(a)は従来の中材の冷却後の状態、(b)は本発明における中材の冷却後の状態を表す。(A) shows the state after cooling of the conventional intermediate material, and (b) shows the state after cooling of the intermediate material in the present invention.

以下、本発明における冷感マットの実施の形態を、図面に基づいて説明する。
図1に、本発明の冷感マット1の一好適例の全体斜視図を、図2に、その拡大断面図を、それぞれ示す。図示する冷感マット1は、上面材2と、下面材3と、これら上面材2と下面材3との間に挟持された中材4と、を備えるものであり、中材4は水、硫酸ナトリウム、塩化ナトリウムおよび炭素粉末10からなる。
Hereinafter, embodiments of a cooling mat according to the present invention will be described with reference to the drawings.
FIG. 1 is an overall perspective view of a preferred example of the cooling sensation mat 1 of the present invention, and FIG. The illustrated cooling sensation mat 1 includes an upper surface material 2, a lower surface material 3, and an intermediate material 4 sandwiched between the upper surface material 2 and the lower surface material 3. The intermediate material 4 is water, It consists of sodium sulfate, sodium chloride and carbon powder 10.

かかる構成としたことで、本発明の冷感マット1は、冷蔵庫で冷却したり氷を使用したりしなくても、簡便に、且つ効果的に体熱を吸収することができる。また、炭素粉末10を配合したことにより、中材4の結晶粒の固形化を良好に解消することが可能となり、頭部や頸部等に対する違和感を生ずることがない。   With this configuration, the cooling sensation mat 1 of the present invention can absorb body heat simply and effectively without cooling in a refrigerator or using ice. Further, by blending the carbon powder 10, it is possible to satisfactorily eliminate the solidification of the crystal grains of the intermediate material 4, and there is no sense of incongruity with the head, neck, or the like.

本発明の所望の効果を得る上で、水100質量部に対し、硫酸ナトリウムは30〜90質量部、塩化ナトリウムは10〜40質量部とすることが好ましい。また、炭素粉末は中材全体に対し0.5〜5質量%であることが好ましく、特に好ましくは1質量%程度である。   In obtaining the desired effect of the present invention, it is preferable that sodium sulfate is 30 to 90 parts by mass and sodium chloride is 10 to 40 parts by mass with respect to 100 parts by mass of water. Moreover, it is preferable that carbon powder is 0.5-5 mass% with respect to the whole inside material, Most preferably, it is about 1 mass%.

図示する例では、上面材2および下面材3はいずれも二層構造からなる。上面材2は、外側に配設されるポリエステルからなる外層シート5と、内側に配設される塩化ビニルからなる内層シート6とからなり、また、下面材3は、外側に配設されるポリエステルからなる外層シート7と、内側に配設される塩化ビニルからなる内層シート8からなる。これら上面材2を構成する外層シート5および内層シート6と、下面材3を構成する外層シート7および内層シート8とは、それぞれホットメルト溶着剤を介して接着されている。また、上面材2と下面材3との周縁は熱溶着加工にて接合されている。   In the illustrated example, both the upper surface material 2 and the lower surface material 3 have a two-layer structure. The upper surface material 2 is composed of an outer layer sheet 5 made of polyester disposed on the outer side and an inner layer sheet 6 made of vinyl chloride disposed on the inner side, and the lower surface material 3 is made of polyester disposed on the outer side. And an inner layer sheet 8 made of vinyl chloride disposed inside. The outer layer sheet 5 and the inner layer sheet 6 constituting the upper surface material 2 and the outer layer sheet 7 and the inner layer sheet 8 constituting the lower surface material 3 are bonded to each other via a hot melt welding agent. Moreover, the periphery of the upper surface material 2 and the lower surface material 3 is joined by the heat welding process.

上面材2と下面材3との間には、前述したように、水、硫酸ナトリウム、塩化ナトリウムおよび炭素粉末10からなる混合物の中材4が封入されている。   Between the upper surface material 2 and the lower surface material 3, as described above, the middle material 4 of a mixture composed of water, sodium sulfate, sodium chloride, and carbon powder 10 is enclosed.

硫酸ナトリウムは、通常、乾燥剤として用いられており、人体に対して安全性の高い物質として知られている。また硫酸ナトリウムの水溶液は、加熱すると約32℃までは溶解度が温度に比例して上がり続けるが、この温度に達すると水和物としての結晶(NaSO・10HO)ではなく、NaSOの結晶へと変化する。また、硫酸ナトリウムは、
融解の際、周囲の熱を吸熱し温度を下げることで、寒剤として高い効果が得られる。
Sodium sulfate is usually used as a desiccant and is known as a highly safe substance for the human body. When heated, the aqueous solution of sodium sulfate continues to increase in proportion to the temperature up to about 32 ° C., but when this temperature is reached, it is not a hydrate crystal (Na 2 SO 4 .10H 2 O) but Na. It changes into 2 SO 4 crystals. Sodium sulfate
When melting, it absorbs the surrounding heat and lowers the temperature, so that a high effect as a cryogen can be obtained.

