PROBLEM TO BE SOLVED: To provide a small bottle having a small internal capacity with a heat resisting characteristic without impairing a transport characteristic.SOLUTION: A bottle 1 whose internal capacity is at least 50 ml. but no larger than 150 ml. is formed by blow-molding a preform formed by mold injection and has a tubular mouth 12 at the bottom end of which the neck ring 11 is formed and a tubular body 13 with a bottom jointly formed at the bottom end of the mouth 12. An outer diameter (A) of the body 13 is at least 1.0 but no more larger 1.5 times larger than the outer diameter B of the neck ring 11, the degree of the crystallization of the body 13 is at least 25% but no higher than 35% and the weight of the body 13 is at least 1.0 but no heavier than 1.3 times heavier than the weight of the mouth 12. A reinforcement peripheral groove 14 is formed on the body 13. |
