<P>PROBLEM TO BE SOLVED: To improve the decompression absorbing function by a decompression absorbing panel in a synthetic resin-made round bottle without increasing the area of the decompression absorbing panel. <P>SOLUTION: In a round bottle, a plurality of decompression absorbing panels are circumferentially recessed in a parallel manner over the range of a predetermined height of a cylindrical barrel part, and column parts remain in the longitudinal direction between the adjacent decompression absorbing panels. A stepped part of an inclination smaller than that of an inclined surface is arranged in a chamfering shape at boundary parts between an arc-like column part and the inclined surface forming right and left ends of the decompression absorbing panel in a recessed manner in a plane cross part view, while the boundary parts forming the right and left edges of the decompression absorbing panel. <P>COPYRIGHT: (C)2012,JPO&INPIT |
