本発明は、微細気孔を存する収納袋を用いてなる収納袋
に、空気の存在下で発熱する発熱組成物を封入した使い
すてカイロならびにその製造方法に間するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention provides a disposable body warmer in which a storage bag made of a storage bag having micropores is filled with a heat-generating composition that generates heat in the presence of air; The manufacturing method is explained below.
鉄粉、水、保水剤及び酸化助剤等からなる発熱組成物は
、点火を必要とセず空気と接触するだけで簡便に発熱す

ィルムを発熱組成物収納袋の袋材として利用できること
も例示されている（特開平１−２１８４４７号）。The exothermic composition consisting of iron powder, water, water retention agent, oxidation aid, etc. generates heat simply by contacting with air without requiring ignition, so the exothermic composition was stored in a bag with ventilation holes. Disposable body warmers are widely used. Currently, many single-use body warmers that are widely used use a method of punching needle holes in a bag material made of non-woven fabric layered with polyethylene as a sealant. It is also exemplified that it can be used as a bag material for storage bags (Japanese Patent Application Laid-Open No. 1-218447).
しかし、このような微細気孔を有するフィルムを用いた
袋材で製造したカイロは、袋材のンーラントが微細気孔
を多数有しているために、シール時にエツジ切れを起こ
し易いという欠点があり、その結果、製造品は発熱不良

った。However, body warmers manufactured using bag materials using films with such fine pores have the disadvantage that the edges of the bag material tend to break during sealing due to the large number of fine pores in the bag material. As a result, the manufactured products suffered from problems such as overheating, expansion of the storage bag, and leakage of contents.

るものである。In order to solve the above-mentioned problems, the inventors of the present invention have conducted intensive studies and found that when enclosing a heat-generating composition into a storage bag having fine pores, the edges of the rotary heat-sealing bar of the filling machine, particularly the bag, are formed. The inventors discovered that it was possible to manufacture a body warmer with no edges by sealing the edges with a plain color, and completed the present invention. In other words, if the entire surface of the heat seal bar was made plain, edge breakage would not occur, but the bag material would tend to slip off on the rotating bar, resulting in incomplete forwarding of the bag material, which was unsuitable for the manufacturing process. It has become clear that according to the method of the present invention, the problem of edge breakage can be solved without any trouble in the manufacturing process. The present invention relates to a high-quality disposable body warmer with no broken edges manufactured by such a method, and a useful manufacturing method thereof.

る。Reference numeral 2 denotes a heat generating composition storage bag for storing the heat generating composition 1, and a bag material having fine pores is used. Examples of the microporous film include thermoplastic sheets or films made of microporous polyethylene, polypropylene, polyurethane, or plastics and rubbers made of flexible modified materials, and these can be used alone. Commercially available products include Tyvek (manufactured by DuPont), Cellpore (manufactured by Mikiki Kagaku), NF Receipt (manufactured by Tokuyama Soda), and Obcel (manufactured by Sanso Kako). , Rubicel (manufactured by Toyo Polymer), etc., and Preslon (manufactured by Nitto Denko) is a laminated nonwoven fabric.

3 is suitable for the width of 0.5 mm to 8 mm, and it is preferable to set it wide as long as it does not interfere with the forward feeding of the bag material in the manufacturing process. Although shown as an example, it does not necessarily have to be a three-sided seal, and of course a four-sided seal may also be used.

Each is composed of a patterned portion 5 and a plain portion 6. Note that the shape and size of the seal bar are not limited to these, and the pattern and design engraved on the seal bar are also completely arbitrary. In FIG. 3, plain portions are provided at both ends of the heat seal bar, but this is because the heat seal bar is cut into two pieces, upper and lower, at the center for sealing.
