It is formed on the heat insulating material 3 so as to be 0 to 80%, preferably 50 to 70%. If the area of the through holes 31 is less than 30%, the cold heat of the freezing composition layer 2 cannot be sufficiently transferred to the antifreezing composition layer 1, and therefore, the cooling heat transferred from the multi-layered cooling material T to the head is not. It is not preferable because it has a poor feeling and cannot be put to practical use. On the other hand, if it exceeds 80%, the cold heat of the freezing composition layer 2 is excessively transferred to the antifreezing composition layer 1 and the multilayer coolant T
The cooling sensation transmitted from the body to the head is too strong, while the duration of the cooling effect tends to be short, which is not preferable.

That is, when the freezing composition layer 2 is divided into at least 2 or more, preferably 2 to 6, the coolant can be bent at the central portion, and the discomfort to the head is alleviated. preferable. It should be noted that if the degree of division is 7 or more, the frozen composition is likely to be melted and the durability of the cooling sensation is reduced, which is not preferable. The antifreeze composition layer 1 may be divided into a plurality of pieces and similarly arranged. Thereby, when the antifreeze composition is a sol, it is possible to prevent its localization, which is preferable.

As the bag 4, a film made of soft vinyl chloride, polyurethane, urethane-vinyl chloride copolymer, modified polyolefin, or the like, which has excellent low-temperature characteristics, can be used. Note that, as shown in FIG. 2, it is preferable to use a composite film obtained by quilting a thin foam because the soft feeling on the head is further improved.

Since the composition layer is partially contacted with the composition layer, the cold heat of the freezing composition is once transferred to the antifreezing composition layer and then transferred to the head, so that the head has an appropriate softness. It becomes possible to give a cold feeling. Further, since the heat transfer mechanism having the above-mentioned configuration is formed, heat transfer from the head to the freezing composition layer is suppressed on the contrary, so that cold heat from the freezing composition layer is continuously supplied for a long time. Become. Further, since the antifreezing composition layer and the freezing composition layer are arranged to face each other via the heat insulating material, and the freezing composition layer is divided into a plurality of parts, the cooling material is provided in the central portion. It becomes possible to bend, the discomfort to the head is relieved, and the fit to the head is excellent.

れる。As described in detail above, in the multi-layered cooling material of the present invention, the antifreezing composition layer and the freezing composition layer are arranged opposite to the heat insulating material, and the through holes are formed in this heat insulating material. Since the antifreeze composition layer and the freezing composition layer are formed so as to partially contact with each other, the cold heat of the freezing composition is once transferred to the antifreezing composition layer and then to the head. It will be transmitted, and it will be possible to give a moderate soft sensation to the head. Further, since the heat transfer mechanism having the above-mentioned configuration is formed, heat transfer from the head to the freezing composition layer is suppressed on the contrary, so that cold heat from the freezing composition layer is continuously supplied for a long time. Become. Further, since the antifreezing composition layer and the freezing composition layer are arranged to face each other via the heat insulating material, and the freezing composition layer is divided into a plurality of parts, the cooling material is provided in the central portion. It becomes possible to bend, the discomfort to the head is relieved, and the fit to the head is excellent. Therefore, according to the present invention, compared to the conventional one, an appropriate cooling feeling lasts for a long time,
Moreover, it is possible to obtain a multi-layered coolant excellent in fit to the human body.
