A child-resistant closure that includes a base wall, a peripheral outer wall extending from the base wall, and an inner wall spaced radially inwardly from the outer wall and having an internal thread for securement to a container finish. The outer wall of the closure has diametrically opposed circumferential gaps, and the inner wall extends axially in radial alignment with the gaps in the outer wall for circumferential abutment with lugs on a shoulder of a container. The inner wall is flexible inwardly for clearing the container lugs and permitting removal of the closure from the container finish. The outer wall thus protects the force application area of the inner wall by reason of the fact that such force application area is recessed inwardly with respect to the circumference of the outer wall. The closure resists application of planer force to the removal area of the inner wall, such as by a child biting the closure. Furthermore, the modified dual-wall construction of the present invention may be constructed in small sizes suitable for use in conjunction with containers having small finish diameters.
