<p><P>PROBLEM TO BE SOLVED: To design a bottle shape improving the lateral rigidity and strength of a bottle without increasing a material cost caused by a heavy wall thickness as a technical purpose, and inexpensively provide a synthetic-resin-made bottle which can be smoothly used in a vending machine or the like, is free from deformation when stacked for storage, and exhibits a sufficient reduced pressure absorption function for use in high-temperature filling. <P>SOLUTION: The synthetic-resin-made bottle 1 has a plurality of protruding pillars 15 on a barrel while being inclined at a constant tilt angle from the center axis of the bottle and spirally parallel to one another, thereby suppressing deformation caused by a pressing force working to the tubular wall of the barrel from a horizontal direction. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
