Microwave browning cookware

Claim 2

A cookware for use in a microwave over comprising: a body of a microwave non-absorbing material and a browning portion, said browing portion having a continuous metallic cooking surface which supports the browing portion on the body, a heat absorbing portion in contact with the bottom of the cooking surface and said heat absorbing portion being made from a material having a thermal conductivity greater than said cooking surface and provided in a relatively larger mass than said cooking surface, and a heating matrix of a microwave absorptive material in contact with the heat absorbing portion, the heating matrix adapted upon exposure to microwave radiation to create heat which is absorbed by the heat absorbing portion and retained, the heat retained by the heat absorbing portion being transferred to the cooking surface to cause a browning effect on food to be cooked.

Claim 3

A cookware as claimed in claim 1 wherein said cooking surface is made of a stainless steel material.

Claim 4

A cookware as claimed in claim 1 wherein said heat absorbing poriton is made of an aluminum material.

Claim 5

A cookware as claimed in claim 1 wherein said cooking surface is made of a stainless steel material and said heat absorbing portion is made of an aluminum material.

Claim 6

A cookware as claimed in claim 4 wherein said stainless steel cooking surface has a thickness of approximately 0.02 inches.

Claim 7

A cookware as claimed in claim 5 wherein said aluminum heat absorbing portion has a thickness between 0.08 and 0.11 inches, inclusive.

Claim 8

A cookware as claimed in claim 1 wherein said body is made of a thermostat polyester material.

Claim 9

A cookware as claimed in claim 1 wherein said browning portion is positioned within the body portion exposing only the cooking surface of the browning portion.

Claim 10

A cookware as claimed in claim 1 wherein said browning portion further comprises a channel surrounding the cooking surface and intergrally formed with said cooking surface.

Claim 11

A cookware as claimed in claim 1 wherein said browning portion further comprises a support contacting the body portion and positioning the browning portion within the body portion exposing only the cooking surface of the browning portion.

Claim 12

A cookware for use in microwave ovens comprising: a body defining an interior cavity open at its upper end and a rim around the cavity; a browning portion supported on the rim of the body, said browning portion including an integrally formed first portion of a relatively thin but rigid sheet of a stainless steel material and having a cooking surface, support arm, extension arm, and annular channel, the browning portion also including a heat absorbing body and a microwave absorptive matrix, the support arm of the first portion resting on the rim of the body, the extension arm extending into the cavity in the body from the support arm, the annular channel connecting the cooking surface to the extension arm, the channel formed adjacent to the cavity wall of the body, the cooking surface forming the bottom surface of the cookware within the body cavity, the heat absorbing body attached to the lower surface of the cooking surface between the annular channel and the heating matrix, the heat absorbing body made from a material having a thermal conductivity greater than stainless steel and provided in a relatively larger mass than the first portion, the heating matrix formed on the absorbing body opposite of its attachment to the first portion.

Claim 13

A cookware for use in microwave ovens comprising: a body defining an interior cavity open at its upper end and a rim around the cavity; a browning portion supported on the rim of the body, said browning portion including an integrally formed first portion of a relatively thin but rigid sheet of a stainless steel material and having a cooking surface, support arm, extension arm, and annular channel, the browning portion also including a heat absorbing body and a microwave absorptive matrix, the support arm of the first portion resting on the rim of the body, the extension arm extending into the cavity in the body from the support arm, the annular channel connecting the cooking surface to the extension arm, the channel formed adjacent to the cavity wall of the body, the cooking surface forming the bottom surface of the cookware within the body cavity, the heat absorbing body attached to the lower surface of the cooking surface between the annular channel and the heating matrix, the heat absorbing body made from a material having a thermal conductivity greater than stainless steel and provided in a relatively larger mass than the first portion, the heating matrix formed on the absorbing body opposite of its attachment to the first portion.

Claim 14

A cookware for browning the exterior surfaces of food prepared in a microwave oven comprising: a first portion having continuous metallic cooking or browning surface, a heat absorbing portion attached to the unexposed surface of the first portion, said heat absorbing portion having a higher thermal conductivity than the first portion and a thickness several times that of said cooking surface, and a heating portion in contact with the heat absorbing portion opposite its attachment to the first portion, the heating portion adapted to absorb microwave energy to create heat.

Claim 15

A cookware for browning the exterior surfaces of food prepared in a microwave oven comprising: a first portion having continuous metallic cooking or browning surface, a heat absorbing portion attached to the unexposed surface of the first portion, said heat absorbing portion having a higher thermal conductivity than the first portion and a thickness several times that of said cooking surface, and a heating portion in contact with the heat absorbing portion opposite its attachment to the first portion, the heating portion adapted to absorb microwave energy to create heat.

Claim 16

A cookware for use in microwave ovens comprising: a body formed from a microwave non-absorbing material, said body having a bottom wall, a side wall and a rim positioned around the upper periphery of the side wall; a continuous metallic pan having an upper cooking surface, a lower surface and a side wall, the pan adapted to be supported by the rim of the body with the side wall of the pan extending into the body towards the bottom wall, the side wall of the pan being spaced from the side wall of the body and the pan forming a cavity between its lower surface and the body bottom wall; a heat absorbing body fused to the lower surface of the metallic pan and maintained in the cavity between the lower surface and the body bottom wall, the heat absorbing body having a greater mass and a higher thermal conductivity than said metallic pan and a thickness several times that of said metallic pan, and a heating mtrix adapted to create heat when exposed to microwave radiation, the matrix attached to the lower surface of the heat absorbing body.

Claim 17

A cookware for use in microwave ovens comprising: a body formed from a microwave non-absorbing material, said body having a bottom wall, a side wall and a rim positioned around the upper periphery of the side wall; a continuous metallic pan having an upper cooking surface, a lower surface and a side wall, the pan adapted to be supported by the rim of the body with the side wall of the pan extending into the body towards the bottom wall, the side wall of the pan being spaced from the side wall of the body and the pan forming a cavity between its lower surface and the body bottom wall; a heat absorbing body fused to the lower surface of the metallic pan and maintained in the cavity between the lower surface and the body bottom wall, the heat absorbing body having a greater mass and a higher thermal conductivity than said metallic pan and a thickness several times that of said metallic pan, and a heating mtrix adapted to create heat when exposed to microwave radiation, the matrix attached to the lower surface of the heat absorbing body.
