Patent ID: 7036503

Claim:
A face-wearing humidifier being generally symmetrical about a longitudinal center line, comprising: a moisture-permeable skin-side surface sheet to be directed toward a skin; an outer surface sheet to be directed outward; a heat-generating composition for generating steam, said composition interposed between the skin-side surface sheet and the outer surface sheet, wherein the humidifier is divided into: a central non heat-generating belt extending along the longitudinal centerline; a pair of inner heat-generating regions located laterally outside but symmetrically about the central non heat-generating belt; lateral non heat-generating belts located laterally outside the inner heat-generating regions and extending longitudinally in parallel or not in parallel with but disposed symmetrically about the central non heat-generating belt; and outer heat-generating regions located laterally outside the lateral non heat-generating belts but symmetrically about the central non heat-generating belt, wherein the heat-generating composition, interposed between the skin-side surface sheet and the outer surface sheet, is disposed in the inner heat-generating regions and the outer heat-generating regions but not disposed in the central non heat-generating belt and the lateral non heat-generating belts, wherein the humidifier is deformable around the central non heat-generating belt and the lateral non heat-generating belts to follow the shape of a face.
