And a heating element 13 is sealed in a space between the pair of sheets 11 and 12 formed inside the joint 2. The heating element 13 is a heating element that generates heat when it comes into contact with air, and is made of a heating element composition containing iron powder as a main component, like a normal disposable body warmer. The material for forming the pair of sheets 11 and 12 forming the enclosing portion of the heating element 13 is preferably a non-woven fabric from the viewpoints of air permeability, productivity, feel at the time of skin contact, and the like, but is not limited thereto. Alternatively, a material such as a synthetic resin porous film can be used. In addition, different materials and different characteristics may be used for the sheet on the front side and the sheet on the back side of the heating device 1.

The connecting portions C1 to C3 between the heat generating portions A and B in each pair are foldable by a foldable sheet so that the adhesive surface a and the peeling surface b can be brought into contact with each other and adhered. Is formed. The sheet forming the connecting portion is not particularly limited as long as it can be bent, and a flexible sheet such as a synthetic resin such as polyethylene, a woven fabric made of natural fibers such as cotton, and various nonwoven fabrics can be used. In the present embodiment, the sheet 3 is laminated and adhered to the back side of the heating tool 1 so as to be bridged between the pair of heat generating parts A and B, and the connecting part C1 that can be bent by the sheet 3 is used.

Among them, a rubber-based or acrylic-based pressure-sensitive adhesive that is hardly affected by a temperature change during use. Is preferred. The application mode of the adhesive material is not particularly limited as long as the adhesive surface a can be formed, and may be an intermittent application mode such as a dot shape or a line shape in addition to the solid coating.

Each of the peeling surfaces b of the heat generating portions B1 to B3 is formed by a peeling process. More specifically, the sheet 3 is a sheet that has been subjected to release processing, and each release surface b is formed of the sheet 3 that has been subjected to release processing. In the heating device 1 of the present embodiment, as shown in FIG. 1, all the peeled surfaces b are formed by one sheet subjected to a peeling treatment. The release surface b in the present invention is obtained by applying a release treatment agent to the surface of the sheet forming the enclosing portion of the heating element, releasing tape, release paper, release-treated nonwoven fabric, release-treated polyethylene laminated paper, and release treatment. It may be formed by attaching a release member such as a polyethylene film. still,
As the release treatment agent or the release agent component of the release member, a silicone resin type, a fluorine resin type, an octadecyl isocyanate type or the like is preferable.

In this embodiment, each pair of heat generating portions P1
1 to 3 are arranged in a V-shape, as shown in FIG. 1, and the heating tool 1 is arranged in each pair of heat generating portions P1 to P3 as indicated by arrows in FIG. 1. Each adhesive surface a
And the peeling surface b can be brought into contact with each other and bonded together.

In this case, the sheets can be further laminated by bending.

Next, a method of using the heating device 1 of the present embodiment will be described. In FIG. 3, in order to relieve menstrual pain by heating the lower abdomen, at least one of the heating portion A having the adhesive surface a and the heating device 1 at the upper edge portion of the shorts 4 An example is shown in which the heat generating member A and the other heat generating portion B forming a pair are adhered to the other surface of the shorts 4 (the surface of the shorts front portion). . In addition, this heating tool may be used by adhering the heat generating portion A2 to the back surface of the front portion of the shorts, and making the heat generating portion B2 forming a pair with the heat generating member A2 face the front surface of the shorts 4.

The heating device 1 according to the present embodiment includes the pairs P1 to P1.
Since the heat generating portions of P3 are formed so as to be in contact with each other and can be bonded together, when not in use, the heat generating portions can be folded into a compact form. Further, each pair P1 to P3 is connected to each other at the connecting portions D1 and D2 therebetween. Since it can be folded and stacked, it can be folded into a more compact form. Therefore, the packaging state before use can be reduced in size, which is convenient for carrying, transporting, and storing. Further, each of the adhesive surface a and the release surface b
Because it is made to be able to be peeled and adhered by being in contact with each other, it can be folded compactly without intervening release paper when not in use, and in use,
The trouble of removing the release paper can be omitted.

In use, a part of the heating tool 1 is

At this time, since the adhesive surface a is adhered to the back surface of the front portion of the shorts 4, the heating tool 1 is used when the shorts 4 are raised or lowered.
From the heated portion is prevented.

Further, in the heating device 1 of the present embodiment,
Since the heat-generating portion A having the adhesive surface a and the heat-generating portion B having the release surface b are arranged so as to form different rows, the adhesive surfaces a stick to each other during use. The heating device 1 can be easily and reliably fixed to a heated portion such as the lower abdomen. Furthermore,
Since there is no adhesive surface a at the center, the slack of the cloth when raising and lowering the shorts 4 interferes in the area, and the raising and lowering of the shorts 4 can be performed smoothly.

In addition, since the subdivision heating element fits the unevenness of the lower abdomen of the body, it is possible to reduce a sense of incongruity (the heating parts can easily move in all directions). Since the mounting shape and the mounting position can be changed, it is easy to hit a place where the user wants to mount, especially a painful part.

Although the preferred embodiment of the heating device of the present invention has been described above, the present invention is not limited to the above embodiment, and can be appropriately modified. For example, the shape of each heat generating portion is not limited to a triangular shape, but may be an arbitrary shape such as a semicircular shape or a rectangular shape. Further, the shape of the pair of the heat generating portion A and the heat generating portion B is preferably line-symmetric with respect to the connecting portions C1 to C3 between the two as in the above embodiment. The heat generating portion B may be asymmetric. However, the heating element B is larger than the adhesive surface a of the heating element A.
