COLD RESERVING MATERIAL AND HEAT RESERVING MATERIAL USING GEL AND PILLOW, FOOT-WARMING TOOL AND FACE MASK USING THOSE

摘要

PROBLEM TO BE SOLVED: To provide a cold reserving tool and a heat reserving tool in which the hardness and repulsive property are adequately adjusted from the viewpoint in which the head and the neck or the foot are stably retained and the extent cooling the head and the neck or warming the foot is adequately adjusted from the viewpoint transferring to a sleeping condition and to provide a pillow, a foot-warming tool and a face mask using those.;SOLUTION: The cold reserving material or the heat reserving material is obtained by using gel containing a latent heat storing agent. In the cold reserving material, the melting point of the latent heat storing agent is kept to 5-20°C and the content of the latent heat storing agent is 20-60 wt.% based on total amount of gel and when the temperature of the gel containing the latent heat storing agent is set to 5°C and allowed to stand under the atmosphere of 26°C, the gel is kept for at least 2 hr in the range of 5-20°C and compressive stress is set to 10-90 kPa and hysteresis loss is set to 20-50% when the temperature of the gel containing the latent heat storing agent is set to 5°C.;COPYRIGHT: (C)2005,JPO&NCIPI
