Abstract:
A child resistant cap and dispenser, which comprises:(a) a dispensing container having a main body with walls and a bottom, and having a top with a neck and a dispensing orifice;(b) a flange located about said container neck and having one-way ratchets with stops in one direction of rotation and ramps in an opposite direction, located thereon; said flange being non-rotatably connected to said container neck;(c) a ring collar, non-removably and rotatably connected to said container neck and having one-way ratchets located thereon and in functional and cooperative contact with said flange ratchets so as to permit rotation of said ring collar about said container neck in one direction and so as to prevent rotation thereof about said container neck in an opposite direction, said ring collar having an outer circular wall, said wall having one of (i) at least one keyway track and, (ii) at least one keyway protrusion, located thereon, said keyway track having a non-linear path to create a locking position for said keyway protrusion requiring complex motion for unlocking;(d) a cap adapted to fit onto said ring collar, said cap having the other of one of said (i) at least one keyway track and (ii) at least one keyway protrusion, located on an inside wall thereof;(e) spring biasing means located on at least one of said neck, said collar and said cap, and located to bias said cap upwardly away from said dispensing container when said cap is connected to said ring collar;wherein when said cap is placed onto said ring collar and rotated thereon in a downwardly rotating fashion, and said keyway track and said keyway protrusion engage to a locking position, said cap and ring collar may not be rotated in one direction due to ratchet stop interaction and said cap and ring collar may be rotated in an opposite direction while said keyway track and said keyway protrusion remain engaged in said locking position; and,wherein when said ring collar is held stationary and said cap is pressed downward and rotated in an unlocking keyway position, said cap may be removed from said ring collar.
