DESCRIPTION:

BRIEF SUMMARY
BACKGROUND OF THE INVENTION

The present invention relates to an insole which is removably placed between the sole of a foot and the inside sole of a shoe. Heretofore, a variety of insoles have been proposed for curing athelete's foot and eliminating the unpleasant smell of a shoe. Most of them are incorporated with magnets, activated carbon, or copper sheet or wires. However, insoles of sch construction cannot produce the desired effect.


SUMMARY OF THE INVENTION

The present invention was completed based on the unique sheetlike battery disclosed in PCT/JP84/00100 filed by the present inventor, corresponding to U.S. patent application Ser. No. 675,060, filed Nov. 7, 1984 now U.S. Pat. No. 4,614,695. It is an object of this invention to provide an insole made of a sheetlike battery and which is superior in curing athlete's foot and other skin diseases and in eliminating the unpleasant smell of a shoe.
As disclosed in the specification of PCT/JP84/00100, the present inventor has developed a sheetlike battery composed of a positive electrode in the form of a sheet densely containing carbon fibers or fine carbon particles, a negative electrode of aluminum or zinc foil, and an electrolyte such as office paste interposed between the two electrodes. In experiments performed in searching for applications of such sheetlike battery, the present inventor has found that it effectively cures skin diseases or the like when the negative electrode side of the sheetlike battery is kept in contact with the skin of the human body. This finding led to the present invention.
The gist of this invention resides in an insole which is formed by cutting a sheetlike battery of the above-mentioned structure into the form of a sole of a foot. When in use, the insole is placed in a shoe such that the positive electrode contacts the inside sole of the shoe and that a sole of a foot is placed above the negative electrode. Preferably, the negative electrode of metal foil is covered with a moisture absorbent material.
The reasons why the above-mentioned insole cures skin diseases such as athlete's foot and eliminates the unpleasant smell of a shoe can be considered from various experiments of the present inventor, as follows: human body, some kinds of disease germs and bacteria are killed or the activities thereof are suppressed. That is, in the experiments of the present inventor, when the insole of the present invention was used in a shoe, which had been repeatedly worn for such a long period of time that sweat was absorbed inside the shoe and, as a result, gave off an unpleasant smell and was infected by bacteria, the unpleasant smell disappeared completely in a very short time.
In another experiment, it was found that when the present insole was used by those who were suffering from athlete's foot with itchy erythemas on the soles of their feet, itchness was removed almost immediately and did not appear again thereafter.
From the experiments set forth above, it could be assumed that the electric energy generated by the sheetlike battery constituting the insole flows from the positive electrode to the negative electrode through the moist inside sole and wall of the shoe, during which the electric energy kills bacteria on the inner wall of the shoe to eliminate the unpleasant smell and destroys germs causing athlete's foot. therein flow along with the movement of the electric energy and are absorbed into the body part to which the negative electrode of the battery abuts, so that skin diseases and the like at said body part are cured.
In the experiments conducted by the present inventor, it was observed that when the sheetlike battery is kept in contact with the affected part of the skin, a large amount of moisture (sweat) oozes out of the affected part. It is considered from this fact that the body fluids move along the flow of the electric energy and ooze out at the body part contacting the negative electrode of the sheetlike battery. As is well known, body fluids contain some ingredients which cure a wound and the like by themselves,
