ABSTRACT:
A flat planar lid for ovenable containers is described which is uniquely shaped to permit the lid to be manually secured to a flanged ovenable container thereby effectively closing and sealing the flanged container without the need to use automatic sealing equipment. The planar lid is shaped to provide a longitudinal tab overlapping each longitudinal edge of the container, a transverse tab overlapping each transverse edge of the container, and a corner tab overlapping each corner of the container. These tabs of the lid are tucked over the container flange and adhesively bonded to the underlying surface thereof. Venting is provided to permit a mechanism for venting internal steam to the atmosphere when the container and its contents are heated. The corner tabs have a lesser outboard reach than the outboard reach of either the longitudinal or transverse tabs to provide a smooth and substantially flat adhesive bond with the underflange surface.
