Patent ID: 7652228

Claim:
A steam-generating warming article comprising a steam generating warming sheet which is adapted to supply steam while in contact with the surface of the body, wherein said steam generating warming sheet comprises a heat generating sheet having a large number of holes or cuts and a holder for holding said heat generating sheet, said heat generating sheet being a molded sheet comprising an oxidizable metal, a reaction accelerator, and a fibrous material, having incorporated therein an aqueous electrolyte solution, and wherein said heat generating sheet generates heat upon contact with air, wherein the molded sheet contains 60% to 90% by weight of the oxidizable metal, 5% to 25% by weight of the reaction accelerator, and 5% to 35% by weight of the fibrous material, and wherein the heat generating sheet comprises 40 to 80 parts by weight of the aqueous electrolyte solution containing 1% to 15% by weight of an electrolyte per 100 parts by weight of the molded sheet said holder having air permeability in at least a part thereof to allow steam to be released outside through said holder, and an air permeable part of said holder having a water vapor transmission rate of 300 to 2000 g/m 2 ·24 hr (JIS Z0208, 40° C. 90% RH).
