  As a result, “when the head cooling device is mounted on the human head, the cold air caused by the cooling medium 8 stored in the storage portion ventilates the sheet-like inner surface member 3 and easily reaches the human head. As a result, (b) head cooling with excellent cooling performance capable of cooling the entire head, and (c) long-term cooling maintenance performance with excellent long-term cooling maintenance performance are significantly improved.

Table 2 shows the results of the implementation when worn on the head.
When the surface temperature of the sheet-like member on the inner surface side where the sealed cooling medium 8 is located is “cool”, the temperature is “about 2 ° C. to about 15 ° C.” and is comprehensively evaluated as “comfort wearing time”. Table 2 shows the overall evaluation when the cooling tool is mounted.

<About the measurement result of Example 1- Example 3>
In Table 1, in the head cooling device of Examples 1 to 3 in which a heat insulating material is formed on the sheet-like surface member 2 and only the mesh-like cloth material is formed on the sheet-like inner surface member 3, The “comfortable wearing time” when the surface temperature of the sheet-like member on the inner surface side is “about 2 ° C. to about 15 ° C.” is about 90 minutes.
Example 1 and Example 3 in which the storage opening is formed with a sheet-like surface member are compared with Example 2 in which the storage opening is formed with a sheet-like inner surface member from a cooled state at about −15 ° C. There is no significant difference in the relationship between the “elapsed time and the surface temperature of the sheet-like member on the inner surface side” until reaching ° C.
However, although depending on the sense of the wearer, when the head cooling device of Example 2 in which the storage opening is formed with a sheet-like inner surface member is mounted, the slightly bulging shape of the double opening edge of the storage opening There is a tendency to feel uncomfortable due to.

<About the measurement result of Example 4>
In the head cooling device of Example 4 in which the sheet-like head protection member 7 is configured on the inner surface side of the head cooling device of Example 3, the “comfort wearing time” is about 120 minutes. That is, by installing the sheet-like head protection member 7 between the human head and the cooling medium, the temperature of the cooling medium that reaches the human head is reduced to a comfortable temperature range, “Time” can be long. In the case where the sheet-like head protecting member 7 of the present embodiment is configured, the temperature reaching the human head is lowered by about 4 to 5 ° C. by interposing the sheet-like head protecting 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 the material having the same heat insulating property as the sheet-shaped surface member configured in the head cooling tool of Example 3 is configured as the sheet-shaped inner surface member, the “comfort wearing time” is 210 minutes. . That is, a material having high heat insulation performance is used as a constituent material for both the sheet-like surface member and the sheet-like inner surface member, and the cooling medium is housed in the housing portion having the high heat insulation property. Reducing the temperature of the cooling medium that has reached too low to a comfortable temperature range can prolong the “comfort wearing time”, and further reduce the temperature rise rate of the cooling medium to reduce the “comfort wearing 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 surface 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 surface member 3. In the head cooling device of Example 6 having heat insulation properties, the “comfort wearing time” is 165 minutes. That is, a material having high heat insulation performance is used as a constituent material for both the sheet-like surface member and the sheet-like inner surface member, and the cooling medium is housed in the housing portion having the high heat insulation property. Reducing the temperature of the cooling medium that has reached too low to a comfortable temperature range can prolong the “comfort wearing time”, and further reduce the temperature rise rate of the cooling medium to reduce the “comfort wearing time”. Can be long. However, the “comfortable wearing time” tends to be slightly shorter when compared with the head cooling device of Example 5 having better heat insulation performance than the present example.

<About the measurement result of Example 7>
The sheet-like surface member 2 constitutes a heat-insulating material that does not contain a metal thin film, the sheet-like inner surface member 3 constitutes an inner-surface member cooling medium holding material 33, and the sheet-like head protection is provided on the inner surface side of the sheet-like inner surface member 3. In the head cooling device of Example 7 in which the member 7 is configured, the “comfortable wearing time” is 105 minutes. That is, the temperature of the cooling medium that reaches the human head due to the configuration in which a material having high heat insulating performance is used as the constituent material of the sheet-like surface member and the cooling medium is stored in the storage portion having high heat insulating properties. Can be relaxed to a comfortable temperature range, and the “comfort wearing time” can be made longer, and further, the temperature increase rate of the cooling medium can be slowed to make the “comfort wearing time” longer. However, when compared with the head cooling device of Example 4 in which the sheet-like surface member 2 has better heat insulation performance than the present example, the “comfort wearing time” tends to be slightly shorter.

<About the measurement result of Example 8>
In the head cooling device 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. That is, it is conceivable that the cooling maintenance time of the cooling medium is shortened because the cool air escaping from the surface of the head cooling tool increases.

