Description
本発明は、発熱具に関する。より具体的には、本発明は、優れた温感と冷感が呈され、温熱作用を効果的に発揮できる発熱具に関する。
The present invention relates to a heating tool. More specifically, the present invention relates to a heating tool that exhibits an excellent warm feeling and cool feeling and can effectively exert a warming action.
空気と接触して発熱する発熱性組成物を利用した発熱具は、防寒等のための保温具としてのみならず、血行促進や疼痛緩和等のための治療用具等としても広く使用されている。
Heating devices using a heat-generating composition that generates heat upon contact with air are widely used not only as a heat retention device for cold protection, but also as a treatment device for blood circulation promotion and pain relief.
従来の発熱具では、治療用具として使用する場合、夏場等の暑い時期には、温感のみでは暑熱感として感じられ、使用感が悪くなるという欠点がある。従来、発熱具の温感は、発熱性組成物の組成、発熱性組成物を収容する収容体による酸素流入量等を調節することによってコントロールできることが知られているが、このような発熱具の温感のコントロールでは、最高到達温度、昇温速度、持続時間等を調節できるに止まり、夏場等の暑い時期に知覚される暑熱感を減じることはできない。
In the case of using a conventional heating device as a treatment device, there is a drawback that in a hot season such as summer, a warm feeling alone is felt as a hot feeling, and the feeling of use becomes worse. Conventionally, it has been known that the thermal sensation of a heating tool can be controlled by adjusting the composition of the exothermic composition, the amount of oxygen inflow by the container containing the exothermic composition, and the like. In the control of warmth, it is possible to adjust the maximum temperature reached, the rate of temperature rise, the duration, etc., and it is not possible to reduce the hotness perceived in hot seasons such as summer.
そこで、近年、冷感を呈させることにより、暑熱感が減じられる発熱具が開発されている。例えば、特許文献1には、発熱性組成物に清涼感を付与する冷感剤を配合した発熱具は、清涼感を知覚できることが報告されている。また、特許文献2には、発熱性組成物に、冷感剤とセスキテルペン炭化水素を特定量配合した発熱具は、温熱感と清涼感を知覚できることが報告されている。更に、特許文献3には、発熱性組成物に、環状エーテル構造を有するモノテルペノイドと環状ケトン構造を有するモノテルペノイドを特定量配合した発熱具は、保存中の清涼感の質の変化を効果的に防止し、清涼感が維持できることが報告されている。しかしながら、特許文献1~3のように、発熱性組成物に冷感剤等を配合する技術では、呈される温感が減じてしまい、優れた温感と冷感を両立させることができないという欠点がある。また、発熱具において、発熱性組成物は、通気性を有する収容体に収容されているため、特許文献1~3のように、発熱性組成物に冷感剤等を配合した発熱具では、冷感剤等の一部が収容体の通気孔を介して大気中に揮散するため、冷感の持続性が低いという欠点もある。
Therefore, in recent years, heating tools have been developed that reduce the feeling of heat by presenting a cool feeling. For example, Patent Document 1 reports that a heating tool containing a cooling sensation agent that imparts a refreshing feeling to an exothermic composition can perceive a refreshing feeling. Patent Document 2 reports that a heating tool in which a specific amount of a cooling sensate and a sesquiterpene hydrocarbon is blended in an exothermic composition can perceive warmth and coolness. Furthermore, Patent Document 3 discloses that a heating tool in which a specific amount of a monoterpenoid having a cyclic ether structure and a monoterpenoid having a cyclic ketone structure is blended in an exothermic composition is effective in changing the quality of cool feeling during storage. It is reported that it can prevent and maintain a refreshing feeling. However, as in Patent Documents 1 to 3, the technique of blending a cooling sensation agent or the like with the exothermic composition reduces the exhibited warm feeling and cannot achieve both excellent warm feeling and cool feeling. There are drawbacks. In the heating tool, since the exothermic composition is contained in a breathable container, as in Patent Documents 1 to 3, in the heating tool in which a cooling sensation agent or the like is blended with the exothermic composition, Since a part of the cooling sensation agent or the like is volatilized into the atmosphere through the ventilation holes of the container, there is also a disadvantage that the cooling sensation is low.
近年、発熱具の機能性の向上に対する消費者の要望が高まっており、温感と冷感が共に高く知覚され、効果的に温熱作用を発揮できる発熱具の開発が切望されている。
In recent years, there has been an increasing demand for consumers to improve the functionality of heating tools, and there is an urgent need for the development of heating tools that can perceive both warmth and coldness and that can effectively exert warmth.
本発明の目的は、優れた温感と冷感が呈され、温熱作用を効果的に発揮できる発熱具を提供することである。
An object of the present invention is to provide a heating tool that exhibits an excellent warm feeling and cool feeling and can effectively exert a warming action.

(Criteria for warm and cold feeling)
4: Feels very strong 3: Feels strong 2: Feels weak 1: Feels very weak 0: Does not feel at all
得られた結果を図7及び8に示す。温感に関しては、粘着層に生姜エキスを単独で含む場合(比較例3)では、粘着層に有効成分を含まない場合(比較例1)と同程度の温感が呈されていたが、粘着層にメントール又はカンフルを単独で含む場合(比較例2及び3)では、粘着層に有効成分を含まない場合(比較例1)に比して、呈される温感が低下していた。これに対して、粘着層にメントールと生姜エキス及び/又はカンフルを含む場合(実施例1~3)では、粘着層に生姜エキスを単独で含む場合(比較例3)に比して、温感が向上しており、メントールと生姜エキス及び/又はカンフルとの相乗作用による温感向上が認められた。とりわけ、メントール、生姜エキス、及びカンフルを含む場合(実施例1)には、温感の向上が格別顕著に認められた。
The results obtained are shown in FIGS. Regarding the warm feeling, when the ginger extract was included alone in the adhesive layer (Comparative Example 3), the same warm feeling as when the active ingredient was not included in the adhesive layer (Comparative Example 1) was exhibited. In the case where menthol or camphor was included alone in the layer (Comparative Examples 2 and 3), the warm feeling exhibited was lower than in the case where the adhesive layer did not contain an active ingredient (Comparative Example 1). On the other hand, when the adhesive layer contains menthol and ginger extract and / or camphor (Examples 1 to 3), the warmth is higher than when the adhesive layer contains ginger extract alone (Comparative Example 3). The improvement of warmth was recognized by the synergistic action of menthol and ginger extract and / or camphor. In particular, when menthol, ginger extract, and camphor were included (Example 1), the improvement in warmth was recognized remarkably.
