Problems solved by technology

[0003] However, this conventional heating element is used by sticking to the skin through the adhesive layer formed on the back surface. Therefore, there is a problem that the heating element formed with the adhesive layer does not follow the deformation in accordance with the movement of the body, and there is discomfort during use. sense problem
In addition, when used for a long time, there is a problem of low-temperature burns caused by the continuous adhesion of the adhesive layer of the heat-generating component to the skin of the body, and when low-temperature burns are caused, the heat-generating body may be peeled off together with the adhesive layer. The bad phenomenon that peeled off the skin

Embodiment 1）

[0152] Made of nylon non-woven fabric with a length of 70mm and a width of 75mm (weight per unit area 40g / m 2 ) on a base material composed of a polyethylene layer with a length of 70mm, a width of 75mm, and a thickness of 40μm. 40g / m 2 ) is laminated with a polyethylene porous film with a length of 100 mm, a width of 115 mm, and a thickness of 70 μm. The base material and the coating material are sealed around the periphery of the heat-generating composition to form a heat-generating component. An adhesive composed of an acrylic solvent-based adhesive was applied (coating thickness: 23 μm) to prepare the heating element of Example 1.

Embodiment 2）

[0154] The heat generating element of Example 2 provided a protective sheet with a length of 80 mm, a width of 85 mm, and a thickness of 0.38 mm on the heat generating member of the heat generating element of Example 1.

[0155] For the protective sheet, a polyethylene film with a thickness of 28 μm is laminated on a metallocene polyethylene film with a thickness of 12 μm, and a coating amount of 6±1 g / m is applied on it. 2 Coated with acrylic adhesive, using lamination with a weight per unit area of ​​55±5g / m 2 100% rayon fiber non-woven fabric structure, the non-woven fabric is placed on the sensor side of the tester and placed on the heat generating part.

[0156] In addition, temperature measurement was carried out under the following measurement conditions.

[0170] Next, in order to further verify the effectiveness of the protective sheet, an example in which the basis weight and raw materials of the nonwoven fabric were changed will be described.

[0171] It is made of man-made fiber spunlace non-woven fabric with a length of 70mm and a width of 75mm (the weight per unit area is 45g / m 2 ) is laminated with a polyethylene resin film with a thickness of 40 μm to place the exothermic composition on the substrate, and the exothermic composition is covered with a spunlace nonwoven fabric made of PET with a length of 70 mm and a width of 75 mm (weight per unit area: 30 g / m 2 ) on a covering material formed by laminating a polyethylene resin porous film with a thickness of 70 μm, and sealing the substrate and the covering material around the exothermic composition to form a heat generating member. Moreover, the mesh sheet (weight per unit area: 40 g / m 2 ), apply an adhesive made of acrylic solvent-based adhesive (coating thickness: 23 ...

Abstract

The purpose of the present invention is to provide a heat generator, which causes no discomfort in using, in which a heat-generating member is not directly adhered to the user's skin by using an adhesive, which reduces the burden on the skin even in the case of sensitive skin or continuous use, and which is free from a risk of low temperature burn. The heat generator is characterized in that: a heat-generating member having a wide surface is formed on a mesh-type sheet, said mesh-type sheet being larger than the external shape of one wide surface of the heat-generating member; and an adhesive layer is formed on a part of the mesh-type sheet, said part being positioned at the outer periphery of the heat-generating member.

Description

technical field [0001] The present invention relates to a heating element comprising a heating element configured to generate heat from a heating composition such as iron powder, which is directly attached to the skin of the body for use. Background technique [0002] Conventionally, as such a heating element, as shown in Patent Document 1, there is known a heating element in which an adhesive layer is formed on the back surface of the heating element attached to the body, and the adhesive layer is attached to the skin for use. . [0003] However, this conventional heating element is used by sticking to the skin through the adhesive layer formed on the back surface. Therefore, there is a problem that the heating element formed with the adhesive layer does not follow the deformation in accordance with the movement of the body, and there is discomfort during use. problem of feeling. In addition, when used for a long time, there is a problem of low-temperature burns caused by...
