　左右の側方領域７，８の寸法は、特に限定されるものではないが、中央領域６よりも上下方向の長さが短く、首の左右の側部を前側まで十分に覆うためには、左右方向の長さとしては縦中心線ＣＬから、左右の側方領域７，８の左右方向で最も外側の外端位置ｂ（後述する摘み部７４，８４を除く）までで規定される長さＬ１が１４０ｍｍ～１６０ｍｍである。
The dimensions of the left and right lateral regions 7 and 8 are not particularly limited, but the length in the vertical direction is shorter than that of the central region 6, and in order to sufficiently cover the left and right sides of the neck to the front side, The length in the left-right direction is defined from the vertical center line CL to the outermost outer end position b (excluding the knobs 74 and 84 described later) in the left and right lateral regions 7 and 8 in the left-right direction. L1 is 140 mm to 160 mm.

　中央領域６は、その下部よりも上側の部分において、左右の側方領域７，８が連なっている。これにより、冷却具１の下側縁３は、中央領域６において部分的に下方に突き出ている、すなわち、中央領域６の下側縁６１が、左右の側方領域７，８の下側縁７１，８１における中央領域６との接続部分よりも下方に突き出ており、中央領域６の下部は周辺（左右の側方領域７，８の前記下部と隣接する部分）よりも下方に伸び出る延出部６２をなしている。なお、図１及び図４において、符号ａが指す位置は左右の側方領域７，８の下側縁７１，８１と中央領域６との接続位置、つまりは、冷却具１の下側縁３における中央領域６と左右の側方領域７，８との境界位置であり、前記接続部分は接続位置ａから所定範囲にある部分を指す。
In the central region 6, the left and right lateral regions 7 and 8 are connected in a portion above the lower portion thereof. As a result, the lower edge 3 of the cooling tool 1 partially protrudes downward in the central region 6, that is, the lower edge 61 of the central region 6 is the lower edge of the left and right lateral regions 7, 8. It protrudes below the connection portion with the central region 6 in 71 and 81, and the lower portion of the central region 6 extends downward from the periphery (the portion adjacent to the lower portion of the left and right lateral regions 7 and 8). It forms a part 62. In FIGS. 1 and 4, the position indicated by the reference numeral a is the connection position between the lower edges 71 and 81 of the left and right lateral regions 7 and 8 and the central region 6, that is, the lower edge 3 of the cooling tool 1.

　延出部６２は、首の付け根を冷却するゾーンであり、冷却具１を首に装着する際には、図５～図９に示すように、首の後部の付け根に当てられる。また、延出部６２は、冷却具１を首に装着する際に、ユーザが例えばＹシャツ等の襟付きの衣服を着用している場合にはその大部分が襟の内側に差し込まれ、ユーザが例えばＴシャツ等の襟なしの衣服を着用している場合においてもその少なくとも一部分が襟ぐり（ネックライン）の内側に差し込まれる。これにより、冷却具１の使用状態では、延出部６２がユーザの衣服により首に抑えつけられるので、首に装着した冷却具１を首から外れ難くすることができる。
The extending portion 62 is a zone for cooling the base of the neck, and when the cooling tool 1 is attached to the neck, it is applied to the base of the rear part of the neck as shown in FIGS. 5 to 9. Further, when the cooling tool 1 is attached to the neck, most of the extension portion 62 is inserted into the inside of the collar when the user is wearing clothes with a collar such as a Y-shirt, and the user. Even when wearing a collarless garment such as a T-shirt, at least a part thereof is inserted inside the neckline. As a result, in the state of use of the cooling tool 1, the extending portion 62 is held down by the user's clothes on the neck, so that the cooling tool 1 attached to the neck cannot be easily removed from the neck.

　延出部６２の下側縁６１は、特に限定されるものではないが、延出部６２をユーザの衣服の襟ぐりに良好に差し込むことができるとの観点からは、図１及び図４に示すように、前記接続位置ａからその下側の端までで規定される突出長さＬ３が４０ｍｍ～６０ｍｍである。
The lower edge 61 of the extending portion 62 is not particularly limited, but is shown in FIGS. 1 and 4 from the viewpoint that the extending portion 62 can be satisfactorily inserted into the neckline of the user's clothes. As described above, the protrusion length L3 defined from the connection position a to the lower end thereof is 40 mm to 60 mm.

