Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
78 words
An article of manufacture suitable for use in the microwave cooking of foodstuffs, which comprises a dielectric substrate and an array of discrete dots of electroconductive material of microwave-reflecting thickness supported on said dielectric substrate and having a transverse dimension of about 0.0001 to about 0.1 inch and spaced apart one from another by a distance of about 0.0001 to about 0.1 inch sufficient to effect guidance of an enhanced proportion of incident microwave energy through said substrate.
Claim 2
Dependent Claim
78 words
An article of manufacture suitable for use in the microwave cooking of foodstuffs, which comprises a dielectric substrate and an array of discrete dots of electroconductive material of microwave-reflecting thickness supported on said dielectric substrate and having a transverse dimension of about 0.0001 to about 0.1 inch and spaced apart one from another by a distance of about 0.0001 to about 0.1 inch sufficient to effect guidance of an enhanced proportion of incident microwave energy through said substrate.
Claim 3
Dependent Claim
17 words
The article of manufacture of claim 1 wherein said dielectric substrate is a flexible polymeric film substrate.
Claim 4
Dependent Claim
18 words
The article of manufacture of claim 2 wherein said polymeric film substrate is laminated to paper or paperboard.
Claim 5
Dependent Claim
15 words
The article of manufacture of claim 2 wherein said electroconductive material is an electro-conductive metal.
Claim 6
Dependent Claim
23 words
The article of manufacture of claim 4 wherein said electroconductive metal is aluminum having a thickness of about 0.0001 to about 0.01 inch.
Claim 7
Dependent Claim
17 words
The article of manufacture of claim 5 wherein said aluminum has a thickness of approximately 0.00035 inch.
Claim 8
Dependent Claim
35 words
The article of manufacture of claim 1, 2, 3, 4, 5 or 6 wherein said arrangement of small dots of electroconductive material is provided in the form of a substantially uniform array on said substrate.
Claim 9
Dependent Claim
21 words
The article of manufacture of claim 1, 2, 3, 4, 5 or 6 formed by selective demetallization of metallized polymeric film.
