example 1
[0391] The heat generating body for heating a foot shown in FIG. 1 is a heat generating body for heating a foot having the shape of the entire foot, having a heat generating component sandwiched between a base material and a covering material, And the base material and the covering material are sealed 6 at a width of 10 mm on the periphery of the heat generating body component 1A.
[0392] Its cross-sectional diagram is figure 2 shown in . As the base material 3, a corrugated fiberboard liner 3E having a thickness of 100 μm and a laying layer having a thickness of 50 μm and having air-impermeability and water-impermeability, made of metallocene catalyst-produced polyethylene 3B were provided. On base material 3, a non-adhesive heat-generating component with excess moisture is molded on a corrugated fiberboard liner by a mold in direct contact.
[0393] The covering material 4 is made by laminating a porous film 4C with a thickness of about 50 μm on a corrugated fiberboard li...

[0405] exist Figure 4 In the heat generating body for heating the foot shown in the plan view, the non-adhesive heat generating component with excess moisture is molded to increase the arch portion and extend from the arch portion to Example 1 by through-molding The form obtained from the shape of , and said part, except for the non-adhesive heat-generating component with excess moisture, is sealed 6 by adhesive, as in example 1.
[0406] Unlike the base material of Example 1, a rayon-polyester hybrid nonwoven fabric having a thickness of 140 μm and a rayon fiber weight of 60% was laminated on both surfaces of a polyethylene film having water absorption and a thickness of 80 μm instead of paper.
[0407] As the covering material, the same non-adhesive heat generating component with excess moisture and adhesive layer as in Example 1 were used.
example 3
[0409] exist Figure 5 In the heat-generating body for heating feet shown in the plan view of , (a) heat-generating component 1A is formed by through-molding on two areas at the approximate center of the shape as in Example 1, and except having Said part outside the non-adhesive heat-generating component 1A of excess moisture is sealed by bonding 6 . At the approximate center position where the heat generating component 1 is not laminated, the heat generating body for heating the foot can be folded so as to be compact. Since the surface area can be reduced during storage, deterioration of heat-generating components due to splashing of water can be reduced. (b) is a product that has perforated line 7A in the area without heat-generating components to facilitate folding. (c) is a product in which a portion protruding from the arched portion is increased.
[0410] The heat generating body 1 for heating the foot shown in the plan view of FIG. 6 shows Figure 5 (b) The perspect...