<About the measurement result of Example 9>
Of the plurality of storage portions of the head cooling tool of the third embodiment, the sealed cooling medium 8 is stored only in the central storage portion 41 and is not stored in the left side storage portion 42 and the right side storage portion 43. In the head cooling device, the “comfortable wearing time” is about 60 minutes, and the “comfortable wearing time” is shorter than the “comfortable wearing time of about 90 minutes” of the third embodiment. Furthermore, in this embodiment, only a part of the human head is cooled, and a cooling feeling is felt only at the top of the human body, but the cooling feeling of the whole human head is not felt. There is a tendency to be inferior. Moreover, although it changes with people who wear | wear, there exists a tendency which feels uncomfortable in a wearing feeling by the unevenness | corrugation resulting from the shape of the installed cooling medium.
That is, the head cooling medium in which the cooling medium is housed in the entire human head is superior in the “comfortable wearing time” as compared with the head cooling tool in which the cooling medium is housed in a part of the human head. An excellent wearing feeling can be obtained.

In the above-mentioned Examples 1 to 10, the cooling medium 8 cooled to about −20 ° C. was used, but the cooling medium 8 cooled to a desired temperature can be used without being limited thereto. In this case, a “comfortable wearing time” due to the cooling temperature is obtained.
For example, when a head cooling tool containing a cooling medium 8 cooled to about −5 ° C. to 0 ° C. is attached to the human head, a comfortable cooling feeling with a feeling of over-cooling is obtained from the time of wearing. It is done.

<Measurement results when the head cooling device is mounted upside down>
In the measurement results of Table 2, when the head cooling device of Example 3 was mounted upside down, the “comfortable wearing time” increased from 90 minutes to 150 minutes compared to the case of normal wearing alone. When the head cooling tool of Example 4 was mounted upside down, the “comfortable wearing time” increased from 120 minutes to 165 minutes compared to the case of normal wearing alone. When the head cooling tool of Example 6 was mounted upside down, the “comfortable wearing time” was longer from 165 minutes to 180 minutes compared to the case of normal wearing alone. When the head cooling tool of Example 7 was turned upside down, the “comfortable wearing time” increased from 105 minutes to 165 minutes as compared with the case of normal wearing alone.
Thus, when the cooling medium is too cold below 0 ° C., the head cooling tool is turned over and attached to the human head, and then when the cooling temperature reaches a comfortable cooling temperature (about 5 to 7 degrees), When the head cooling device was returned to the front and normally attached to the human head, the “comfortable wearing time” was about 15 to 60 minutes longer.

That is, the prepared sealed cooling medium 8 is cooled in a refrigerator at about −10 ° C., and the sealed cooling medium 8 is stored in each storage section 4 of each head cooling tool. These head cooling tools are mounted on the human head in a place where the air conditioner wind of about 25 ° C. is not applied, and the surface temperature of the sheet-like member on the inner surface side where the respective sealed cooling medium 8 is stored is determined. It measures with the surface thermometer (infrared radiation thermometer ISK-8700II) for every elapsed time.

The “comfortable wearing time” when the surface temperature of the sheet-like member is “about 2 ° C. to about 15 ° C.” is about 75 minutes.

<About the measurement result of Example 4b>
In the head cooling device of Example 4b in which the sheet-like head protection member 7 is configured on the inner surface side of the head cooling device of Example 3, the “comfort wearing time” is about 120 minutes. That is, by installing the sheet-like head protection member 7 between the human head and the cooling medium, the temperature of the cooling medium that reaches the human head is reduced to a comfortable temperature range, “Time” can be long. In the case where the sheet-like head protecting member 7 of the present embodiment is configured, the temperature reaching the human head is lowered by about 4 to 5 ° C. by interposing the sheet-like head protecting 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 5b>
In the head cooling tool of Example 5b in which the material having the same heat insulating property as the sheet-shaped surface member configured in the head cooling tool of Example 3 is configured as the sheet-shaped inner surface member, the “comfort wearing time” is 210 minutes. . That is, a material having high heat insulation performance is used as a constituent material for both the sheet-like surface member and the sheet-like inner surface member, and the cooling medium is housed in the housing portion having the high heat insulation property. Reducing the temperature of the cooling medium that has reached too low to a comfortable temperature range can prolong the “comfort wearing time”, and further reduce the temperature rise rate of the cooling medium to reduce the “comfort wearing time”. Can be long.

<About the measurement result of Example 6b>
The sheet-like surface member 2 constitutes a heat-insulating material that does not contain a metal thin film, the sheet-like inner surface 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 surface member 3.

Can be relaxed to a comfortable temperature range, and the “comfort wearing time” can be made longer, and further, the temperature increase rate of the cooling medium can be slowed to make the “comfort wearing time” longer. However, when compared with the head cooling device of Example 4 in which the sheet-like surface member 2 has better heat insulation performance than the present example, the “comfort wearing time” tends to be slightly shorter.

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

<About the measurement result of Example 9b>
