Abstract
Self-heating containers comprise a reaction chamber and a heating chamber. The heating chamber is sized to contain a substance to be heated. The reaction chamber contains reactants which, when contacted, exothermically react. The reaction chamber is divided into a first compartment and a second compartment with a barrier therebetween. The barrier comprises a first barrier portion and a second barrier portion. A centering element can be used to facilitate alignment of the barrier portions.
