ている。<Conventional technology> The main heating substances in disposable body warmers are iron powder, water, salt as a catalyst, activated carbon, and a water-retaining material. In order to prevent shortening of the usage time due to air permeability, the body of the disposable body warmer is wrapped in a plastic film made of polypropylene, polyester, polyethylene, nylon, etc., and oxygen, such as vinylidene chloride, vinyl chloride copolymer, etc. The product is sealed and packaged in an outer bag made of a plastic-coated sheet that does not allow moisture to pass through (commonly known as KOP sheet), and when used, the outer bag is torn and removed.
〈発明が解決しようとする課題〉
しかし、上記外袋は酸素、つまり空気の侵入防止効果は
充分であるが、水分の透過防止度は酸素よりも劣る。こ

が低下する。<Problems to be Solved by the Invention> However, although the above-mentioned outer bag has a sufficient effect of preventing the intrusion of oxygen, that is, air, the degree of prevention of moisture permeation is inferior to that of oxygen. For this reason, approximately lO to I
5-The contained moisture evaporates from the outer bag during long-term storage (3 years or more), shortening the duration of use and reducing the commercial value.

図面において、１は通気性袋に発熱物質が入った扁平な
使い捨てカイロ本体、２は上記カイロ本体を１個宛包装
する前述のＫＯＰシートで製袋した外袋を示す。Embodiments In the drawings, numeral 1 indicates a flat disposable body warmer body containing a pyrogenic substance in an air-permeable bag, and 2 indicates an outer bag made of the above-mentioned KOP sheet for packaging the body warmer body for one piece.
本発明は、この外袋入り使い捨てカイロを複数枚、例え

のである。In the present invention, a plurality of disposable body warmers in outer bags, for example, 10 sheets, are stacked, placed in a storage bag 3 made of a sheet made of a moisture-impermeable material, and then sealed and repackaged.
保存袋３を製袋するシートは、アルミ箔等の金属箔や、

して置く。The sheet used to make the storage bag 3 is made of metal foil such as aluminum foil,
There are also metal-deposited sheets in which fine metal powders such as aluminum, copper, and chrome are layered on plastic films such as polypropylene, polyester, polyethylene, and nylon using a vacuum deposition method. Use a material that does not allow moisture to pass through, such as a metal printed sheet with fine metal powder layered on a film. In order to seal the sheet by heat sealing, a heat sealing film such as a polyethylene film is laminated on the inner surface of the sheet.
そして、使い捨てカイロ本体は水素を発生し、この水素
が外袋２から出るため、保存袋３には水素を外に逃すた
めの小孔４を開設して置く。小孔５の面積は保存袋４の
全表面積の５％以内にする。Since the disposable body warmer body generates hydrogen and this hydrogen comes out from the outer bag 2, a small hole 4 is provided in the storage bag 3 to let the hydrogen escape to the outside. The area of the small holes 5 should be within 5% of the total surface area of the storage bag 4.
こうして保存袋４に外袋入すの複数枚の使い捨てカイロ

分を外に蒸散する面積は極めて少なくなるため、外袋に
入っている各使い捨てカイロ本体の水分の蒸散が大幅に
防止できる。又、同時にカイロ本体が発生し、外袋から
出る水素は保存袋の小孔５から外に逃げるため、長期間
の保存中に保存袋が水素でパンパンに膨張し、破裂する
こともない。In this way, when multiple disposable body warmers are stacked in the outer bag in the storage bag 4, the bottom surface of the outer bag of the body warmer stacked on top and the top surface of the outer bag of the body warmer stacked below take up most of the area. The upper surface and the lower surface of the storage bag that does not allow moisture to permeate are in close contact with the upper surface of the outer bag of the topmost tier body warmer and the lower surface of the outer bag of the lowermost tier body warmer. Therefore, the surface area of each outer bag from which water evaporates to the outside becomes extremely small, so that evaporation of water from each disposable body warmer body contained in the outer bag can be significantly prevented. In addition, since the body warmer is generated at the same time and the hydrogen coming out of the outer bag escapes from the small hole 5 of the storage bag, the storage bag will not expand and burst due to hydrogen during long-term storage.
