<p>PROBLEM TO BE SOLVED: To improve reinforcing effects of a body by forming peripheral recessed ribs in uneven patterns and by not forming the uneven patterns within the recessed ribs and in its vertical vicinity. SOLUTION: The plastic bottle 1 has a mouth 11, a shoulder 12, a body 13 and a bottom 14, wherein a recess 15 for attaching a handle is formed on a side of the body 13, and the handle 4 having a grasp 41 and an attaching arm 42 is attached to the recess 15. Innumerable fine uneven patterns 2 comprising independent protrusions 21 surrounded by recesses 22 are formed approximately around an entire peripheral face of the bottle 1. In this case, recessed ribs 3 for reinforcing the body 13 are formed at upper and lower appropriate sites. The uneven patterns 2 are not formed within the recessed ribs 3 and in their vertical vicinity 31, while a longitudinal cross-sectional shape of the rib 3 is made constant, thereby improving reinforcing effects and preventing the body from deforming or the like.</p> |