本発明によれば、中材4の一部として硫酸ナトリウムを封入し、かかる中材4を使用した冷感マット1を身体下部に敷設することで、体温により硫酸ナトリウム水溶液の溶解度が上昇する。そのことにより、冷感マット1が身体から発生される熱を効率よく吸水するので、使用者は心地よい冷感を得ることができる。   According to the present invention, sodium sulfate is encapsulated as a part of the intermediate material 4, and the cooling sensation mat 1 using the intermediate material 4 is laid at the lower part of the body, whereby the solubility of the aqueous sodium sulfate solution is increased by the body temperature. As a result, the cooling sensation mat 1 efficiently absorbs water generated from the body, so that the user can obtain a comfortable cooling sensation.

また、硫酸ナトリウムとともに中材4を構成する塩化ナトリウムは、工業的に大量に消費されているものを好適に使用することができる。   Moreover, the sodium chloride which comprises the intermediate material 4 with sodium sulfate can use what is consumed industrially in large quantities suitably.

中材4の一部として塩化ナトリウムを混合することで、結晶状態の中材4が大粒化することなく、使用の直後における中材4の違和感を解消することが可能となる。   By mixing sodium chloride as a part of the intermediate material 4, it is possible to eliminate the uncomfortable feeling of the intermediate material 4 immediately after use without increasing the size of the intermediate material 4 in a crystalline state.

さらに、かかる中材4に、炭素粉末10を配合することにより、中材4が周囲の体熱を吸熱する際、硫酸ナトリウムと塩化ナトリウムの粒子間に炭素粉末10が配置され、結晶粒の固形化を防ぐことができる。炭素粉末10は、黒炭、備長炭等の木炭や、竹炭、活性炭、ヤシガラ炭等、有機物を炭素化させたものを粉末状にして形成されたものであればよく、特に制限されるものではない。また、既に炭素化された黒鉛を粉末にしてもよい。   Further, by blending the carbon powder 10 with the intermediate material 4, when the intermediate material 4 absorbs the surrounding body heat, the carbon powder 10 is disposed between the sodium sulfate and sodium chloride particles, and the solids of the crystal grains Can be prevented. The carbon powder 10 is not particularly limited as long as it is formed by carbonizing an organic substance such as charcoal such as black charcoal and bincho charcoal, bamboo charcoal, activated carbon, coconut husk charcoal, or the like. . Alternatively, graphite that has already been carbonized may be powdered.

本発明の冷感マット1においては、炭素粉末10を、水、硫酸ナトリウム、塩化ナトリウムの混合物中に均一に分散させて混合する。なお、炭素粉末10の粉末の粒度は特に限定されるものではないが、2〜200μmのものが好ましい。   In the cooling sensation mat 1 of the present invention, the carbon powder 10 is uniformly dispersed and mixed in a mixture of water, sodium sulfate, and sodium chloride. The particle size of the carbon powder 10 is not particularly limited, but is preferably 2 to 200 μm.

図2に示すように、本発明の冷感マットにおいては、上面材2と下面材3とが、高周波加工にて好適に熱溶着されている。高周波加工は、熱融着性素材に高周波エネルギーを加えることにより、被溶着物の一部を溶解し結合させる溶着加工である。高周波加工を用いることで、上面材2と下面材3とを熱溶着した箇所には、熱溶着部9が形成される。   As shown in FIG. 2, in the cooling sensation mat of the present invention, the upper surface material 2 and the lower surface material 3 are suitably heat-welded by high frequency processing. The high frequency processing is a welding processing in which a part of the object to be welded is dissolved and bonded by applying high frequency energy to the heat-fusible material. By using high-frequency processing, a heat-welded portion 9 is formed at a location where the upper surface material 2 and the lower surface material 3 are heat-welded.

熱溶着部9は、上面材2と下面材3の周囲、および、マット長手方向の複数箇所にて形成することが好ましい。図示するように、熱溶着部9を、マット長手方向の複数箇所にて、平行状態で形成することで、使用中において中材4の偏りが生じることがなくなる。また、熱溶着部9の形成により、冷感マット1を三つ折りに折り畳むことや、六つ折りに折り畳むことも可能となるので、携帯や収納が容易になるというメリットも得られる。   It is preferable to form the heat welding part 9 around the upper surface material 2 and the lower surface material 3 and at a plurality of locations in the mat longitudinal direction. As shown in the drawing, by forming the heat welding portions 9 in a parallel state at a plurality of locations in the mat longitudinal direction, the middle material 4 is not biased during use. Moreover, since the cooling sensation mat 1 can be folded in three folds or folded in six folds by forming the heat-welded portion 9, there is an advantage that it is easy to carry and store.

