BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thermal bag that expands by generating carbon dioxide simultaneously with a thermal action.

[0002]

2. Description of the Related Art There are many known products for warming each part of the body and improving fatigue and swelling.
Heated ships are commercially available. However, they merely provide heat and do not provide sufficient effects on fatigue and swelling. In addition, chemical warmers and the like utilizing the heat of oxidation of metal powders are also known, but these are also merely warmed and have insufficient effects on fatigue and swelling.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a thermal bag excellent in improving fatigue and swelling.

[0004]

Means for Solving the Problems The present inventors have inflated the bag by generating carbon dioxide gas due to the reaction between carbonate and acid at the same time as the heat generated by the exothermic reaction between the exothermic agent and water, thereby compressing a part of the body. By doing so, it has been found that a high blood flow improvement effect can be obtained by the surplus effect of the heating action and the compression release, and fatigue and swelling can be greatly improved.

That is, the present invention provides (A) a heating agent which generates heat by reacting with water, (B) water and / or a hydrate salt, (C) an acid and (D) a carbonate in a sealed bag. The components are sealed so that they do not react, and components (A) to
It is intended to provide a thermal bag which expands by mixing (D) in the bag.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The exothermic agent of the component (A) used in the present invention is not particularly limited as long as it exhibits an exothermic reaction when reacted with water.

[0012] In the case of a double bag structure, the inner bag has a relatively lower strength than the film constituting the outer bag, and is not easily broken in a normal storage state.
It is necessary to have enough strength to break the bag when the necessary strength is added during use. Further, the sealing portion of the inner bag may have such strength. For example, the inner bag is filled with the component (B), and the outer bag is sealed with the components (A), (C) and (D). The inner bag is filled with the components (B) and (C) or (D). A heating bag having a double bag structure can be obtained by a method of filling, sealing the components (A) and (C) or (D) in an outer bag, and sealing.

In the case of separating two or more chambers, a film or the like constituting a partition wall is relatively weak in strength as compared with the other parts of the film or the like. Strength is required. To isolate into two compartments, one compartment contains component (B) and the other compartment contains components (A), (C) and (D).
