Abstract
A rigid sheet metal substrate can body (50) and end closure (92) provides dependable tamper-evident and abuse-resistant packaging for shipment and long shelf-life storage without freezing; and, in addition, provides for direct heating in the can body after opening, including microwave heating, for serving and/or eating directly from such disposable container. The can body is shaped by draw processing with diminishing cross sectional areas in proceeding height-wise from open end (61) to closed bottom wall (56).
