PROBLEM TO BE SOLVED: To provide a water pad which has a soft and pleasant feeling, is highly hygienic, has an excellent heat exchange feature with a body since it fits to the shape of a body, shows excellent heat-exchanging performance with a use atmosphere because of the high moisture permeability, and never cools excessively.SOLUTION: The cooling water pad is configured by filling a pouch body which has a layer structure comprising a non-woven fabric made of a water-absorbent fiber, a water-absorbent base material film, and a heat-sealing layer with water and sealing it. A high cooling effect is obtained by bonding the water-absorbent base material film in an exposed state to the non-woven fabric since the water in the pouch body seeps out on a surface to vaporize and removes heat. In addition, the amount of water is easily measured by providing a measurement chamber that is sandwiched between two zippers, providing a pouring tool to which a polyethylene terephthalate or PET bottle is directly connected, or the like in order to prevent the rupture of the pouch due to the overfilling of water or an insufficient cooling effect due to the insufficient amount of water.COPYRIGHT: (C)2013,JPO&INPIT【課題】肌触りが良く、衛生性に優れ、体型に良くなじむため身体との熱交換機能に優れ、高い透湿性によって、使用雰囲気との熱交換性に優れ、かつ、冷やしすぎることの無い水パッドを提供することを目的とする。【解決手段】層構成が吸水性繊維からなる不織布、吸水性基材フィルム、および、ヒートシール性層からなる袋体に水を充填し、密封してなる冷却用水パッド。吸水性基材フィルムが露出した状態で不織布と貼り合わせることにより、袋体内の水が表面に滲み出て気化して熱を奪うため、高い冷却効果が得られる。また、2本のジッパーに挟まれた計量室を設ける、PETボトルを直接接続できる注出具を設ける等によって、水の計量を容易にし、水の入れすぎによる破袋や、水量不足による冷却効果不足を防止する【選択図】図1
