Abstract
It is intended to provide a synthetic resin bottle, in which the stable no-leak condition can be maintained up to a certain cap-turning angle, and air-tightness of the bottle can be fully secured, even if the cap is falsely turned. The body 2 of the synthetic resin bottle is configured to have a smooth seal surface 8 with no irregularity over the entire circumference in the upper portion of the outer neck wall where no parting line is formed. In this configuration, a stable no-leak condition can be maintained up to a certain cap-turning angle, and air-tightness of the bottle can be fully secured, even if the cap is falsely turned.
