Specifically, this disclosure relates to the following aspects.

[Mode 1]

1. A warm-feeling sheet comprising a liquid-holding or liquid-permeable skin-contact sheet, a liquid-impermeable wear-resistant sheet, and a fixing member for fixing the skin-

Wherein the warm sheet comprises a warm agent for activating a TRP channel and a warm agent composition comprising a solvent and does not contain a heat generating agent.

Since the warm sheet does not contain a heat generating agent and includes a predetermined warming composition including a warming agent, warmth can be given to the wearer without directly heating the skin of the wearer from the outside. Therefore, when the warm-feeling sheet is fixed to the wearer's wearer, a low-temperature image is hardly generated in a portion of the skin of the wearer that touches the warm-feeling sheet in contact with the warm-feeling sheet, and sufficient warmth can be given to the wearer. In addition, since the warm sheet can impart warmth to the wearer without directly heating the skin of the wearer from the outside, the warm sheet is hardly softened after the warm sheet is fixed to the wearer's wear, It is difficult for the fixing portion to remain in the garment.

[Mode 2]

The warm sheet of embodiment 1, wherein the warm agent is an agonist for TRPV1 receptor.

In the warm sheet, since the warm agent is an agonist for the TRPV1 receptor, the wearer can feel a temperature exceeding 43 DEG C, which is referred to as the activation temperature threshold of the TRPV1 receptor, when using the warm sheet, . Further, as a result of activating the TRPV1 receptor at the contact portion of the warm sensation agent that has come into contact with the warm sensation agent of the wearer's skin by the warm agent, heat is generated from the warm sensation agent contact portion through the sympathetic nervous system, The temperature of the contact portion can be raised.

[Mode 3]

Wherein the skin contact sheet comprises the warm composition.

In the warm sheet, the skin contact sheet contacting the skin of the wearer contains a predetermined warm composition, so that the wearer tends to feel warm from the initial stage after wearing the warm sheet.

[Mode 4]

The warm sheet according to any one of claims 1 to 3, wherein the warm composition comprises the solvent in a proportion of 50.0 to 99.9 mass%.

[Mode 5]

The warm feeling sheet according to any one of claims 1 to 4, wherein the air permeability of the skin contact sheet is higher than the air permeability of the wear contact sheet.

Since the air permeability of the skin-contact sheet is higher than the air-permeability of the wear-resistant sheet, the solvent contained in the warm-feeling composition moves through the skin-contact sheet to the outside, So that it is difficult for the fixing portion to remain in the garment when the warm sheet is discarded. When moisture, such as heat and sweat, is generated from the contact portion of the warm feeling agent which has come into contact with the warm feeling agent of the wearer's skin by the warm feeling agent, the moisture such as heat and sweat passes through the wear- It is difficult for the fixing portion to be influenced by the moisture such as heat and sweat, so that the fixing portion is less likely to remain in the garment when the warm sheet is discarded.

[Mode 6]

The soft feeling sheet according to any one of claims 1 to 5, wherein a thermal conductivity of the skin-contact sheet is lower than a thermal conductivity of the wear-resistant sheet.

In the warm sheet, since the thermal conductivity of the skin-contact sheet is lower than the thermal conductivity of the wear-resistant sheet, when heat is generated from the hot-skin contact portion of the wearer's skin, the heat passes through the skin- It becomes difficult to reach the inside of the warm-feeling sheet, that is, the fixed portion of the warm-feeling sheet. As a result, the fixing portion is hardly affected by the heat, and the fixing portion hardly remains in the garment when disposing the warm sheet.

[Mode 7]

The warm sheet as set forth in any one of claims 1 to 6, further comprising an intermediate layer between the skin-contact sheet and the contact-facing sheet.

Since the warm sheet further includes an intermediate layer between the skin-contact sheet and the wear-and-tear sheet, moisture such as heat and sweat generated from the warm-skin contact portion of the skin of the wearer passes through the skin- Therefore, it is difficult for the fixing portion to be affected by the moisture due to the heat, sweat, or the like, and the fixing portion remains in the garment when disposing the warm sheet. It gets harder.

[Mode 8]

And the air permeability of the intermediate layer is higher than the air permeability of the abutting sheet.

