Abstract
Abstract A disposable cooking pan is provided which is formed from a single sheet of thin gauge metal. The pan includes a bottom panel which is delimited by a continuous upwardly and outwardly extending wall panel. Extending laterally outwardly from the upper edge portion of the wall panel is a continuous rim. The rim includes a planar outwardly extending inner section and a bead-like outer section which encompasses a multilateral area including the inner section. Relatively spaced, enlarged areas are formed in the rim inner section and are disposed adjacent portions of the rim outer section defining corners in the multilateral areas. Elongated strengthening ribs are provided in the enlarged areas of the rim inner section and extend from adjacent the rim outer section to the upper edge portion of the wall panel.

Claim 1
Independent Claim
203 words
A disposable cooking pan formed from a single sheet of thin gauge metal, comprising a bottom panel; a continuous wall panel encompassing said bottom panel and extending upwardly and outwardly from the periphery thereof; and a continuous rim encompassing an upper edge portion of said wall panel and projecting laterally outwardly therefrom; said rim including a substantially planar inner section and a bead-like outer section, the outer section encompassing a multilateral area including the inner section, said inner section having relatively spaced enlarged areas disposed adjacent corner-forming portions of said outer section, said enlarged areas being provided with elongated strengthening ribs extending towards the upper edge portion of said wall panel; wherein each strengthening rib formed in the enlarged areas of the rim inner section includes a first segment declining at a first angle from adjacent the rim outer section towards the wall panel and terminating a predetermined distance from the wall panel, and a second segment declining at a second angle from the termination of said first segment to the wall panel, said second angle being greater than said first angle, said second segment terminating at the wall panel at a location substantially below the upper edge portion of the wall panel.
Claim 2
Dependent Claim
203 words
A disposable cooking pan formed from a single sheet of thin gauge metal, comprising a bottom panel; a continuous wall panel encompassing said bottom panel and extending upwardly and outwardly from the periphery thereof; and a continuous rim encompassing an upper edge portion of said wall panel and projecting laterally outwardly therefrom; said rim including a substantially planar inner section and a bead-like outer section, the outer section encompassing a multilateral area including the inner section, said inner section having relatively spaced enlarged areas disposed adjacent corner-forming portions of said outer section, said enlarged areas being provided with elongated strengthening ribs extending towards the upper edge portion of said wall panel; wherein each strengthening rib formed in the enlarged areas of the rim inner section includes a first segment declining at a first angle from adjacent the rim outer section towards the wall panel and terminating a predetermined distance from the wall panel, and a second segment declining at a second angle from the termination of said first segment to the wall panel, said second angle being greater than said first angle, said second segment terminating at the wall panel at a location substantially below the upper edge portion of the wall panel.
Claim 3
Dependent Claim
32 words
The pan of claim 1 wherein the juncture of the first and second segments of each strengthening rib in the enlarged areas of the rim inner section form a transversely extending ridge.
Claim 4
Dependent Claim
60 words
The pan of claim 1 wherein the wall panel includes opposed side wall sections, opposed end wall sections, and corner wall sections interconnecting adjoining side and end wall sections, all of said wall sections being of substantially uniform thickness and coacting to form a multilateral area of a different shape than the multilateral area encompassed by the bead-like outer section.
