(1) First embodiment:
The neck cooling band 100 as a cooling tool is capable of storing therein a cooling body filled with a coolant, and is wrapped around the user's neck by winding the neck around the user's neck and fastening the ends to each other. The user's neck can be cooled while maintaining

  FIG. 1 is a top view of a neck cooling band 100 according to the present invention, FIG. 2 is a bottom view of the neck cooling band 100 according to the present invention, and FIG. 3 is a perspective view of the neck cooling band 100 according to the present invention. FIG.

  As shown in these drawings, the neck cooling band 100 has a belt-like shape, and is provided with a cold insulator storage unit 10 for storing the cold insulators c1 to c4, and detachable from each other provided at the left and right ends of the cold insulator storage unit 10. And a pair of male and female hook-and-loop fasteners as the first fastening portions 11a and 11b.

  The cold insulator storage unit 10 has a plurality of bag-like parts 12 to 15 formed by partitions provided at predetermined intervals. A partition is realizable by sewing between the bag-shaped parts 12-15 with a fiber, for example, when forming the cold insulator storage part 10 with a cloth-like material.

  In the present embodiment, the number of the bag-like portions 12 to 15 is four. However, the number is not limited to this, and may be 5 or more, or 3 or less. However, when the cold insulators c1 to c4 do not have flexibility at the time of cooling, it is preferable to have at least four bag-shaped portions in order to wrap around the neck.

  Increasing the number of bag-like parts makes it easier to wrap the neck cooling band 100 around the neck, and conversely, if the number of bag-like parts is reduced, storage and removal of the cold insulator in the bag-like part during use is possible. Less time and effort

  The cold insulator storage unit 10 has a bag shape with an upper edge 10a opened, and is configured to store the cold insulators c1 to c4 therein. In this opening, lid portions 12a to 15a are provided to prevent the cold insulators c1 to c4 stored in the cold insulator storage portion 10 from popping out.

  The lid portions 12a to 15a are formed by extending one edge of the opening and folding back so as to cover the other edge. The length of the folded portion is 1/4 to 1/2 of the width of the neck cooling band 100, for example, about 1/3. Both ends of the lid portions 12a to 15a in the longitudinal direction of the neck cooling band 100 are fixed to the surface of the cold insulator housing portion 10 by, for example, sewing.

  When the cold insulators c1 to c4 are stored in the bag-like parts 12 to 15, the central part of the lid parts 12a to 15a is lifted to expose a part of the opening at the upper edge of the neck cooling band 100, and the cold is kept from the gap. The bodies c1 to c4 are inserted into the bag-like parts 12 to 15 and stored.

  The cold insulator storage unit 10 is formed of a flexible material, for example, plant fibers such as cotton, hemp, and linen, animal fibers such as wool, silk, and cashmere, regenerated fibers such as regenerated cellulose, polyester, and nylon Synthetic fibers such as, non-woven fabrics and the like can be used.

  Moreover, you may form the raw material of the cooler body accommodating part 10 using the raw material which can be expanded-contracted in a longitudinal direction. By forming the cold insulator storage portion 10 with such a material that is stretchable in the longitudinal direction, it is possible to improve the fit of the user around the neck.

  Moreover, it is preferable to form the raw material of the cool body storage part 10 using the raw material which is elastic also in a transversal direction (width direction). By having elasticity in the short direction, the cold insulators c1 to c4 can be easily stored.

Next, the fastening portion will be described.
A pair of male and female hook-and-loop fasteners 11a1 and 11b1 are attached to the fastening portions 11a and 11b, respectively. A pair of male and female hook-and-loop fasteners 11a1 and 11b1 are attached to the opposite surfaces of the fastening portion 11a and the fastening portion 11b. In FIGS. 1 to 3, the hook-and-loop fastener 11a1 is on the bottom side (back surface) of the fastening portion 11a. The hook-and-loop fastener 11b1 is attached to the upper surface side (front surface side) of the fastening portion 11b.

