Can body with a sealing compound placed on a step or flange and method of forming such a can body

摘要

A can body is provided with a shelf or flange (17) onto which pliable material such as a lining compound (12) is deposited in fluid form. A closure (30) is placed onto the shelf (17) whilst the compound (12) is still in its fluid state. The closure (30) thus forms a depression in the compound (12), which then hardens into this shape to fix the closure (30) in position. The can body of the invention is particularly suited to use in the packaging of foods which are then processed in an overpressure retort.
