DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Exemplary embodiments will now be described in detail with reference to the accompanying drawings, in which: Fig. 1 is a plan view of a cooling tool 100 when not in use; Fig. 2 is a schematic diagram showing the cooling tool 100 when in use;

[0010] The cooling device 100 is used to cool the head 8 of a human body. The cooling device 100 is placed inside a hat 9. The hat 9 has a crown 91 and a slider 92 attached to the inside of the crown 91 at the lower end of the crown 91. The slider is also called a bottle skin. The cooling device 100 comprises a cooling device main body 1 for cooling the head 8, and a sheet-like insert piece 15 inserted into the gap between the crown 91 and the slider 92 (hereinafter simply referred to as "the gap of the hat 9"). The cooling device 100 may further comprise an attachment 7 for attaching the cooling device 100 to the hat 9.

[0011] The cooling tool body 1 has flexibility. The cooling tool body 1 is formed in a plate shape. In this example, the shape of the cooling tool body 1 is a circle with a plurality of cuts 6, which will be described later. The cooling tool body 1 can be transformed into a first state in a plate shape and a second state in a curved shape. The curved shape in the second state can be a cup shape, a bowl shape, a bell shape, or a spherical crown shape. The first state is a state when the cooling tool 100 is not in use, and the second state is a state when the cooling tool 100 is in use. In the following description, unless otherwise specified, the cooling tool body 1 in the first state will be described. In this example, a vent hole 12 is formed at approximately the center of the cooling tool body 1. The vent hole 12 penetrates the cooling tool body 1 in the thickness direction.

[0012] More specifically, the cooling device main body 1 has a cooling agent 2 and an exterior pack 3 for accommodating the cooling agent 2 therein.

[0013] The ice pack 2 is a PCM (Phase Change Material) that absorbs heat and changes from a solid phase to a liquid phase. The ice pack 2 includes, for example, an aliphatic hydrocarbon. The aliphatic hydrocarbon is, for example, paraffin or an aliphatic saturated hydrocarbon. The ice pack 2 includes, for example, tetradecane (C 14 H 30 ), hexadecane (C 16 H 34 ) and octadecane (C 18 H 38) The ice pack 2 may contain only one or only two of tetradecane, hexadecane, and octadecane, or may contain all of them. In addition to aliphatic hydrocarbons, the ice pack 2 may further contain a super absorbent polymer (SAP), water, aroma, graphite, organic matter, or minerals. The melting point of the ice pack 2 is, for example, room temperature. The melting point of the ice pack 2 is preferably 5°C or higher and 35°C or lower, and more preferably 15°C or higher and 35°C or lower. When in the solid phase and liquid phase, the ice pack 2 absorbs the heat of the human body as sensible heat. When changing from the solid phase to the liquid phase, the ice pack 2 absorbs the heat of the human body as latent heat, specifically, heat of fusion.

[0014] The exterior pack 3 has flexibility and is formed from one or a mixture of resins such as thermoplastic polyurethane (TPU), nylon, polyvinyl chloride (PVC), polyethylene (PE), and polypropylene (PP).

[0015] Specifically, the exterior pack 3 includes a plurality of storage sections 32 that individually store the ice packs 2. The exterior pack 3 further includes a peripheral portion 31 and a partition portion 33 that divides the internal space into a plurality of storage sections 32. For ease of explanation, the plurality of storage sections 32 are indicated by dots in Fig. 1. The same applies to Figs. 3, 4, 5, 7, and 8 described below.

[0016] Each of the plurality of storage sections 32 is sealed. That is, the ice pack 2 is stored in each storage section 32 individually. In this example, each of the plurality of storage sections 32 has a substantially trapezoidal or substantially fan-shaped planar shape. In the approximate center of the cooling device main body 1, four substantially fan-shaped storage sections 32 are arranged radially with the vent hole 12 as the center. Fifteen substantially trapezoidal storage sections 32 are arranged radially around the four substantially fan-shaped storage sections 32. When the cooling device 100 is in use, the plurality of storage sections 32 come into contact with the frontal region 81, the back of the head 82, the top of the head 83, and the sides of the head 84 of the human body, and cool the head 8.

[0017] Fig. 3 is a cross-sectional view of the cooling device 100 taken along line III-III in Fig. 1. The exterior pack 3 is formed by overlapping and bonding two sheets together. Specifically, the exterior pack 3 is formed by bonding a first sheet 41 and a second sheet 42 that face each other in the thickness direction to each other.

