Abstract:
1. An assembly for generating a change in temperature comprising: a housing having a cylindrical body with opposing ends, wherein at least one of said housing ends is outwardly domed and inwardly flexible, wherein said housing is not integrally attached to another housing; at least two reactive components inside said housing; at least one frangible member separating said at least two reactive components from each other; a device disposed in said housing for breaking the frangible member and thereby enabling the components to react with each other, wherein inward flexing of said domed end causes said device to break said frangible member; a food or beverage container including a receptacle having a wall with a movable portion opposing said domed end, and means for transmitting movement of said movable portion to said domed end, wherein the assembly generates a temperature change within said receptacle; and a liquid inside said receptacle and in contact with the assembly.
