摘要： A closure includes an outer plastic shell (42) having a base wall (46), a peripheral skirt (48) with a central axis, a circumferential array of lugs (52) on an underside of the base wall, and a pair of axially spaced internal beads (60, 62) on the skirt spaced from the base wall. An inner plastic shell (44) has a base wall (68), a peripheral skirt (48) with a central axis, at least one internal thread on the skirt of the inner shell, a circumferential array of lugs (80) on an outer surface of the base wall, and a circumferential bead on an outer surface of the skirt remote from the base wall. The inner shell is positionable within the outer shell in a non-child-resistant first position with the bead on the skirt of the inner shell captured between the beads on the skirt of the outer shell, such that the outer shell is rotatably coupled to the inner shell and the at least one internal thread on the skirt of the inner shell can be threaded onto and off of a container by simple rotation of the outer shell. The inner shell is positionable within the outer shell in a child-resistant second position with the bead on the inner shell skirt spaced from the beads on the outer skirt, such that rotation of the outer shell is imparted to the inner shell by forced engagement of the lugs on the base wall.