[0018] The first sheet 41 is flat. On the other hand, the second sheet 42 has a plurality of recesses 42a recessed in the opposite direction to the first sheet 41. Each recess 42a is closed by the first sheet 41. The first sheet 41 and the second sheet 42 are joined to each other so that each recess 42a is sealed by the first sheet 41. Specifically, the portion of the second sheet 42 excluding the recesses 42a, that is, the outer periphery of the second sheet 42 and the portion between the adjacent recesses 42a, are joined to the first sheet 41. The joining of the first sheet 41 and the second sheet 42 is realized by, for example, heat welding. In FIG. 3, the boundary of the joined portion in the outer pack 3 is shown by a solid line, but in reality, the boundary of the joined portion does not have to be clearly visible. The peripheral portion 31 is formed by joining the peripheral portion of the first sheet 41 and the peripheral portion of the second sheet 42. The storage portion 32 is formed by the recesses 42a and the first sheet 41. The partition portion 33 is formed by joining a portion of the second sheet 42 between adjacent recesses 42a and the first sheet 41.

[0019] As shown in FIG. 1, the cooling tool body 1 is formed with a plurality of notches 6 extending inward from an outer peripheral edge 19 of the cooling tool body 1. The outer peripheral edge 19 of the cooling tool body 1 is a contour line that defines the overall shape of a collection of a plurality of storage sections 32. In FIG. 1, for convenience of explanation, the outer peripheral edge 19 is drawn by a two-dot chain line. Each notch 6 extends from the outer peripheral edge 19 toward the radially inward direction of the cooling tool body 1. Each notch 6 has a width that increases from the inside of the cooling tool body 1 toward the outer peripheral edge 19 in the extending direction of the notch 6. Each notch 6 is formed in a roughly wedge shape. Six of the plurality of notches 6 are formed at equal intervals in a direction along the outer peripheral edge 19.

[0020] In this example, the tip of the notch 6 on the opposite side to the outer peripheral edge 19 is disposed between two substantially trapezoidal storage portions 32 adjacent in the direction along the outer peripheral edge 19. In other words, the notch 6 extends from the outer peripheral edge 19 to a position between two substantially trapezoidal storage portions 32 adjacent in the direction along the outer peripheral edge 19.

[0021] The insertion piece 15 is a portion of the cooling tool 100 that is formed on the outer peripheral edge 19 of the cooling tool body 1, and has a maximum thickness that is thinner than the maximum thickness of the cooling tool body 1 by a predetermined amount or more. The insertion piece 15 is disposed on the outer peripheral edge 19 of the cooling tool body 1. In this example, the insertion piece 15 is disposed between two adjacent notches 6 in the direction along the outer peripheral edge 19. That is, in this example, the insertion piece 15 is divided in the direction along the outer peripheral edge 19. In this example, the insertion piece 15 is disposed on a part of the outer peripheral edge 19. In this example, the insertion piece 15 does not include a cooling agent 2.

[0022] As shown in Fig. 3, in this example, the insertion piece 15 includes a peripheral portion 31 of the outer pack 3 and a plate-shaped (specifically, flat) insertion piece body 18. The insertion piece body 18 is formed in a fan shape with a notched center when viewed from above. The insertion piece body 18 extends from the outer peripheral edge 19 to a position outside the outer peripheral edge of the peripheral portion 31. The insertion piece body 18 is attached to the bottom surface of the peripheral portion 31 by, for example, an adhesive. The insertion piece body 18 may also be attached to the top surface of the peripheral portion 31.

[0023] The insert piece body 18 is made of, for example, resin. The material of the insert piece body 18 may be the same as the material of the outer pack 3, or may be different from the material of the outer pack 3. The insert piece body 18 may be made of a material having flexibility, or may be made of a material having high rigidity.

[0024] The thickness t1 of the insertion piece 15 is thinner than the thickness t2 of the storage section 32 (i.e., the thickness of the cooling device main body 1). The thickness t1 is preferably one-third or less of the thickness t2, more preferably one-quarter or less of the thickness t2, and even more preferably one-fifth or less of the thickness t2. When the thickness t1 is non-uniform as in this example, the thickness t1 may be the maximum thickness. Similarly, when the bottom surface of the recess 42a in the storage section 32 is not flat, the thickness t2 may be the maximum thickness.

