Embodiments for Carrying Out the Invention

[0009] Hereinafter, exemplary embodiments will be described in detail with reference to the drawings. Figure 1 is a front view of the vest 100 with the front body closed.

[0010] The vest 100 is worn on the torso of the human body 9 to cool the human body 9. The vest 100 is an example of clothing. Clothing is a covering that covers at least a part of the human body 9. Clothing includes, in addition to clothes such as vests, for example, bedding, footwear, gloves, and the like. Hereinafter, the vest 100 will be described using the direction of the human body 9 on which the vest 100 is worn. That is, the front of the human body 9 on which the vest 100 is worn is defined as "front". The same applies to "rear", "left", "right", "upper", and "lower".

[0011] Figure 2 is a front view of the vest 100 with the front body part opened. The vest 100 includes a clothing body 2, a cooling device 3 disposed inside the clothing body 2, and a hook-and-loop fastener 4 disposed between the clothing body 2 and the cooling device 3. The hook-and-loop fastener 4 detachably connects the clothing body 2 and the cooling device 3. That is, in the vest 100, the cooling device 3 is detachably attached inside the clothing body 2 by the hook-and-loop fastener 4. When the vest 100 is worn on the human body 9, the cooling device 3 directly contacts the human body 9 or an undergarment worn on the human body 9. Thereby, the human body 9 is efficiently cooled.

[0012] Figure 3 is a front view of the clothing body 2 with the front body part 21 opened. In Figure 3, a state in which the cooling device 3 is removed from the vest 100 is depicted. The clothing body 2 is formed from cotton, hemp, chemical fiber, or other fabrics. The clothing body 2 includes a front body part 21, a back body part 22, and a string fastener 23 attached to the front body part 21. The front body part 21 includes a right front body part 21r disposed on the right side and a left front body part 21l disposed on the left side. The string fastener 23 detachably connects the right front body part 21r and the left front body part 21l. Thereby, the front body part 21 can be opened and closed by the string fastener 23.

[0013] Figure 4 is a schematic diagram of the cooling device 3. The cooling device 3 cools the human body 9. In this example, the cooling device 3 includes a first cooling device 31, a second cooling device 32, and a third cooling device 33. That is, the cooling device 3 is divided into three parts. As shown in Figure 2, the first cooling device 31 is detachably attached inside the right front body part 21r. The second cooling device 32 is detachably attached inside the left front body part 21l. The third cooling device 33 is detachably attached inside the back body part 22. Hereinafter, when the first cooling device 31, the second cooling device 32, and the third cooling device 33 are not distinguished, they are simply referred to as "cooling device 3".

[0014] The cooling device 3 is plate-shaped. In this example, the cooling device 3 is rectangular. The cooling device 3 has flexibility and can be bent or folded. As shown in FIG. 4, the cooling device 3 has a longitudinal direction, a short-side direction, and a thickness direction orthogonal to both the longitudinal direction and the short-side direction. In this example, the longitudinal direction is substantially orthogonal to the short-side direction.

[0015] FIG. 5 is a cross-sectional view of the vest 100 along the line V-V in FIG. 2. The cooling device 3 is exposed inside the clothing body 2. In other words, in a state where the vest 100 is worn on the human body 9 (see FIG. 1), the cooling device 3 is exposed toward the side from the clothing body 2 to the human body 9. The cooling device 3 has a cold storage agent 5 and an exterior pack 6 that houses the cold storage agent 5. In FIG. 5, for convenience of explanation, dots are added to the cold storage agent 5.

[0016] The cold storage agent 5 is a PCM (Phase Change Material) that absorbs heat and changes from a solid phase to a liquid phase. The cold storage agent 5 contains, for example, aliphatic hydrocarbons. The aliphatic hydrocarbons are, for example, paraffin or aliphatic saturated hydrocarbons. The cold storage agent 5 may contain at least one of tetradecane (C 14 H 30 ), hexadecane (C 16 H 34 ), and octadecane (C 18 H 38 ). The cold storage agent 5 may contain only one or only two of tetradecane, hexadecane, and octadecane, or may contain all of them. In addition to aliphatic hydrocarbons, the cold storage agent 5 may further contain a super absorbent polymer (SAP), water, aroma, graphite, an organic substance, or a mineral, etc. The melting point of the cold storage agent 5 is, for example, normal temperature. The melting point of the cold storage agent 5 is preferably 5°C or higher and 35°C or lower, and more preferably 15°C or higher and 35°C or lower. The cold storage agent 5 absorbs the heat of the human body as sensible heat in the solid phase and liquid phase. When the cold storage agent 5 changes from the solid phase to the liquid phase, it absorbs the heat of the human body as latent heat, specifically, heat of fusion.

