[Figure 4] 4 is a cross-sectional view of the cooling device taken along line IV-IV in FIG. [Figure 5] FIG. 5 is a perspective view of a cooling device according to a modified example. DETAILED DESCRIPTION OF THE INVENTION

[0009] FIG. 1 is a front view of the cooling device 100. FIG. 2 is a rear view of the cooling device 100. FIG. 3 is a side view of the cooling device 100. The cooling device 100 is worn on the torso 9 of a human body to cool the torso 9. In the following, the cooling device 100 will be described using the direction of the human body on which the cooling device 100 is worn. That is, the front of the human body on which the cooling device 100 is worn is referred to as the "front." The same applies to "rear," "left," "right," "top," and "bottom."

[0010] Cooling device 100 comprises a first cooling device 1 that forms the front body and is placed along the front of torso 9, and a second cooling device 2 that forms the back body and is placed along the back surface of torso 9. In this example, cooling device 100 further comprises shoulder straps 7 that connect first cooling device 1 and second cooling device 2. Cooling device 100 further comprises a torso strap 8 that connects first cooling device 1 and second cooling device 2.

[0011] Each of the first cooling tool 1 and the second cooling tool 2 is formed in a flat plate shape that extends in a direction intersecting the front-rear direction, more specifically, in a direction substantially perpendicular to the front-rear direction. That is, the thickness direction of each of the first cooling tool 1 and the second cooling tool 2 substantially coincides with the front-rear direction.

[0012] Fig. 4 is a cross-sectional view of the cooling device 100 taken along line IV-IV in Fig. 1. Each of the first cooling device 1 and the second cooling device 2 is formed by an ice pack 3 and a pack 4 that contains the ice pack 3.

[0013] The ice pack 3 is a PCM (Phase Change Material) that absorbs heat and changes from a solid phase to a liquid phase. The ice pack 3 includes, for example, an aliphatic hydrocarbon. The aliphatic hydrocarbon is, for example, paraffin or a saturated aliphatic hydrocarbon. The ice pack 3 includes, for example, tetradecane (C 14 H 30 ), hexadecane (C 16 H 34 ) and octadecane (C 18 H 38 ) The ice pack 3 may contain only one or two of tetradecane, hexadecane, and octadecane, or may contain all of them. In addition to aliphatic hydrocarbons, the ice pack 3 may further contain super absorbent polymer (SAP), water, aroma, graphite, organic matter, minerals, etc. The melting point of the ice pack 3 is, for example, room temperature. The melting point of the ice pack 3 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 and liquid phases, the ice pack 3 absorbs the heat of the human body as sensible heat. When changing from the solid phase to the liquid phase, the ice pack 3 absorbs the heat of the human body as latent heat, specifically, heat of fusion. The physical properties of the ice pack 3 of the first cooling device 1 and the ice pack 3 of the second cooling device 2 may be the same or different.

[0014] The pack 4 is flexible and is made of one or a mixture of resins such as thermoplastic polyurethane (TPU), nylon, polyvinyl chloride (PVC), polyethylene (PE), and polypropylene (PP).

[0015] The pack 4 has a plurality of storage chambers 43 that store ice packs 3. Each of the storage chambers 43 is sealed. That is, the ice packs 3 are stored individually in each storage chamber 43. The storage chambers 43 are lined up in a direction intersecting the front-to-rear direction. Specifically, the storage chambers 43 are lined up in the up-down direction and the left-to-right direction. In this example, the overall shape of the pack 4, the total number of storage chambers 43, and the shape of the storage chambers 43 differ between the first cooling device 1 and the second cooling device 2. The pack 4 of the first cooling device 1 has four rows of storage chambers 43 lined up in the left-to-right direction, each arranged in four columns in the up-to-down direction. The pack 4 of the second cooling device 2 has six rows of storage chambers 43 lined up in the left-to-right direction, each arranged in six columns in the up-to-down direction. The pack 4 may further be formed with a plurality of ventilation holes 44 that penetrate the pack 4 in the front-to-rear direction.

[0016] The pack 4 is formed by overlapping and joining two sheets. Specifically, the pack 4 has a first sheet 41 and a second sheet 42 that overlap in the front-to-rear direction. The outer periphery of the first sheet 41 overlaps with the outer periphery of the second sheet 42. The first cooling device 1 and the second cooling device 2 are arranged with their first sheets 41 facing each other.

[0017] The first sheet 41 is flat. On the other hand, the second sheet 42 has a plurality of recesses 42a recessed away from the first sheet 41. The opening of each recess 42a on the first sheet 41 side is blocked 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 portions of the second sheet 42 excluding the recesses 42a, i.e., the outer periphery of the second sheet 42 and the portions between adjacent recesses 42a, are joined to the first sheet 41. The joining of the first sheet 41 and the second sheet 42 is achieved, for example, by thermal welding. Note that in FIG. 4, the boundaries of the joined portions in the pack 4 are indicated by solid lines, but in reality, the boundaries of the joined portions do not need to be clearly visible. The storage chamber 43 is formed by the recesses 42a and the first sheet 41.

