Abstract

See full text

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.
