First Claim
1. A multi-use hot or cold chemical pack, comprising:
- a first compartment for holding a first substance having a first breakable wall;
a second compartment for holding a second substance having a second breakable wall;
a third compartment interposed between the first compartment and the second compartment having a perimeter including the first breakable wall and the second breakable wall;
a fourth compartment for holding a third substance having a third breakable wall;
a fifth compartment for holding a fourth substance having a fourth breakable wall; and
a sixth compartment interposed between the fourth compartment and the fifth compartment having a perimeter including the third breakable wall and the fourth breakable wall;
wherein the first compartment is proximal to the fourth compartment and the second compartment is proximal to the fifth compartment.

Abstract
The invention relates to a multi-compartment bag which provides for the separation of two substances until their desired intermixing. A specific application of this multi-compartment bag is for hot or cold chemical packs. The substances in the multi-compartment bag are separated by two breakable walls and a third compartment which together act as a barrier to migration of one substance into the second substance, which would reduce the shelf life and efficiency of the hot or cold chemical pack. The present invention'"'"'s use of two breakable walls and a compartment, empty or containing an inert substance, separating two reactive substances, provides a longer shelf life, a high efficiency, more reliability and improved ease of operation.

9. A multi-use hot or cold chemical pack, comprising:
-
a first sheet, a second sheet and a third sheet, wherein the first sheet, the second sheet and the third sheet are sealed together to form a first internal compartment and a second internal compartment; a first breakable wall, a second breakable wall, a third breakable wall and a fourth breakable wall; wherein the first breakable wall and the second breakable wall are arranged in the first internal compartment and are sealed to the first sheet and the second sheet so as to form a first compartment for holding a first substance, a second compartment for holding a second substance, and a third compartment interposed between the first and the second compartment; wherein the third breakable wall and the fourth breakable wall are arranged in the second internal compartment and are sealed to the second sheet and the third sheet so as to form a fourth compartment for holding a third substance, a fifth compartment for holding a fourth substance, and a sixth compartment interposed between the fourth compartment and the fifth compartment; wherein the first compartment is proximal to the fourth compartment and the second compartment is proximal to the fifth compartment. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