　なお、本実施形態では、冷却具１は、収容体１０の内部に水を収容したものであるため、冷却具１の使用状態では、図９に示すように、収容体１０内の下部に水が溜まる結果、中央領域６の延出部６２に水が多く集まってとどまる。これにより、冷却具１は中央領域６の延出部６２における冷却効果が増大するため、首の付け根を効果的に冷却することができる。
In the present embodiment, since the cooling tool 1 contains water inside the housing body 10, in the state of use of the cooling tool 1, water is stored in the lower part of the housing body 10 as shown in FIG. As a result of the accumulation of water, a large amount of water collects and stays in the extending portion 62 of the central region 6. As a result, the cooling tool 1 increases the cooling effect at the extending portion 62 of the central region 6, so that the base of the neck can be effectively cooled.

　延出部６２の平面視形状は、図１及び図４に示す例では、矩形状であるが、三角形状、台形状（下方に向かうに連れて幅広及び幅狭のいずれの台形状を含む）、半円状、半楕円状等、その他の形状であってもよい。また、突出部６２の下側の左右の角部は、丸みを帯びているが、必ずしも丸みを帯びている必要はない。

In the present embodiment, the lower edges 71 and 81 of the left and right lateral regions 7 and 8 extend downward from the connection position a toward the outside in the left-right direction, while the outer edges 72, It is connected to 82. As a result, the tip portions 73 and 83 of the left and right lateral regions 7 and 8 protrude diagonally downward in a sharply tapered state. The tips 73 and 83 of the left and right lateral regions 7 and 8 are zones for cooling the carotid artery of the neck, and when the cooling tool 1 is attached to the neck, the left and right sides are as shown in FIGS. 5 to 9. By projecting the tips 73, 83 of the lateral regions 7 and 8 diagonally downward, the tips 73, 83 can reach the position of the carotid artery at the lower part of the left and right sides of the neck. Further, when the left and right lateral regions 7 and 8 are arranged on the left and right sides of the neck, the tip portions 73 and 83 are sharply tapered, so that the lower edges 71 and 81 (particularly the outer edges 72 and 82) are used. It is possible to prevent the part on the connection position side of the user from hitting the user's shoulder. Therefore, the cooling tool 1 can be attached to the neck with good fit, and the left and right lateral regions 7 and 8 can be in good contact with the left and right sides of the neck. The left and right sides, especially the carotid artery, can be cooled well.

　左右の側方領域７，８の斜め下側に突き出る長さは、特に限定されるものではないが、左右の側方領域７，８で頚動脈をより良好に覆うとの観点から、前記接続位置ａから最も斜め下側に突き出た先端位置ｃまでで規定される長さＬ４で１１０ｍｍ～１３０ｍｍである。
The length of the left and right lateral regions 7 and 8 protruding diagonally downward is not particularly limited, but the connection position is described from the viewpoint of better covering the carotid artery in the left and right lateral regions 7 and 8. The length L4 defined from a to the tip position c protruding most diagonally downward is 110 mm to 130 mm.

　なお、本実施形態では、冷却具１は、収容体１０の内部に水を収容したものであるため、冷却具１の使用状態では、図９に示すように、収容体１０内の下部に水が溜まる結果、左右の側方領域７，８の先端部７３，８３に水が多く集まってとどまる。これにより、冷却具１は左右の側方領域７，８の先端部７３，８３における冷却効果が増大するため、首の頚動脈を効果的に冷却することができる。
In the present embodiment, since the cooling tool 1 contains water inside the housing body 10, in the state of use of the cooling tool 1, water is stored in the lower part of the housing body 10 as shown in FIG. As a result of the accumulation of water, a large amount of water collects and stays at the tips 73 and 83 of the left and right lateral regions 7 and 8. As a result, the cooling tool 1 increases the cooling effect at the tips 73 and 83 of the left and right lateral regions 7 and 8, so that the carotid artery of the neck can be effectively cooled.

