A child resistant cap includes: (a) a main closure base; (b) an outer ring unit that functions as a safety collar; (c) a dispensing mechanism on the base; (d) an overcap. The base attaches to a top dispensing container and the horizontally rotatable ring unit is attached to the base. Alternatively, the outer ring unit is fixedly attached to the container. The overcap has protrusions and the ring has at least one corresponding cut out. There is a ring cut out gap lock and lever that prevents at least one protrusion from passing through a cut out gap, unless it is moved to a release position after alignment of the ring unit and overcap and the lever is pushed upwardly to release the lock and lift the overcap.

1. A child resistant cap with safety ring, ring gap lock and lever for direct attachment to a rim of container, which comprises: a) an outer ring unit having a circular wall with a horizontal track thereon for attachment to the rim of a container having a top dispenser and having a rim of greater diameter than its adjacent neck, so as to connect said outer ring unit to said rim so as to be horizontally and vertically fixed thereon, said outer ring unit having a top with an outwardly biased ledge and a recess below said ledge to permit an overcap to be inserted onto and removed from said outer ring unit, and said ledge having at least one cut out gap thereon;b) at least one moveable ring gap lock and gap lock lever located in said at least one cut out gap, said ring gap lock having a moveable member with a first position, being a locked position blocking said at least one cut out gap, and said moveable member having a second position, being a release position opening said at least one cut out gap, and said lever being connected to said lock and being positioned so as to be pushed upwardly to press upon a bottom of said overcap to force said overcap upwardly when said overcap is positioned in a gap position, being an unlock and open position;c) and, one of said outer ring unit, said at least one moveable ring gap lock and said lever having a first alignment indicia thereon;d) an overcap having a circular bottom adapted to be inserted over said top dispenser of said container and onto said outer ring unit and vertically locked onto said recess of said outer ring unit, said circular bottom having a second alignment indicia, and said overcap having at least two protrusions thereon, at least one of which has a geometry of adequate size to freely move through said at least one cut out gap when said gap lock is in its release position, and of adequate size and geometry to prevent removal of said overcap from said outer ring when said gap lock is in said locked position;e) further wherein said outer ring unit ledge has an underside and said at least two protrusions of said overcap have a top, wherein the underside of said ledge prevents the top of said at least two protrusions from passing over said ledge, except when in the gap position when said lock is moved to said release position to permit at least one of said at least two protrusions to pass therethrough; and, wherein when one of said outer ring unit and said overcap is held, and the other of said outer ring unit and said overcap is rotated to place said first alignment indicia and said second alignment indicia in alignment with one another, and then said gap lock is moved into said release position by said moveable lever being pushed inward and upward to release the lock and to act as a lever to push said overcap upward, said overcap is thereby removed from said outer ring unit to uncover said top dispenser of said container for use. 2. The child resistant cap with safety ring, ring gap lock and lever of claim 1 wherein said at least one cut out gap is a plurality of cut out gaps. 3. The child resistant cap with safety ring, ring gap lock and lever of claim 1 which further includes a container attachment means selected from the group consisting of threading, snap-lock and spring lock. 4. The child resistant cap with safety ring, ring gap lock and lever of claim 1 further having at least two speed bumps located below said outwardly biased ledge adapted to reduce for horizontal movement of an overcap until minor frictional engagement is surpassed by minimal force. 5. The child resistant cap with safety ring, ring gap lock and lever of claim 1 wherein said ring gap lock is selected from the group consisting of a slide lock, a hinge lock and a swing lock. 6. The child resistant cap with safety ring, ring gap lock and lever of claim 1 wherein said ring gap lock is a hinged ring gap lock that may be pressed to move it from said locked position to said release position by upward movement of said lever. 7. The child resistant cap with safety ring, ring gap lock and lever of claim 1 wherein there are at least three protrusions, said protrusions being spaced apart from one another. 8. The child resistant cap with safety ring, ring gap lock and lever of claim 1 wherein said underside of said ledge and said top of said at least one protrusion have non-smooth topographies to enhance said frictional contact. 9. The child resistant cap with safety ring, ring gap lock and lever of claim 1 wherein at least one of said ledge and said at least two protrusions are flexible so as to permit insertion of said overcap onto said outer ring without alignment of said at least two protrusions and said at last two cut out gaps, and are upwardly inflexible so as to prevent removal of said overcap from said outer ring, except when there is alignment and said gap lock is in its release position. 10. The child resistant cap with safety ring, ring gap lock and lever of claim 1 wherein there are two ring gap locks at two different gaps. 11. The child resistant cap with safety ring, ring gap lock and lever for direct attachment to a container having a rim of greater diameter than its neck, which comprises: a) an outer ring unit having a circular inside wall with a horizontal track thereon for attachment to the rim of a container having a top dispenser and having a rim of greater diameter than its adjacent neck, so as to connect said outer ring unit to said rim so as to be horizontally and freely rotatable thereabout, said outer ring unit having a top with an outwardly biased ledge and a recess below said ledge to permit an overcap to be inserted onto and removed from said outer ring unit, and said ledge having at least one cut out gap thereon;b) at least one moveable ring gap lock and gap lock lever located in said at least one cut out gap, said ring gap lock having a first position, being a locked position blocking said at least one cut out gap, and having a second position, being a release position opening said at least one cut out gap, and said lever being connected to said lock and being positioned so as to be pushed upwardly to press upon a bottom of said overcap to force said overcap upwardly when said overcap is positioned in a gap position, being an unlock and open position;c) one of said outer ring unit, said at least one moveable ring gap lock and said lever having a first alignment indicia thereon;d) an overcap having a circular bottom adapted to be inserted over said top dispenser of said container and onto said outer ring unit, said circular bottom having a second alignment indicia, and said overcap having at least two protrusions thereon, at least one of which has a geometry of adequate size to freely move through said at least one cut out gap when said gap lock is in its release position, and of adequate size and geometry to prevent removal of said overcap from said outer ring when said gap lock is in said locked position;e) further wherein said outer ring unit ledge has an underside and said at least two protrusions of said overcap has a top, wherein the underside of said ledge and the top of said at least two protrusions are in frictional contact with one another when said overcap is inserted into said outer ring unit such that when one of said outer ring unit and said overcap are rotated, the other of said outer ring unit and said overcap rotates therewith, and wherein said frictional contact may be overcome manually by holding one of said outer ring unit and said overcap and rotating the other of said outer ring unit and said overcap relative to one another; and, wherein when one of said outer ring unit and said overcap is held, and the other of said outer ring unit and said overcap is rotated to place said first alignment indicia and said second alignment indicia in alignment with one another, and then said gap lock is moved into said release position, said overcap may be removed from said outer ring unit to uncover said top dispenser of said container for use. 12.