[0018] The shoulder straps 7 are worn over the shoulders of a person. In this example, the cooling device 100 has a pair of shoulder straps 7. The pair of shoulder straps 7 are spaced apart in the left-right direction. The shoulder straps 7 connect the upper part of the first cooling device 1 (more specifically, the upper end of the pack 4 of the first cooling device 1) to the upper part of the second cooling device 2 (more specifically, the upper end of the pack 4 of the second cooling device 2). The shoulder straps 7 may have a length adjuster 71 for adjusting the length of the shoulder straps 7. The length adjuster 71 is, for example, a ring, a buckle, or a hook-and-loop fastener. The same applies to the length adjuster 81 described below.

[0019] The waist straps 8 are placed around the torso 9. In this example, the cooling device 100 has a pair of waist straps 8. The pair of waist straps 8 are placed on the sides of the first cooling device 1 and the second cooling device 2. One waist strap 8 connects the left part of the first cooling device 1 (more specifically, the left end of the pack 4 of the first cooling device 1) to the left part of the second cooling device 2 (more specifically, the left end of the pack 4 of the second cooling device 2). The other waist strap 8 connects the right part of the first cooling device 1 (more specifically, the right end of the pack 4 of the first cooling device 1) to the right part of the second cooling device 2 (more specifically, the right end of the pack 4 of the second cooling device 2). The waist straps 8 may have a length adjuster 81 for adjusting the length of the waist straps 8.

[0020] The cooling device 100 is attached to the torso 9, for example, as shown below. That is, the user's head is passed between the first cooling device 1 and the second cooling device 2 and between the left and right shoulder straps 7 in that order, and is extended outside the cooling device 100. The user's left arm is passed between the left shoulder strap 7 and the left waist strap 8 and is extended outside the cooling device 100. The user's right arm is passed between the right shoulder strap 7 and the right waist strap 8 and is extended outside the cooling device 100. In this way, the cooling device 100 is attached to the torso 9. By attaching the cooling device 100 to the torso 9, the front of the torso 9 is cooled by the first cooling device 1, and the back of the torso is cooled by the second cooling device 2. The lengths of the shoulder straps 7 and the waist straps 8 are adjusted appropriately depending on the user's physique, etc.

[0021] Next, the configurations of the first cooling device 1 and the second cooling device 2 will be described in more detail. The lower end 12 of the first cooling device 1 is positioned below the upper end 21 of the second cooling device 2 and above the lower end 22 of the second cooling device 2. Here, the upper end 11 of the first cooling device 1 essentially refers to the uppermost end of the ice pack 3 in the first cooling device 1. For example, if the ice packs 3 are stored in multiple storage chambers 43 in the first cooling device 1, the uppermost end of the ice pack 3 stored in the uppermost storage chamber 43 is the upper end 11 of the first cooling device 1. The lower end 12 of the first cooling device 1 essentially refers to the lowermost end of the ice pack 3 in the first cooling device 1. For example, if the ice packs 3 are stored in multiple storage chambers 43 in the first cooling device 1, the lowermost end of the ice pack 3 stored in the lowermost storage chamber 43 is the lower end 12 of the first cooling device 1. The upper end 21 of the second cooling device 2 essentially means the uppermost end of the ice packs 3 in the second cooling device 2. For example, if the ice packs 3 are stored in multiple storage chambers 43 in the second cooling device 2, the uppermost end of the ice packs 3 stored in the uppermost storage chamber 43 is the upper end 21 of the second cooling device 2. The lower end 22 of the second cooling device 2 essentially means the uppermost end of the ice packs 3 in the second cooling device 2. For example, if the ice packs 3 are stored in multiple storage chambers 43 in the second cooling device 2, the lowermost end of the ice packs 3 stored in the lowermost storage chamber 43 is the lower end 22 of the second cooling device 2.

[0022] Specifically, the vertical dimension L1 of the first cooling device 1 (i.e., the distance from the upper end 11 to the lower end 12 in the vertical direction) is shorter than the vertical dimension L2 of the second cooling device 2 (i.e., the distance from the upper end 21 to the lower end 22 in the vertical direction). When the upper end 11 of the first cooling device 1 and the upper end 21 of the second cooling device 2 are located at the same height, the lower end 12 of the first cooling device 1 is located between the upper end 21 and the lower end 22 of the second cooling device 2 in the vertical direction. For example, the vertical dimension L1 of the first cooling device 1 is 2 / 3 or less of the vertical dimension L2 of the second cooling device 2. The vertical dimension L1 of the first cooling device 1 is 1 / 3 or more of the vertical dimension L2 of the second cooling device 2. The left-right dimension of the first cooling device 1 and the left-right dimension of the second cooling device 2 are approximately the same. The thickness of the first cooling device 1 and the thickness of the second cooling device 2 are approximately the same.