[0025] As shown in FIG. 1, the insertion piece 15 extends from the outermost storage portion 32 to the outside of the cooling tool main body 1. The insertion piece 15 has a length L in a direction perpendicular to the outer peripheral edge 19 (specifically, a direction perpendicular to the direction along the outer peripheral edge 19). In this example, the direction perpendicular to the outer peripheral edge 19 coincides with the radial direction of the cooling tool main body 1. The length L is the length from the outer peripheral edge 19 to the outer peripheral edge of the insertion piece 15. The length L is 25 mm or more. The length L is preferably 30 mm or more, more preferably 33 mm or more, even more preferably 36 mm or more, and even more preferably 40 mm or more. In this example, the length of the insertion piece 15 in the direction perpendicular to the outer peripheral edge 19 is constant in the direction along the outer peripheral edge 19. In addition, if the length of the insertion piece 15 in the direction perpendicular to the outer peripheral edge 19 is not constant in the direction along the outer peripheral edge 19, the above-mentioned length L may be the maximum length of the length of the insertion piece 15 in the direction perpendicular to the outer peripheral edge 19 at any point on the outer peripheral edge 19.

[0026] Fig. 4 is a cross-sectional view of the cap 9 showing the insertion piece 15 being inserted into the gap in the cap 9. Specifically, Fig. 4 is a cross-sectional view of the cap 9 cut along a plane perpendicular to the lower edge of the crown 91. As described above, the insertion piece 15 is inserted into the gap in the cap 9.

[0027] Here, the width of the sweatband of the hat will be explained. The sweatband width is the length in the direction perpendicular to the direction in which the sweatband extends (hereinafter referred to as the "width direction"). Tables 1 to 6 below are tables summarizing the widths of common sweatbands available on the market. Specifically, Table 1 below is a list of sweatband widths available at Ikegami Hat Workshop (reference website: https: / / ikegami-boushi.com / about_sweatband / ).

[0031] [Table 4]

[0032] [Table 5]

[0033] [Table 6]

[0034] As shown in Tables 1 to 6, the width of the slider generally distributed on the market is 25 mm or more. If the width of the slider is less than 25 mm, the slider function such as sweat absorption may be impaired. As shown in FIG. 4, in a general hat 9, the end of the slider 92 in the width direction is sewn to the lower end of the crown 91. Therefore, the depth of the gap in the hat 9 is approximately the same as the width W of the slider 92 or is smaller than the width W of the slider 92. Therefore, in a cooling tool 100 in which the length L of the insert piece 15 is 25 mm or more, only the insert piece 15 of the cooling tool main body 1 and the insert piece 15 is inserted into the gap in the hat 9. That is, in the cooling tool 100, the storage section 32 of the cooling tool main body 1 is not inserted into the gap in the hat 9.

[0035] As shown in FIG. 1, the attachment 7 is attached to the cooling tool main body 1 or the insertion piece 15. In this example, the attachment 7 is attached to the cooling tool main body 1. More specifically, the attachment 7 is attached to a portion of the outer periphery 19 where the insertion piece 15 is not arranged. The attachment 7 extends linearly. In the attachment 7, a first end 75 in the extending direction is attached to the outer periphery 19. The attachment 7 has a first button 71 arranged at the first end 75 and a second button 72 arranged at a second end 76 opposite to the first end 75. The attachment 7 is attached to the hat 9 in a ring shape. In this example, the portion of the periphery 31 of the exterior pack 3 where the attachment 7 is attached is not inserted into the gap of the hat 9 and is not included in the insertion piece 15. In other words, this portion is a part of the cooling tool main body 1.

[0036] FIG. 5 is a bottom view of the hat 9 on which the cooling tool 100 is installed. For convenience of explanation, the mounting tool 7 is omitted in FIG. 5. In this example, the hat 9 is a bucket hat. When the cooling tool 100 is installed inside the hat 9, the two adjacent storage sections 32 are brought close to each other across the notch 6 or are overlapped, thereby transforming the cooling tool main body 1 from the first state to the second state. As a result, the cooling tool main body 1 has a shape that conforms to the shape of the user's head 8. Next, the cooling tool 100 with the cooling tool main body 1 transformed to the second state is inserted inside the hat 9. At this time, the cooling tool 100 is inserted inside the hat 9 so that the first sheet 41 of the first sheet 41 and the second sheet 42 of the exterior pack 3 faces the crown 91. That is, the cooling tool 100 is inserted inside the hat 9 so that the second sheet 42 of the exterior pack 3 comes into contact with the head 8 when the user wears the hat 9. Next, the insertion piece 15 is inserted into the gap of the hat 9. As a result, the cooling device 100 is placed inside the hat 9. The user can cool the head 8 by wearing the hat 9 with the cooling device 100 placed thereon.

