この種の歯間ブラシとしては、毛、毛を撚り合わせたワイヤーおよびワイヤーに取付られた柄よりなり、ワイヤーの基部に抜止用屈曲部が形成されており、柄に対するワイヤーの取付が、これらのインサート樹脂成形によって果たされているものが知られている（例えば、特許文献１参照。）。
【０００３】
【特許文献１】
実開昭６２−１７４４２３号公報
【０００４】
【発明が解決すべき課題】
インサート樹脂成形は、成型用金型の構造が複雑で、高価につき、設備費が高い。また、金型にワイヤーをセットする作業は時間と手間が掛かり面倒である。したがって、インサート樹脂成形によって製造された歯間ブラシは高価である。
【０００５】
この発明の目的は、安価な歯間ブラシおよびこれを製造することのできる製造方法を提供することにある。
【０００６】
【課題を解決するための手段】
この発明による歯間ブラシは、毛、毛を撚り合わせたワイヤーおよびワイヤーに取付られた柄よりなり、柄が、メインボディおよびサブボディよりなり、メインボディに、ワイヤーの基部を挿入した縦孔および縦孔と交差させられた横孔が形成されており、ワイヤーの基部に、抜止用屈曲部が横孔に臨ませられるように形成されており、サブボディに、屈曲部の周囲を取囲んで横孔内に充満させられた係止部が設けられているものである。
【０００７】
この発明による歯間ブラシでは、インサート樹脂成形を用いることなく、単なる樹脂成形によって製造することが可能である。したがって、安価な歯間ブラシが提供される。
【０００８】
さらに、メインボディの表面の一部にサブボディが被覆させられており、メインボディおよびサブボディの識別性が互いに相違させられていると、視覚的な訴求力を付加することができる。
【０００９】
また、メインボディおよびサブボディが、合成樹脂製であると、樹脂同士の嵌合性が高く、メインボディおよびサブボディの結合力を強化することができる。
【００１０】
また、識別性の相違が、色、光沢および材質の少なくともいずれか１つに基因させられていると、識別性の相違を簡単に変更することができる。
【００１１】
さらに、メインボディが、肩部、尻部およびこれらを低い段を介して連絡している胴部よりなり、横孔が、胴部に位置されられており、サブボディが、胴部に被覆させられており、肩部および尻部表面と、これらに隣接させられたサブボディ表面との境界が面一となされていると、柄全体に平滑な印象を与えることができ、商品性の向上に貢献できる。
【００１２】
この発明のよる歯間ブラシの製造方法は、縦孔および縦孔と交差させられた横孔を有する、柄のメインボディを一次樹脂成形し、毛を撚り合わせたワイヤーの基部を、横孔に臨ませられるように縦孔に挿入し、横孔を通じて、ワイヤーの基部に抜止用屈曲部を形成し、柄のサブボディを、その一部が屈曲部の周囲を取囲んで横孔内に充満させられるように二次樹脂成形するものである。
【００１３】
この発明のよる歯間ブラシの製造方法では、毛、ワイヤーおよび柄を、それぞれに別々の工程で製造することができ、シンプルな工程でもって歯間ブラシを製造することができる。したがって、歯間ブラシの製造費が安価で済む。
【００１４】
さらに、屈曲部の形成を、横孔に棒状ジグを挿入し、ジグの先端部をワイヤーの基部の屈曲部形成予定部に押当てることによって行うと、屈曲部を形成するためのジグの一部の役割をメインボディが果たすし、屈曲部の形成そのものも簡単である。
【００１５】
また、一次樹脂成形および二次樹脂成形に際し、同一の材料を用いると、材料費の節約にもなるし、製造工程の管理を容易に行うことができる。ただし、一次樹脂成形および二次樹脂成形に際し、異なる材料を用いてもよい。
【００１６】
