PROBLEM TO BE SOLVED: To consider a method for solving problems in which it is impossible to make fine adjustment of the straining of a floss thread for interdental cleaning because an arched product becoming a main stream in Japan is a disposable product in retrograde to the times, and also in a method being widely used in each European country and in the United States for many years, the method that winds a thread several times in the vicinity of the first joints of middle fingers of both hands, and pinches it with an index finger and a thumb, many steps to usage are present and complex, and skill becomes indispensable, in addition, the Japanese have habitual resistance against putting fingers in the oral cavity and have problems in the oral shape, and therefore the spread proceeds only slowly.SOLUTION: A floss thread supply device is invented by the present inventor, the device being simple in operation procedures of a floss thread for interdental cleaning and facilitates replacement, can finely adjust the straining of the floss thread for interdental cleaning being an important factor when in use, and can fix the end completely. This floss thread supply device is attached to an exclusive interdental cleaning tool of each shape, and whereby the fine adjustment of replacement, fixation and straining of the floss thread for interdental cleaning is simplified easily.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】日本国内において主流となる弓形状製品においては、時代に逆行して使い捨て製品であり、歯間清掃用フロス糸の緊張を微調整することが不可能である。永年に亘り広くヨーロッパ各国及びアメリカ合衆国で愛用される両手中指第一関節付近に数回巻き付け、人差し指と親指で摘まんで使用する方法においては、使用までの工程数が多く複雑なうえ、熟練性が不可決となる。加えて、日本人においては口腔内に指を入れることに対しては習慣的抵抗があり、口の形状においても問題であり普及は遅々として進まない。これらの課題を解決する方法を考察した。【解決手段】本発明者は、歯間清掃用フロス糸の使用手順が簡易且つ取り換えが容易であり使用時に重要な要素である歯間清掃用フロス糸の緊張を微調整でき、端部を完全固定できるフロス糸供給装置を発明した。このフロス糸供給装置を各形状の専用歯間清掃具に装着することで、容易に歯間清掃用フロス糸の取り換え、固定、緊張の微調整が簡易となった。【選択図】図1