[0017] The exterior pack 6 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). In this example, the exterior pack 6 is made of thermoplastic polyurethane.

[0018] More specifically, the outer pack 6 includes a plurality of storage sections 61 that individually store ice packs 5, and partition sections 62 that divide the internal space into the plurality of storage sections 61. Each of the plurality of storage sections 61 is sealed. That is, the ice packs 5 are individually stored in each storage section 61.

[0019] The outer pack 6 is formed by overlapping and joining two sheets. Specifically, the outer pack 6 is formed by joining a first sheet 71 and a second sheet 72 that face each other in the thickness direction. The sheet that faces the clothing body 2 is the first sheet 71, and the sheet that faces the human body 9 when the vest 100 is worn on the human body 9 is the second sheet 72.

[0020] In this example, the first sheet 71 is flat. Meanwhile, the second sheet 72 has multiple recesses 72a recessed away from the first sheet 71. Each recess 72a is blocked by the first sheet 71. The first sheet 71 and the second sheet 72 are joined together so that each recess 72a is sealed by the first sheet 71. Specifically, the portion of the second sheet 72 excluding the recesses 72a, i.e., the outer periphery of the second sheet 72 and the portion between adjacent recesses 72a, are joined to the first sheet 71. The joining of the first sheet 71 and the second sheet 72 is achieved, for example, by thermal welding. Note that in FIG. 5, the boundaries of the joined portions in the outer pack 6 are indicated by solid lines, but in reality, the boundaries of the joined portions do not need to be clearly visible. The storage section 61 is formed by the recesses 72a and the first sheet 71. The partition 62 is formed by joining the first sheet 71 and a portion of the second sheet 72 between adjacent recesses 72a.

[0021] 6 is a partially enlarged view of FIG. 4. In this example, each of the multiple storage sections 61 has a generally rectangular shape with rounded corners. The multiple storage sections 61 are arranged in both the short and long directions so that the short sides are generally parallel to the short direction and the long sides are generally parallel to the long direction. When the vest 100 is in use, the multiple storage sections 61 come into direct contact with the human body 9 or underwear worn by the human body 9, thereby cooling the human body 9.

[0022] In this example, the exterior pack 6 further has a plurality of ventilation holes 63 penetrating the thickness direction of the exterior pack 6. The plurality of ventilation holes 63 are formed in the partition section 62. Each ventilation hole 63 is disposed between two adjacent storage sections 61 in the longitudinal direction with respect to the longitudinal position, and is also disposed between two adjacent storage sections 61 in the lateral direction with respect to the lateral position.

[0023] As shown in FIG. 5, the surface fastener 4 includes a first surface fastener 41 attached to the inside of the clothing body 2 and a second surface fastener 42 attached to the outer pack 6. The first surface fastener 41 engages with the second surface fastener 42. The first surface fastener 41 is a surface fastener of either the male type or the female type, and the second surface fastener 42 is a surface fastener of the other type of either the male type or the female type. The surface fastener 4 is formed of, for example, nylon.

[0024] As shown in FIG. 3, in this example, a plurality of first surface fasteners 41 are attached to the clothing body 2. Each first surface fastener 41 is, for example, sewn to the clothing body 2. Each first surface fastener 41 is disposed at a predetermined position on each of the right front part 21r, the left front part 21l, and the back part 22. Specifically, each first surface fastener 41 is disposed at a position corresponding to the second surface fastener 42.

[0025] As shown in FIG. 6, in this example, a plurality of second surface fasteners 42 are attached to the outer pack 6. Specifically, the second surface fastener 42 is attached to the first sheet 71 (see FIG. 5) of the outer pack 6. The second surface fastener 42 does not overlap the partition portion 62 in a plan view, that is, when viewed from the thickness direction of the cooling device 3. In other words, in this example, the second surface fastener 42 is disposed inside the outer peripheral edge of the housing portion 61 in a plan view.

[0026] Specifically, as shown in FIG. 5, an attachment sheet 8 is disposed between the outer pack 6 and the second surface fastener 42. The second surface fastener 42 is attached to the outer pack 6 via the attachment sheet 8. Specifically, the attachment sheet 8 is attached to the first sheet 71 by, for example, heat welding. The second surface fastener 42 is attached to the attachment sheet 8 by, for example, heat welding, sewing, or the like.

