<p><P>PROBLEM TO BE SOLVED: To provide a plastic bottle container which can suppress nonuniform deformation while assuring reduced pressure absorption performance, and has a shape capable of stably molding without causing a trouble in mold-die opening after molding when reducing the capacity of a plastic bottle container. <P>SOLUTION: A reduced pressure absorption panel 6 is formed between a plurality of pillar parts 8 disposed on the same circumference, and the pillar parts 8 and the reduced pressure absorption panel 6 are opposed in the radial direction. The reduced pressure absorption panel 6 is positioned in the range surrounded by a circular arc R3 which is convex outward the container of curvature radius ofϕmutually contacting a circular arc R1 of curvature radius ofϕ×3/4 which is convex outward the container passing through both the ends of the reduced pressure absorption panel 6 at the middle point on the horizontal section whereinϕis the maximum outside diameter of the container 1, a circular arc R4 which is convex inward the container of curvature radiusϕ×3/2 mutually contacting a circular arc R2 of curvature radiusϕwhich is convex inward the container passing through the both ends of the reduced pressure absorption panel 6 at the middle point, and straight lines L1, L2 connecting the center of the container and both the ends of the reduced pressure absorption panel 6. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
