Child resistant cap with safety collar and enhancement

Abstract

A child resistant cap includes: (a) a main closure base; (b) an outer ring 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 is attached to the base. The overcap has protrusions and the ring has corresponding cut outs. Because the overcap and ring are frictionally engaged, when one rotates, the other rotates with it. They must be held separately and rotated relative to one another to effect proper alignment for overcap remove and container dispensing. In some embodiments, the base is eliminated and the ring is attached directly to a container rim.

1 . A child resistant cap with safety collar and enhancement, which comprises:
 a) a main closure base for attachment to a container, said base having a top portion having a circular horizontal track thereon for attachment with an outer ring;   b) an outer ring having a circular inside wall with a horizontal track thereon for attachment to the track of said base so as to connect said outer ring to said base so as to be horizontally and freely rotatable thereabout, said outer ring also having a top with an outwardly biased ledge for retaining an overcap, and having at least two cut outs on said ledge to permit an overcap to be inserted onto and removed from said outer ring, and 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;   c) a dispensing mechanism at the top of said base and extending therethrough for insertion into a container;   d) an overcap having a circular bottom adapted to be inserted into said outer ring and over said dispensing mechanism, said bottom having at least two protrusions thereon which have geometries of adequate size to freely move through said at least one of said at least two cut outs of said ledge of said outer ring and when said overcap is so inserted and rotated, of adequate size and geometry to prevent removal of said overcap from said outer ring, except when said at least two protrusions and said at least two cut outs are in proper alignment, said overcap having at least two opposing griping pads located on its exterior; and,    further wherein said outer ring ledge has an underside and said at least two protrusions of said overcap have tops wherein the underside of said ledge and the top side of said at least two protrusions are in frictional contact with one another when said overcap is inserted into said outer ring such that when one of said outer ring and said overcap are rotated, the other of said outer ring and said overcap rotates therewith, and wherein said frictional contact may be overcome manually by holding one of said outer ring and said overcap and rotating the other of said outer ring and said overcap.

         7 . The child resistant cap with safety collar and enhancement of  claim 1  wherein said there are at least three cut outs and a corresponding number of protrusions, said cut outs and protrusions being evenly spaced from one another. 
     
     
         8 . The child resistant cap with safety collar and enhancement of  claim 1  wherein said underside of said ledge and said top of said at least one protrusions have non-smooth topographies to enhance said frictional contact. 
     
     
         9 . The child resistant cap with safety collar and enhancement of  claim 1  wherein at least one of said ledge and said at least two protrusions two 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 outs, and are upwardly inflexible so as to prevent removal of said overcap from said outer ring, except when said at least two protrusions and said at least two cut outs are in proper alignment. 
     
     
         10 . The child resistant cap with safety collar and enhancement of  claim 1  wherein said overcap further includes a plurality of vertical friction pads located on its inside and positioned to be adjacent the outside of said ledge when on said outer ring. 
     
     
         11 . A child resistant cap with safety collar and enhancement for direct attachment to a container having a rim of greater diameter than its neck, which comprises:
 a) an outer ring having a circular inside wall with a horizontal track thereon for attachment to the rim of a container having a rim of greater diameter than its adjacent neck, said container having a top dispenser, so as to connect said outer ring to said rim so as to be horizontally and freely rotatable thereabout, said outer ring also having a top with an outwardly biased ledge for retaining an overcap, and having at least two cut outs on said ledge to permit an overcap to be inserted onto and removed from said outer ring, and 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;   b) an overcap having a circular bottom adapted to be inserted into said outer ring and over said container, said bottom having at least two protrusions thereon which have geometries of adequate size to freely move through said at least one of said at least two cut outs of said ledge of said outer ring and when said overcap is so inserted and rotated, of adequate size and geometry to prevent removal of said overcap from said outer ring, except when said at least two protrusions and said at least two cut outs are in proper alignment, said overcap having at least two opposing griping pads located on its exterior; and,    further wherein said outer ring ledge has an underside and said at least two protrusions of said overcap have tops wherein the underside of said ledge and the top side of said at least two protrusions are in frictional contact with one another when said overcap is inserted into said outer ring such that when one of said outer ring and said overcap are rotated, the other of said outer ring and said overcap rotates therewith, and wherein said frictional contact may be overcome manually by holding one of said outer ring and said overcap and rotating the other of said outer ring and said overcap.
