Paperboard storage container with child resistant sliding drawer

Abstract

A child resistant paperboard storage container assembly including a sleeve with an open end. A drawer is slidably disposed within the sleeve and accessible from the open end and configured to slide into and out of the open end of the sleeve. A locking system restricts withdrawal of the drawer from the sleeve and includes a locking leg formed from a cut out portion of the bottom of the drawer that projects toward the open end of the sleeve. A locking flap is located on an inside surface of the bottom of the sleeve and projects upward. The locking leg engages with the locking flap when the drawer is slid from the interior of the sleeve so as to prevent the drawer from being slid out of the sleeve. An unlocking tab is displaceable into the sleeve to lift the locking leg over the locking flap.
