Description

OI 13339 ABSTRACT OF THE DISCLOSURE A child-resistant container and closure combination includes a one piece molded closure threadable on a container neck. When the closure is fully threaded onto the container neck, a pawl, integrally formed on the bottom of the closure skirt, interlocks with a lug projecting from the container neck to prevent rota- tional removal of the closure. One end of the pawl is integrally attached to the closure by a relatively thin and flexible bridge, and a slot is formed in the closure skirt immediately above the pawl and bridge. The flexibility provided by the slot and the thin bridge attachment permits the pawl to be manually deflected upwardly to disengage the pawl and lug, thereby permitting rota- tional removal of the closure.
