Problem: it is possible to manufacture inexpensive and inexpensive, and especially in the case of froth, it is possible to improve the tightening of the froth when the thick paper is folded and formed in the bow shape, and the bow shape is not deformed.Solution: since the froth f is sandwiched between the two thick sheets of the holes H2 to which the froth f is stretched, and is bonded to the froth f in a center shape, and is formed into an arcuate shape, and is used as a simple interdental cleaning tool, it is thin and not bulky It is small and suitable for carrying. Moreover, since the paper is not deformed by the paper, the sliding operation by the floss f is not impaired.Further, since the outer end of the froth is baked and melted, and the outer end of the froth f is formed in a spherical shape, the spherical portion B becomes a stopper, and even if an excessive force is applied, the spherical portion B is not removed.Diagram【課題】嵩張らず安価に製造でき、特にフロスを中心に厚紙を折り重ねて弓状に形成する際にフロスの締まりが向上し、弓状が変形しない構成とする。【解決手段】フロスfを張る穴h2の開いた2枚の厚紙の間にフロス用の糸を挟んだ状態で接着して、前記フロスfを中心に二つ折りして重ね、弓状に形成し使用する構造の簡易歯間清掃具であるので、薄板状で嵩張らず、小型で携帯に適している。しかも紙製で変形しないので、フロスfによる摺動操作が損なわれることはない。また、前記フロス外端を焼き切って溶融させ、フロスfの外端を球状に形成してあるので、この球状部Bがストッパーとなり、無理な力が加わっても抜けることはない。【選択図】図1
