【Example】

 A first embodiment of the heating volatilization tool according to the present invention will be described. As shown in FIG. 1, FIG. 2 and FIG. 3, the container body 1 has a hollow shape from an upper container 2 and a lower container 3, and the upper container 2 has a vent hole 7 that vertically communicates with the outer peripheral side. A plurality of substantially circular plate-shaped upper walls 4 each having a circular concave-shaped mounting portion 8 which is recessed from the outer peripheral side on the center side of the upper wall 4 and the peripheral edge of the upper wall 4. A generally frustoconical shape in which a peripheral wall 5 that is integrally provided and that gradually expands downward and an annular body 6 that is integrally provided at the lower end of the peripheral wall 5 and that projects to the outer peripheral side open downward Further, the lower container 3 has a substantially circular plate shape integrally formed with an annular holding portion 11 protruding upward on the inner peripheral side upper surface, and the outer peripheral side of the lower container 3 and the upper container. The second annular body 6 is closely attached. Then, a carrier 9 that vaporizes the drug impregnated by being heated on the mounting portion 8 is mounted and fixed. The drug impregnated in the carrier 9 is a volatile substance such as aroma, deodorant, deodorant, insecticidal and sterilizing. Then, the chemical reaction type exothermic agent 10 is housed and held in the inner periphery of the holding portion 11 of the lower container 3, and the chemical reaction type exothermic agent 10 is housed in the container body 1. The chemical reaction type exothermic agent 10 generates heat upon contact with air. Further, the chemical reaction type exothermic agent 10 is provided on the lower surface of the mounting portion 8 of the upper wall 4 while forming a slight gap, and the chemical reaction type exothermic agent 10 and the vent hole 7 of the upper wall 4. It is provided so that the space 12 is formed between the space 12 and the place where the space is provided. Then, a gas barrier release paper 13 is adhered to the upper wall 4, and the gas barrier release paper 13 shields the vent hole 7 provided in the upper wall 4 to seal the container body and to place it thereon. By sealing the carrier 9 fixed to cover the portion 8 to prevent the chemical reaction type heating element 10 housed inside the container body 1 from contacting with air, the drug in the carrier 9 spontaneously volatilizes. It is designed to prevent A heat insulator 14 is fixed to the entire lower surface of the lower container 3 of the container body 1. The heat insulator 14 is glass wool, rock wool, alumina foil, or the like. Then, an adhesive 15 is applied to the lower surface of the heat insulating body 14, and a bottom release paper 16 is further attached.

Next, a method of using the heating volatilization tool will be described. The bottom release paper 16 is peeled off from the lower surface of the lower container 3, and the container body 1 is fixed to the installation location with the adhesive 15. Then, the gas barrier release paper 13 attached to the upper wall 4 of the upper container 2 is peeled off to expose the carrier 9 fixed to the mounting portion 8 and to open the ventilation hole 7. By opening the vent hole 7, air is introduced into the container body 1 from the outside, the chemical reaction type heating element 10 is brought into contact with air, and a chemical reaction is caused to generate heat. The chemical reaction type heating element 10 heats the carrier 9 fixed to the mounting portion 8 to volatilize the drug impregnated from the carrier 9.

Next, the function and effect of the first embodiment will be described. By providing the vent hole 7 through which air flows into the container body 1 in the upper wall 4 of the container body 1 in this way, it is possible to prevent leakage of the chemical reaction type exothermic agent 10 without providing a special filter. The number of parts is reduced and the cost is reduced. Further, by providing the heat insulator 14 on the lower surface of the lower container 3, it is possible to prevent the lower side of the container body 1 from becoming hot and to reduce the heat loss of the chemical reaction type exothermic agent 10. The bottom release paper 16 is peeled off from the lower surface side of the lower container 3, the container body 1 is fixed by the adhesive 15, and the carrier 9 is also fixed by the adhesive or a locking tool provided on the upper container 2 to be placed at an arbitrary place. It can be installed reliably. Further, at the time of use, by simply peeling off the gas barrier release paper 13 attached to the upper wall 4 of the upper container 2, the vent hole 7 can be opened to cause the chemical reaction type heat generating agent 10 to generate heat. The drug can be volatilized from the carrier 9 by exposing the carrier 9 fixed to the placing portion 8. Further, a space 12 having a volume equal to or larger than that of the chemical reaction type heating element 10 is formed between the chemical reaction type heating element 10 inside the container main body 1 and a portion of the upper wall 4 where the vent hole 7 is provided. With such a configuration, the entire outer periphery of the chemical reaction type heating element 1 comes into contact with air, and the chemical reaction type heating element 1 can efficiently generate heat.