[0037] 6 is a perspective view of the hat 9 on which the cooling tool 100 is installed. In this example, the hat 9 is a baseball cap. After the cooling tool 100 is installed inside the hat 9, the cooling tool 100 may be attached to the hat 9 using the attachment tool 7. In detail, after the attachment tool 7 is wound around, for example, a size adjustment belt 95 of the hat 9, the second button 72 is fitted into the first button 71. In other words, the attachment tool 7 is fastened to the size adjustment belt 95. The cooling tool 100 may be attached to the hat 9 in this manner.

[0038] According to such a cooling tool 100, the sheet-like insert piece 15 is inserted into the gap of the hat 9, and the cooling tool 100 is installed inside the hat 9. Furthermore, since the length L of the insert piece 15 is 25 mm or more, only the insert piece 15 of the cooling tool main body 1 and the insert piece 15 is inserted into the gap of the hat 9. That is, the thick storage section 32 of the cooling tool main body 1 is not inserted into the gap of the hat 9. Therefore, when the cooling tool 100 is installed inside the hat 9, the expansion of the gap of the hat 9 due to the insertion of a part of the cooling tool 100 is suppressed, and the size of the hat 9 can be suppressed from becoming small. As a result, the problem that the cooling tool 100 is installed inside the hat 9 and makes it difficult to wear the hat 9 can be solved. In detail, the size of the hat 9 depends on the inner diameter of the slider 92. If the thick storage section 32 enters the gap of the hat 9, the size of the hat 9 becomes small, and there is a risk that it becomes difficult to wear the hat 9. In the cooling tool 100, the thin insertion piece 15 is inserted into the gap in the hat 9, and the thick storage part 32 is not inserted into the gap in the hat 9, so that the problem of the hat 9 being difficult to put on can be eliminated.

[0039] Moreover, by making the length L of the insertion piece 15 30 mm or more, it becomes easier to realize a state in which only the insertion piece 15 is inserted without the storage portion 32 being inserted into the gap of the cap 9, and since the distance between the storage portion 32 and the slider 92 is not so far, the lower part of the head 8 can be sufficiently cooled. Moreover, the median value of the slider width shown in Tables 1 to 6 is approximately 33 mm. Therefore, by making the length L of the insertion piece 15 33 mm or more, it becomes easier to realize a state in which only the insertion piece 15 is inserted without the storage portion 32 being inserted into the gap of the cap 9 for most of the caps 9 distributed on the market. Moreover, by making the length L of the insertion piece 15 36 mm or more, it becomes even easier to realize a state in which only the insertion piece 15 is inserted without the storage portion 32 being inserted into the gap of the cap 9 for most of the caps 9 distributed on the market. Moreover, the maximum value of the slider width shown in Tables 1 to 6 is approximately 40 mm. Therefore, by making the length L of the insertion piece 15 40 mm or more, it becomes easier to achieve a state in which only the insertion piece 15 is inserted without the storage section 32 being inserted into the gap of the hat 9 for most hats 9 available on the market.

[0040] Also, the cooling tool body 1 is formed with a slit 6. This allows the cooling tool body 1 to be deformed into a second state of a curved shape along the head 8 when the cooling tool 100 is in use. As a result, the head 8 can be cooled efficiently. Furthermore, since the insertion piece 15 is disposed between two adjacent slits 6 in the direction along the outer peripheral edge 19, the cooling tool body 1 can be deformed from the first state to the second state without being hindered by the insertion piece 15. That is, even when the insertion piece 15 is formed in the cooling tool body 1, the cooling tool body 1 can be easily deformed from the first state to the second state.

[0041] Furthermore, since the cooling tool 100 is provided with the attachment tool 7, it is possible to prevent the cooling tool 100 from falling off the hat 9. Particularly in this example, the attachment tool 7 is attached to a portion of the outer circumferential edge 19 of the cooling tool main body 1 where the insertion piece 15 is not disposed. As a result, the attachment tool 7 does not impede the insertion piece 15 from being inserted into the gap in the hat 9, so even with the cooling tool 100 having the attachment tool 7, the insertion piece 15 can be easily inserted into the gap in the hat 9, and it is possible to prevent the cooling tool 100 from falling off the hat 9.

