Child resistant crowned closure having improved opening feature

Abstract

A child resistant package comprising a container having a neck finish including an annular locking ring with at least one notch having a locking rib therein and indicium indicating the location of the notch, and a snap-on closure of rigid and stiff material disposed for rotary movement on the neck finish, said closure comprising an end wall, a resilient peripheral skirt, and a crown extending upwardly and outwardly from the end wall and the skirt to form a surface that provides leverage for removal of the closure from the container with a locking lug extending radially inwardly from said skirt in alignment in a fire position with said notch upon rotation of the closure to permit removal of said closure only when in the fire position, and snap beads co-planar with the locking luck and extending inwardly from the skirt, said snap beads being longer than the notch is wide, a finger tab comprising indicium and extending radially outwardly from said skirt in alignment with said locking lug, said snap beads camming over said locking ring and resiliently expanding said skirt and the locking lug passing over the locking ring upon snap locking the closure to the neck finish and upon removal of said closure, said locking lug and said snap beads being interengaged with said locking ring upon snap locking and said snap beads becoming disengaged from said locking ring upon the removal of said closure.
