- a large number of short fibers 42 2 protrude from the outer surface 41a of the base sheet 41 in a substantially vertical posture. 1
- a gap is easily formed between the base sheet 41 and the skin via the short fibers 42.
- a urethane-based hot-melt adhesive is used as an adhesive for fixing the short fibers 42 to the base sheet 41, this adhesive has excellent heat resistance. Depending on the temperature of the ki, the short fibers 42 will fall off.
- the large number of short fibers 42 provided on the first surface sheet 4 can exhibit the function of lowering the temperature of water vapor and diffusing the water vapor. There is no need for a thick temperature control layer 32. Therefore, it is possible to supply a large amount of water vapor that also generates the heating element 31 force to the skin.
- the periphery of the right inner heating unit 11 is partitioned by a partition line 21.
- a thin sheet portion 15 is formed outside the partition line 21. That is, the partition line 21 is pressed inside the position so that the first surface sheet 4, the second surface sheet 5, the temperature control layer 32, and the heat insulating layer 33 form the thin sheet portion 15.
- Rei, nare, means a boundary line indicating that.
- the temperature control layer 32 and the heat insulating layer 33 formed of the foamed resin sheet are in close contact with each other in the inner peripheral region having the width dimension Wa inside the partition line 21.
- the heating element 31 is formed so as to prevent the heating element 31 from approaching the lane marking 21.
- the width dimension Wa is, for example, in the range of 0.3 to 5 mm. Providing a region of width dimension Wa prevents the color of the oxide from exuding into the parting line 21 when the metal powder forming the heating element 31 is oxidized to form a red-brown oxide. it can.
- the temperature control layer 32 and the heat insulating layer 33 are not present in the region of the width dimension Wa, the oxide (metal layer) of the metal powder is dissolved in water and pressurized. It is led toward the partition line 21 where the fiber density is high, the periphery of the right inner heating part 11 is reddish brown along the partition line 21, and the user sees the color directly, May feel anxiety or discomfort.
- the temperature control layer 32 and the heat insulating layer 33 that are in close contact with each other inside the partition line 21 have the moisture that is colored by dissolving the oxide toward the partition line 21. Can be prevented. Therefore, the lane marking 21 is unlikely to be reddish brown.
- the effect obtained with the cross-sectional structure of FIG. 5 can be obtained in the same manner also in the lane line 22 of the left inner heating unit 12, the lane line 23 of the right outer heating unit 13, and the lane line 24 of the left outer heating unit 14. Is possible.
- FIG. 6 is a front view of the heating element 1 applied to the face
- FIG. 7 is a side view thereof.
- the warming body 1 includes a right inner heating unit 11, a left inner heating unit 12, a right outer heating unit 13 and a left outer side.
- the heating unit 14 has a heating element 31, which is thick and hard to bend.
- the central deformation part 16 between the right inner heating part 11 and the left inner heating part 12 is easy to bend via the center line ⁇ _0, and the right inner heating part 11 and the right outer heating part 13
- the right side deformation part 17 between the left side heating part 12 and the left side deformation part 18 between the left inner heating part 12 and the left outer heating part 14 are also easily bent.
- each of the right inner heating unit 11, the left inner heating unit 12, the right outer heating unit 13, and the left outer heating unit 14 is independent from each other with respect to the undulating covering face. Can be contacted.
- the warming body 1 when the warming body 1 is placed on the face so that the center line O- ⁇ coincides with the central part of the nose and the mouth, the part of the central deformed part 16 having a relatively wide width is formed. Warming body 1 also folds the nose muscle partial force from side to side. Further, the upper deformation reference point 25a and the upper deformation reference point 25b are located near the upper part of the rib located under the eyes, and the lower deformation reference point 26a and the lower deformation reference point 26b are located on the left and right sides below the jaw. If it appears to be located on both sides (left and right sides slightly below the mouth), the warming body 1 at that time will be undulated on the face from the portions of the right and left slope reference lines L1 and L2. It bends to imitate.
- the right inner heating unit 11 and the left inner heating unit 12 can be in close contact with the buttocks on both the left and right sides of the nose.
- the right inner heating part 11 and the left inner heating part 12 both have a shape in which the width dimension gradually decreases as the upper edge 6 is approached. This makes it particularly easy to adhere.
- the right outer heating unit 13 and the left outer heating unit 14 can be brought into close contact with the ears from the left and right sides of the heel.
- a convex portion 6a is formed at the center line O_O. Water vapor can be supplied to both sides of the nose by the projection 6a hitting the nasal muscles.
- the ventilation portion 27 elongated vertically in the central deformable portion 16 is at a height position that can be opposed to at least the nostril or the mouth, and preferably can be opposed to both the nostril and the mouth. Is in a position. Therefore, it becomes easy to suck outside air through the ventilation part 27, and the user feels breathlessness when heat or water vapor is supplied to the face from each heating part 11, 12, 13, 14. There is nothing.
- FIGS. 8 (a) to (e) and FIGS. 9 (a) to (e) are explanatory views showing an embodiment of the ventilation portion 27.
- FIG. 8 (a) to (e) and FIGS. 9 (a) to (e) are explanatory views showing an embodiment of the ventilation portion 27.
- FIG. 8 (a) to (e) and FIGS. 9 (a) to (e) are explanatory views showing an embodiment of the ventilation portion 27.

- the opening width dimension at the upper end is the maximum value A, and the opening width dimension gradually decreases toward the bottom.
- the opening width of the ventilation portion 27B is large at the portion facing the nostril, breathing through the nostril is easy. Further, since the opening width of the ventilation portion 27B is small at the mouth portion, heat and water vapor supplied to the ridges on both sides of the mouth are difficult to escape from the ventilation portion 27B.
- the ventilation portion 27C shown in Fig. 8 (c) two openings having the same shape and small dimensions as those in Fig. 8 (a) are arranged with an interval in the vertical direction.
- the upper opening faces the nostril and the lower opening faces the mouth, so that breathing can be facilitated and the opening area ( Since it can be made smaller than that of a), the heat and water vapor to be supplied to the face are difficult to escape out of the heating element 1.
- the opening width is the maximum value A at the upper and lower ends, and the opening width dimension force M is narrowed down at the upper and lower central portions.
- the ventilation part 27D also has a large opening width at the part facing the nostril and the part facing the mouth for easy breathing, and the width dimension is narrowed at the center, so the heat to be supplied to the face And water vapor is difficult to escape from the vent 27D.
- the rectangular openings are intermittently arranged in the vertical direction
- the ventilation portion 27F shown in Fig. 9 (a) the circular opening portion has a circular opening portion. They are arranged intermittently in the vertical direction.
- the heating element 1 a plurality of rows of rectangular openings shown in (e) of FIG. 8 and circular openings shown in (a) of FIG. 9 may be formed. The openings may be arranged in a zigzag shape.
- the ventilation portion 27G may be formed by a slit that penetrates the thin sheet portion 15, and like the ventilation portion 27H shown in Fig. 9 (c). Alternatively, it may be formed with a serrated slit or a wavy slit. Furthermore, the ventilation part 271 shown in Fig. 9 (d) In addition, slits may be formed intermittently to prevent water vapor from escaping to the outside.
