<P>PROBLEM TO BE SOLVED: To provide a direct blow molded olefinic resin bottle which has an improved slipping down property at a bottom wall inner surface with respect to a non-oily viscous content such as ketchup. <P>SOLUTION: The olefinic resin bottle for the non-oily content is formed by direct blow and has multilayered structure including an innermost layer of an olefinic resin. In the bottle, a lower end of a bottle barrel wall functions as a periphery-shaped ground contact surface 30 including a ground contact part when the bottle is erectly held, a raised bottom section 31 which is higher than the periphery-shaped ground contact surface is formed at a position including a parting line X at a bottom wall 17 surrounded by the periphery-shaped ground contact surface 30. Further an inclined wall 33 formed between the periphery-shaped ground contact surface 30 and the raised bottom section 31 has an inclined inner surface with a maximum tilt angle of ≥30° of a tangent of the inclined wall toward a horizontal surface when seen at a vertical cross section including a bottom wall center O toward the periphery-shaped ground contact surface. When the bottom wall 17 is projected onto the level surface including the periphery-shaped ground contact surface 30, an area ratio of a projected surface of the raised bottom section 31 occupying the projected surface is 45% or less. <P>COPYRIGHT: (C)2012,JPO&INPIT |
