Abstract
Abstract This specification discloses a laminated pad intended to be used in the cooking of foods, particularly meat. The pad is a laminated construction comprising a bottom layer of metallic foil, a comparatively thick intermediate layer of an absorbent material such as cellulose, and a top layer of metallic foil. The top and bottom layers initially are of greater extent than the absorbent layer so that protruding marginal portions may be folded about the side edges and joined to provide a complete envelop about the absorbent layer. The top layer is formed with a multiplicity of small openings through which grease or other food secretions drain to be absorbed the intermediate layer. In a modification a plurality of top foil layers are provided so that one may be peeled off to present a new layer after each usage. A method of fabricating such a pad is also disclosed in which the foil layers are integrally joined at one side so that after the absorbent pad is positioned they are folded and the remaining side edges joined.

Total Claims: 4
Claim 1
Independent Claim
145 words
In a laminated cooking pad, an intermediate layer of absorbent material presenting top, bottom, and side surfaces, imperforate layers of a metallic foil covering said bottom and side surfaces, and a top layer of metallic foil having a plurality of diamond-shaped embossments penetrating into the absorbent layer, and openings formed at the corners of said diamond-shaped embossments, said openings being of a diameter ranging from 0.0185 inch to 0.0625 inch and being present in the amount of from five to 64 per square inch whereby an increased flashpoint is caused by the absorbent material preventing the grease from being exposed to an ignition source and the absorbent material is effective until it becomes completely saturated with grease and the liquid grease is exposed to the ignition source, at that point the presence of the perforated upper layer is effective in increasing the resistance to flashing.

Claim 3
Dependent Claim
205 words
In a laminated cooking pad, an intermediate layer of absorbent material presenting top, bottom, and side surfaces, imperforate layers of a metallic foil covering said bottom and side surfaces, and at least two top layers of metallic foil, each having a plurality of openings permitting drainage of grease from a piece of meat thereon to said absorbent pad, the openings in one of said top layers being in alignment with the openings in the adjacent top layer, the marginal portion of each top layer having a depending lip overlying the corresponding lip of the next adjacent top layer with the exception of the innermost top layer the lips of which overlie the edges of the bottom layer, said openings being of a diameter ranging from 0.0185 inch to 0.0625 inch and being present in the amount of from five to 64 per square inch whereby an increased flashpoint is caused by the absorbent material preventing the grease from being exposed to an ignition source and the absorbent material is effective until it becomes completely saturated with grease and the liquid grease is exposed to the ignition source, at that point the presence of the perforated upper layers is effective in increasing the resistance to flashing.
