Abstract: A self-heating container is capable of generating heat by hydration of an exothermic reaction agent and includes a body, a cover for closing the body, an inner container placed in the body for containing foodstuff to be heated, a primary water bag for supplying water for initial hydration, and an envelope enclosing an exothermic reaction agent and a secondary water bag. The amount of water necessary for hydration of the exothermic reaction agent is divided between the primary and secondary water bags so that water may be supplied in two stages to avoid violent eruption of hot steam due to hydration. In operation, the primary water bag is, after opened, removed from the body to discharge water for the initial hydration of the exothermic reaction agent which generates heat for rupturing the secondary water bag. Then the secondary water bag discharges water for further hydration.

Abstract: The unit delimits two compartments which are intended to contain each one product and which are separated by a separating element constituted by at least one cover perforatable as a result of the manipulation of a mixing perforator. This perforator is placed into one of the compartments, so that its cutting end comes to be near the above-mentioned separating element in the storage position, and that its other end is situated opposite a deformable obturating partition of the compartment. An element for manipulating the perforator is disposed in the extension of this latter, on the other side of the partition; it is displaceable for translation to pass from the storage position to a mixing position wherein it is acting on the perforator through the partition to cause it to cut the separating element. Can be used for storing a hair dye.

Abstract: A container for self-heating or self-cooling drinks or foodstuffs housed in the container has a diaphragm and a breaker capable of completely shattering the diaphragm with ease for delivering a liquid reactant to an exothermal or endothermal solid reactant. The container is partitioned into three chambers. One chamber contains drinks and foodstuffs, one contains exothermal or endothermal solid reactants, and one contains a liquid reactant. The diaphragm is made of thin prestressed glass partition between the reactant chamber containing the exothermal or endothermal solid reactant and the chamber containing the liquid reactant. Actuation of the breaker forms a large hole by shattering the prestressed glass diaphragm. The liquid reactant passes through the hole and contacts the exothermal or endothermal reactant, and the ensuing exothermal or endothermal reaction releases or absorbs energy to rapidly heat or cool the drinks or solid foodstuffs.

Abstract: A self-contained heat recoverable exothermic chemical heater to provide heat to a recoverable sleeve. The heat recoverable heater provides superior thermal contact as the sleeve recovers and, in particular, after recovery when additional heat is required to melt an adhesive. A first and second heat bag, each having a different chemical means disposed in its separate compartments, are bonded together. The separate compartments maintain the correct proportions and proper distribution of the chemical means for optimum mixing. The rupturable barrier enclosing each of the compartments can be almost totally removed to allow the rapid and complete mixing of the chemical means without permitting any of the chemical means to escape. The removal of the rupturable barrier causes the chemical means to mix, thereby generating heat. The adhesive partitioning the heat bags into separate compartments releases its bond as a result of the increasing temperature.
