リウム、活性炭等からなる酸化助剤を主成分とし、大気
中の酸素との接触によって発熱する発熱体を使用したも
のとして、一般に使い捨てカイロと呼ばれているものが
あり、近年、市場に広く出廻っている。Disposable body warmers are generally disposable body warmers that are mainly composed of oxidized metals such as iron powder or aluminum powder, and oxidation aids such as water, sodium chloride, and activated carbon, and that use a heating element that generates heat upon contact with oxygen in the atmosphere. There is something called , which has been widely available on the market in recent years.
このような使い捨てカイロは、粉粒状体とじた上記発熱

接触させ発熱させている。Such a disposable body warmer is one in which the above-mentioned powdered heating element is filled in a breathable inner bag, and this is then sealed and stored in a non-breathable outer bag. 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.

った。However, with conventional heating elements, the metal to be oxidized, which is the heat source, and the oxidation aid, which is the reaction accelerator, are concentrated at the bottom of the bag, resulting in uneven heat generation, and the entire surface of the inner bag has a uniform temperature. In addition, there was a problem that the metal to be oxidized and the oxidation aid gathered together after heat generation and became a lump, which deteriorated the contact feel during use. [Problem to be solved by the invention] Therefore, this invention This is an attempt to solve 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 the contact feeling deteriorates during use. [Means for solving the problem] Therefore, in this invention, in a heating element which mainly consists of an oxidized metal and an oxidizing auxiliary agent and generates heat by contact with oxygen, the oxidizing auxiliary agent is formed into a sheet. In 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.

て実施することができる。In the figure, (1) is a heat source pack using the heating element (2) of the present invention, and the heating element (2) is placed inside the breathable inner bag (3).
2) and then sealed and stored in an air-impermeable outer bag (4). The inner bag (3) is made of cloth, breathable resin, or other appropriate breathable material, and the outer bag (4) is made of a non-breathable heat-fusible synthetic resin film such as polyethylene, polypropylene, etc. Other appropriate non-air permeable members may be used. In addition, inner bag (3) and outer bag (4)
is not limited to a bag as long as it can surround the heating element (2), but may also be a foreskin sheet (3) or (4) as shown in FIG. The heating element (2) mainly consists of a metal to be oxidized (5) and an oxidation aid (6), and in this example, the metal to be oxidized (5) in the form of a foil is folded back in a zigzag pattern, and a sheet is formed in between. The metal to be oxidized (5), which is a laminate sandwiching the oxidation aid (6), includes iron, aluminum, zinc,
Magnesium or the like is used, and it is preferable to form it into a foil shape as in the example, but it can also be formed into a fibrous shape, a net shape, or any other suitable shape.

他適宜のものとすることができる。The oxidation auxiliary agent (6) is formed into a sheet by holding moisture and chloride in a porous member. In this example, coconut shell activated carbon or activated carbon fiber made from phenol resin was used as the porous member, but other appropriate materials such as polymer absorbent material, nonwoven fabric, super absorbent resin, fiber material, vermiculite, wood chips, etc. can be taken as a thing.

で発熱の持続時間が長い等の優れた効果を有するSince this invention is configured as described above, the inner bag (3
), the oxidizing aid (6) is not concentrated at the bottom of the bag, so heat generation is uniform, and the heat is evenly transmitted to the surface of the inner bag (3), so that the entire surface of the inner bag (3) is heated to an appropriate level. Since the oxidation aid (6) does not aggregate with the metal to be oxidized (5) and form a lump, the contact feeling does not deteriorate during use, and furthermore, there is no possibility of localized violent reaction force. It has excellent effects such as a long duration of heat generation because there is no
