The present invention relates to a heat-generating body containing a heat-generating composition causing a heat-generating reaction in the presence of air sealed in an air permeable container body having a desired shape, such as a bag form, a sheet form and the like, and a cohesive layer provided. The invention aims to such an object that chill feeling to a human body upon application and in the initial service period, which is a problem of a water-containing hydrophilic gel, is reduced to provide a heat-generating body suitable for using as a heat-generating sheet agent or the like having a water-soluble hydrophilic gel cohesive agent layer excellent in usability, which is a heat-generating body containing a heat-generating composition causing a heat-generating reaction in the presence of air sealed in an air permeable container body having a desired shape, such as a bag form, a sheet form and the like, and a cohesive layer containing water-containing hydrophilic gel agent obtained from a hydrophilic polymer thickener provided on the container body, characterized in that the water containing hydrophilic gel agent contains an organic filler.
L'invention concerne un article générateur de chaleur, qui comprend un boîtier perméable à l'air, de forme voulue, tel qu'un sac ou une feuille et, contenue dedans, une composition produisant de la chaleur en présence d'air, ainsi qu'une couche adhésive comprenant un agent de gel hydrophile contenant de l'eau, obtenu à partir d'un épaississant polymère hydrophile. Ladite invention se caractérise en ce que l'agent de gel hydrophile contenant de l'eau comprend une charge organique. Comparativement à un article classique de production de chaleur comportant une couche adhésive comprenant un agent de gel hydrophile contenant de l'eau, ledit article produisant de la chaleur réduit la sensation de froid au moment de l'application et dans une période initiale d'utilisation auprès d'un utilisateur potentiel et n'induit par conséquent pas ce type de problème. Ledit article présente de ce fait d'excellentes propriétés en termes de sensation à l'usage.
