Oxidizable metals such as iron powder and aluminum powder, water,
In recent years, there is a type of disposable body warmer that uses an oxidizing agent such as sodium chloride or activated carbon as its main ingredient and a heating element that generates heat when it comes into contact with oxygen in the atmosphere. It is widely distributed.

いる。 Such a disposable body warmer is one in which the heating element in the form of powder is filled in a breathable interior and then sealed and housed in a non-breathable exterior. When in use, the outer bag is opened and the inner bag filled with a heating element is brought into contact with the atmosphere and generates heat.

用の際に接触感が劣化するという問題点があつ
た。 However, in conventional heating elements, the metal to be oxidized, which is the heat source, and the oxidation aid, which is the reaction accelerator, are concentrated in the lower part of the bag, causing uneven heat generation.
There was a problem in that the temperature of the entire surface of the inner bag was not uniform, and that the metal to be oxidized and the oxidation aid gathered together after heat generation to form a lump, which deteriorated the contact feel during use.
〔発明が解決しようとする問題点〕
そこで、この発明は上記従来例の発熱体が有す

る。[Problems to be Solved by the Invention] Therefore, the present invention solves the problems of the conventional heating element described above, namely, that the entire surface of the inner bag does not have a uniform temperature, and that there is a feeling of contact during use. This is an attempt to solve the problem of deterioration.
そのため、この発明では、被酸化金属と酸化助

Therefore, in the present invention, the oxidizing aid is in the form of a sheet in a heating element that contains the metal to be oxidized and the oxidizing aid as main components and generates heat upon contact with oxygen.
その結果、袋内において酸化助剤は袋の下部に
片寄ることなく、又被酸化金属と集結して塊とな

As a result, within the bag, the oxidizing auxiliary agent was not concentrated at the bottom of the bag, nor was it collected with the metal to be oxidized to form a lump.

み込んだ積層体としている。 In the figure, 1 is a heat source pack using a heating element 2 of the present invention, in which a breathable inner bag 3 is filled with the heating element 2, and this is further sealed and stored in a non-breathable outer bag 4. are doing. The inner bag 3 may be made of cloth, breathable resin, or other appropriate breathable material, and the outer bag 4 may be made of non-breathable heat-fusible synthetic resin film such as polyethylene or polypropylene.
Other appropriate non-air permeable members may be used. Note that the inner bag 3 and the outer bag 4 are not limited to bags as long as they can surround the heating element 2, but may also be foreskin sheets 3', 4' as shown in FIG. The heating element 2 has a metal to be oxidized 5 and an oxidizing aid 6 as its main components, and in this embodiment, the metal to be oxidized 5 in the form of a foil is folded back in a zigzag pattern, and a sheet of the oxidizing aid 6 is sandwiched between them. It is my body.
前記被酸化金属５は、鉄、アルミニウム、亜
鉛、マグネシウム等が使用され、実施例のように
箔状とするのが好ましいが、繊維状、網状等、そ
の他適宜形状として実施することができる。 The metal to be oxidized 5 is made of iron, aluminum, zinc, magnesium, etc., and is preferably in the form of a foil as in the embodiment, but may also be in the form of a fiber, a net, or any other suitable shape.
前記酸化助剤６は、多孔性部材に水分及び塩化

ることができる。 The oxidation auxiliary agent 6 is made into a sheet-like form by retaining moisture and chloride in a porous member. In this example, coconut shell activated carbon or activated carbon fiber made from phenolic resin was used as the porous material, but other materials such as polymer absorbent material, nonwoven fabric, super absorbent resin, fiber material, vermiculite, wood chips, etc. It can be any appropriate.

Since this invention is configured as described above,
In the inner bag 3, the oxidizing aid 6 is not concentrated toward the bottom of the bag, so heat generation is uniform, and the heat is uniformly transmitted to the surface of the inner bag 3, so that the entire surface of the inner bag 3 has an appropriate temperature. Since the oxidizing aid 6 does not aggregate with the metal to be oxidized 5 to form a lump, the contact feeling does not deteriorate during use, and furthermore, the duration of heat generation is shortened because no intense reaction force occurs locally. It has excellent effects such as long length.