　加えて、左右の側方領域７，８の下側縁７１，８１が前記接続位置ａから左右方向の外側に向かって下側に傾斜しながら延びることにより、冷却具１の下側縁３は、中央領域６と左右の側方領域７，８との境界位置に、凹み部３０が設けられる。これにより、冷却具１を首に装着する際に、図５～図９に示すように、左右の側方領域７，８を首の左右の側部に配置したとき、冷却具１の下側縁３の凹み部３０に肩をはめ込むことができる。よって、冷却具１をユーザの肩に引っ掛けることができるので、首に装着した冷却具１を首から外れ難くすることができる。

The upper edge 2 of the cooling tool 1 is provided with a downwardly convex notch 20 having a narrow width at a position separated by a predetermined length in the left-right direction from the vertical center line CL. The notch 20 is formed by a part of the upper edge 2 of the cooling tool 1 entering downward. The notch 20 is U-shaped in the examples shown in FIGS. 1 and 4, but may have other shapes such as V-shaped, U-shaped, and semi-arc-shaped. In the upper edge 2 of the cooling tool 1, the position of the notch 20 is the boundary position between the central region 6 and the left and right lateral regions 7, 8.

　冷却具１の上側縁２の中央領域６と左右の側方領域７，８との境界位置に切込み２０が設けられていることで、左右の側方領域７，８は、中央領域６との境界位置における上下方向の長さＬ２が、中央領域６の上下方向の長さよりも短くなる。これにより、冷却具１を首に装着する際に、左右の側方領域７，８を中央領域６に対して折り曲げ易くなり、左右の側方領域７，８を首の左右の側部に容易に配置することができる。
Since the notch 20 is provided at the boundary position between the central region 6 of the upper edge 2 of the cooling tool 1 and the left and right lateral regions 7 and 8, the left and right lateral regions 7 and 8 have the same as the central region 6. The vertical length L2 at the boundary position is shorter than the vertical length of the central region 6. As a result, when the cooling tool 1 is attached to the neck, the left and right lateral regions 7 and 8 can be easily bent with respect to the central region 6, and the left and right lateral regions 7 and 8 can be easily attached to the left and right sides of the neck. Can be placed in.

　切込み２０の深さは、特に限定されるものではないが、左右の側方領域７，８を中央領域６に対して良好に折り曲げ易くするとの観点からは、中央領域６の上側縁６０の上側の端から切込み２０の底までで規定される長さＬ６で３０ｍｍ～３５ｍｍであることが好ましい。
The depth of the notch 20 is not particularly limited, but from the viewpoint of making it easy to bend the left and right lateral regions 7 and 8 with respect to the central region 6, the upper side of the upper edge 60 of the central region 6 is easily bent. The length L6 defined from the end of the notch 20 to the bottom of the notch 20 is preferably 30 mm to 35 mm.

　一対の切込み２０の間の中央領域６の上側縁６０は、図示例ではコ字状であるが、Ｕ字状、Ｖ字状、円弧状等、その他の形状であってもよい。上側縁６０の左右の角部は、図示例では丸みを帯びているが、必ずしも丸みを帯びている必要はない。また、一対の切込み２０の外側の左右の側方領域７，８の上側縁７０，８０は、図１及び図４に示す例では円弧状であるが、Ｕ字状、Ｖ字状、コ字状等、その他の形状であってもよい。

冷却具の厚み

　冷却具１の厚みは、特に限定されるものではないが、左右の側方領域７，８を中央領域６に対して良好に折り曲げ可能とし、首の左右の側部にフィット性よく沿わせて頚動脈上に密着させるとの観点からは、厚みは大きすぎないことが好ましい。一方で、冷却具１の厚みが小さすぎると、冷却具１による首への冷却効果が薄れてしまうおそれがある。よって、冷却具１の厚みは、図３に示すように冷却具１を台等の水平面に載置した状態の厚みＴで所定の大きさに設定することが好ましい。厚みＴの好適な大きさは、冷却具１の左右方向の長さ（図４に示す２つの位置ｂの間の距離２Ｌ１）に応じて定まり、冷却具１の左右方向の長さに対する比の値（Ｔ／２Ｌ１）が１／２０～１／１２であることが好ましく、１／２０～１／１５であることがさらに好ましい。なお、このときの冷却具１の上下方向の長さは、左右の側方領域７，８を中央領域６に対して良好に折り曲げ可能とする観点からは、左右方向の長さに対する比の値で１／２～２／３であることが好ましく、１／２～３／５であることがさらに好ましい。
Cooler thickness

