Abstract
Abstract A method of coating an edible food container by applying a moisture-resistant fat coating to the interior of the container by introducing the coating into the container and forcing the coating up the inside surface by rapidly rotating the container and/or coating. The resulting container has a more uniform and continuous film coating.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
112 words
A method of processing an edible food container for use with a food product which comprises applying a moisture-resistant, barrier coating composition of a food grade fat material to at least the interior surface of the edible food container in an amount sufficient to produce a continuous, uniform film of said barrier coating composition on said surface, said barrier coating composition being applied by introducing an effective amount of said coating composition into the edible food container and then forcing the coating composition up the inside surface of the container by imparting relative motion to the container and coating composition to effect a rotational motion of the coating composition within the container.
Claim 2
Independent Claim
112 words
A method of processing an edible food container for use with a food product which comprises applying a moisture-resistant, barrier coating composition of a food grade fat material to at least the interior surface of the edible food container in an amount sufficient to produce a continuous, uniform film of said barrier coating composition on said surface, said barrier coating composition being applied by introducing an effective amount of said coating composition into the edible food container and then forcing the coating composition up the inside surface of the container by imparting relative motion to the container and coating composition to effect a rotational motion of the coating composition within the container.
Claim 3
Dependent Claim
25 words
The method of claim 1 wherein the edible food container is rotated to force the barrier coating composition up the inside surface of the container.
Claim 4
Dependent Claim
27 words
The method of claim 1 wherein the barrier coating composition within the container is rotated to force the coating composition up the inside surface of the container.
Claim 5
Dependent Claim
26 words
The method of claim 2 or 3 wherein the excess coating composition escapes from the top of the container and is recovered and recycled for reuse.
Claim 6
Dependent Claim
35 words
The method of claim 1 wherein the barrier coating composition is heated to the melting point of the fat and the application of the barrier coating composition to the container is conducted at ambient temperature.
Claim 7
Dependent Claim
16 words
The method of claim 5 wherein the coated containers are cooled subsequent to the coating operation.
Claim 8
Dependent Claim
17 words
The method of claim 1 wherein the food grade fat material includes modified fats and mixtures thereof.
Claim 9
Dependent Claim
58 words
The method of claim 7 wherein the food grade fat material is selected from the group consisting of an acetylated monoglyceride having a melting point of 99° to 115° F., a hydrogenated cotton seed oil having a melting point of 136° to 144° F. and a hydrogenated vegetable fat having a melting point of 115° to 119° F.
Claim 10
Dependent Claim
14 words
The method of claim 1 wherein the fat material contains a flavor producing additive.
Claim 11
Dependent Claim
13 words
The method of claim 9 wherein the flavor is rye, onion or garlic.
Claim 12
Dependent Claim
16 words
The method of claim 9 wherein the flavor is orange, lemon, grapefruit, grape, banana, or maple.
Claim 13
Dependent Claim
46 words
The method of claim 3, wherein a mandril extends into coating composition disposed within the edible food container and the barrier coating composition within the container is rotated by the rotation of the mandril to force the coating composition up the inside surface of the container.
Claim 14
Dependent Claim
51 words
An edible food container produced by the process of claim 1, said edible food container being provided with a moisture resistant barrier coating composition having a substantially uniform thickness on at least the internal surface thereof, said coating composition comprising a food grade fat, food grade modified fats or mixtures thereof.
