<p><P>PROBLEM TO BE SOLVED: To suppress the deformation that a panel part is not restorable when the internal pressure in a bottle is largely fluctuated. <P>SOLUTION: In a bottle 10, a mouth part 11, a shoulder part 12, a barrel part 13 and a bottom part 14 are integrated with each other with a synthetic resin, and six panel parts 17, 18 recessed inwardly in their radial direction are equally spaced in the barrel part 13 in the circumferential direction of the barrel part 13. The six panel parts 17, 18 have three of first panel parts 17 and three second panel parts 18 having the deformation resistance in the radial direction larger than the first panel parts 17, respectively, and the first panel pars 17 and the second panel parts 18 are alternately arranged along the circumference. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
