<p>PURPOSE:To obtain a chemical body warmer having low initial temperature and capable of keeping a high and constant temperature for a long time, by adding zirconium powder to a chemical body warmer composed of iron powder, activated carbon, chemicals, etc. and generating heat by crumpling. CONSTITUTION:In a chemical body warmer composed of iron powder, activated carbon and chemicals, etc., expecially a chemical body warmer composed of the A-component consisting of iron power and the B-component consisting of activated carbon impregnated with chemicals and water, and crumpling the warmer in use to mix the A-component and the B-component, zirconium powder is added to the B-component to obtain the objective chemimcal body warmer. EFFECT:In contrast with the conventional body warmer wherein the temperature decreases at the latter stage of use, the temperature of the present body warmer increases by the heat of infrared radiation emitting from zirconium.</p> |
