  FIG. 3 is a perspective view showing a state in which the heat insulation pack 18 (the heat storage body 12 and the bag body 14) is folded. As shown in FIG. 3, in this embodiment, the heat insulation pack 18 is used in a folded state. When the heat insulation pack 18 is folded, the left portion 18a and the right portion 18b sandwiching the central portion in the length direction of the heat insulation pack 18 are folded in two toward the upper surface side. Therefore, in the state in which the heat insulating pack 18 is folded, the diffusion ports 32a, 32b, and 32c for diffusing the gas are formed on the upper surface, the front surface, and the rear surface in FIG. 3, and the other surfaces are airtight. The first sheet 28 is covered. In addition, the two dashed-dotted lines in FIG. 2 (A) have shown the folding line when each of the left side part 18a and the right side part 18b is folded.

  A holding body 16 shown in FIGS. 1 (A) and 1 (B) holds a heat insulating pack 18 (that is, a bag body 14 containing a heat storage body 12), and as shown in FIG. 1 (B), a heat insulating pack. 18 has a first space S1 for accommodating 18 and a second space S2 for accommodating herb 36 (FIG. 5). The holding body 16 of the present embodiment is configured by stitching a fabric having air permeability into a bag shape, and the upper portion of the holding body 16 is configured in a double structure having an inner portion 38a and an outer portion 38b. ing. The upper part of the holding body 16 is a body proximity part 38 that is air permeable and is arranged close to the body, and this body proximity part 38 includes the herb storage part 40 that constitutes the second space S2.

Therefore, as shown in FIG. 5, in the state where the herb 36 is accommodated in the herb accommodating part 40 of the body proximity part 38, the gas diffused from the radiation port 32a (FIG. 3) is applied to the herb 36 and the components are extracted. can do.

  When using the heat retainer 10 shown in FIG. 1, first, the heat storage body 12 of the heat retainer 10 is heated in a microwave oven. At this time, the heat insulating pack 18 may be removed from the heat insulating device 10 and only the heat insulating pack 18 may be heated by the microwave oven, or the entire heat insulating device 10 may be heated by the microwave oven. Subsequently, the heat retaining device 10 is fixed to the body such that the body proximity portion 38 is close to the body. When the gas generated by the evaporation of the water 20 and the volatile component 22 shown in FIG. 2 (B) is released from the emission ports 32a, 32b, and 32c, the gas is contained in the herb 36 contained in the herb container 40. Then, it passes through the body proximity part 38 and is given to the body. This warms the body. When the temperature of the heat storage body 12 decreases, the heat storage body 12 is heated again in the microwave oven.

  When the warmer 10 is not used, it is desirable to store the warm pack 18 in a refrigerator in order to prevent the heat storage body 12 from deteriorating. Since salt is mixed in the water 20 (FIG. 2B) of the heat accumulator 12, the water 20 hardly freezes and the heat retaining pack 18 is hard to harden even if the heat retaining pack 18 is put in the freezer compartment. Therefore, the heat insulation pack 18 cooled in the freezer compartment can be used as a cold insulator.

  According to the present embodiment, the following effects can be achieved by the above configuration. That is, as shown in FIG. 2B, at least a part of the bag body 14 (the first sheet 28) is formed of a material having airtightness, so that the water 20 absorbed by the absorbent 24 and the volatilization are obtained. The sex component 22 is not easily diffused to the outside of the bag body 14. Therefore, when the temperature of the heat storage body 12 falls, it can be continuously used by heating it with a microwave oven or the like.

  As shown in FIG. 1 (B), the gas generated by the evaporation of the volatile component 22 (FIG. 2 (B)) extracted from the herb can be diffused together with the water vapor from the diffusion port 32a. Since it can be applied to the body, the effect of hyperthermia can be enhanced.

  The volatile component 22 shown in FIG. 2 (B) is extracted from at least one herb selected from mugwort, loquat leaves, dokudami, lavender, rosemary and rose, so these herbs available in Japan are used. Thus, the heat insulator 10 can be easily manufactured.

  In the absorbent material 24 shown in FIG. 2 (B), the polymer absorbent material 24b having a large molecular weight is used. Therefore, the heat storage body 12 is not easily cooled, and the warmth can be maintained for a long time.

  Since the heat storage body 12 shown in FIG. 2 (B) has powdery bamboo charcoal 26 or charcoal (not shown), it is possible to suppress the propagation of bacteria and enhance the heat retaining effect. Moreover, since the bamboo charcoal 26 or charcoal is in powder form, even when heated with a microwave oven, the bamboo charcoal 26 or charcoal can be prevented from being heated excessively.

  As shown in FIG. 5, the body proximity part 38 has a herb container 40 that houses at least one herb 36 selected from mugwort, loquat leaves, dokudami, lavender, rosemary and rose. Since the gas diffused from the radiation port 32a shown can be applied to the herb 36, components can be extracted from the herb 36 and applied to the body.

  In carrying out the present invention, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the object of the present invention. FIG. 6 is a perspective view showing a configuration of another bag body 50. FIG. 7 is a perspective view showing a configuration of another holding body 60.
