## Abstract

An improved disposable foil cooking sheet which is manufactured as a triputite laminate. The laminate comprises a generally flat foraminous impermeable foil upper layer, a central core of dry bibulous material and a generally flat imperforate lower layer. Several disposable foil cooking sheets may be connected in seriation and rolled into a roll.

## Claims

### Claim 1

A tripartite, laminate, generally flat, self-form-maintaining, thin, cooking, rectangular, sheet element comprising:
(A) a generally flat, foraminous, rectangular, upper layer composed of non-combustible, impermeable, malleable aluminum foil,
(B) a generally flat, continuous, rectangular, central core layer composed of a dry bibulous material capable of absorbing hot liquid fat, and
(C) a generally flat, rectangular, lower, imperforate layer composed of non-combustible, impermeable, malleable aluminum foil coextensive and in registry with the upper layer, whereby rendered fat from a fat-containing comestible being broiled in a broiling chamber while resting on said element will drain through the foramina in said upper foil layer, to be absorbed in said core layer, trapped by said lower foil layer and contained between said upper and lower foil layers, so that spattering of the rendered fat in the chamber will be reduced,
(D) said upper and lower layers extending peripherally beyond the boundaries of the core layer and being peripherally sealed together by continuous seams to form a peripheral margin having a thickness not in excess of 4 mils,
(E) the periphery of said tripartite element being sufficiently deformable to be manually bendable with great ease and to be pinched together at the corners of the rectangular element to form peripheral flanges on all edges of the cooking sheet, which flanges are self-form-maintaining so that the element can be formed into the shape of a shallow pan,
(F) the thickness of each of the foil layers being between 1/4 mils and 2 mils,
(G) the sizes of the foramina ranging between 1/64" and 1/8" across.

### Claim 2 (depends on 1)

A sheet element as set forth in claim 1, wherein the spacing of the foramina is 3 to 5 to the inch in orthogonal directions.

### Claim 3 (depends on 1)

A sheet element as set forth in claim 1, wherein the exterior surface of the upper layer is specular.

### Claim 4 (depends on 1)

A sheet element as set forth in claim 1, in which the upper layer is crinkled.

### Claim 5 (depends on 1)

A sheet element as set forth in claim 1, in which the foramina located in the vicinity of the center of the upper layer are larger than the foramina located in the vicinity of the periphery of the upper layer.

### Claim 6 (depends on 1)

A sheet element as set forth in claim 1, in which the sheet is one of a plurality of substantially identical broiling sheets, each connected seriatim to adjacent sheets by opposed border zones, adjacent border zones being separated by a weakened zone.

### Claim 7 (depends on 6)

The plurality of sheet elements of claim 6 in which the sheet elements are rolled up into a cylindrical roll.
