<p>PROBLEM TO BE SOLVED: To easily disassemble a plastic bottle at the time of throwing the same away and reduce its volume by forming a thin wall section formed into the narrow width provided all over from the top to the bottom. SOLUTION: A plastic bottle is provided with a bottom section 2, a side wall section 3 and a mouth section 1a of the diameter smaller than that of the side wall section 3, and one helical channel 4A as a thin wall section 4 formed into the narrow width all over from the top to the bottom on the side wall section 3 is formed on the outer surface of the side wall section 3. The side wall section 3 can be disassembled without the necessity of applying large force by cutting and tearing the side wall section 3 along the thin wall section 4. For instance, the side wall section is cut and opened along the thin wall section 4 formed all over from the top to the bottom to separate a strip section 7 of the side wall section 3, and a plastic bottle is disassembled into an almost flat bottom section 2, a pouring and discharging mouth section 1 with a mouth section 1a and the strip section 7. The crushing efficiency of a crusher is improved when, for instance, disassembled parts are crushed into chips for recycle and processed into PET.</p> |
