## Abstract

A product having an internal substance protected by a rugged exterior shell is disclosed. The internal substance is reactive with the exterior shell but is separated therefrom by a coating on an interior surface of the external shell so that the product can be stored for a long period of time without the internal substance reacting with the exterior shell. The coating is meltable so that, when desired, the product may be heated (e.g. immersed in hot water or exposed to heat) in order to melt the coating so that the internal substance can react with the external shell so that the internal substance can excrete out of the exterior shell.

## Claims

### Claim 1

A method of producing casing which is dissolvable in water, the method comprising the steps of:
forming first and second ribbons of a material for forming a food grade exterior layer, each of the first and second ribbons defining an interior surface and an exterior surface;
forming a food grade inner protective layer on the interior surfaces of the first and second ribbons;
guiding the first and second ribbons between first and second rollers;
after forming the food grade inner protective layer on the interior surfaces of the first and second ribbons, disposing a consumable substance between the first and second ribbons, the consumable substance being separated from the first and second ribbons with the food grade inner protective layer;
forming a plurality of casings with the first and second rollers to encapsulate the consumable substance within the casing.

### Claim 2 (depends on 1)

The method of claim 1 wherein the consumable substance is a solid.

### Claim 3 (depends on 1)

The method of claim 1 wherein the step of forming the food grade inner protective layer is accomplished by spraying a food grade paraffin in liquid form on the interior surfaces of the first and second ribbons.

### Claim 4 (depends on 1)

The method of claim 1 wherein step of forming the first and second ribbons comprises the step of forming the first and second ribbons to be between about 0.2 mm and about 3 mm.

### Claim 5 (depends on 1)

The method of claim 1 wherein the step of disposing the consumable substance includes the step of injecting a material having a viscosity between about 5,000 cP and about 10,000 cP.
