Claim Text:
1. A self-heating object, comprising a pouch and an object to be heated, wherein the pouch comprises: an outer containment envelope having a periphery, the outer containment envelope comprising a first layer bonded to a second layer around the periphery of the outer containment envelope, the first layer having a slit; a sealed reactant compartment disposed inside the outer containment envelope, the sealed reactant compartment containing a first reactant; and at least two strips connected to the sealed reactant compartment, the at least two strips comprising a shear strip separated from an outer strip by a shear line, the shear strip and the outer strip each having a tip, wherein the outer strip is folded under the sealed reactant compartment with its tip anchored to the outer containment envelope, and wherein the shear strip extends away from the sealed reactant compartment and through the slit in the first layer of the outer containment envelope so that the tip of the shear strip is disposed outside the outer containment envelope; wherein pulling on the tip of the shear strip causes the shear line to lengthen until the sealed reactant compartment is shorn open and releases the first reactant into the outer containment envelope; and a second reactant compartment disposed inside the outer containment envelope adjacent the first sealed reactant compartment and containing a second reactant, the second reactant compartment further comprising: a permeable membrane, and a slit passing completely through the second reactant compartment; wherein the shear strip passes through the slit in the second reactant compartment.
