Abstract
A temperature changing container includes a plurality of walls joined to form an enclosure which seals contents of the enclosure within the walls. One of the walls includes a depression extending into the enclosure. Upon activation, chemicals at least partially disposed within the depression change temperature.
Claims21
A self-heating container comprising;
- a cylindrical metal side wall;
- a top, can end joined to the metal side wall with a joint;
- a metal, bottom can end joined to the metal side wall to form an enclosure having an interior, the metal bottom can end including a depression extending into the interior;
- wherein the depression has a depth and a radius, wherein the depth is less than the radius;
- and
- a heating element including a canister located at least partially within the depression, the canister having chemicals hermetically sealed therein and an activation structure configured to permit a user to cause the chemicals to react and increase the temperature of the interior of the container, wherein the canister is sized relative to the depression of the metal bottom can end such that the canister is held within the depression via an interference fit formed between an outer surface of the canister and a surface of the depression;
- wherein the canister is a cylindrical metal canister including a metal upper wall, a cylindrical metal side wall and a metal lower wall, wherein a diameter of the lower wall of the canister is less than a diameter of the bottom can end, wherein the depression is a cylindrical depression and wherein the interference fit is formed between an outer surface of the cylindrical metal side wall of the canister and a cylindrical surface of the depression;
- wherein the metal bottom can end and the metal lower wall of the canister are coplanar.

A temperature changing container comprising:
- a plurality of walls joined to form an enclosure which hermetically seals a contents of the enclosure within the walls, wherein one of the walls includes a depression extending into the contents of the enclosure, wherein the depression has a depth and a radius, wherein the depth is less than the radius;
- and
- a temperature changing element including a canister located at least partially within the depression, the canister having an upper end, a lower end, a sidewall joining the upper end and the lower end, and chemicals hermetically sealed therein and an activation structure configured to permit a user to cause the chemicals to change state to change the temperature of the canister, wherein an outermost diameter of the lower end of the canister is less than an outermost diameter of the wall including the depression;
- wherein the canister is a cylindrical metal canister including a metal upper wall, a cylindrical metal sidewall and a metal lower wall, wherein the depression is a cylindrical depression and wherein an interference fit is formed between an outer surface of the cylindrical metal sidewall of the canister and a cylindrical surface of the depression;
- wherein the wall including the depression and the metal lower wall of the canister are coplanar.

A container comprising:
- a plurality of walls joined to form an enclosure which hermetically seals a contents of the enclosure within the walls, wherein one of the walls includes a depression extending into the contents of the enclosure, wherein the depression has a depth and a radius, wherein the depth is less than the radius;
- and
- a metal heating canister located at least partially within the depression, the heating canister having chemicals hermetically sealed therein and an activation structure configured to permit a user to cause the chemicals to change state to change the temperature of the heating canister, wherein the heating canister is sized relative to the depression such that the heating canister is held within the depression via an interference fit;
- wherein the heating canister is a cylindrical metal canister including a metal upper wall, a cylindrical metal sidewall and a metal lower wall, wherein a diameter of the lower wall of the canister is less than a diameter of the wall including the depression, wherein the interference fit is formed between an outer surface of the cylindrical metal sidewall of the canister and a cylindrical surface of the depression;
- wherein the wall including the depression and the metal lower wall of the canister are coplanar.
2 more elements
A can end for a heated container comprising:
- a periphery configured to be coupled to a side wall of a can creating a hermetic seal between the side wall and the can end;
- a heating element;
- an interior portion, the interior portion defining a depression extending upwardly, the depression having a depth and a diameter, wherein the depth is less than the diameter, wherein the depression receives and forms an interference fit with the heating element;
- and
- a substantially horizontal section extending between the periphery and the depression;
- wherein the heating element includes a cylindrical metal canister including a metal upper wall, a cylindrical metal sidewall and a metal lower wall, wherein a diameter of the lower wall of the canister is less than a diameter defined by the periphery, wherein the depression is a cylindrical depression and wherein the interference fit is formed between an outer surface of the cylindrical metal sidewall of the canister and a cylindrical surface of the depression;
- wherein the substantially horizontal section and the metal lower wall of the canister are coplanar.