[0027] As shown in FIG. 6, in this example, the mounting sheet 8 has a substantially rectangular shape with rounded corners. The mounting sheet 8 is housed within the housing portion 61 in a plan view. In other words, the mounting sheet 8 is disposed inside the outer peripheral edge of the housing portion 61 in a plan view. The second surface fastener 42 is housed within the mounting sheet 8 in a plan view. In other words, the second surface fastener 42 is disposed inside the outer peripheral edge of the mounting sheet 8 in a plan view. In this example, the planar area of the second surface fastener 42 is smaller than the planar area of the mounting sheet 8. That is, at least a part of the peripheral portion of the mounting sheet 8 does not overlap with the second surface fastener 42.

[0028] As shown in FIG. 4, in this example, the second surface fastener 42 is disposed in a part of the plurality of housing portions 61. Specifically, the second surface fastener 42 is disposed in every other housing portion 61 arranged in the longitudinal direction.

[0029] In this example, the elastic modulus of the mounting sheet 8 is greater than the elastic modulus of the exterior pack 6. That is, the mounting sheet 8 has lower stretchability than the exterior pack 6. The elastic modulus of the second surface fastener 42 is greater than the elastic modulus of the exterior pack 6. That is, the second surface fastener 42 has lower stretchability than the exterior pack 6. The elastic modulus may be evaluated, for example, by the tensile elongation measured in a tensile test. The tensile elongation is measured, for example, in accordance with ASTM D638. The mounting sheet 8 is formed of, for example, polyvinyl chloride (PVC).

[0030] Next, an example of a method for manufacturing the cooling device 3 to which the second surface fastener 42 is attached will be described. First, a flat first sheet 71, a second sheet 72 having a recess 72a, and an attachment sheet 8 are prepared. Subsequently, the second surface fastener 42 is attached to the attachment sheet 8 by, for example, heat welding, sewing, or the like. Subsequently, the attachment sheet 8 to which the second surface fastener 42 is attached is attached to a predetermined position of the first sheet by, for example, heat welding. Subsequently, the second sheet 72 is overlaid on the surface of the first sheet 71 where the attachment sheet 8 is not attached, and the outer peripheral edge of the first sheet 71 and the outer peripheral edge of the second sheet 72 are joined by, for example, heat welding. At this time, joining is performed over the entire length of the outer peripheral edge except for a part of the outer peripheral edge of the first sheet 71. The part of the outer peripheral edge that is not joined serves as an injection port for injecting the cold insulating agent 5. By joining the first sheet 71 and the second sheet 72, a bag-shaped sheet having an injection port, that is, an outer packaging pack 6 in the shape of a bag including the first sheet 71 and the second sheet 72 is formed. Subsequently, the liquid-phase cold insulating agent 5 is injected into the outer packaging pack 6 from the injection port. The injected cold insulating agent 5 flows into each recess 72a. Subsequently, a non-joined portion of the overlapping portion of the first sheet 71 and the second sheet 72, that is, a portion of the outer packaging pack 6 between the injection port and two adjacent recesses 72a is joined by, for example, heat welding. By joining the portions between two adjacent recesses 72a, a partition portion 62 is formed. Subsequently, ventilation holes 63 are formed in the partition portion 62. Thus, the cooling device 3 to which the second surface fastener 42 is attached is manufactured.

[0031] Next, an example of a method for using the vest 100 will be described. The cooling device 3 is removed from the clothing body 2 before use and, for example, left at room temperature. As a result, the cold insulating agent 5 becomes solid. Note that the cooling device 3 may be cooled by a refrigerator or the like before use.

[0032] The user engages the first surface fastener 41 and the second surface fastener 42 to attach the first cooler 31 inside the right front torso area 21r. Similarly, the second cooler 32 is attached inside the left front torso area 21l, and the third cooler 33 is attached inside the back torso area 22. By wearing the vest 100 with the coolers 3 attached, the heat of the torso is absorbed by the coolant 5 through the outer pack 6, and the torso is cooled. The coolant 5 melts and changes to a liquid phase by absorbing the heat of the torso. In this case, the coolant 5 absorbs the heat of the torso using not only sensible heat but also latent heat, so the torso is efficiently cooled. When the coolant 5 becomes liquid due to use, the user can place the cooler 3 in a normal temperature environment to change the coolant 5 back to a solid phase and return it to a coolable state.

