<p><P>PROBLEM TO BE SOLVED: To increase the decompression absorption capability of the entire bottle container by forming circumferential ribs with weak parts, thereby securely preventing the occurrence of permanent deformation when decompression is caused, and reasonably enhancing the decompression absorption capability of the entire bottle container. <P>SOLUTION: Circumferential ribs 5 are formed around the barrel 1 composed of pillar walls 4 forming corners and flat walls 2 into a polygonal tube. The weak parts 6 the groove depths of which are shallow are formed on the flat walls 2 of the circumferential ribs 5. Opposite reinforcement ribs 7 are formed on the flat walls 2 near the weak parts 6 almost over the entire widths of the weak parts 6. Decompression absorption panels 3 are formed on the desired flat walls 2 so as to avoid the circumferential ribs 5. Flexibility is enhanced by the weak parts 6 in order to prevent permanent deformation. Absorption capacity is increased. The degree of flexibility by the weak parts 6 is restricted by the reinforcement ribs 7 and thereby the degree of decompression absorption is enhanced. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
