Abstract
A synthetic resin container closure does not render required initial torque and required secondary torque for unsealing excessively high, and but can fully reliably prevent slipping-out, a phenomenon where a locking device ascends while elastically climbing over a locking jaw portion, without causing breakage of a circumferential breakable line, at the time of unsealing. Such a synthetic resin container closure and a combination of the synthetic resin container closure and a container are provided. An inverted truncated cone-shaped fitting surface extending upwards at a radially outward incline from the base edge of an upper surface of the locking device is disposed in the inner peripheral surface of a tamper evident bottom section demarcated below the circumferential breakable line formed in a skirt wall.
