Abstract:
1. A container comprising: an outer container body defining a first chamber comprising a first reactant; an inner container body defining a second chamber adapted to hold a substance to be heated or cooled, wherein the inner container body is disposed within the first chamber and secured directly to the outer container via an attaching lip; a reactant vessel provided within the first chamber adjacent to the inner container body, wherein the reactant vessel contains a second reactant capable of reacting with the first reactant to generate an exothermic or endothermic reaction; a breakable barrier covering the reactant vessel; and a breaking device comprising an annular disc having a central aperture disposed within outside of the reactant vessel so that an outside perimeter of the annular disc is in contact with an inner wall of the outer container and disposed the first chamber between the inner container body and the reactant vessel and entirely above the breakable barrier, wherein the breaking device comprises a plurality of protrusions fixed to the annular disc extending radially outward and downward to a central tip and evenly arranged in the central aperture throughout the breaking device to efficiently break the barrier and quickly release the first reactant to mix and react with the second reactant and wherein the breaking device further comprises a plurality of openings located on the annular disc to allow the first reactant to quickly mix with the second reactant, wherein at least some of the openings are positioned between adjacent protrusions.