[0033] In such a vest 100, the cooler 3 is detachably attached inside the clothing body 2, and the cooler 3 is exposed inside the clothing body 2. As a result, when the vest 100 is worn on the human body 9, the cooler 3 can be brought into direct contact with the human body 9 or undergarments worn on the human body 9. Consequently, in the vest 100 with the detachable cooler 3, the cooling performance can be improved. If the clothing body has a storage bag and the vest is configured such that the cooler can be inserted into and removed from the storage bag, there is a risk that the storage bag or the like may impede the cooling performance of the cooler.

[0034] Also, the second surface fastener 42 is attached to the outer pack 6 via the attachment sheet 8. Thereby, for example, even when the attachment strength is low when the second surface fastener 42 is directly attached to the outer pack 6, by interposing the attachment sheet 8 with a high attachment strength to both the outer pack 6 and the second surface fastener 42 between the outer pack 6 and the second surface fastener 42, the second surface fastener 42 can be firmly attached to the outer pack 6.

[0035] In particular, in this example, the second surface fastener 42 is contained within the mounting sheet 8 in plan view. This allows, for example, the peripheral edge of the mounting sheet 8 to be exposed from the second surface fastener 42. As a result, this peripheral edge can be used as the portion of the mounting sheet 8 that is attached to the outer pack 6, making it easy to perform, for example, heat welding.

[0036] Furthermore, the elastic modulus of the attachment sheet 8 is greater than that of the outer pack 6. This limits the amount of expansion and contraction of the outer pack 6 even when the outer pack 6 expands and contracts. As a result, the possibility that the second surface fastener 42 will peel off from the outer pack 6 can be reduced.

[0037] Furthermore, because the second surface fasteners 42 do not overlap the partition portions 62 in plan view, it is possible to easily form the partition portions 62. More specifically, as described above, the partition portions 62 are formed by, for example, heat welding the first sheet 71 and the second sheet 72 together, so by ensuring that the second surface fasteners 42 do not overlap the partition portions 62 in plan view, it is possible to easily press the partition portions 62 when heat welding them. If the second surface fasteners 42 overlap the partition portions 62 in plan view, the presence of the second surface fasteners 42 could make pressing difficult.

[0038] Furthermore, the second surface fastener 42 is attached to the first sheet 71 of the outer pack 6. In this example, the first sheet 71 is flat, which makes it easier to attach the second surface fastener 42 to the first sheet 71 than when the first sheet 71 has an uneven surface, for example.

[0039] 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.

[0040] For example, the clothing of the present disclosure is not limited to a vest, but may be clothing other than a vest, as well as headgear, footwear, gloves, etc.

[0041] The shape of the cooling tool 3 is not limited. For example, the shape of the cooling tool 3 may be a polygon other than a rectangle, or may have a curved outer shape. In the above embodiment, the cooling tool 3 is divided into three parts, but the number of divisions is not limited, and it may not even be divided. The shape, arrangement, number, etc. of the storage sections 61 are also not limited.

[0042] The shape of the outer pack 6 is not limited. For example, the first sheet 71 does not have to be flat. The first sheet 71 may have a plurality of recesses formed therein that are recessed in the opposite direction from the second sheet 72. In this case, the partition 62 may be formed by joining a portion between adjacent recesses 72a of the second sheet 72 and a portion between adjacent recesses of the first sheet 71.

[0043] The plurality of first surface fasteners 41 is not limited to the above-described configuration. For example, in the plurality of first surface fasteners 41 attached to the back body 22, the plurality of first surface fasteners arranged in the left-right direction may be connected to each other and integrated. That is, in the back body 22, one first surface fastener extending in the left-right direction may be arranged with three in the up-down direction. The same applies to the right front body 21r and the left front body 21l.

[0044] The second surface fastener 42 may be directly attached to the exterior pack 6 without passing through the attachment sheet 8. The second surface fastener 42 does not have to be accommodated within the attachment sheet 8 in plan view. The second surface fastener 42 may overlap the partition portion 62 in plan view.

[0045] The shape, arrangement, number, etc. of the attachment sheet 8 are not limited. For example, the attachment sheet 8 may be arranged straddling the accommodation portion 61 and the partition portion 62. The elastic modulus of the attachment sheet 8 may be approximately the same as the elastic modulus of the exterior pack, or may be smaller than the elastic modulus of the exterior pack.

