A container and child-resistant closure assembly includes a cap formed from a single piece, a cup shaped inner member having a top wall, an outer wall, and a depending sidewall. The sidewall includes a threaded interior surface. The outside wall of the inner member includes connection members for securing to an outer member. The outer member has a ring-shape with a plurality of inwardly facing lugs. Each of the plurality of inwardly facing lugs is cylindrically-shaped and protrudes radially inwardly from the outer member. The container assembly also includes a container including a neck forming an opening. The neck has a threaded exterior surface and a plurality of ramps. Each of the plurality of ramps faces radially outwardly from the neck and has a gently sloping face and a steeply sloping face.
