<p>PROBLEM TO BE SOLVED: To provide a plastic bottle that slides down while kept in a horizontal position on a slope plate for filling bottles into or taking it out from a vending machine, so that jamming of bottles on the slope plate can be eliminated. SOLUTION: A bottle body 100 is constituted as follows. A level difference 121 is formed outward on the upper end of a cylindrical trunk 130, from where a shoulder 120 is consecutively formed; a level difference 141 is formed outward on the lower end of the trunk 130, from where a bottom 140 is consecutively formed; and a neck-to-mouth 110 is consecutively formed on the upper end of the shoulder. A cap 200 is attached on the neck-to-mouth 110, thus the plastic bottle 10 comprising the bottle body 100 and the cap 200 is formed. On the upper part of the level difference on the lower end at the shoulder, a plurality of concavities 122 are formed in the circumferential direction. On the lower part of the level difference on the upper end at the bottom, a plurality of concavities 142 are formed in the circumferential direction.</p> |
