Description
燃料タンクは、タンク外壁から一体的に燃料タンクの外方向に延出されたパイプ取付部を有し、
パイプ取付部は、タンク外壁から外方向に一体的に連続して円筒状に延出されタンク外壁と同一材料で形成される取付部外側壁と、取付部外側壁の先端から連続してヘヤピン状に屈曲して取付部外側壁の内側に形成される取付部内側壁を有し、取付部外側壁と取付部内側壁が密着して形成されている燃料タンクのパイプ取付構造である。
本発明の実施の形態において、ブロー成形装置で製造される燃料タンク1は、図1に示すように、その燃料タンク1に燃料ポンプ(図示せず)等を出し入れするためにポンプユニット取付孔4が上面に形成されている。また、燃料タンク1の側面又は上面には、フィラーパイプ(図示せず)から燃料を注入するパイプ取付部20が形成されている。
さらに、燃料タンク1の上面には、内部の燃料蒸気を回収するホース等を接続する各種のパイプ取付部20が形成されている。
図3及び図4に示すように、パイプ取付部20は、燃料タンク1のタンク外壁10から外方向に一体的に連続して円筒状に延出して形成されている。
取付部外側壁21は、少なくとも内部に取付部外側壁バリヤ層21aを有しており、同様に、取付部内側壁22は、少なくとも内部に取付部内側壁バリヤ層22aを有している。
また、同様に、取付部内側壁22は、取付部内側壁バリヤ層22aの外側(パイプ取付部20の内面側)は、取付部内側壁外側層22bを形成し、取付部内側壁バリヤ層22aの内側(取付部内側壁22と対向する側)は、取付部内側壁内側層22cを形成する。
取付部外側壁スプール21dは、図4に示すように、取付部外側壁21の先端付近に外周部に外径方向に突出して形成されている。
取付部外側壁スプール21dを設けたため、パイプ取付部20にフィラーパイプ等のパイプ部材を取付けたときに、そのパイプ部材が外れにくくすることができる。
図5に示すように、まず、ブロー成形金型30のキャビティー面33からブロー成形金型30の内部方向に円筒状に凹んだ取付部成形部31を設ける。取付部成形部31の内径は、パイプ取付部20の外形と同じである。