[0046] [Aspect] The above-described embodiment is a specific example of the following aspects.

[0047] (Aspect 1) The vest 100 (clothing) is a vest 100 that covers at least a part of the human body 9, and includes a clothing body 2, a plate-shaped cooling device 3 disposed inside the clothing body 2 for cooling the human body 9, and a surface fastener 4 disposed between the clothing body 2 and the cooling device 3 for detachably connecting the clothing body 2 and the cooling device 3, and the cooling device 3 is exposed inside the clothing body 2.

[0048] According to this configuration, the cooler 3 is detachably attached to the inside of the clothing body 2, and the cooler 3 is exposed inside the clothing body 2. As a result, when the vest 100 is worn on the human body 9, the cooler 3 can be brought into direct contact with the human body 9 or underwear or the like worn on the human body 9. As a result, in the vest 100 in which the cooler 3 is detachable, the cooling performance can be improved. If the clothing body has a storage bag and the vest allows the cooler to be inserted into and removed from the storage bag, there is a risk that the storage bag or the like may inhibit the cooling performance of the cooler.

[0049] (Aspect 2) In the vest 100 according to Aspect 1, the cooler 3 includes a cold storage agent 5 and an outer packaging pack 6 that houses the cold storage agent 5, and the hook-and-loop fastener 4 includes a first hook-and-loop fastener 41 attached to the inside of the clothing body 2 and a second hook-and-loop fastener 42 attached to the outer packaging pack 6 and engaging with the first hook-and-loop fastener 41.

[0050] According to this configuration, a configuration can be realized in which the cooler 3 is detachably attached to the inside of the clothing body 2 and the cooler 3 is exposed inside the clothing body 2.

[0051] (Aspect 3) The vest 100 according to Aspect 1 or 2 further includes a mounting sheet 8 disposed between the outer packaging pack 6 and the second hook-and-loop fastener 42, and the second hook-and-loop fastener 42 is attached to the outer packaging pack 6 via the mounting sheet 8.

[0052] According to this configuration, for example, even when the mounting strength is low when the second hook-and-loop fastener 42 is directly attached to the outer packaging pack 6, by interposing a mounting sheet 8 having a high mounting strength with both the outer packaging pack 6 and the second hook-and-loop fastener 42 between the outer packaging pack 6 and the second hook-and-loop fastener 42, the second hook-and-loop fastener 42 can be firmly attached to the outer packaging pack 6.

[0053] (Aspect 4) In the vest 100 according to any one of Aspects 1 to 3, the second hook-and-loop fastener 42 is housed within the mounting sheet 8 in a plan view.

[0054] With this configuration, for example, the peripheral edge of the mounting sheet 8 can be exposed from the second surface fastener 42. As a result, this peripheral edge can be used as the portion of the mounting sheet 8 that is attached to the outer pack 6, facilitating, for example, heat welding.

[0055] (Aspect 5) In the vest 100 according to any one of the first to fourth aspects, the elastic modulus of the attachment sheet 8 is greater than the elastic modulus of the outer pack 6 .

[0056] According to this configuration, even if the outer pack 6 expands or contracts, the amount of expansion or contraction of the outer pack 6 is suppressed. As a result, the possibility that the second surface fastener 42 will be peeled off from the outer pack 6 can be reduced.

[0057] (Aspect 6) In the vest 100 described in any one of aspects 1 to 5, the outer pack 6 includes a plurality of storage sections 61 that individually store the ice packs 5, and a partition section 62 that divides the internal space into the plurality of storage sections 61, and the second hook-and-loop fastener 42 does not overlap the partition section 62 in a planar view.

[0058] This configuration makes it easier to form the divider 62. More specifically, since the divider 62 is formed by, for example, heat welding a part of the outer package 6, by ensuring that the second surface fastener 42 does not overlap the divider 62 in a plan view, the divider 62 can be easily pressed when heat welding is performed. If the second surface fastener 42 overlaps the divider 62 in a plan view, the presence of the second surface fastener 42 may make pressing difficult.

[0059] (Aspect 7) In the vest 100 described in any one of aspects 1 to 6, the outer pack 6 has a flat first sheet 71 and a second sheet 72 opposite the first sheet 71, and the second hook-and-loop fastener 42 is attached to the first sheet 71.

[0060] According to this configuration, because first sheet 71 is flat, second surface fastener 42 can be attached to first sheet 71 more easily than when first sheet 71 has irregularities, for example. [Explanation of symbols]
