It is formed in a possible shape. Since the shape of the cooling medium 8 is substantially similar to the shape of the storage section 4, the cooling medium 8 can be stored in as large an area of the storage section 4 as possible, and the storage area of the limited area can be reduced. The cooling medium 8 can be stored and installed in the storage unit 4 having a maximum area, and the efficiency of cooling the human head is significantly improved. Desirably, the shape of the cooling medium 8 that can be accommodated and installed in approximately 40% or more of the area of the head cooling tool is more desirable, and more desirably, the shape of the cooling medium 8 that can be accommodated and installed in an area of about 80 to 99%.
For example, as shown in FIG. 1B, the shape of the storage portions 42 and 43 is substantially semicircular, or as shown in FIG. 2B, the shape of the storage portions 421 and 423 is substantially fan-shaped. In this case, it is desirable that the shape of the cooling medium 8 be substantially similar to the shape of the storage portion 4 and be a shape that can be stored in the entire area of the storage portion as much as possible. When the shape of the storage section 4 is large, a plurality of divided connection parts which are divided into a plurality of pieces and connected to each other by using a sealed cooling medium 8 filled in a plastic bag container as shown in FIG.

It is. When the temperature of the cooling medium 8 is about -5 to about 2 ° C., which is lower than about 2 ° C., the user feels discomfort due to slightly too strong strong cooling, and when the temperature is lower than about −5 ° C., It feels extremely cold and becomes a "super-cooled" state unsuitable for use. If the temperature is higher than about 15 ° C., the cooling sensation tends to be weakened and the cooling effect of cooling the human head tends to be lost.
On the other hand, a sealed cooling medium containing a medium containing a water-soluble polymer, polyhydric alcohol, water, or the like as a cooling medium in a sealed container is a gel (or a liquid or a gel) having fluidity at room temperature. In addition, the viscosity increases with a decrease in temperature, and tends to become a hard lump through a semi-solid state. From the viewpoint of a feeling of wearing when worn on a human head, a gel (or gel) is formed. From soft to clay-like (or semi-solid) soft and soft feel and soft feel is desirable.

When the temperature exceeds ℃, the duration of comfortable cooling when worn on the human head is significantly shortened, and a feeling of cooling tends not to be obtained. More desirably, the cooling temperature of the cooling medium 8 housed in the housing part is preferably about −20 ° C. to about 5 ° C. When the head cooling tool containing the cooling medium 8 cooled to this temperature range is mounted on the human head, the comfortable cooling duration tends to be long. The optimum cooling temperature of the cooling medium 8 can be selected and implemented according to the heat insulating performance of the sheet-like surface member 2 and the sheet-like inner surface member 3 constituting the head cooling tool and the type of the cooling medium.

In the head cooling tool of the present invention, (a) the heat insulating performance of the storage portion 4 of the head cooling tool 1 is improved by forming the sheet-like surface member 2 provided with the heat insulating material 22. It is designed to prolong the cooling duration by suppressing as much as possible the cool air escaping from the surface. (B) Regarding the area ratio of the cooling medium 8 of the head cooling tool 1 covering the head, the storage unit 4 is divided into a plurality of storage units 4 that cover the entire head, and the cooling medium is provided in each storage unit 4. 8 has a configuration in which it can be mounted so as to cover the entire human head.

Occasional discomfort tends to occur. (D) The cooling duration becomes longer as the volume (weight) of the cooling medium 8 of the head cooling tool 1 increases, however, since it feels heavy when worn, it tends to feel stress on the human head and neck. is there.
From such a viewpoint, the thickness of the cooling medium 8 stored in the storage section 4 is desirably about 3 to about 15 mm, more desirably, about 5 to about 13 mm. The shape of the cooling medium 8 is similar to the shape of the cooling medium 8 and can be accommodated and installed in approximately 40% or more of the area of the head cooling tool. If the area occupied by the cooling medium 8 is less than about 40% of the area of the shaped head cooling tool, the cooling duration tends to be short. More preferably, the area occupied by the cooling medium 8 is preferably about 80 to 99% of the area of the shaped head cooling tool.

