile ring adjacent the periphery with a simple cylindrical tool, thereby achieving a finished container with the desired configuration to be functionally and operationally interchangeable in a packing and processing line with traditional three-piece containers.
