A package having child-resistant and non-child-resistant modes of operation includes a plastic container having a cylindrical finish and at least one external thread on the finish spaced from the open end of the finish. An external circumferentially extending first engagement element is provided on the finish between the external thread and the open end of the finish, and has an outside diameter that is less than that of the external thread. A manually deflectable release element is externally cantilevered from the finish on a side of the thread remote from the open end. A plastic closure has a base wall and a peripheral skirt with at least one internal thread for engagement with the at least one external thread on the finish in a child-resistant mode of operation. There is at least one locking lug on the skirt for releasable engagement with the release element on the container in the child-resistant mode of operation. An annular wall extends from the base wall in a direction opposite from the skirt. A second engagement element is disposed on the inner surface of the annular wall for engagement with the first engagement element on the container finish in an inverted non-child- resistant mode of operation of the closure. In disclosed embodiments of the invention, the engagement elements may comprise circumferential beads or circumferential threads on the container finish and the annular wall of the closure.
