Abstract: A structure for cooling having a cover and a water-retentive member, wherein the water-retentive member includes a bag and a water-absorptive material disposed inside the bag, wherein the water-retentive member is disposed inside the cover, wherein the first side of the cover having a moisture-permeability of 500 to 3,000 g/m2·24 hours, as determined by the Lyssy Method; a first side of the bag is moisture- or water-permeable; and at least one of a second side of the cover and a second side of the bag is water-impermeable.

Abstract: The self-heating and adhesive device of the present invention comprises a gas-permeable sheet layer, an exothermic composition layer, a gas-impermeable sheet layer, a support, a poultice or gel layer, and a releasing sheet layer in this order, wherein the exothermic composition layer is stuffed in a pouch that is made of the gas-permeable sheet layer and the gas-impermeable sheet layer, and wherein the support comprises a fibrous layer only or a gas-impermeable sheet and a fibrous layer and has a moisture permeability within the range of 0 to 3,000 g/m2·24 hours by the Lyssy method.

Abstract: A sheet-like face pack and kits for face packs are provided. The pack comprises a pouched part having an air-permeable side and an air-impermeable side, a substrate layer for gel that is set on the outer surface of the air-impermeable side, a gel layer that is set on the substrate layer, and an exothermic composition that is put into the pouched part, wherein a moisture permeability of the air-permeable side is within the range of 300 to 2,300 g/m2·24 hours by the Lyssy method, and wherein the temperature of the gel layer reaches 38° C. within 10 minutes after the exothermic composition starts to contact oxygen and is then maintained between 38° C. and 45° C. for 20 minutes or more, wherein the temperature of the gel layer is determined according to the method for determining a temperature based on JIS S 4100.

Abstract: The device of the present invention comprises a moisture-permeable base material, a water-bearing gel, and a covering material, which are laminated in this order. The base material comprises a moisture-permeable material, e.g., a cloth material made of a natural and/or artificial fiber, a polymeric film, or a polymeric sheet. The base material may be a laminate. The water-bearing gel comprises a water-absorbable polymer and water. The covering material may comprise a cloth material made of a natural and/or artificial fiber, a polymeric film, or a polymeric sheet. The device can be warmed or cooled. When it is warmed, it can evolve steam that results from water in the gel. Thus, it can be used to give moisutre to and warm up human body, or to cool down it.
