摘要:
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.

A self-heating fluid connector (35) comprising a housing (37) in which is provided exothermic phase change material (38) and one or more fluid channels extending from one end of the housing (37) to the other, in thermal communication with the exothermic phase change material, whereby fluid passing through the fluid conduits is heated by the exothermic phase change material. The self-heating connector is particularly suited for use with a fluid container (11) and a fluid delivery port (12) such as a baby's bottle and feeding teat.

This invention relates to a self-heating or self-cooling container (1), which uses an exothermic or endothermic re-action to provide or remove heat from the contents of the container. The chemical reaction includes a fluid consistuent (either as a reagent or solvent), held in a reservoir (6), which is added to another reagent in the reaction chamber (5) to initiate the reaction. The container (1) according to the invention proposes a means (8, 91) to control the volume of this fluid constituent added to the reaction chamber (5) depending on the ambient temperature of the container.

A container assembly heats or cools a product inside an inner container. An outer jacket at least partially surrounds the inner container, with a first internal volume and a second internal volume in the space between the outer jacket and the inner container. A first temperature-change reagent is contained inside the first internal volume, and a second temperature-change reagent is held in the second internal volume, with a reagent separator between the two. Several penetrators are disposed to penetrate the reagent separator to produce openings through the separator and through which the two reagents can mix. Steel wool inside the first internal volume acts as a steam condenser. The outer jacket includes a jacket top ring secured around an upper surface of a standard can, a jacket body secured to the jacket top, and a flexible jacket bottom that carries several spikes molded onto the jacket bottom.

A food or beverage container includes a receptacle and an assembly for generating a change in temperature. The assembly includes two reactive components in a housing and which are separated from each other by a frangible member within the receptacle. The receptacle includes a wall with a movable portion and which opposes a movable part of a housing wall, and means for transmitting movement of the movable portion to the movable part of the housing wall. A liquid is disposed inside the receptacle and at least partly surrounds the housing.

The invention relates to a multi-compartment bag which provides for the separation of two substances until their desired intermixing. A specific application of this multi-compartment bag is for hot or cold chemical packs. The substances in the multi-compartment bag are separated by two breakable walls and a third compartment which together act as a barrier to migration of one substance into the second substance, which would reduce the shelf life and efficiency of the hot or cold chemical pack. The present invention's use of two breakable walls and a compartment, empty or containing an inert substance, separating two reactive substances, provides a longer shelf life, a high efficiency, more reliability and improved ease of operation.

A container having a container body, a thermic module, and a closure heats or cools its contents by initiating a chemical reaction inside the thermic module when a user activates the container. The thermic module may include a module cap and a module body. Two reactants, such as calcium oxide and water, are retained in portions of the thermic module and separated by a barrier that is punctured when a user activates the container, thus allowing them to mix. The cap may have vent channels between surfaces of the module cap and the module body that allow gases to vent, yet prevent escape of unsightly solid particles. A filter ring may be included in the path of each vent channel to further prevent such escape.

This invention is a portable heat source that may be used to warm food, beverage or other supplies. The heater material is a solid that may be stored for long periods of time, and activated by addition of water or an aqueous solution. The heater consists of an acidic anhydride or salt together with a basic anhydride or salt, such that addition of water to both acidic and basic anhydrides produces heat as well as acid and base respectively; subsequent reaction of the acid and base produces additional heat, as well as a safe, neutral product that is easily disposed. The invention further consists of means to regulate the rate of heat production by the use of additives and processing methods, so that heat is produced at a rate compatible with the rate at which the food or other materials can absorb the heat. The invention further consists of devices incorporating the materials to be heated in an advantageous arrangement with the heater composition.

This invention relates to a self-heating container for heating beverages or food contained within the container. The self-heating container or can includes a cup containing active lime that is positioned underneath a thin plate and another cup filled with water. When a bottom cover of the self-heating container is pressed downwardly, sharp spikes above the water cup pierce a thin plate located between a chamber containing the water and the active lime and causes the water inside the cup to flow into the active lime which results in a chemical reaction that heats the contents of the can or container.