In the heating volatilizer configured as described above, it is necessary to control the surface temperature of the mounting portion 8 on which the carrier 9 is mounted. This is because the number of the ventilation holes 7 provided in the upper wall 4 is large. This can be achieved by variously changing the (opening area) or the thickness of the mounting portion 8. When the number of ventilation holes 7 is reduced to reduce the inflow of air into the container body 1, the chemical reaction type exothermic agent 10 Is less in contact with air, the heat generation temperature is low, and the surface temperature of the mounting portion 8 is low. On the other hand, when the number of the vent holes 7 is increased, the chemical reaction type exothermic agent 10 is more likely to come into contact with the air, and the surface temperature of the mounting portion 8 is increased. The heat generation time is long when the number of ventilation holes 7 is small and short when the number of ventilation holes 7 is large. It is possible to control the surface temperature of the mounting portion 8 by changing the number of the ventilation holes 7 as described above or by the gap between the mounting portion 8 on which the carrier 9 is mounted and the chemical reaction type heat generating agent 10. Is. That is, the clearance can be set to a target surface temperature by taking an arbitrary distance from zero. Further, for example, when a plastic plate is used for the container body 1, the surface temperature of the mounting portion 8 can be changed from 30 ° to 150 ° by arbitrarily changing the thickness of the mounting portion 8 in the range of 0.1 mm to 2 mm. It is preferable to set it within the range, and it becomes possible to set the surface temperature of the mounting portion 8 according to the drug impregnated in the carrier 9. In addition, when the composition described in Japanese Patent Publication No. 54-37067 is used as the chemical reaction type exothermic agent 10 used in this example, it is contained inside when the chemical reaction type exothermic agent 10 is heated. The generated water becomes water vapor, and the water vapor is volatilized to the outside from the inside of the container body 1 through the ventilation holes 7. As a result, the volatilization of the drug on the carrier 9 is promoted by the volatilization of water vapor, and the volatilization can be favorably performed. The form of the chemical reaction type exothermic agent 10 may be tablet, granule, or powder.

Next, a second embodiment according to the present invention will be described. As shown in FIG. 4, the container body 1 is hollow from the upper container 2 and the lower container 3, and the upper container 2 has a substantially truncated cone shape similar to that of the first embodiment described above, and has an upper wall. 4, a mounting portion 8 is formed as in the first embodiment, a carrier 9 is fixed to the mounting portion 8, and a plurality of ventilation holes 7 are provided.

The lower container 3 is integrally provided with a lower projecting portion 17 projecting downward in an annular shape, and a heat insulating body 14 having a substantially circular plate shape is provided in the lower projecting portion 17, and an annular holding projecting upward is provided on an upper surface of the heat insulating body 14. The portion 14a is integrally formed, and the chemical reaction type heating element 10 similar to that of the first embodiment is placed inside the holding portion 14a. Then, the gas barrier release paper 13 is adhered to the entire upper container 2, the adhesive 15 is applied to the lower end surface of the lower protrusion 17 of the lower container 3 as in the first embodiment, and the bottom release paper is further applied. 16 is attached.

With such a configuration, it is possible to obtain substantially the same operational effects as the first embodiment, and by providing the ventilation hole 7 in the upper wall 4 and the peripheral wall 5 of the upper container 2, An air flow is generated from the ventilation hole 7 provided in the peripheral wall 5 to the ventilation hole 7 provided in the upper wall 4 by the heat rising air flow in the container body 1 to improve the inflow of air into the container body 1. The heat generation of the chemical reaction type heating element 10 can be improved.

Next, a test example of the surface temperature of the mounting portion 8 to which the carrier 9 is fixed according to the present invention will be described. Using the heating volatilizer shown in the first embodiment, the container body 1 has an outer diameter of the upper wall 4 of 26 mm, a lower outer diameter of the peripheral wall 5 of 33 mm, and a thickness of a mounting portion of the upper wall 4 of 0.2 mm.

Then, as a comparison, the chemical reaction type heat-generating agent 10 alone of the tablet 1.3 g was caused to generate heat, and the surface temperature of the chemical reaction type heat-generating agent 10 at this time was measured (D shown in FIG. 6). The results are shown in FIG. As is clear from the results shown in FIG. 6, the larger the amount of air contacting the chemical reaction type exothermic agent 10, the higher the exothermic temperature of the chemical reaction type exothermic agent 10, and the shorter the period of time.

Next, the volatilization test of the fragrance in the present invention will be described. Using the heating volatilizer shown in the first embodiment, the container body 1 has an outer diameter of the upper wall 4 of 26 mm, a lower outer diameter of the peripheral wall 5 of 33 mm, and a thickness of the mounting portion 8 of the upper wall 4 of 0. The length is 2 mm, 1.3 g of the chemical reaction type exothermic agent 10 tablets, and 16 vent holes 7 having a diameter of 1.3 mm are provided on the upper wall 4.
