PROBLEM TO BE SOLVED: To give a clear feeling when a lid is closed by enhancing an impact right before an inward protruding part of the lid climbs over an outward protruding part of a container body structuring the locking part of the lid and by shortening the distance for climbing over.SOLUTION: An outer peripheral face of a container body neck part is formed with a male screw part and an inner peripheral face of a lid peripheral wall is formed with a female screw part. The outer peripheral face of the container body is formed protruding with outward protruding parts along its outer peripheral direction with spacings and each outward protruding part is extended diagonally and is formed tilted in an opposite direction from the tilting direction of the male screw part. The inner peripheral face of the lid is formed protruding with inward protruding parts corresponding to each of the outward protruding parts with spacings along its inner peripheral direction. At least either the container body or the lid has elasticity for the inward protruding parts to climb over the outward protruding parts in opening and closing the lid. The container has more than one set of lid locking part comprising the outward protruding part and the inward protruding part. |