[0023] More specifically, the first cooling device 1 has a horizontally elongated shape. That is, the vertical dimension L1 of the first cooling device 1 is shorter than the horizontal dimension of the first cooling device 1. The second cooling device 2 has a vertically elongated shape. That is, the vertical dimension L2 of the second cooling device 2 is longer than the horizontal dimension of the second cooling device 2.

[0024] When the cooling device 100 is attached to the torso 9, the first cooling device 1 is placed on the chest 91, and the second cooling device 2 is placed on the back 93. Specifically, the first cooling device 1 is placed on the front of the torso 9 above the abdomen 92, but not on the abdomen 92. The second cooling device 2 is placed across the lower back (i.e., the waist) and upper back (i.e., the portion above the waist).

[0025] More specifically, the first sheet 41 of the first cooling device 1 fits along the chest 91. The second sheet 42 of the first cooling device 1 faces the opposite side from the chest 91. The first sheet 41 of the second cooling device 2 fits along the back 93. The second sheet 42 of the second cooling device 2 faces the opposite side from the back 93. The upper end 11 of the first cooling device 1 and the upper end 21 of the second cooling device 2 are positioned at approximately the same height. The lower end 12 of the first cooling device 1 is positioned below the upper end 21 of the second cooling device 2. The lower end 12 of the first cooling device 1 is positioned above the lower end 22 of the second cooling device 2. The lower end 12 of the first cooling device 1 is spaced above the lower end 22 of the second cooling device 2 by one-third or more of the vertical dimension L2 of the second cooling device 2. A portion of the ice pack 3 of the second cooling device 2 is positioned above the lower end 12 of the first cooling device 1. Another part of the ice pack 3 in the second cooling device 2 is located below the lower end 12 of the first cooling device 1.

[0026] Here, the lower end 12 of the first cooling device 1 is located higher than the lower end 22 of the second cooling device 2, and the first cooling device 1 is not placed on the abdomen 92. Therefore, the abdomen 92 is less likely to be cooled by the cooling device 100. Therefore, the torso 9 can be appropriately cooled while reducing cooling of the user's abdomen.

[0027] Furthermore, the lower end 12 of the first cooling device 1 is located above the lower end 22 of the second cooling device 2 by at least 1 / 3 of the vertical dimension L2 of the second cooling device 2. This further reduces the cooling of the belly 92 by the cooling device 100.

[0028] In addition, a portion of the ice pack 3 in the second cooling device 2 is positioned below the lower end 12 of the first cooling device 1. This allows the second cooling device 2 to cool the lower part of the back 93. This allows the cooling device 100 to further cool the torso 9 while reducing cooling of the user's abdomen.

[0029] In addition, a portion of the ice pack 3 in the second cooling device 2 is positioned above the lower end 12 of the first cooling device 1. Therefore, the second cooling device 2 can cool the part of the back above the waist. Therefore, the cooling device 100 can further cool the torso 9 while reducing cooling of the user's abdomen.

[0030] Furthermore, each pack 4 of the first cooling device 1 and the second cooling device 2 has a plurality of storage chambers 43 arranged at intervals, and no ice packs 3 are present in the portions of the pack 4 between adjacent storage chambers 43. As a result, the portions of the pack 4 between adjacent storage chambers 43 are more flexible than the storage chambers 43 containing ice packs 3. This allows each of the first cooling device 1 and the second cooling device 2 to easily deform to fit the shape of the body 9. As a result, the body 9 can be cooled even more effectively by the cooling device 100.

[0031] Next, a modified cooling tool 200 will be described. Fig. 5 is a perspective view of the modified cooling tool 200. The cooling tool 200 differs from the cooling tool 100 in that the first cooling tool 1 and the second cooling tool 2 are integrated. The basic configuration of the cooling tool 200 is the same as that of the cooling tool 100, so a description thereof will be omitted.

[0032] Cooling device 200 does not have a shoulder strap 7. The top of first cooling device 1 and the top of second cooling device 2 are connected. Specifically, the top end of pack 4 of first cooling device 1 and the top end of second cooling device 2 are continuous. This makes first cooling device 1 and second cooling device 2 integrated. The connecting portion of first cooling device 1 and second cooling device 2 is hung over the shoulder of the person, and cooling device 200 is worn on the torso 9.

