Zusammenfassung:A stackable shallow container such as a plate is integrally formed of thermoplastic sheet material with a continuous closed outline figure stacking fin consisting of tightly folded together adjacent continuous wall regions depending axially from the bottom wall, side wall or rim of the container. One method and apparatus for forming such a container from sheet material comprises relatively axially movable concentric tool parts spaced radially the thickness of the sheet material for folding the container wall to provide the fin.