<About the measurement results of Examples 1 to 3>
In Table 1, in the head cooling tools of Examples 1 to 3 in which the sheet-like surface member 2 was composed of a heat insulating material and the sheet-like inner surface member 3 was composed only of a mesh cloth material, the sealing cooling medium 8 was used. When the surface temperature of the sheet member on the inner surface side is “about 2 ° C. to about 15 ° C.”, the “comfortable wearing time” is about 90 minutes in each case.
In Embodiments 1 and 3 in which the storage opening is formed in the sheet-like surface member, the first and third embodiments have a cooling opening of about −15 ° C. in about 20 minutes compared to Embodiment 2 in which the storage opening is formed in the sheet-like inner surface member.

<About the measurement result of Example 4>
In the head cooling tool according to the fourth embodiment in which the sheet-shaped head protection member 7 is formed on the inner side of the head cooling tool according to the third embodiment, the “comfortable wearing time” is about 120 minutes. In other words, by installing the sheet-shaped head protection member 7 between the human head and the cooling medium, the temperature of the cooling medium that is too cold reaching the human head is reduced to a comfortable temperature range, and the “comfortable wearing” Time can be extended. In the case where the sheet-shaped head protection member 7 of this embodiment is configured, the temperature reaching the human head is reduced by about 4 to 5 ° C. by interposing the sheet-shaped head protection member 7. By changing the type of the part protection member 7, a head cooling tool adjusted to a desired temperature can be obtained.

<About the measurement result of Example 5>
In the head cooling tool of Example 5 in which a material having the same heat insulating property as the sheet-like surface member configured in the head cooling tool of Example 3 was configured as the sheet-like inner surface member, the “comfortable wearing time” was 210 minutes. . That is, by using a material having high heat-insulating performance as a constituent material of both the sheet-like surface member and the sheet-like inner surface member, and the cooling medium is stored in the storage portion having high heat-insulating properties, the human body head By relaxing the temperature of the cooling medium that has reached too cold to a comfortable temperature range, the “comfortable mounting time” can be prolonged, and further, the heating rate of the cooling medium can be reduced to increase the “comfortable mounting time”. Can be long.

<About the measurement result of Example 6>
The sheet-like surface member 2 constitutes a heat-insulating material that does not contain a metal thin film, the sheet-like inner member 3 constitutes a heat-insulating material that does not contain a metal thin-film, and the sheet-like surface member 2 is higher than the sheet-like inner member 3. In the head cooling tool of Example 6 having heat insulation properties, the “comfortable wearing time” is 165 minutes. That is, by using a material having high heat-insulating performance as a constituent material of both the sheet-like surface member and the sheet-like inner surface member, and the cooling medium is stored in the storage portion having high heat-insulating properties, the human body head By relaxing the temperature of the cooling medium that has reached too cold to a comfortable temperature range, the “comfortable mounting time” can be prolonged, and further, the heating rate of the cooling medium can be reduced to increase the “comfortable mounting time”. Can be long. However, the "comfortable wearing time" tends to be slightly shorter when compared with the head cooling tool of Example 5 which has better heat insulation performance than this example.

<About the measurement result of Example 7>
The sheet-shaped surface member 2 constitutes a heat-insulating material that does not contain a metal thin film, the sheet-shaped inner surface member 3 constitutes an inner-surface member cooling medium holding material 33, and a sheet-shaped head protection is provided on the inner surface side of the sheet-shaped inner member 3. In the head cooling tool according to the seventh embodiment in which the member 7 is configured, the “comfortable wearing time” is 105 minutes. That is, by using a material having high heat insulating performance as a constituent material of the sheet-shaped surface member and storing the cooling medium in the storage part having high heat insulating properties, the temperature of the cooling medium that reaches the head of the human body becomes too cold. Can be relaxed to a comfortable temperature range and the "comfortable mounting time" can be prolonged, and further, the "comfortable mounting time" can be prolonged by slowing down the temperature rise rate of the cooling medium. However, when compared with the head cooling tool of Example 4 in which the sheet-like surface member 2 has better heat insulating performance than in this example, the “comfortable wearing time” tends to be slightly shorter.

<About the measurement result of Example 8>
In the head cooling tool of Example 8 in which only the mesh-like material is formed on both the sheet-like surface member and the sheet-like inner surface member, the “comfortable wearing time” is about 60 minutes. In other words, it is conceivable that the amount of cool air escaping from the surface of the head cooling tool increases, so that the cooling maintenance time of the cooling medium is shortened.
