Instant self-heating containers include a combinable reactant and activator used to generate an exothermic reaction for heating contents of the container. One instant self-heating container includes a target container, a pierceable activator container and a reaction chamber. Piercing the activator container causes activator to combine with the reactant and cause an exothermic reaction that heats the target container. The container may be used as depilatory wax dispenser. Another instant self-heating container includes an outer housing containing a contents pouch and a reactant, and capped by a lid having an activator chamber. Rupturing the activator chamber allows activator to combine with the reactant in an exothermic reaction to heat the contents pouch. Another instant self-heating container includes a flexible outer tube containing contents to be heated, a flexible reaction vessel, and a frangible activator vessel. Bending the outer tube causes the activator vessel to rupture and cause an exothermic reaction.

1. A self-heating container, comprising: a first shell configured to receive contents;a second shell external to and nested with the first shell, the second shell comprising a reaction chamber comprising a reactant therein; andan activator container comprising an activator, wherein the activator container and the first shell each have walls that prevent the activator from penetrating the first shell; andwherein the activator container is configured to be opened to release the activator into the reaction chamber; andwherein, when the activator container is opened, the activator contacts the reactant and forms an exothermic reaction that radiates heat between the first shell and the second shell to transfer heat to all walls of the first shell. 2. The self-heating container according to claim 1, further comprising a contents cover sealing the contents to be received in the first shell, the contents cover having at least a portion that is openable to provide access to the first shell. 3. The self-heating container according to claim 2, further comprising an activator cover sealing the activator inside the activator container. 4. The self-heating container according to claim 3, wherein the contents cover and the activator cover are integral parts of a single container cover. 5. The self-heating container according to claim 4, further comprising a target container disposed inside in the first shell, wherein the target container comprises the contents to be received in the first shell, wherein the first shell further comprises a flat flange circumscribing the target container and the activator container, and wherein the single container cover is a peel-back cover adhered to the flat flange of the first shell. 6. The self-heating container according to claim 1, further comprising a target container disposed inside in the first shell, wherein the target container comprises the contents to be received in the first shell. 7. The self-heating container according to claim 6, wherein the first shell further comprises a spout configured to facilitate drinking the contents from the target container. 8. The self-heating container according to claim 6, wherein the target container has a bottom surface comprising at least one protrusion that forms a concentric ring. 9. The self-heating container according to claim 6, wherein the target container has a bottom with at least one protrusion extending upwardly into the target container. 10. The self-heating container according to claim 1, further comprising a piercer disposed in the activator container, wherein the piercer is configured to open the activator container and is a cross shaped member having a pointed lower end and an upper end adjacent to an upper end of the activator container. 11. The self-heating container according to claim 10, wherein the piercer is a rigid plastic spear. 12. The self-heating container according to claim 1, further comprising an aromatherapeutic substance disposed in the reaction chamber or activator container, wherein when the activator contacts the reactant, aromatherapeutic gases are released from the self-heating container. 13. The self-heating container according to claim 1, wherein the exothermic gel sequesters the activator and restricts the activator from leaking out of the reaction chamber. 14. The self-heating container according to claim 1, wherein the first shell and the second shell are bonded together. 15. The self heating container according to claim 1, wherein the activator container further comprises a lower surface, and wherein the second shell is constructed from a material stronger than the lower surface of the activator container. 16. The self-heating container according to claim 1, further comprising a pull string operatively connected to the activator container, wherein the pull string is configured to be pulled from outside the self-heating container, and wherein pulling the pull string causes the activator container to be opened to release the activator into the reaction chamber.
