の膨張、内容物の漏れを生じるという問題があった。An exothermic composition consisting of iron powder, water, a water retention agent, an oxidation aid, etc., generates heat simply by contacting with air without the need for ignition, so the exothermic composition contained in a bag having a vent hole should be used. Cairo is widespread. In many of the widely used hand warmers currently in use, a bag material in which polyethylene is laminated as a sealant on a non-woven fabric is used to form a needle hole, but in recent years, a film having fine pores has a heat generating composition. It is also exemplified that it can be used as a bag material for an object storage bag (JP-A-1-218447). But,
Cairo manufactured with a bag material using a film having such fine pores, because the sealant of the bag material has a large number of fine pores, there is a drawback that edge breakage easily occurs at the time of sealing, as a result, The manufactured products had problems such as defective heat generation, expansion of the storage bag, and leakage of contents.

係るものである。In order to solve the above problems, as a result of intensive studies by the present inventors, when encapsulating the exothermic composition in a storage bag having fine pores, an edge portion of a rotary heat seal bar of a filling machine, particularly a bag is formed. The present invention has been completed by finding that it is possible to manufacture a body warmer without edge breakage by sealing the edge part and then performing a sealing process. In other words, when the entire surface of the heat seal bar was plain, no edge breakage occurred, but the bag material easily slipped on the rotating bar and the advance of the bag material was incomplete, which was not suitable for the manufacturing process. According to the method of the invention, it became clear that the problem of edge breakage can be solved without any trouble in the manufacturing process. The present invention relates to a useable warmer which is manufactured by such a method and has excellent edge-free quality, and a useful manufacturing method thereof.
