<p>A child resistant dispensing closure (10) having a cap (12) and a spout (14) mounted thereon for rotation about a substantially horizontal axis. The upper surface of the spout is provided with a plurality of ribs (48, 50), each of which has a distinct energy plane. Only one rib, usually, the rearmost (50), allows sufficient purchase to produce the force vector necessary to initiate rotation of the spout when a manual force is applied thereto. The cap includes a cylindrical skirt (18) with a frusto-conical section (16) extending upwardly therefrom. A protective flange (66) extends upwardly about the perimeter of the upper end of the frusto-conical section to deter unauthorized access to the spout. The upper wall of said cap is canted at an acuate angle to a horizontal plane passing through the cylindrical skirt of the cap, so that the spout is further recessed within the protective flange.</p> |
