In addition, it is necessary to manage the storage of these materials and the subdivision at the time of bodily sensation, and there is a problem that involves extremely complicated work.

  For such a problem, the applicant consists of a sealed bag-like material including a first chamber containing hygroscopic exothermic fibers and a second chamber containing water, where the first chamber and the second chamber are weakly sealed portions. By winding the sealed bag-like material from the end, the water in the second chamber is pushed toward the weak seal portion to break the seal in the weak seal portion, and the water in the second chamber is broken. And a hygroscopic exothermic fiber heating kit that is configured so that the hygroscopic exothermic fibers in the first chamber can be brought into contact with each other (see Patent Document 1).

  This heating element sensation kit can experience the heat generation of moisture-absorbing exothermic fibers without touching the material, but it requires the outer sealed bag-like material to be wound from the end, so it is very troublesome for the sensation, and the weak seal part There was a problem that could not immediately grasp the destruction situation.