  Thus, by making the attachment surface of the surface fastener opposite to the front and back at the fastening portions 11a and 11b, the male surface fastener and the female surface fastener are opposed to each other when the neck cooling band 100 is wound around the neck. The fastening portions 11a and 11b can be fastened. Thereby, as shown in FIGS. 6 and 7, which will be described later, when the neck cooling band 100 is attached around the neck of the user, it can be performed easily and visually.

  Further, at least one of the male surface fastener and the female surface fastener is formed in a longitudinal shape in the longitudinal direction of the neck cooling band 100, and is configured to be able to cope with individual differences in the length around the neck. In the example shown in FIG. 2, the hook-and-loop fastener 11a1 is formed longer in the longitudinal direction of the neck cooling band 100 than the hook-and-loop fastener 11b1.

  The fastening means provided in the fastening parts 11a and 11b is not limited to a hook-and-loop fastener, but may be any detachable structure that can be easily operated by the user.

  The material for forming the fastening portions 11a and 11b is not particularly limited as long as it is a flexible material. For example, plant fiber materials such as cotton, hemp, and linen, animal fiber materials such as wool, silk, and cashmere, and regeneration. Recycled fiber materials such as cellulose, synthetic fiber materials such as polyester and nylon, and nonwoven fabrics can be used.

  Moreover, you may use a rubber-like raw material with a stretching property as a material which forms the fastening parts 11a and 11b. By forming the fastening portions 11a and 11b from a stretchable material, the length in the longitudinal direction of the neck cooling band 100 is suitably adjusted at the time of wearing, and the fit of the user around the neck is improved. Can do.

  Each bag-like part 12-15 accommodates the cold insulators c1-c4, respectively. The size of the cold insulators c1 to c4 is set to a size that can be stored in the bag-like portions 12 to 15. When the cold insulators c1 to c4 have little flexibility at the time of cooling, the cold insulators c1 to c4 are made a size slightly smaller than, for example, the bag-like portions 12 to 15.

  The cold insulators c1 to c4 are obtained by filling a bag made of polyester or the like with a cold insulator (cold storage agent) and sealing it. Various materials can be used as the material for the cold insulator as long as the material can be stored by cooling in a freezer or the like.

  For example, as the cooling agent, a highly water-absorbing polymer that has absorbed water can be used. As a more specific example, 20% to 25% water-absorbing polymer, 75 to 80% water, and 0.01% fungicide were adjusted to 100% as a whole by weight%. A cryogen is preferably used.

  FIG. 4 is a table and a graph showing the test results of the cooling capacity of the cooling agent whose components are adjusted at the above-described ratios. The test results shown in the figure were performed under the following conditions.

[Test conditions]
(1) The cold insulator is placed in a -20 ° C incubator for 12 hours and cooled.
(2) Take out the cold insulator from the thermostat and quickly transfer it to a thermostat at 25 ° C.
(3) The test is started 3 minutes after the thermocouple is attached under the cold insulator, and the change in temperature with time is measured.
(4) The test is performed four times at different positions, and the average value of the data is taken as the test result.
(Temperature and humidity: 25 ± 2 ° C x 50 ± 5% RH, measurement interval: 1 minute, measurement time: 150 minutes)

  FIG. 5 is a photograph of the cold insulator used in the test of FIG. As shown in the figure, in the test of FIG. 4, considering the variation in product quality, the four cold insulators adjusted with the above-mentioned ratio of the cold-retaining agent are used as test samples, and each of them is subjected to the above test conditions. A test was conducted.

  As a result of the test, it was proved that all of the four cold insulators maintained below 15 ° C. even when 90 minutes passed from the start of the test, as shown in FIG. In general, it is said that the temperature difference from the outside air temperature needs to be 10 ° C. or more in order for the user to feel cold. That is, it can be seen that the cold insulators c1 to c4 filled with the cold-retaining agent adjusted at the above-described ratio satisfy this cooling sensation condition and have a very high cooling capacity.

  In addition, you may coat | cover the cold insulators c1-c4 with the heat insulation sheet which consists of an aluminum layer and a porous sheet layer. By using the cold insulators c1 to c4 covered with such a heat insulating sheet, it is possible to lengthen the duration of the cooling effect of the cryogen and to prevent the neck from being excessively cooled. .

