Abstract:
Instant temperature changing device includes reactant and activator liquid that generate an exothermic or endothermic chemical reaction when combined to heat or cool contents in the device. One temperature changing device includes an inner shell and an outer shell, an activator container, and a reaction chamber. Opening the activator container causes reactant to combine with activator liquid and undergo an exothermic or endothermic reaction to initiate heat transfer to or from the contents disposed in the inner shell.
Abstract:
Self-heating containers comprise a reaction chamber and a heating chamber. The heating chamber is sized to contain a substance to be heated. The reaction chamber contains reactants which, when contacted, exothermically react. The reaction chamber is divided into a first compartment and a second compartment with a barrier therebetween. The barrier comprises a first barrier portion and a second barrier portion. The first barrier portion is attached to a reaction chamber wall and has an opening sized to allow reactants to flow through from one compartment to the other. The second barrier portion is attached to the first barrier portion to close the opening. The barrier can be opened by moving an actuator into engagement with the second barrier portion to dislodge the second barrier portion from the first barrier portion and thereby open the barrier. In certain embodiments, the heating chamber can be a can with prepackaged comestible substance therein. Examples of components configured to facilitate such a can are disclosed.
Abstract:
A heating device includes a sealed container and a sleeve inside the container. The sleeve defines an interior space adapted to be in fluid communication with reactants from a user-initiated exothermic chemical reaction. The sleeve has surfaces that respectively define a lower ventilation port between the interior space and a lower ventilation passage and an upper ventilation port between the interior space and an upper ventilation passage. The sleeve and the container have surfaces that cooperatively define the upper ventilation passage and the lower ventilation passage. The upper and lower ventilation passages extend at least partially around a perimeter of the sleeve. The container has a surface that defines an exit port that facilitates fluid communication from the upper and lower ventilation passages to outside.
Abstract:
Chemical heating using a first reactant, a second reactant and a complexing agent adapted to complex reversibly with the first reactant and, thereby moderate the reaction between the first and second reactants. The heating formula is particularly well suited for heaters that are used to heat materials having relatively high viscosities.
Abstract:
A heating or cooling device having a sleeve adapted to fit on or over an article to be heated or cooled, the sleeve having an outer layer and an inner layer, and at least one heat- or cold-generating chemical contained between the outer layer and the inner layer, where the device is constructed of a flexible material, and where the device has a re-closable seal to enable water or other chemical to be added to the at least one heat- or cold-generating chemical.

Abstract:
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.
Abstract:
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.
Abstract:
A self-heating or self-cooling container, which uses a chemical reaction to effect heating or cooling. The reagents for the chemical reaction are stored separately in two sealed compartments (5, 6) having a common dividing wall (7), which can move within the compartments to expand the volume of one compartment at the expense of the other compartment. This arrangement allows efficient use of space within the reaction module of the can, which is particularly important where large amounts of reagent are required to obtain the necessary heating or cooling effect and where the products of the chemical reaction occupy a significantly increased volume compared to the initial reagent in the compartment.
