A sheet 11, a fixing part 13 for fixing the warming sheet 1 to the clothes, and a release sheet 15 for temporarily fixing the fixing part 13 in that order, the longitudinal direction L, the width direction W, and the thickness direction T. The skin contact sheet 7 is coated with a warming sensation composition (not shown) on the entire surface, and the entire surface of the skin contact sheet 7 constitutes the warming layer 17. Further, in the temperature sensitive sheet 1, the whole of the planar direction (longitudinal direction L and width direction W) forms a temperature sensitive layer 17 and a temperature sensitive layer overlapping region (not shown) overlapping in the thickness direction T. Yes. Further, the skin contact sheet 7 has a skin contact surface 31 and a skin non-contact surface 33.
　温感シート１では、肌当接シート７と、中間層９と、液不透過性の着衣当接シート１１と、剥離シート１５とのそれぞれは、平面方向（長手方向Ｌ及び幅方向Ｗ）の外縁の形状が同一であり、肌当接シート７と、中間層９と、液不透過性の着衣当接シート１１と、剥離シート１５とが、それらの外縁が厚さ方向Ｔに一致するように積み重ねられている。 In the warm sensation sheet 1, the skin contact sheet 7, the intermediate layer 9, the liquid-impermeable clothing contact sheet 11, and the release sheet 15 are each in the planar direction (longitudinal direction L and width direction W). The shape of the outer edge is the same, and the skin contact sheet 7, the intermediate layer 9, the liquid-impermeable clothing contact sheet 11, and the release sheet 15 are such that their outer edges match the thickness direction T. Are stacked.
　温感シート１は、長手方向Ｌの中心に、幅方向Ｗと平行に延びる折軸Ｆを備える。なお、個包装体３では、温感シート１は、折軸Ｆを基準として、肌当接シート７の肌当接面３１を内側にして折り畳まれ、包装シート５に包装されている。 The warm sheet 1 includes a folding axis F extending in parallel with the width direction W at the center in the longitudinal direction L. In the individual package 3, the warm sensation sheet 1 is folded with the skin contact surface 31 of the skin contact sheet 7 on the inside with the folding axis F as a reference, and is packaged in the packaging sheet 5.
　固定部１３は、複数の固定部部分１４から構成されている。複数の固定部部分１４のそれぞれは、幅方向Ｗに延びており、温感シート１の幅方向Ｗの両端部まで達している。複数の固定部部分１４は、長手方向Ｌに所定の間隔をあけて配置されている。
　剥離シート１５は、着衣当接シート１１と外縁の形状が同一であり、固定部１３（複数の固定部部分１４）の全体を覆うように配置されている。 The fixed portion 13 is composed of a plurality of fixed portion portions 14. Each of the plurality of fixed portion portions 14 extends in the width direction W and reaches both ends of the temperature-sensitive sheet 1 in the width direction W. The plurality of fixed portion portions 14 are arranged at predetermined intervals in the longitudinal direction L.
The release sheet 15 has the same outer edge shape as the clothing contact sheet 11 and is disposed so as to cover the entire fixing portion 13 (the plurality of fixing portion portions 14).
　図１に示されるように、温感シート１は、２つ折りされた状態で、包装シート５に包装され、個包装体３が形成されている。具体的には、個包装体３は、折軸Ｆを基準として、肌当接シート７の肌当接面３１を内側にして２つ折りされた温感シート１を、２枚の包装シート５で挟み、２枚の包装シート５の周縁部にシール部１０１を設けることにより形成されている。 As shown in FIG. 1, the warm sensation sheet 1 is wrapped in a wrapping sheet 5 in a folded state, and an individual wrapping body 3 is formed. Specifically, the individual wrapping body 3 is composed of two wrapping sheets 5 each of which is a warm sensation sheet 1 that is folded in two with the skin contact surface 31 of the skin contact sheet 7 as an inner side with respect to the folding axis F. It is formed by providing a seal portion 101 at the peripheral edge of the two packaging sheets 5.
　着用者は、個包装体３の切欠部１０３から、個包装体３を開封し、個包装体３から温感シート１を取り出し、温感シート１から剥離シート１５を剥離する。次いで、図６に示されるように、着用者は、温感シート１の固定部１３を、着衣２１、具体的にはショーツの内面に固定し、温感シート１の肌当接面３１が着用者の肌に接した状態で、温感シート１を使用する。 The wearer unpacks the individual package 3 from the notch 103 of the individual package 3, takes out the warm sheet 1 from the individual package 3, and peels the release sheet 15 from the warm sheet 1. Next, as shown in FIG. 6, the wearer fixes the fixing portion 13 of the thermal sensation sheet 1 to the clothing 21, specifically the inner surface of the shorts, and the skin contact surface 31 of the thermal sensation sheet 1 wears. The thermal sensation sheet 1 is used in a state in contact with the person's skin.
