A beverage heating system is provided that enables hot beverages, such as coffee or tea, to be enjoyed at a desired temperature for a longer period of time, without requiring the beverages to be reheated, and without requiring any external power source. The system comprises a hot beverage reservoir, for receiving a hot beverage for consumption therefrom; and a self-heating element, configured to heat a base portion of the hot beverage reservoir, during consumption therefrom, to maintain a desired temperature of the hot beverage, without requiring any external power. The self-heating element may be configured to heat based upon an exothermic reaction.

A self-heating assembly includes a product tray for containing a product to be heated and a heater tray outside the product tray and configured relative to the product tray to define a reaction space between the heater tray and the product tray. A frangible container made of a shrink film material is inside the reaction space. The frangible container contains a first reactant that is a liquid. A second reactant is outside the frangible container. The first and second reactants are configured to react exothermically upon contact with each other.

An expandable, exothermic gel-forming composition that is predominately useful in the consumer products and medical industries. More particularly, it relates to the use of expandable particulate exothermic gel-forming compositions with efficient and long-lasting heat production for heating surfaces and objects without the need for electricity or combustible fuel.

A transportable device for heating foodstuffs includes a container for receiving the foodstuff as well as a closed-off heating chamber which adjoins the container and is thermally coupled thereto while simultaneously being hermetically separated therefrom via a shared, thermally-conductive wall. The heating chamber includes a first chamber and a second chamber that are separated by a water vapor-permeable wall. In the first chamber is a substance or a substance mixture which, when a liquid, preferably water, is supplied, generates heat in an exothermic chemical reaction with water vapor being formed. In the second chamber, a zeolite is located which can adsorb the water entering from the first chamber via said water vapor-permeable wall, generating heat. A transportable heating element which can be used in the device contains a hermetically-sealed heating chamber that adjoins a thermally-dissipating outer wall.
