ABSTRACT:
A twist-to-open dispensing closure has a cap which threads directly onto the container neck. A bead at the bottom of the cap skirt snaps over a flange on the container neck for primary retention of the cap on the container neck. An upwardly projecting lug on the cap bead cooperates with a pair of axially extending walls on the container flange to give the user, while unthreading the cap, a sense of approaching the open, dispensing position of the closure and the cap locks in this dispensing position against further rotation, preventing accidental removal of the cap by snapping the cap bead over the container neck flange.
