Title:
HEATING ELEMENT
Document Type and Number:
WIPO Patent Application WO/2006/006652
Kind Code:
A1
Abstract:
A heating element that safely secures space on the periphery of exothermic composition to thereby realize thermal insulation of the exothermic composition, regulating of the amount of air taken inside and prevention of moisture scattering. There is provided a heating element produced by superimposing on a base material an exothermic composition molding being a molding of an exothermic composition capable of generating heat upon contact with air, effecting covering with a covering material and heat sealing the periphery of the exothermic composition molding so as to have a heating section having the exothermic composition molding accommodated at projected portions of an accommodation bag furnished with multiple projections and depressions, characterized in that the exothermic composition comprises, as indispensable components, an exothermic substance, a carbon component, a reaction accelerator and water, and that the heating element is composed of compartmentalized heating sections and compartmentalization sections, the compartmentalized heating sections adapted to accommodate the exothermic composition molding, the compartmentalization sections consisting of seal portion, and that the compartmentalized heating sections are disposed with compartmentalization section interposed therebetween, and that at least parts of the compartmentalized heating sections have air permeable surfaces, which air permeable surfaces brought into contact with the exothermic composition molding are constituted of a water nonadsorbent material, and that there are steps between the compartmentalized heating sections and the compartmentalization sections, which steps are covered via an adhesive layer by an air passage regulating member to thereby provide partitioned space portions, the space portions fitted with a main air inlet.
