ABSTRACT:
A hand-held cap opener fitting the palm of the hand is employed in removing a cap from the child resistant container. The container terminates in a cylindrical neck having threads thereon and a first indicia at a circumferential position providing unlocking of the cap with the cap rotated to a corresponding angular position. The cap includes a radially outward second indicia projection. With the cap radial projection and the first indicia in circumferential alignment, the cap may be pried off the threaded end of the container neck. The cap opener is preferably of molded plastic and unitary form including a palm-held flat plate having top and bottom surfaces. A ring integral with the plate projects from the bottom surface with the ring sized slightly larger than the diameter of the cap which is received therein. An opening in the ring at the longitudinal center line of the flat plate receives the second indicia projection on the cap. Rotation of the cap opener flat plate causes the cap projection to contact the side of the opening in the ring to thereby facilitate rotation of the cap to align the indicia projection on the cap with the indicia on the container neck. Depression on the plate to the rear of the ring, diametrically opposite the opening in the ring receiving the cap projection permits the plate to act as a lever to snap the cap from the container neck. A hole in the plate aligned with the hole in the ring permits viewing of the projection on the ring as captured within the ring hole. The edge of the ring remote from the plate may be beveled downwardly in a direction away from the hole in the ring receiving the cap projection to facilitate entry of the cap within the ring and engagement with the cap opener.
