Abstract
Abstract A microwave-reflective first container, designed to preclude microwave exposure of the sides and bottom and limit exposure to the top of a shelled, raw egg contained therein, is covered by a microwave-permeable lid and nested within a microwave-permeable second container so that the bottom and lower sides of said first container are in physical contact with a microwave-lossy liquid contained therein. Also, disclosed are (1) temperature monitoring, (2) a spoon shape to said first container's bottom, (3) restricting the ability of said first container to rotate and (4) methods of using said apparatus to soft and hard cook raw, shelled eggs from both their prefrozen and room temperature states.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
149 words
A utensil to cook an egg in a microwave oven which comprises: a microwave-reflective, heat-conductive, open-mouthed first container with inner side walls and a floor which define a chamber and where said inner walls and floor are constructed so that, when said egg is contained in said chamber, the yoke of said egg, which is denser than the white of said egg, will sink through said egg white by gravity until said yolk is microwave shielded from beneath by contacting said first container's floor and lower side walls and said yolk rests on said floor beneath said egg white, a microwave-permeable second container disposed in a spaced relationship with said first container to that, at least, a portion of the heat-conductive outer surface of said first container will be in physical contact with a microwave-lossy liquid when said liquid is outside said first container and inside said second container.
Claim 2
Dependent Claim
149 words
A utensil to cook an egg in a microwave oven which comprises: a microwave-reflective, heat-conductive, open-mouthed first container with inner side walls and a floor which define a chamber and where said inner walls and floor are constructed so that, when said egg is contained in said chamber, the yoke of said egg, which is denser than the white of said egg, will sink through said egg white by gravity until said yolk is microwave shielded from beneath by contacting said first container's floor and lower side walls and said yolk rests on said floor beneath said egg white, a microwave-permeable second container disposed in a spaced relationship with said first container to that, at least, a portion of the heat-conductive outer surface of said first container will be in physical contact with a microwave-lossy liquid when said liquid is outside said first container and inside said second container.
Claim 3
Dependent Claim
20 words
A utensil to cook an egg, according to claim 1, which includes: a microwave-permeable, light-transparent cover for said first container.
Claim 4
Dependent Claim
21 words
A utensil to cook and egg, according to claim 1, which includes: means to measure the temperature of said microwave-lossy liquid.
Claim 5
Dependent Claim
31 words
A utensil to cook an egg, according to claim 1, which includes: means to measure the temperature of the yolk of said egg when said egg is in said first container.
Claim 6
Dependent Claim
31 words
A utensil to cook an egg, according to claim 1, which includes: means to prevent said first container, when contained in said second container, from rotating independent from said second container.
Claim 7
Dependent Claim
50 words
A utensil to cook an egg, according to claim 1, which includes: where the egg-contacting-surface of said first container is smooth and round so that said smooth-round surface facilitates the removal of said egg when a spoon with a rounded bowl is used to remove said egg from said utensil.
Claim 8
Dependent Claim
37 words
A utensil designed to cook an egg, according to claim 1, which includes: indicia on the wall surface of said second container to effect measurement of said microwave-lossy liquid when said liquid is inside said second container.
Claim 9
Dependent Claim
132 words
A utensil to cook an egg in a microwave oven which comprises: a narrow-mouthed, tapered, heat-conductive, microwave-reflective first container whose side walls and floor define an open-mouthed chamber and whose lower side walls and floor are constructed to contain, when said egg is contained within said first container, just the yolk of said egg when said yolk, which is denser than the white of said egg, sinks by gravity beneath said white and rests on said floor beneath said egg white, and a microwave-permeable second container disposed in a spaced relationship with said first container so that, at least, a portion of the heat-conductive outer surface of said first container will be in physical contact with a microwave-lossy liquid when said liquid is outside said first container and inside said second container.
Claim 10
Dependent Claim
132 words
A utensil to cook an egg in a microwave oven which comprises: a narrow-mouthed, tapered, heat-conductive, microwave-reflective first container whose side walls and floor define an open-mouthed chamber and whose lower side walls and floor are constructed to contain, when said egg is contained within said first container, just the yolk of said egg when said yolk, which is denser than the white of said egg, sinks by gravity beneath said white and rests on said floor beneath said egg white, and a microwave-permeable second container disposed in a spaced relationship with said first container so that, at least, a portion of the heat-conductive outer surface of said first container will be in physical contact with a microwave-lossy liquid when said liquid is outside said first container and inside said second container.
Claim 11
Dependent Claim
28 words
A utensil to cook an egg in a microwave oven, according to claim 8 which includes: where said open-mouthed container, when filled, will hold four ounces of water.