The thickness of the cooling tool 1 is not particularly limited, but the left and right lateral regions 7 and 8 can be bent well with respect to the central region 6, and the left and right sides of the neck are fitted well. From the viewpoint of being in close contact with the carotid artery, it is preferable that the thickness is not too large. On the other hand, if the thickness of the cooling tool 1 is too small, the cooling effect of the cooling tool 1 on the neck may be diminished. Therefore, it is preferable that the thickness of the cooling tool 1 is set to a predetermined size with the thickness T of the cooling tool 1 placed on a horizontal surface such as a table as shown in FIG. The suitable size of the thickness T is determined according to the length of the cooling tool 1 in the left-right direction (distance 2L1 between the two positions b shown in FIG. 4), and is the ratio of the length of the cooling tool 1 to the length in the left-right direction. The value (T / 2L1) is preferably 1/20 to 1/12, more preferably 1/20 to 1/15. The length of the cooling tool 1 in the vertical direction at this time is a value of a ratio to the length in the left-right direction from the viewpoint of enabling the left and right lateral regions 7 and 8 to be satisfactorily bent with respect to the central region 6. It is preferably 1/2 to 2/3, and more preferably 1/2 to 3/5.

　例えば、冷却具１の左右方向の長さ２Ｌ１が２８０ｍｍ～３２０ｍｍである場合には、冷却具１による冷却効果も加味して、冷却具１の厚みＴは２０ｍｍ～２５ｍｍであることが好ましい。
For example, when the length 2L1 of the cooling tool 1 in the left-right direction is 280 mm to 320 mm, the thickness T of the cooling tool 1 is preferably 20 mm to 25 mm in consideration of the cooling effect of the cooling tool 1.

冷却具の作用・効果

　上述した本実施形態の冷却具１によると、図１及び図４に示すように、左右の側方領域７，８の下側縁７１，８１は、中央領域６との接続位置ａから左右方向の外側に向かって下側に傾斜して延びながら、外側縁７２，８２と接続されている。そのため、左右の側方領域７，８の先端部７３，８３は斜め下側に大きく突き出るので、冷却具１を首に装着する際に、図５～図９に示すように、左右の側方領域７，８の先端部７３，８３を首の左右の側部の下部にある頚動脈の位置まで届かせることができる。さらに、左右の側方領域７，８の先端部７３，８３がシャープに先細るので、その下端縁７１，８１（特に外側縁７２，８２との接続位置側の部分）がユーザの肩に当たらないように左右の側方領域７，８を首の左右の側部に配置することができる。よって、冷却具１をフィット性よく首に装着でき、左右の側方領域７，８で首の左右の側部、特に頚動脈を十分に覆うことができるので、頚動脈を良好に冷却することができる。
Action / effect of cooling device

According to the cooling tool 1 of the present embodiment described above, as shown in FIGS. 1 and 4, the lower edges 71 and 81 of the left and right lateral regions 7 and 8 are in the left-right direction from the connection position a with the central region 6. It is connected to the outer edges 72 and 82 while sloping downward toward the outside of the. Therefore, since the tip portions 73 and 83 of the left and right lateral regions 7 and 8 protrude diagonally downward, when the cooling tool 1 is attached to the neck, the left and right lateral regions are shown as shown in FIGS. 5 to 9. The tips 73, 83 of regions 7, 8 can be reached to the location of the carotid artery at the bottom of the left and right sides of the neck. Further, since the tip portions 73 and 83 of the left and right lateral regions 7 and 8 are sharply tapered, if the lower end edges 71 and 81 (particularly the portion on the connection position side with the outer edges 72 and 82) hit the user's shoulder. The left and right lateral regions 7 and 8 can be arranged on the left and right sides of the neck so as not to be present. Therefore, the cooling tool 1 can be attached to the neck with good fit, and the left and right lateral regions 7 and 8 of the neck can sufficiently cover the left and right sides of the neck, particularly the carotid artery, so that the carotid artery can be cooled well. ..

　なお、図２及び図３に示すように、冷却具１が内部に水１３及び水１３に溶解するときに吸熱反応を示す冷却剤１１を収容した収容体１０からなることにより、冷却具１の使用状態では、収容体１０内の下部に水１３が溜まる。そのため、冷却具１の使用状態では、図９に示すように、首の頚動脈を冷却する左右の側方領域７，８の先端部７３，８３に水１３が多く集まってとどまることから、冷却具１は当該先端部７３，８３による冷却効果が増大する。よって、首の頚動脈を効果的に冷却することができる。
