Abstract

Various embodiments of the present invention feature a self-heating or self-cooling container that is simple in design. The container includes an outer container body, an inner container body, a reactant vessel, a breakable barrier, and a breaking device. 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. The breaking device is disposed within the first chamber between the inner container body and the reactant vessel. The breaking device is capable of breaking the barrier to release the second reactant into the first chamber to mix and react with the first reactant when activated.
