Abstract
Products and methods of increasing the Rigidity and Rim Stiffness of disposable containers are provided. The containers have an outer flange portion extending outwardly with a brim portion sloping downwardly defining a declivity angle α with respect to a horizontal generally parallel to the bottom portion and generally include an outward turn at the periphery of the container. A preferred method of improving rigidity includes press-forming: (i) a brim transition portion adjoining the downwardly sloping brim portion of the container and (ii) an outwardly extending annular evert portion adjoining the brim transition portion extending outwardly at an eversion angle β of at least about 25 degrees with respect to the downwardly sloping brim portion of the flange.
