<p><P>PROBLEM TO BE SOLVED: To increase the deformation resistance of a panel portion. <P>SOLUTION: In this bottle 10, a mouth portion 11, a shoulder portion 12, a body portion 13 and a bottom portion 14 are integrally formed from a synthetic resin; and the plurality of panel portions 17, which are depressed inward in the radial direction of the body portion 13, are provided at intervals around the central axis line O of the bottle 10 in the body portion 13. The panel portion 17 keeps a mountain portion 18 and a valley portion 19 alternately and continuously provided around the central axis line O. The valley portion 19 is composed of a plurality of inclined planes 20 which are linearly inclined so that the amount of radially inward depression can become gradually larger toward central portions 19a and 19b of the valley portion 19 from its outer peripheral edge. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
