Abstract: A microwavable single-serving meal container comprising a microwavable meal tray containing a food product; and a microwavable polyurethane foam shell having a shape adapted to substantially conform to the shape of the meal tray, said foam shell enveloping the meal tray and thus the food product during microwaving of the food product to thereby retain microwave induced heat.

Abstract: A collapsible cooler apparatus includes a floor assembly which includes a quantity of a heat transfer material in a sealed floor module. A plurality of foldable wall assemblies are provided which include a lower wall subassembly, an upper wall subassembly, and an interior hinge connecting the lower wall subassembly to the upper wall subassembly. The lower wall subassemblies include respective quantities of a heat transfer material in respective sealed lower wall modules. The upper wall subassemblies include respective quantities of a heat transfer material in respective upper wall modules. A plurality of peripheral hinges are connected between the floor module and the lower wall subassemblies for securing the lower wall subassemblies to the floor assembly. Flexible corner panels are connected between adjacent foldable wall assemblies.

Abstract: A self-heating foodstuff container is capable of generating heat by utilizing an exothermic reaction and includes a body having a first chamber for containing a foodstuff and a second chamber for receiving an exothermic reaction agent, and a liquid container including a body portion and a conduit connected to the body portion for discharging the liquid into the second chamber. The body portion is disposed outside of the second chamber and is capable of contracting upon pressure. The container further includes a support member carrying the body portion and slidably mounted with respect to the body in such a manner that the sliding movement of the support member presses the body portion and causes the liquid to discharge through the conduit into the second chamber for initiating the exothermic reaction.

Abstract: A portable constant temperature box is formed of a box body and a lid, the box body being formed of a square bottom wall of adiabatic material, four side walls, and an external sheet. The side walls are connected to the bottom wall such that they can unfold and rise and the external sheet forms foldable connecting portions for connecting the side walls. A pair of retainers fix the connecting portions detachably to the side walls to thereby hold the side walls to rise upright respectively.
