Problems solved by technology

Therefore, in this heating pack, there is the same inconvenience as that of the body pad described in the aforementioned Patent Document 2.
Moreover, in this heat generating bag, the air-permeable adhesive surface as the inflow surface of the air faces the underwear, and therefore, depending on the type of cloth of the underwear, the air may not be sufficiently supplied.
Furthermore, in order to ensure air permeability, if the application area of ​​the adhesive is controlled, there are cases where sufficient adhesive force cannot be obtained.

Abstract

A heating device (10) which comprises: a first surface (13) located on the side near to the skin of a wearer and having air permeability; a second surface (14) located on the side remote from the skin of the wearer; and a heating part (11) disposed between the two surfaces. It further has, disposed on the outside of the second surface (14), a pressure-sensitive adhesive part (16) for fixing the heating device (10) to a garment. The first surface (13) is made of a nonwoven fabric (13b) having surface irregularities. The nonwoven fabric (13b) is composed of a first fibrous layer (21) including one side and a second fibrous layer (22) including the other side, the two layers (21) and (22) being partly bonded to each other so that the first fibrous layer (21) has many protrusions (24) and recesses (25). That one side is used as the first surface (13).

Description

technical field [0001] The present invention relates to a heater for body warming, in particular to a heater for relieving menstrual pain. Background technique [0002] Various heaters are known that enclose a heat-generating material in an air-permeable flat bag, and use the heat generated by the heat-generating material to heat the body. For example, the present applicant has proposed a portable body warmer, which has a body of the body made of a surface layer, a back layer, and a heating element interposed between the surface layer and the back layer; A fixing piece provided on the body of the body heater so that the upper edge of the body of the body heater extends to the outer surface and is attached to shorts (underwear) (refer to Patent Document 1). Adhesive is applied to the body of the body warmer and the fixing piece, and the body of the body warmer is attached to the outer surface of the shorts by using the adhesive, and the fixing piece is folded into the inner ...
