Selective coating characteristic tinplated steel cans

A one-piece sheet metal can body for special container packs requiring exposure of container contents to a tin surface while protecting remaining interior surfaces of the can body from contact with container contents, such special container pack can body having

• a bottom wall and unitary sidewall extending longitudinally in one direction from the bottom wall,
• the bottom wall and sidewall comprising flat rolled steel coated on interior surface of the bottom wall and sidewall with tin,
• the bottom wall sheet metal having a substantially uniform thickness gage between about 0.010 inch and 0.015 inch,
• the interior surface of the bottom wall having a substantially uniform tin coating between at least ten microinches in thickness and about 90 micro-inches in thickness,
• the sidewall being ironed and comprising over a major portion of its area a substantially thinner interior surface tin coating than the bottom wall, and further including
• a protective organic coating on substantially the entire interior surface of the sidewall to substantially eliminate contact of container contents with the sidewall, while
• the interior surface of the bottom wall provides an exposed tin coating for contact of such tin coated surface with container contents.