また、冷感に関しては、粘着層にメントールを単独で含む場合(比較例2)では、粘着層に有効成分を含まない場合(比較例1)に比して、冷感が向上していたが、粘着層に生姜エキス又はカンフルを単独で含む場合(比較例3及び4)では、粘着層に有効成分を含まない場合(比較例1)と同程度の冷感が知覚された。これに対して、粘着層にメントールと生姜エキス及び/又はカンフルを含む場合(実施例1~3)では、粘着層にメントールを単独で含む場合(比較例2)に比して、冷感が向上しており、しかも冷感の持続性も格段に向上していた。特に、粘着層に、メントール、生姜エキス、及びカンフルを含む場合(実施例1)では、冷感の向上が格別顕著に認められた。
In addition, with respect to the cooling sensation, in the case where menthol was included alone in the adhesive layer (Comparative Example 2), the cooling sensation was improved compared to the case where the adhesive layer did not contain an active ingredient (Comparative Example 1). When the ginger extract or camphor was included alone in the adhesive layer (Comparative Examples 3 and 4), the same cooling sensation was perceived as when the active layer was not included in the adhesive layer (Comparative Example 1). In contrast, when the adhesive layer contains menthol and ginger extract and / or camphor (Examples 1 to 3), the cooling sensation is less than when the adhesive layer contains menthol alone (Comparative Example 2). In addition, the sustainability of the cold feeling was also greatly improved. In particular, when the adhesive layer contains menthol, ginger extract, and camphor (Example 1), an improvement in cooling sensation was recognized remarkably.
即ち、以上の結果から、粘着層にメントールと生姜エキス及び/又はカンフルを含む場合、特にメントール、生姜エキス、及びカンフルを含む場合において、相乗的に温感と冷感が向上することが明らかとなった。
That is, from the above results, it is clear that when the menthol and ginger extract and / or camphor are included in the adhesive layer, especially when menthol, ginger extract and camphor are included, the warm and cool feelings are synergistically improved. became.
試験例2:皮膚温度の評価
2名の被験者によって、実施例1及び比較例1の発熱具によってもたらされる皮膚温度について評価した。具体的には、被験者の左肩に実施例1の発熱具を貼付し、右肩に比較例1の発熱具を貼付した。貼付前及び貼付開始から60分後に、赤外線サーモグラフィーを用いて、皮膚表面温度の測定を行った。なお、貼付開始から60分後の皮膚温度については、発熱具を貼った状態と発熱具を剥がした状態の双方について測定した。 Test Example 2: Evaluation of skin temperature The skin temperature produced by the heating tools of Example 1 and Comparative Example 1 was evaluated by two subjects. Specifically, the heating tool of Example 1 was stuck on the left shoulder of the subject, and the heating tool of Comparative Example 1 was stuck on the right shoulder. The skin surface temperature was measured using infrared thermography before application and after 60 minutes from the start of application. In addition, about the skin temperature 60 minutes after the sticking start, it measured about both the state which stuck the heating tool, and the state which peeled the heating tool.

得られた結果を図9に示す。図9から明なように、実施例1の発熱具は、皮膚温度は比較例1の場合と同程度であった。即ち、本試験結果から、実施例1の発熱具は、比較例1の発熱具と同程度の皮膚温度をもたらすにも拘わらず、知覚される温感及び冷感の向上が図られていることが明らかとなった。
The obtained results are shown in FIG. As is clear from FIG. 9, the heating tool of Example 1 had the same skin temperature as that of Comparative Example 1. That is, from this test result, although the heating tool of Example 1 brings about the same skin temperature as the heating tool of Comparative Example 1, the perceived warmth and coolness are improved. Became clear.
試験例3:腰痛緩和効果の評価
腰痛を感じている10名の被験者によって、実施例1及び比較例1の発熱具の腰痛緩和効果を評価した。具体的には、被験者の腰部に、実施例1及び比較例1の発熱具を60分間貼付し、腰痛の程度をVAS(Visual Analogue Scale)にて経時的に評価した。VAS評価では、「痛みが無い」を0点(最少点数)、「これ以上の痛みがないくらい痛い」を150点(最大点数)として、感じられる腰痛の程度を評点化した。10名の被験者によって評点化された腰痛の程度の平均値を算出することにより、腰痛緩和効果を評価した。 Test Example 3: Evaluation of low back pain relief effect The low back pain relief effect of the fever of Example 1 and Comparative Example 1 was evaluated by 10 subjects who felt low back pain. Specifically, the heating tools of Example 1 and Comparative Example 1 were applied to the lower back of the subject for 60 minutes, and the degree of lower back pain was evaluated over time using a VAS (Visual Analogue Scale). In the VAS evaluation, “no pain” was scored as 0 (minimum score), and “no pain more than that” was scored as 150 (maximum score), and the degree of low back pain felt was scored. The back pain alleviation effect was evaluated by calculating the average value of the back pain graded by 10 subjects.
