Method of manufacturing a heat-generating body for warming foot and foot temperature for heating element

摘要

PROBLEM TO BE SOLVED: To provide a leg-warming exothermic body which can be adhered to legs, footwears and socks to use, employs an exothermic composition which can keep its shape regardless of an atmosphere inside the bag in order to prevent from moving within the bag, and can be worn to fit for a leg shape and to warm a desired region efficiently for a long time; and a method for producing the leg-warming exothermic body which can inhibit and prevent the exothermic composition from exothermic reacting resulting in the production loss, the quality leveling-down, and the solidification troubles in the production, can employ moulding, printing such as gravure printing, and coating for transfer and laminate, can disperse the nonviscous exothermic composition uniformly, can laminate at an increased accuracy to stabilize the production quality, can produce an ultrathin to thick exothermic composition simply and in a low cost.;SOLUTION: The exothermic composition can bring about exothermic reaction in the presence of air, has a shape retention of 70 or more, and is packed in a holding bag composed of a base material, a coating material and the likes, wherein the holding bag has at least one gas permeable part.;COPYRIGHT: (C)2004,JPO
