Abstract
A nestable, dual-ovenable cooking pan (10) made of thin, thermoformed plastic sheet material has an interlocking beam and skin structure including a peripheral frame (24) in its floor (12) and vertical horizontal ribs (28, 30) in its walls (14, 16). This structure cooperates with integral handles (32) in a top flange (20) to enhance strength and rigidity. The handles have uniform or non-uniform undulations (34, 36) which, in addition to providing rigidity, increase the effective thickness of the handles and allow the pan to be comfortably picked up and carried when hot. The handles cool relatively quickly. The undulations give the handles a purchase and feel similar to those of thicker handles of ceramic permanent cookware. The plastic sheet material is preferably nucleated CPET.
