Description
前記胴部は、厚さよりも幅が大きい扁平形状、且つ、当該扁平形状の厚さ方向に対称の形状となっており、
前記胴部の中心軸線に沿う軸線方向の一方側の端部は、前記口部に連なっており、
前記胴部における前記軸線方向の他方側の端部は閉塞するとともに、該軸線方向の他方側に膨出する湾曲形状となっており、
前記胴部における両側の幅方向端部にはそれぞれ、
前記押出ブロー成形の金型の分割面により形成されるパーティングラインが形成されており、
前記軸線方向に平行に延び、且つ前記パーティングラインに重複させて屈曲部が設けられており、
前記胴部を厚さ方向に押し潰して内容物を吐出する際に、前記屈曲部が、前記胴部の厚さ方向に対向する正面壁及び背面壁のうちの一方が他方に向けて反転変形する際の起点となるよう構成されていることを特徴とする。
前記屈曲部の頂点を基点とした前記正面壁に対する接線と、該頂点を基点とした前記背面壁に対する接線とのなす角度が140°以下であることが好ましい。
前記軸線方向の他方側の端部の輪郭線が、前記中心軸線上に位置する該他方側の端部の中心点を通り前記胴部の最大厚さを直径とする半円状の仮想円弧よりも内側に位置することが好ましい。
前記軸線方向の他方側の端部の輪郭線が、前記胴部の最大幅を直径とする略半円状となっていることが好ましい。
