Abstract
Abstract A food package is provided wherein the accommodated food product, while remaining in the package, may be heated or cooked in a microwave oven. The food product has at least one predetermined portion thereof which requires enhanced heat while the product is being heated or cooked in the oven. The food package includes a container formed of heat resistant material which is pervious to the microwaves. A surface of the container is provided with an area which is in proximity to the predetermined portion of the food product requiring the enhanced heat. A metallized ink, consisting of metal particles suspended in an ink-like substance, is deposited on the surface area of the container. Thus, when the metallized ink is exposed to the generated microwaves, the required enhanced heat is produced in the vicinity of the surface area.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
128 words
A food package for heating or cooking a food product accommodated therein in a microwave oven, the accommodated food product having at least one predetermined portion thereof requiring enhanced heat during heating or cooking of the product, said package comprising a container for the food product formed of a heat resistant material pervious to the microwaves generated within the oven, said container having a surface area in proximity to the predetermined portion of the accommodated food product, said surface area having deposited thereon a metallized ink, the latter having a predetermined amount of metal particles suspended in an ink-like substance, whereby when said metallized ink is exposed to generated microwaves, the surface area produces the required enhanced heat for the one predetermined portion of the accommodated food product.
Claim 2
Dependent Claim
128 words
A food package for heating or cooking a food product accommodated therein in a microwave oven, the accommodated food product having at least one predetermined portion thereof requiring enhanced heat during heating or cooking of the product, said package comprising a container for the food product formed of a heat resistant material pervious to the microwaves generated within the oven, said container having a surface area in proximity to the predetermined portion of the accommodated food product, said surface area having deposited thereon a metallized ink, the latter having a predetermined amount of metal particles suspended in an ink-like substance, whereby when said metallized ink is exposed to generated microwaves, the surface area produces the required enhanced heat for the one predetermined portion of the accommodated food product.
Claim 3
Dependent Claim
54 words
The food package of claim 1 wherein the accommodated food product has a plurality of predetermined portions requiring enhanced heat during heating or cooking of the food product in the microwave oven, said container having a corresponding number of surface areas on which is deposited the metallized ink for effecting the required enhanced heat.
Claim 4
Dependent Claim
64 words
The food package of claim 2 wherein the metallized ink deposited on certain surface areas of the container has an amount of suspended metal particles which is different from the amount of suspended metal particles in the metallized ink deposited on other surface areas thereby effecting enhanced heat of different temperatures when the food product is subjected to the microwaves generated within the oven.
Claim 5
Dependent Claim
33 words
The food package of claim 1 wherein an exposed surface of the deposited metallized ink is coated with a material having a non-stick surface characteristic for the purpose of direct food contact protection.
Claim 6
Dependent Claim
15 words
The food package of claim 1 wherein the container is formed of a paperboard material.
Claim 7
Dependent Claim
28 words
The food package of claim 1 wherein the food product is initially enclosed within the container and remains therein while being heated or cooked within the microwave oven.
Claim 8
Dependent Claim
20 words
The food package of claim 1 wherein the metallized ink is deposited on the container surface in a predetermined pattern.
Claim 9
Dependent Claim
19 words
The food package of claim 1 wherein the metallized ink is deposited over an entire surface of the container.
Claim 10
Dependent Claim
23 words
The food package of claim 1 wherein the metallized ink is deposited on a predetermined area of an interior surface of the container.
Claim 11
Dependent Claim
23 words
The food package of claim 1 wherein the metallized ink is deposited on a predetermined area of an exterior surface of the container.
Claim 12
Dependent Claim
18 words
The food package of claim 9 or 10 wherein the metallized ink is printed onto the predetermined area.
Claim 13
Dependent Claim
32 words
The food package of claim 1 wherein the container has a tray-like configuration and the surface area on which the metallized ink is deposited subtends and supportingly engages the accommodated food product.
Claim 14
Dependent Claim
103 words
A disposable container for accommodating a food product having at least one predetermined portion requiring enhanced heat when the food product is heated or cooked within a microwave oven, said container being formed of a heat resistant material pervious to microwaves and having a surface area on which is deposited a metallized ink, the latter having a predetermined amount of metal particles suspended in an ink-like substance, said surface area adapted to be in proximity to the predetermined portion of the food product and provide the required enhanced heat therefor when the food product is subjected to the microwaves generated within the oven.
Claim 15
Dependent Claim
103 words
A disposable container for accommodating a food product having at least one predetermined portion requiring enhanced heat when the food product is heated or cooked within a microwave oven, said container being formed of a heat resistant material pervious to microwaves and having a surface area on which is deposited a metallized ink, the latter having a predetermined amount of metal particles suspended in an ink-like substance, said surface area adapted to be in proximity to the predetermined portion of the food product and provide the required enhanced heat therefor when the food product is subjected to the microwaves generated within the oven.
Claim 16
Dependent Claim
58 words
The disposable container of claim 13 wherein a plurality of surface areas are provided on which is deposited the metallized ink, each surface area adapted to be in proximity to a corresponding predetermined portion of the accommodated food product which requires enhanced heat when the food product is being heated or cooked by microwaves generated in the oven.
