Abstract

Abstract A dual-purpose baking pan assembly suitable for use in a conventional oven wherein the assembly as well as the food therein are exposed to a high-temperature atmosphere, and in a microwave oven wherein the atmosphere is close to ambient temperature and the assembly and the food are subjected to microwave energy. All components of the assembly are formed of a dielectric material unaffected by microwave energy and capable of withstanding high temperatures. The assembly is constituted by a circular base which fits into an annular groove formed in a cylindrical shell defined by a pair of complementary half-sections whose rear ends are hinged together by a removable pivot pin and whose front ends are joinable by a detachable clamp. Thus, after a food product is baked in the assembly, the shell thereof may be detached from the base to expose the food product without disrupting its structure.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 92 words
A pan assembly for a food product comprising: A. a circular base having a peripheral lip; B. a cylindrical shell formed by a pair of arcuate sections which are hinged together at one end, said shell having adjacent its bottom an inner groove to receive the lip of the base; and C. means at the other ends of the sections to clamp the sections together, whereby after the food product is baked or otherwise heated, the shell may be detached from the base to expose the baked product without disturbing its structure.
Claim 2
Dependent Claim 92 words
A pan assembly for a food product comprising: A. a circular base having a peripheral lip; B. a cylindrical shell formed by a pair of arcuate sections which are hinged together at one end, said shell having adjacent its bottom an inner groove to receive the lip of the base; and C. means at the other ends of the sections to clamp the sections together, whereby after the food product is baked or otherwise heated, the shell may be detached from the base to expose the baked product without disturbing its structure.
Claim 3
Dependent Claim 15 words
A pan assembly as set forth in claim 1, wherein said sections have straight sides.
Claim 4
Dependent Claim 35 words
An assembly as set forth in claim 1, wherein all components thereof are formed of dielectric heat-resistant material whereby the assembly may be used either in a high temperature oven or in a microwave oven.
Claim 5
Dependent Claim 15 words
An assembly as set forth in claim 3, wherein said material is a polyester resin.
Claim 6
Dependent Claim 38 words
An assembly as set forth in claim 1, wherein the bottom of the shell has a ring formation, and said base includes a circular platform below the lip that lies within the ring to create a leak-proof seal.
Claim 7
Dependent Claim 19 words
An assembly as set forth in claim 1, wherein said sections are hinged together by a removable pivot pin.
Claim 8
Dependent Claim 34 words
An assembly as set forth in claim 1, wherein an upper face of the base is indented in a repetitive diamond-like pattern and serves as a cutting board for the food product baked thereon.
Claim 9
Dependent Claim 39 words
An assembly as set forth in claim 1, wherein said clamping means is constituted by a clasp hinged to a post on one of said sections and having a cam section which engages a post in the other section.
Claim 10
Dependent Claim 15 words
An assembly as set forth in claim 8, wherein said clasp has a handle thereon.
