child resistant closure with schutzrand and inclined upper wall

摘要

A child resistant dispensing closure having a cap and a spout mounted thereon for rotation about a substantially horizontal axis. The upper surface of the spout is provided with a plurality of ribs, each of which has a distinct energy plane. Only one rib, usually, the rearmost, 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 with a frusto-conical section extending upwardly therefrom. A protective flange 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 acute angle to a horizontal plane passing through the cylindrical skirt of the cap, so that the spout is further recessed within the protective flange.
