際の発熱調整が充分でない欠点がある。Recently, warmers have been used to keep warm in winter or at night. These recent body warmers used to have a structure that gradually burned fuel such as benzine, but instead of the old ones, they put a large amount of iron particles in one bag and an oxidizing agent in the other bag. When used, the wall that shields the iron particles and the oxidizing agent is broken and the two are mixed to generate heat. However, these recent warmers have a drawback in that they do not adequately adjust the heat generated when warming the body.

ことによっても可能である。The inventor of the present invention, while considering the above-mentioned problems, discovered that the reason why the heat generation amount adjustment in conventional body warmers is not sufficient is that, for example, if the wall that shields the iron particles and the oxidizing agent is broken. For example, he realized that most of the iron particles undergo an oxidation reaction almost simultaneously, and therefore it is difficult for the exothermic reaction to proceed gradually, so he thought of effective measures to make the exothermic reaction gradually proceed. As a result, they realized that particles of oxidizing substances, such as fine iron particles, which exhibit an exothermic reaction due to oxidation reactions, could be coated with a resin so that their surfaces were covered, and they accomplished the present invention. . In addition, the particles of the oxidizing substance that exhibits an exothermic reaction due to the oxidation reaction in the present invention include, for example, the above-mentioned iron particles and aluminum particles, but are not limited to these particles, and the particle size of these particles There are also no special restrictions regarding the shape. Examples of resins that cover the surfaces of these oxidizing substance particles include polyurethane, polyisocyanate, phenol resin, polyester, polyamide, polyvinyl alcohol, polyvinylpyrrolidone, epoxy resin, gum arabic, gelatin, carboxymethyl cellulose,
Methyl cellulose, ethyl cellulose, acrylic resin,
Synthetic resins or natural resins such as vinyl acetate resin and polyvinyl butyral can be used as appropriate. As a method for coating the surface of particles of oxidizing substances such as fine iron particles using such a suitable resin, for example, a spray drying method as described in Japanese Patent Publication No. 52-36525, or There are methods such as phase separation from an organic solvent. When coating the surface of particles of oxidizing substances such as fine iron particles with resin using these methods, care must be taken to ensure that the coating film is easily destroyed when an appropriate external pressure is applied to the coated material. Instead of coating the surface of each particle with a resin, as shown in FIG.
! In other words, it is desirable to have an appropriate space 3 between the particles 11WI of the oxidizing substance in the coating film 2, so that the particles have a structure similar to that of microcapsules. It is desirable that In other words, if there is an aggregate of oxidizing substance particles inside a microcapsule, if external pressure is applied to this microcapsule, the shape of the oxidizing substance particle aggregate will change depending on the external pressure. However, the microcapsules are easily destroyed. Then, the heat-generating material of the present invention, which is like a microcapsule using the above-mentioned core material and the particles of the oxidizing substance and the child material, is applied to the skin of the body,
When the polymer layer of the microcapsules on the surface is destroyed by the pressure of a finger, the particles of oxidizing substances come into contact with the outside air, an oxidative exothermic reaction occurs, and it becomes possible to warm up. In order to promote the oxidation reaction of particles of oxidizing substances, the present invention uses a gaseous oxidizing agent such as oxygen, a liquid oxidizing agent such as hydrogen peroxide, or a solid oxidizing agent such as manganese dioxide. It can also be used in combination with other exothermic materials. By microcapsulating this gaseous or liquid oxidizing agent, it can be handled in the same way as a solid oxidizing agent. Note that the solid oxidizing agent may also be microencapsulated in the same manner as the exothermic material of the present invention. When using the heat-generating material of the present invention, it is possible to mix it into a paste such as glycerin and apply it, or as shown in Figure 2. A conceivable method is to apply the heat-generating material 5 according to the present invention in a pap-like structure with a paste-like binder 6 containing an oxidizing agent on the base film 4. In addition, with the heat generating material of the present invention, if the coating film is broken only in the necessary parts, the oxidizing substance in that part undergoes an oxidative exothermic reaction, so it is possible to provide warmth only to the truly necessary parts. It can also be used as moxibustion. Furthermore, by appropriately adjusting the extent to which the coating is destroyed, that is, the external pressure, the rate of destruction of the coating can be adjusted, and therefore the amount of heat generated, that is, the degree of warmth, can also be adjusted. Note that the degree of heating can also be adjusted by adjusting the mixing ratio of the oxidizing agent and the like, and by adjusting the mixing ratio of the exothermic material in the paste.

In other words, it can be used little by little, rather than just breaking the bag like with conventional body warmers, and it can be used little by little, and when storing conventional body warmers, if the bag is torn, the whole thing is destroyed. In contrast, the products of the present invention can be used even if one resin coating is torn as long as the other resin coatings are intact, and they cannot be directly applied or pasted on the body. Since it can be used, it has the advantage of having a wide range of applications.
