DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a heating device. More specifically, it relates to a heating device which is convenient to carry about and capable of easily heating a cooked food in any place while never causing an accident, such as a burn, due to a high heat.
BACKGROUND ART
There has hitherto been known an exothermic body containing CaO as a main ingredient for heating a cooked food contained in a flat bag. This exothermic body utilizes heat generated by an exothermic reaction of CaO with water to heat the food.
However, the above-described exothermic body has entailed a danger of setting a flammable material on fire or burning a person due to damage of a recipient (enveloping body) containing the exothermic body because it rapidly generates a great amount of heat upon occurrence of the exothermic reaction.
For this reason, there has been earnestly desired a safe heat source free of such a disadvantage.
In view of the above-mentioned circumstance, it is an object of the present invention to provide a safe heat source which avoids rapid generation of a great amount of heat and is capable of easily heating a food or the like.
DISCLOSURE OF THE INVENTION
A heating device of the present invention is characterized by comprising:
(1) a first exothermic member disposed below a subject to be heated for preventing heat radiation from the subject while heating the subject from below, a second exothermic member disposed above the subject for preventing heat radiation from the subject while heating the subject from above, and a base for bearing the subject sandwiched between the first exothermic member and the second exothermic member while securing a space under the first exothermic member, whereby the subject is heated on both sides thereof; or
(2) a first exothermic member abutting one side of a subject to be heated for preventing heat radiation from the subject while heating the subject laterally, a second exothermic member abutting the other side of the subject for preventing heat radiation from the subject while heating the subject laterally, and a sandwiching and supporting body for accommodating the subject sandwiched between the first exothermic member and the second exothermic member, whereby the subject is heated on both sides thereof.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a heating device of the present invention will be explained with reference to the attached drawings.
In FIG. 1, numeral 1 denotes a first exothermic member, which is disposed below a subject 4 to be heated wherein a cooked food is contained in a flat bag, and plays a role of preventing heat radiation from the subject 4 while heating the subject 4 from below. Numeral 2 denotes a second exothermic member, which is disposed above the subject 4 and plays, like the first exothermic member 1, a role of preventing heat radiation from the subject 4 while heating the subject 4 from above.
Both of the first exothermic member 1 an