また、上面材2および/または下面材3には、防水加工を施す。上面材2および/または下面材3に防水加工を施すことにより、身体からの発汗による汗が中材4まで浸透すると共に、内材4が滲み出ることがなくなり、湿気によるカビや雑菌の発生を防止する効果が得られる。防水加工は、表面を防水性を有する材料により被覆するか、または疎水化して、水の浸透を防ぐ加工であり、油脂やワックス、液状の合成樹脂、シリコーン等素材が使用される。防水加工は、上面材2の外層シート5の表面と、下面材3の外層シート7の表面とに、それぞれ施す。   Further, the upper surface material 2 and / or the lower surface material 3 is waterproofed. By applying a waterproof process to the upper surface material 2 and / or the lower surface material 3, sweat from the body permeates into the middle material 4, and the inner material 4 does not ooze out, thereby generating mold and germs due to moisture. The effect of preventing is obtained. The waterproofing process is a process of preventing the penetration of water by covering the surface with a waterproof material or making it hydrophobic, and materials such as fats and oils, wax, liquid synthetic resin, and silicone are used. The waterproofing is applied to the surface of the outer layer sheet 5 of the upper surface material 2 and the surface of the outer layer sheet 7 of the lower surface material 3.

さらに、上面材2および/または下面材3には、防カビ加工を施すことが好ましい。上面材2および/または下面材3に防カビ加工を施すことにとで、冷感マット1の表面にカビや雑菌が発生することを防止できる。防カビ加工は、銀、銅、亜鉛、ゼオライト、キトサン等の天然系抗菌剤や、酸化チタン等の無機系の素材を、塗布するかシート内に練り込むことにより防カビ加工を施すことができる。   Further, it is preferable that the upper surface material 2 and / or the lower surface material 3 is subjected to anti-mold processing. By applying anti-mold processing to the upper surface material 2 and / or the lower surface material 3, it is possible to prevent mold and germs from being generated on the surface of the cooling sensation mat 1. Anti-mold processing can be applied by applying or kneading natural antibacterial agents such as silver, copper, zinc, zeolite, chitosan and inorganic materials such as titanium oxide into the sheet. .

本発明の冷感マット1は、夏季の寝苦しい夜などに快適な睡眠を得るために、頭部や頸部の下に敷設させる枕としての使用はもとより、ベッドパッドや敷布団パッド、クッションパッド等に幅広く利用することができる。また、その他にも、ノート型パソコンの下に敷設させることで、パソコンから放出される熱気を吸収して、好適な条件での使用が実現できる。   The cold sensation mat 1 of the present invention is used not only as a pillow laid under the head or neck, but also as a bed pad, a mattress pad, a cushion pad, etc., in order to obtain a comfortable sleep at night when it is difficult to sleep in summer. Can be used widely. In addition, by laying under a notebook computer, the hot air released from the computer can be absorbed and used under suitable conditions.

なお、本発明の冷感マット1の大きさについては、特に限定されるものではなく、枕に使用する小型のタイプから、ベッドパットに使用する大型サイズのものまで、用途に応じて、適宜寸法とすることができる。その一例として、30cm×15cmの小型パットから、90cm×140cmの大型パットとしての冷感パットを形成することができる。   In addition, about the magnitude | size of the cooling sensation mat 1 of this invention, it does not specifically limit, It is a dimension suitably according to a use from the small type used for a pillow to the large size used for a bed pad. It can be. As an example, a cold sensation pad as a large pad of 90 cm × 140 cm can be formed from a small pad of 30 cm × 15 cm.

以下、本発明を実施例に基づき説明する。

図示するように、炭素粉末10を配合していない中材4内には、固形化された結晶粒11が検出されたのに対し、炭素粉末10を配合させた中材4においては、結晶粒は確認されなかった。   As shown in the figure, solidified crystal grains 11 were detected in the intermediate material 4 not containing the carbon powder 10, whereas in the intermediate material 4 containing the carbon powder 10, crystal grains were detected. Was not confirmed.

なお、溶解温度と凝固温度の差を大きく、さらに凝固時間を長く設定すると、炭素粉末10を配合していない中材4内は、固形化された結晶粒11の量が増え、バリバリとした肌触りとなったが、炭素粉末10を配合した本発明に係るの中材4には、それ程の変化は見られなかった。   If the difference between the melting temperature and the solidification temperature is set large and the solidification time is set longer, the amount of the solidified crystal grains 11 increases in the intermediate material 4 not containing the carbon powder 10, and the skin feels crisp. However, the intermediate material 4 according to the present invention in which the carbon powder 10 was blended did not change so much.