[0042] Next, a cooling tool 200 according to a modified example will be described. The basic configuration of the cooling tool 200 is the same as that of the cooling tool 100. Therefore, the following description will focus on the differences from the cooling tool 100.

[0043] FIG. 7 is a plan view of a cooling tool 200 according to a modified example. FIG. 8 is a cross-sectional view of the cooling tool 200 taken along line VIII-VIII in FIG. 7. In FIG. 7, for convenience of explanation, the outer peripheral edge 19 of the cooling tool main body 201 is drawn by a two-dot chain line. The cooling tool 200 differs from the cooling tool 100 in that the insert piece 215 is integrally and continuously formed with the cooling tool main body 201. That is, in this example, the insert piece 215 is a part of the exterior pack 203. More specifically, the insert piece 215 is formed by the peripheral portion 231 of the exterior pack 203. The insert piece 215 has the above-mentioned length L. The length L is 25 mm or more. The insert piece 215 does not include the ice pack 2. In this example, the insert piece 215 is formed around the entire outer peripheral edge 19. The cooling device 200 eliminates the need to attach the insert piece body to the outer pack 203 using adhesive or the like, and therefore the cooling device 200 having the insert piece 215 can be easily manufactured.

[0044] Other Embodiments As described above, the above embodiment has been described as an example of the technology disclosed in this application. However, the technology in this disclosure is not limited to this, and can be applied to embodiments in which modifications, replacements, additions, omissions, etc. are appropriately performed. In addition, it is also possible to combine the components described in the above embodiment to form a new embodiment. In addition, among the components described in the attached drawings and detailed description, not only components essential for solving the problem but also components that are not essential for solving the problem in order to exemplify the technology may be included. Therefore, the fact that these non-essential components are described in the attached drawings and detailed description should not immediately be taken to mean that these non-essential components are essential.

[0045] There is no limitation on the shape of the cooling tool main body 1, 201. The shape of the cooling tool main body 1, 201 may be a polygon such as a rectangle. There is no limitation on the shape, number and arrangement of each of the multiple storage sections 32.

[0046] The shape of the insert piece 15, 215 is not limited. The length of the insert piece 15, 215 in the direction perpendicular to the outer peripheral edge 19 does not have to be constant in the direction along the outer peripheral edge 19. The insert piece 15, 215 can be disposed at any position on the outer peripheral edge 19 of the cooling device body 1.

[0047] The first sheet 41 does not have to be flat. The first sheet 41 may have a plurality of recesses formed therein that are recessed in a direction opposite to the second sheet 42. In this case, the partition portion 33 may be formed by joining a portion between adjacent recesses 42a of the second sheet 42 and a portion between adjacent recesses of the first sheet 41.

[0048] The shape, number and arrangement of the notches 6 are not limited. The shape of the notches 6 may be a polygon or a curved shape. The notches 6 may be linear. Specifically, the notches 6 may be formed by cutting the exterior pack 3 linearly. The number of notches 6 may be one, or two or more. The notches 6 may be arranged at any position on the outer circumferential edge 19 of the cooling device main body 1.

[0049] The shape, number and arrangement of the mounting fixtures 7 are not limited. Two or more mounting fixtures 7 may be attached to the cooling tool body 1 or the insertion piece 15. The mounting fixtures 7 may be attached to any position of the cooling tool body 1. The mounting fixtures 7 may be attached to the insertion piece 15. Furthermore, the mounting fixtures 7 may not be attached to the cooling tool 100.

[0050] The technology of the present disclosure can be summarized as follows.

[0051] [1] A cooling device 100,200 is a cooling device 100,200 to be placed inside a hat 9 having a crown 91 and a slider 92 attached to the inside of the crown 91 at the lower end thereof, and comprises a plate-shaped cooling device main body 1 for cooling a head 8, and a sheet-shaped insert piece 15,215 arranged on an outer peripheral edge 19 of the cooling device main body 1 and inserted into a gap between the crown 91 and the slider 92, the cooling device main body 1 has an ice pack 2 and an outer pack 3 for containing the ice pack 2, and a length L of the insert piece 15,215 in a direction perpendicular to the outer peripheral edge 19 is 25 mm or more.

