Biaxially stretch-blow molded lightweight synthetic resin bottle container and method for production thereof |
摘要 |
A bottle-shaped container shows a large critical strength against buckling and is made of a reduced amount of synthetic resin material. A manufacturing method can manufacture such a bottle-shaped container. A lightweight bottle-shaped container made of synthetic resin and formed by biaxially-oriented blow-molding, characterized in that a wall thickness is increased to 109% or more of an average wall thickness of blow-molded pad of the wall at an infection point between a portion having a transversal cross sectional area and a portion having a different transversal cross sectional area in a cylindrical wall. The wall is thicker between the heel and the bottom, or at the waist, at the recessed rib, or at the projection.