  However, such a heat insulating sheet used for covering the cold insulators c1 to c4 does not completely block heat transfer, and uses a material capable of transferring heat to some extent between the cold insulator and the body surface. Is desirable.

  Moreover, it is preferable that the bag which wraps the cooling agent of the cold insulators c1 to c4 includes at least one layer containing pearl powder (hereinafter referred to as a pearl-containing layer). By wrapping the refrigeration agent in the pearl-containing layer, the cooling sensation duration of the refrigeration bodies c1 to c4 is remarkably longer than that of the refrigeration body used in the test of FIG. 4, as shown in FIGS. It was confirmed that

  FIGS. 6 and 7 are a table and a graph showing the test results of the cooling capacity of a cooling agent in which a pearl-containing layer is provided in a bag that wraps a cooling body while adjusting the components at the above-described ratios. The test results shown in the figure were performed under the following conditions.

[Test conditions]
(1) The cold insulator is placed in a -20 ° C incubator for 16 hours and cooled.
(2) Take out the cold insulator from the thermostat and quickly transfer it to a thermostat at 35 ° C.
(3) The test is started 3 minutes after the thermocouple is attached under the cold insulator, and the change in temperature with time is measured.
(4) The test is performed four times at different positions, and the average value of the data is taken as the test result.
(Temperature and humidity: 35 ± 2 ° C x 50 ± 5% RH, measurement interval: 1 minute, measurement time: 120 minutes)

  FIG. 8 is a photograph of the cold insulator used in the tests of FIGS. As shown in the figure, in the tests of FIGS. 6 and 7, the pearl-containing layer is formed in a bag that wraps the cooler while adjusting the components of the cooler at the above-mentioned ratio in consideration of variations in product quality. Two cold insulators provided with the above were used as test samples, and each was tested under the above test conditions.

  As a result of the test, as shown in FIGS. 6 and 7, it was proved that the two cold insulators both maintained below 25 ° C. even when 120 minutes passed from the start of the test. The test results shown in FIGS. 6 and 7 have a temperature difference of 10 ° C. or more from the outside temperature satisfying the cooling sensation even though the outside temperature is as high as 35 ° C. compared to the test shown in FIG. 4 described above. The state is maintained for 120 minutes or more. That is, it can be seen that the cooling capacity of the cold insulators c1 to c4 is dramatically improved by providing the pearl-containing layer on the bag that wraps the cold insulator.

  The cold insulator storage portion 10 has a curved shape as a whole, and the upper edge 10a and the lower edge 10b are formed in a substantially arc shape with a predetermined curvature different from each other.

The diameter of the circle formed by the side edge 10b is larger, and the neck cooling band 100 is expanded downward as shown in FIGS.

  More specifically, it is preferable that the radius of curvature of the upper edge 10a of the cold insulator storage unit 10 is about 380 to 410 mm, and the radius of curvature of the lower edge 10b of the cold insulator storage unit 10 is about 470 to 500 mm.

  In addition, the length of the upper edge 10a of the cool body storage portion 10 is approximately the same as the length around the neck at the narrowest position of the upper neck portion, and the length of the lower edge 10b of the cool body storage portion 10 is the length of the neck rear portion. It is preferable to have the same length as the length from the lower part (the position of the base of the neck) to the vicinity of the clavicle.

  Moreover, the cold insulator storage part 10 is formed in substantially the same width over the entire longitudinal direction according to the vertical length of the user's neck, and has a width of about 70 to 100 mm, for example.

  As described above, by adjusting the size of the cold insulator storage portion 10, the fastening portion 11a and the fastening portion 11b are fastened to each other, and the neck cooling band 100 is formed in a substantially cylindrical shape that is expanded downward. Further, the neck cooling band 100 fits suitably in the shape around the user's neck.

  That is, the cold insulator storage unit 10 in which the cold insulators c1 to c4 are stored covers the neck from the rear part around the user's neck to the vicinity of the collarbone in a natural manner. Thereby, while improving the cooling effect around the user's neck by the neck cooling band 100, it is possible to reduce the user's uncomfortable feeling due to wearing and to improve the aesthetics at the time of wearing.
