Abstract
The present invention is a child resistant cap and dispenser. It includes a dispensing container, a flange located non-rotatably connected on the container neck with one-way ratchets, located thereon, said flange being non-rotatably connected to said container neck; a ring collar, non-removably and rotatably connected to the container neck with one-way ratchets located thereon, in functional and cooperative contact with the flange ratchets to permit rotation of it about the neck in one direction and so as to prevent rotation in the opposite direction. The ring collar has an outer circular wall, with one of (i) at least one keyway track and, (ii) at least one keyway protrusion, located thereon, the other being located on a cap, adapted to fit onto the said ring collar. There is a spring mechanism located on at least one of the necks, the collar and the cap, to bias the cap upwardly away from the dispensing container when the cap is connected to the ring collar.
