The relative displacement between the sub-lid 12 and the main lid 11 is achieved by the movement of the stopper ring protrusion 113 in the width direction of the ring groove 114. Meanwhile, it should be noted that the width direction of the ring groove 114 is the axial direction of the cap assembly 1.
Meanwhile, the extending direction of the retainer ring protrusion 113 here is the extending direction along the circumferential direction (i.e. the circumferential direction of the cap assembly 1, where the circumferential direction and the axial direction are not described, i.e. the circumferential direction or the axial direction of the cap assembly 1), and is the same as the extending direction of the first arc block 111 or the second arc block 112 (it should be noted that the extending direction of the first arc block 111 and the second arc block 112 here refers to the extending direction along the circumferential direction).
