ABSTRACT:
A child-resistant package that includes a wide mouth blown glass container or blow molded plastic container, and a molded thermoplastic closure that is affixed to the finish portion of such container. The finish portion of the container has a radially outwardly projecting flange at the bottom portion of such finish portion, and this flange has a notch in its outer periphery. The closure has a flexible projection that extends outwardly and downwardly from the skirt of the closure, and a portion of this projection engages the notch in the flange of the finish to prevent the turning of the closure on the finish. The projection of the closure can be manipulated by hand to remove the portion of the projection that engages the notch in the container finish to disengage the closure projection from the container finish notch, to permit the removal of the closure from the container. In one embodiment, the closure is normally retained on the container finish by means of a snap-on bead that projects inwardly from the closure skirt and engages a locking bead that projects outwardly from the container finish. In an alternative embodiment, the container finish is provided with an outwardly projecting helical thread, and the closure is provided with an inwardly projecting helical thread that engages the helical thread of the container finish.