In the warm sheet, since the air permeability of the intermediate layer is higher than the air permeability of the wear-resistant sheet, the solvent contained in the warm composition passes through the skin-contact sheet and moves to the outside, , It is difficult for the fixing portion to remain in the garment when disposing the warm sheet. In addition, in the case of generating heat such as heat and sweat from the contact portion of the warm feeling agent which has come into contact with the warm feeling agent of the wearer's skin by the warm feeling agent, the moisture such as heat and sweat passes through the wear- It is difficult for the fixing portion to be influenced by the moisture such as heat and sweat, and the fixing portion is hardly retained in the garment when the warm sheet is discarded.

[Mode 9]

Wherein the thermal conductivity of the intermediate layer is lower than the thermal conductivity of the abutting sheet.

Since the thermal conductivity of the intermediate layer is lower than the thermal conductivity of the wear-resistant sheet, the heat generated from the warm-feeling contact portion of the skin of the wearer passes through the skin-contact sheet and the intermediate layer to reach the fixed portion of the warm- It is difficult for the fixing portion to be influenced by the solvent, moisture, etc., so that the fixing portion hardly remains in the garment when the warm sheet is discarded.

[Mode 10]

The warm sheet according to any one of claims 1 to 9, wherein the warming composition and the fixing portion are disposed at positions overlapping in the thickness direction of the warming sheet.

In the warm sheet, since the warm composition is placed at a position overlapping the thickness of the warm sheet in the thickness direction of the warm sheet, it is easy to keep the warm composition in contact with the skin of the wearer. It is difficult to do.

[Mode 11]

The warm sheet as set forth in any one of claims 1 to 10, wherein the solvent is selected from the group consisting of water, an alcohol and a fat, and any combination thereof.

In the warm sheet, since the solvent is selected from a predetermined group, the warm agent can quickly impart warmth to the wearer's skin.

Hereinafter, the warmth sheet of the present disclosure will be described in detail.

The skin-contact sheet 7 includes a warm-feeling composition (not shown) on the entire surface of the skin-contact sheet 7. The skin contact sheet 7 has a skin contact surface 31 and a skin non-contact surface 33.

In the warm sheet 1, the skin-contact sheet 7, the intermediate layer 9, the liquid-impermeable contact sheet 11, and the release sheet 15 each have a flat surface L) and the widthwise direction (W) are the same, and the skin contact sheet 7, the intermediate layer 9, the liquid impermeable wearer contact sheet 11, the release sheet 15 are stacked so that their outer edges are overlapped in the thickness direction (T).

The warm sheet 1 has a folding axis F extending in parallel with the width direction W at the center of the longitudinal direction L. [ In the individual package 3, the warm sheet 1 is opened with the skin abutment surface 31 of the skin abutment sheet 7 as the inner side with reference to the folding axis F, And is packed in the sheet 5.

The fixing portion 13 is constituted by a plurality of fixing portions 14. Each of the plurality of fixed portion portions 14 extends in the width direction W and reaches both end portions in the width direction W of the warm sheet 1. [ The plurality of fixed portion portions 14 are arranged at a predetermined interval in the longitudinal direction L.

The release sheet 15 has the same shape as that of the abutment sheet 11 and the outer edge and is arranged so as to cover the entirety of the fixing portion 13 (the plurality of fixing portions 14).

As shown in Fig. 1, the warm sheet 1 is packed in a package sheet 5 in a folded state in two, and an individual package 3 is formed. Specifically, the individual package 3 has the warm-feeling sheet 1 folded in two with the skin-contact face 31 of the skin-contact sheet 7 as the inner side with respect to the folding axis F, Is formed by interposing two sheets of the packaging sheet 5 and providing a seal portion 101 at the peripheral edge portion of the two sheets of the packaging sheet 5.

The wearer can open the individual package 3 from the notch 103 of the individual package 3 of the warm sheet and remove the warm sheet 1 from the individual package 3 to remove the warm sheet 1 The release sheet 15 is peeled off. 6, the wearer fixes the fixing portion 13 of the warm sheet 1 on the inner surface of the garment 21, specifically the inner surface of the shorts, The warm sheet 1 is used in a state in which the wearer's skin 31 is in contact with the wearer's skin.

As shown in Figs. 3 and 4, the warm sheet 1 has a peripheral edge portion 25, which is an area within a predetermined distance from the outer peripheral edge 23 of the warm sheet 1.