[0033] In this example, the first cooling device 1 and the second cooling device 2 are integrated. For example, the first sheet 41 of the first cooling device 1 and the first sheet 41 of the second cooling device 2 are a single sheet. The second sheet 42 of the first cooling device 1 and the second sheet 42 of the second cooling device 2 are a single sheet. Therefore, by overlapping and joining the two sheets, the first sheet 41 and the second sheet 42, the packs 4 of the first cooling device 1 and the packs 4 of the second cooling device 2 can be easily manufactured. Furthermore, by connecting the top of the first cooling device 1 and the top of the second cooling device 2, the shoulder strap 7 can be omitted.

[0034] Other Embodiments As described above, the above embodiment has been described as an example of the technology disclosed in this application. However, the technology of the present disclosure is not limited to this and can be applied to embodiments in which modifications, substitutions, additions, omissions, etc. are made as appropriate. Furthermore, the components described in the above embodiment can be combined to create new embodiments. Furthermore, the components described in the accompanying drawings and detailed description may include 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. Therefore, the fact that these non-essential components are described in the accompanying drawings or detailed description should not be interpreted as immediately determining that these non-essential components are essential.

[0035] For example, the vertical dimension L1 of the first cooling device 1 may be more than two-thirds of the vertical dimension L2 of the second cooling device 2. The vertical dimension L1 of the first cooling device 1 may be less than one-third of the vertical dimension L2 of the second cooling device 2. The shape, size, material, etc. of the packs 4 of the first cooling device 1 and the second cooling device 2 are not limited. The material, etc. of the ice packs 3 of the first cooling device 1 and the second cooling device 2 are not limited.

[0036] The ice pack 3 of the second cooling device 2 may be arranged only below the lower end 12 of the first cooling device 1. In other words, it is sufficient that the ice pack 3 of the second cooling device 2 is arranged at least below the lower end 12 of the first cooling device 1.

[0037] The shoulder straps 7 and the waist straps 8 can be omitted.

[0038] The technology of the present disclosure can be summarized as follows.

[0039] [1] A cooling device 100, 200 to be worn on the torso 9 of a human body, comprising a first cooling device 1 forming a front body and a second cooling device 2 forming a back body, wherein the first cooling device 1 and the second cooling device 2 are each formed by an ice pack 3 and a pack 4 containing the ice pack 3, and the lower end 12 of the first cooling device 1 is positioned below the upper end 21 of the second cooling device 2 and above the lower end 22 of the second cooling device 2.

[0040] With this configuration, the torso 9 can be cooled by the first cooling device 1 and the second cooling device 2. Moreover, because the lower end 12 of the first cooling device 1 is located higher than the lower end 22 of the second cooling device 2, the abdomen 92 is less likely to be cooled by the first cooling device 1, making it less likely that the person will feel unwell. Therefore, the torso 9 can be cooled appropriately.

[0041] [2] In the cooling devices 100, 200 described in [1], the first cooling device 1 is not placed on the abdomen 92 of the human body but is placed on the chest 91 of the human body, and the second cooling device 2 is placed on the back 93 of the human body.

[0042] According to this configuration, cooling of the belly 92 by the cooling devices 100 and 200 can be further reduced.

[0043] [3] In the cooling device 100, 200 described in [1] or [2], the lower end 12 of the first cooling device 1 is located above the lower end 22 of the second cooling device 2 by at least 1 / 3 of the vertical dimension L2 of the second cooling device 2.

[0044] According to this configuration, cooling of the belly 92 by the cooling devices 100 and 200 can be further reduced.

[0045] [4] In the cooling device 100, 200 described in any one of [1] to [3], at least a part of the ice pack 3 of the second cooling device 2 is arranged below the lower end 12 of the first cooling device 1.

[0046] According to this configuration, the second cooling device 2 can cool the lower part of the back 93, and the cooling devices 100 and 200 can cool the trunk 9 even more.

[0047] [5] In the cooling device according to any one of [1] to [4], at least a part of the ice pack 3 in the second cooling device 2 is arranged above the lower end 12 of the first cooling device 1.

[0048] According to this configuration, the upper part of the back 93 can be cooled by the second cooling device 2, and the torso 9 can be further cooled by the cooling devices 100 and 200.

[0049] [6] In the cooling device 100 described in any one of [1] to [5], the pack 4 of each of the first cooling device 1 and the second cooling device 2 has a plurality of storage chambers 43 arranged at intervals and each storing the ice packs 3 individually.

[0050] With this configuration, the portions between adjacent storage chambers 43 of each pack 4 of the first cooling device 1 and the second cooling device 2 do not contain ice packs 3 and are therefore more flexible than storage chambers 43 containing ice packs 3. Therefore, each of the first cooling device 1 and the second cooling device 2 is more likely to deform to fit the shape of the body 9. Therefore, the first cooling device 1 and the second cooling device 2 can further cool the body 9. [Explanation of symbols]