　温感シート１は、図３及び図４に示されるように、温感シート１の外周縁２３から所定の距離範囲内にある領域である周縁部２５を有する。温感シート１は、周縁部２５に、エンボス部を有しない。そうすることにより、着用者が、温感シート１の着用の際、並びに温感シート１の使用中において、温感シート１の周縁部２５に硬さを感じにくく、温感シート１が、初期及び使用時の両方において、着用感に優れる。 As shown in FIGS. 3 and 4, the warm sensation sheet 1 has a peripheral edge 25 that is a region within a predetermined distance from the outer peripheral edge 23 of the warm sensation sheet 1. The warm sensation sheet 1 does not have an embossed portion at the peripheral edge portion 25. By doing so, when the wearer wears the warming sensation sheet 1 and during use of the warming sensation sheet 1, the wearer hardly feels the hardness of the peripheral edge 25 of the warming sensation sheet 1. In both use and use, it is excellent in wearing feeling.
　温感シート１の肌当接シート７の、周縁部２５を含む全面には、温感組成物（図示せず）が塗工されている。換言すると、温感シート１は、周縁部２５に、温感組成物（図示せず）を含む肌当接シート７、すなわち、温感層１７を含む。そうすることにより、温感組成物が、着用者の肌の温感剤が接触している温感剤接触部分のＴＲＰチャネルを効率よく活性化し、着用者に温感を効率よく付与することができる。 A warming sensation composition (not shown) is coated on the entire surface including the peripheral edge 25 of the skin contact sheet 7 of the warming sensation sheet 1. In other words, the warm sensation sheet 1 includes the skin contact sheet 7 containing the warm sensation composition (not shown), that is, the warm sensation layer 17 at the peripheral edge 25. By doing so, the warming composition can efficiently activate the TRP channel of the warming agent contact portion where the warming agent on the skin of the wearer is in contact, and can efficiently impart warmth to the wearer. it can.
　温感シート１は、発熱剤を含まない。発熱剤を含む温熱シートでは、発熱剤を着用者の肌に接触させ続けることを目的とし、固定部が、発熱剤と、温熱シートの厚さ方向に重複する位置に配置されるのが一般的であり、発熱剤の影響を受け、固定部の温度が上昇し、固定部が軟化しやすい。従って、温熱シートの使用を終え、温熱シートを着衣から取り外す際に、軟化した固定部が、着衣に残りやすくなる。
　一方、温感シート１では、温感シート１自体が発熱しないので、温感シート１の固定部１３が軟化しにくく、温感シート１の使用を終え、温感シート１を着衣２１から取り外す際に、温感シート１の固定部１３が、着衣２１に残りにくい。 The warm sheet 1 does not contain a heat generating agent. In the thermal sheet containing a heat generating agent, the fixing part is generally arranged at a position overlapping the heat generating agent and the thickness direction of the heat sheet for the purpose of keeping the heat generating agent in contact with the skin of the wearer. Under the influence of the heat generating agent, the temperature of the fixing part rises and the fixing part is easily softened. Therefore, when the use of the thermal sheet is finished and the thermal sheet is removed from the clothing, the softened fixing portion tends to remain on the clothing.
On the other hand, in the warm sensation sheet 1, since the warm sensation sheet 1 itself does not generate heat, the fixing part 13 of the warm sensation sheet 1 is hard to be softened, and when the warm sensation sheet 1 is used and removed from the clothing 21. In addition, the fixing portion 13 of the warm sensation sheet 1 is unlikely to remain on the clothing 21.
　本開示の温感シートは、温感層と、温感シートの厚さ方向に重複する温感層重複領域において、好ましくは４．０以下、より好ましくは３．０以下、さらに好ましくは、２．０以下、そしてさらにいっそう好ましくは１．５以下の剛軟度変化率を有する。そうすることにより、温感シートが、初期及び使用時の両方において、着用感に優れる。なお、上記剛軟度変化率の下限は、特に存在しないが、例えば、０．５、１．０が挙げられる。 The warming sensation sheet of the present disclosure is preferably 4.0 or less, more preferably 3.0 or less, and even more preferably 2 in the warming layer and the warming layer overlapping region overlapping in the thickness direction of the warming sheet. 0.0 or less, and even more preferably 1.5 or less. By doing so, a warm feeling sheet is excellent in a feeling of wearing both in the initial stage and at the time of use. In addition, although the minimum of the said bending resistance change rate does not exist in particular, 0.5 and 1.0 are mentioned, for example.
　上記温感シートは、所定の方向において、上述の剛軟度変化率を有することが好ましく、温感シートの長手方向及び幅方向の少なくとも一方において、上述の剛軟度変化率を有することがより好ましく、そして温感シートの長手方向及び幅方向の両方において、上述の剛軟度変化率を有することがさらに好ましい。温感シートの初期及び使用時の着用感の観点からである。 The temperature-sensitive sheet preferably has the above-described bending resistance change rate in a predetermined direction, and more preferably has the above-described bending resistance change rate in at least one of the longitudinal direction and the width direction of the heating sheet. It is more preferable to have the above-described bending change rate in both the longitudinal direction and the width direction of the warm sheet. It is from a viewpoint of the feeling of wear at the initial stage and use of a warm feeling sheet.
