The outer container body defines a first chamber and includes a first reactant. The inner container body defines a second chamber. The inner container body is disposed within the first chamber and hold a substance to be heated or cooled. The reactant vessel is provided within the first chamber underneath the inner container body. The reactant vessel contains a second reactant capable of reacting with the first reactant to generate an exothermic or endothermic reaction. The breakable barrier covers the reactant vessel.
