DETAILED DESCRIPTION OF THE INVENTION
Embodiments according to the present invention will be described below in detail with reference to the drawings. In the water heating exothermic container 1 shown in FIG. 1, a cylindrical self-heating container 3 containing a water heating exothermic substance is detachably accommodated in an upper open type container 2. The upper open container 2 is formed of a synthetic resin, paper, rubber, metal, wood or the like having waterproof properties.
[0014]
The upper opening of the upper open container 2 is closed by a peelable container seal 7 and further covered by a paper lid 8 and an upper lid 9. An upper recess 6a to which a sealed container 4 described later is mounted is provided at the lower part of the upper open container 2, and further, a lower recess to which an end of the self-heating container 3 is mounted inside the upper recess 6a. 6b is provided. The lower end periphery of the upper recess 6a and the upper end periphery of the lower recess 6b are connected to the bottom surface 2a of the upper open container 2 by an inclined surface 6c having an angle θ. And the protrusion part 5 is mounted in the upper-end periphery part of the lower stage recessed part 6b. FIG. 2 shows a plan view of the upper open container 2 when the container seal 7 in FIG. 1 is peeled off.
[0015]
As shown in FIGS. 1 and 2, an annular sealed container 4 containing a predetermined amount of water is detachably fitted to the upper side surface of the self-heating container 3. Here, the upper surface opening of the sealed container 4 is closed by the film 10. On the other hand, the lower end of the self-heating container 3 is mounted in the lower recess 6b.
[0016]
Hereinafter, the operation of the present embodiment will be described.
In using the hydrothermal exothermic container 1 in FIG. 1, first, the upper lid 9 and the paper lid 8 are removed from the upper open container 2, and the container seal 7 that closes the upper surface of the upper open container 2 is peeled off. Next, the self-heating container 3 and the sealed container 4 fitted to the self-heating container 3 are taken out from the upper open container 2.

There is no worry of adding too much water. Moreover, since the inclined surface 6c has the inclination with respect to the surface of the film 10, the surface of the film 10 is not sealed, but the water in the airtight container 4 can flow out reliably. Unless the self-heating container 3 is inverted and stored in the upper open container 2, no hole is made in the film 10. There is no worry of leaking.
[0020]
And when not in use, the lower end of the self-heating container 3 is mounted in the lower recess 6b, so that the position of the self-heating container 3 that occurs when the water-heating type container 1 is transported, Is prevented. Even during use, the end of the self-heating container 3 is fixed in the lower recess 6b, so that good safety can be obtained.
[0021]
