Abstract
A reusable heat or cold chemical therapy pack (10) is provided that has two pairs of compartments (12a and 14a; 12b and 14b). One pair of compartments (12a, 14a) is located on one side of the pack (10) and the other pair (12b, 14b) is located on the opposite side. Each pair of compartments is separated by a rupturable seam (16a, 16b). Each compartment contains a chemical reactant. One compartment in each pair (12a, 12b) is filled with a liquid reactant, and the other compartment in each pair (14a, 14b) is filled with solid beads (15) of reactant material. The compartments proximate those of the opposite pair contain different reactant materials. Therefore, since the solid reactant material (15) will not transfer pressure to the rupturable seam (16a, 16b), only one side of the pack (10) can be activated at a time by pressing on the respective compartment (12a, 12b) containing the liquid reactant.
