Patent No. 2102208A: Process Of Packaging Beer In Open Top Metal Containers

Today in 1937, US Patent 2102208 A was issued, an invention of Alfred L. Kronquest, assigned to the Continental Can Co., for his “Process of Packaging Beer in Open Top Metal Containers.” There’s no Abstract, although in the description it includes this summary:

This invention relates to new and useful processes for the pasteurizing of the beer.

The present invention has to do with a method of making and treating a container so as to provide a suitable coating covering the entire inner surface of the metal container so as to prevent the beer from contacting with the metal at any time. It is well known that when metal sheets are coated with an enamel that has no clouding effect upon the beer, the bending or drawing of the sheet to form the ends and to form the body seams, is likely to fracture the enamel coating temperature necessary to heat the sealed container so as to expose the metal there beneath. Even if the can body and the bottom end thereof is coated with enamel, the shaping of the parts is likely to fracture the enamel coating and render the container thus formed unsuitable for 5 the packaging of beer.
