  • Patent number: 6065394
    Abstract: An improved, easily cleanable folding pan with a continuous cooking surface includes a pair of pan sections with generally planar cooking surfaces joined at the perimeter in side-by-side relationship by a pair of upstanding hinges. The hinges permit pivotal movement of the pan sections from a generally flat cooking position into a folded position for cleaning or storage. The fold margin of one of the pan sections slightly overlaps the fold margin of the other cooking surface, so that in the cooking position the pan presents a continuous cooking surface. The fold margin of one of the cooking surfaces may include a dependent lip for overlapping the fold margin of the other cooking surface when the pan is in the cooking position. A pair of opposed, upstanding handles may be coupled with the perimeter margin of the cooking surface. The perimeter margin of the pan section may be surmounted by an upstanding sidewall.
