  • Patent number: 5203491
    Abstract: A grease and oil resistant container useful for baking foods contained therein at elevated temperatures which includes a bottom wall and an upturned side wall extending the periphery of the bottom wall having an inner layer of parchment paper and an outer layer of ovenable paperboard. Preferably, the side wall includes a rim that extends outwardly from the side wall in an arcuate path. The rim may include a peripheral lip which extends downwardly from the rim. The container is formed by deep drawing a flat, circular blank. The blank includes an ovenable paperboard base layer and an inner, food compatible parchment layer. In addition, prior to press forming the blank, a plurality of radially extending pleats are formed circumferentially about the outer area of circular blank which will aid in the formation of a substantially rigid side wall.
