Abstract: An object of the present invention is to provide a heat generating body giving no uncomfortable feeling when in use and causing no direct close contact between a heat generating member and the skin by an adhesive to relieve the burden of the skin while eliminating a low temperature burn even for a person with a delicate skin and in the case of continuous use. The heat generating body of the present invention is characterized in that the heat generating member having a wide surface is provided on a mesh-like sheet larger in outer shape than the one-side wide surface of the heat generating member and that an adhesive layer is provided on the mesh-like sheet located at the outer peripheral part of the heat generating member.

Abstract: A heat generating body including a a moldable heat generating composition containing surplus water as a connecting substance interposed and heat sealed between packaging materials, which is characterized in that the packaging materials are each constituted of a substrate and a covering material; that the substrate is substantially planar and does not have an accommodating pocket; that the packaging materials each has a bending resistance of not more than 100 mm; that the packaging materials are each a non-elastic body at least at a temperature between 25° C. and 60° C., has a breaking strength of 500 g/mm2 or more at 25° C. and has a breaking elongation of 30% or more at 90° C. The heat generating body is suitable for relaxation of symptoms of menstrual pain.

Abstract: A heat generating body wherein three or more plural sectional exothermic parts are provided at intervals via a sectioned part which is a heat seal part. The sectional exothermic parts have a heat generating composition capable of causing heat generation upon contact with oxygen in air and are at least constituted of three kinds of a low temperature sectional exothermic part, a middle temperature sectional exothermic part and a high temperature sectional exothermic part. A maximum temperature of the high temperature sectional exothermic part is higher than a maximum temperature of the low temperature sectional exothermic part. A maximum temperature of the middle temperature sectional exothermic part is between a maximum temperature of the high temperature sectional exothermic part and a maximum temperature of the low temperature sectional exothermic part. The middle temperature sectional exothermic part is constituted of plural sectional exothermic parts having a different maximum temperature.

Abstract: There is provided such a heat-generating body for warming a foot in that a heat-generating composition is used that can retain the shape thereof irrespective of the pressure inside the container bag upon using by application to a foot, a footgear or a sock. The heat-generating body of the invention for warming a foot is characterized in that it contains a heat-generating formed article causing a heat-generating reaction in the presence of air and having a shape retaining degree of 70 or more charged in a container bag constituted with a base material, a covering material and the like. Further a process is provided for producing a heat-generating body for warming a foot in that the heat generation reaction of the heat-generating composition is suppressed to prevent loss due to the heat-generating reaction during production, quality deterioration of the heat-generating composition, and other problems.
