Provided is a heating body that can be worn on the body, for example, without being affixed thereto, which can be manufactured at high speed using a conventional rotating heat seal roller, with which a part that is worn has adequate strength for use with a hand or the like inserted thereinto, and which is safe and convenient to use. Also provided is a method for manufacturing the same. One example of a mode of embodiment of the present invention is a heating body, and a method for manufacturing the same, in which an exothermic composition which generates heat in the presence of air is accommodated in a bag body formed by heat sealing a one-surface side laminated base material comprising a first base material and a second base material and a covering material at peripheral edge portions thereof, characterized in that: one surface of the first base material is a non-woven fabric layer, and the other surface thereof is a heat sealable resin layer; the second base material is a sheet in which an olefin-based non-woven fabric layer and a resin film are laminated using an olefin-based resin; the first base material and the second base material are capable of forming, in a part thereof surrounded by a peripheral edge portion, a space into which a body part can be inserted or held; and in a heat seal part of the bag body peripheral edge portion, the heat sealable resin layer of the first base material and the non-woven fabric layer of the second base material are joined together, and the resin film of the second base material and the covering material are joined together.
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 a pressure-sensitive 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 a pressure-sensitive 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.
A heat-generating material, which can follow the extensions and twists of the body in multiple directions and exhibits a good fitting, and a method for producing the heat-generating material. A heat-generating material provided with a fixing part which is positioned lateral to a heat-generating part, characterized in that a linear cut inclined with respect to the anteroposterior direction of the fixing part is formed between the heat-generating part and the fixing part.
Provided is an exothermic body capable of following extensions and twists in a plurality of directions of a body and having a good sense of fit, and also provided is a method for manufacturing the exothermic body. The exothermic body includes an adhesive portion in the lateral direction of an exothermic portion and is characterized in that: a linear cut is provided between the exothermic portion and the adhesive portion, the linear cut being tilted with reference to a front-rear direction of the adhesive portion; and at least one end of the linear cut is bent. This enables the exothermic body, even when being attached to each part of a body or the like, to follow motions including extensions and twists in a plurality of directions, thereby preventing the exothermic body from dropping. Since the exothermic body can extend in the plurality of directions, there is no sense of discomfort, such as being pulled in a specific direction, when the exothermic body is attached, so that a good sense of fit to body movements can be obtained. In addition, the inner periphery surface of a portion formed when the cut is widened becomes a curved shape, so that there is no sense of discomfort even if the exothermic body contacts the skin.