[0052] According to this configuration, the sheet-like insert piece 15,215 is inserted into the gap between the crown 91 and the slider 92, and the cooling tool 100 is installed inside the hat 9. Furthermore, since the length L of the insert piece 15,215 is 25 mm or more, only the insert piece 15,215 of the cooling tool main body 1 and the insert piece 15,215 is inserted into the gap. That is, the thick cooling tool main body 1 is not inserted into the gap. Therefore, when the cooling tool 100 is installed inside the hat 9, the expansion of the gap caused by the insertion of a part of the cooling tool 100 is suppressed, and the size of the hat 9 is suppressed from becoming small. As a result, the problem that the cooling tool 100 is installed inside the hat 9 and makes it difficult to wear the hat 9 can be solved. In detail, the size of the hat 9 depends on the inner diameter of the slider 92. If the thick cooling tool main body 1 enters the gap, the size of the hat 9 becomes small, and there is a risk that the size of the hat 9 becomes difficult to wear. In the cooling tool 100, the thin insertion pieces 15, 215 are inserted into the gaps described above, and the thick cooling tool main body 1 is not inserted into the gaps described above, so that the difficulty in putting on the hat 9 can be eliminated.

[0053] [2] In the cooling device 100, 200 described in [1], the length L of the insertion piece 15, 215 is 33 mm or more.

[0054] The median width of the slider 92 of the cap 9 is approximately 33 mm. For this reason, by making the length L of the insertion piece 15, 215 33 mm or more, it becomes easier to realize a state in which only the insertion piece 15, 215 is inserted into the above-mentioned gap without the cooling tool main body 1 being inserted into the gap for most caps 9 available on the market.

[0055] [3] In the cooling device 100, 200 described in [1] or [2], the length L of the insertion piece 15, 215 is 40 mm or more.

[0056] The maximum width of the slider 92 of the cap 9 is approximately 40 mm. For this reason, by making the length L of the insertion piece 15, 215 40 mm or more, it becomes easier to realize a state in which only the insertion piece 15, 215 is inserted into the above-mentioned gap without the cooling tool main body 1 being inserted into the gap for most caps 9 available on the market.

[0057] [4] In the cooling device (100, 200) according to any one of [1] to [3], the insert (15, 215) does not include a cooling agent.

[0058] According to this configuration, the thickness of the insertion pieces 15, 215 can be effectively reduced, so that when the cooling tool 100 is placed inside the hat 9, the above-mentioned bulging of the gap caused by the insertion of a part of the cooling tool 100 is further suppressed, and the size of the hat 9 is further prevented from becoming smaller. As a result, the problem of the cooling tool 100 being placed inside the hat 9 making it difficult to wear the hat 9 can be further prevented.

[0059] [5] In the cooling device 100, 200 described in any one of [1] to [4], the cooling device main body 1 is formed with a plurality of notches 6 extending inward from the outer peripheral edge 19, and the insertion piece 15, 215 is positioned between two adjacent notches 6 in a direction along the outer peripheral edge 19.

[0060] According to this configuration, since the cuts 6 are formed in the cooling tool main body 1,201, the cooling tool main body 1,201 can be deformed into a curved shape that conforms to the head 8 when the cooling tool 100, 200 is in use. As a result, the head 8 can be cooled efficiently. Furthermore, since the insertion pieces 15,215 are disposed between two adjacent cuts 6 in the direction along the outer peripheral edge 19, when the cooling tool main body 1,201 is deformed, the insertion pieces 15,215 are prevented from hindering the deformation. In other words, even if the insertion pieces 15,215 are formed in the cooling tool main body 1,201, the cooling tool main body 1,201 can be easily deformed.

[0061] [6] The cooling device 100 according to any one of [1] to [5], further comprising an attachment device 7 attached to the cooling device main body 1 or the insertion piece 15 for attaching the cooling device 100 to the hat 9.

[0062] According to this configuration, the cooling tool 100 can be prevented from falling off the hat 9.

[0063] [7] In the cooling tool 100 described in any one of [1] to [6], the insertion piece 15 is arranged on a part of the outer peripheral edge 19 of the cooling tool main body 1, and the mounting device 7 is attached to a part of the outer peripheral edge 19 where the insertion piece 15 is not arranged.

[0064] According to this configuration, the mounting fixture 7 does not hinder the insertion of the insertion piece 15 into the gap between the crown 91 and the slider 92, so that even in a cooling tool 100 having the mounting fixture 7, the insertion piece 15 can be easily inserted into the aforementioned gap, and the cooling tool 100 can be prevented from falling off the hat 9.
