Child resistant reminder closure

Abstract

A child resistant reminder closure comprising an outer closure member having a base wall and a peripheral skirt, an inner closure member having a base wall and peripheral skirt with a bead on the outer closure member retaining the inner closure member against limited axial outward movement relative to the outer closure member. An assembly of a day disk and an indexing disk is provided in the outer closure member and is rotatable relative thereto. A first set of flexible radial ratcheting fingers extend radially from the day disk and engage radial lugs on the undersurface of the base wall of the outer closure member. A second set of flexible radial ratcheting fingers extend radially from the day disk and engage circumferentially spaced lugs on the upper surface of the indexing disk. Axially interengageable lugs and recesses are provided on the outer closure member and the indexing disk and interengaging lugs and recesses are provided between the indexing disk and inner closure member which are interengaged to remove the closure or to apply the closure to s container thereby providing a child resistant feature. A window is provided on the outer closure member and is associated with indicia on the day disk to indicate the circumferential position of the outer closure member relative to the day disk.

       2. The child resistant reminder closure set forth in claim 1 wherein said first set of flexible radial ratcheting means on said day disk comprise flexible fingers extending circumferentially in one direction and having free ends, said second of said set of flexible radial ratcheting means comprising a plurality of circumferentially extending flexible fingers extending circumferentially in the same direction as the first set of fingers .[.and.]. .Iadd., said first set being .Iaddend.positioned on .[.and.]. .Iadd.the .Iaddend.opening in said day disk. 
     
     
       3. The child resistant reminder closure set forth in claim 2 wherein .[.one.]. said .Iadd.set of rotationally interengageable means between said outer closure member and said indexing disk comprises a third .Iaddend.set of .[.said.]. lugs on said outer closure member .[.is.]. positioned at the juncture of the base wall and peripheral skirt of said outer closure member .[.the other set of lugs is.]. said set of lugs is .Iadd., said first set of lugs on said closure member engaging said first set of flexible fingers being .Iaddend.positioned on the periphery of a cylindrical surface extending downwardly from the base wall of said outer closure member. 
     
     
       4. The child resistant reminder closure set forth in claim 3 wherein said means on said indexing disk engageable with the .[.first.]. .Iadd.second .Iaddend.set of flexible fingers on said day disk comprise lugs on said indexing disk extending toward said base wall of said outer closure and having, recesses therein engaging the free ends of the .[.first.]. .Iadd.second .Iaddend.set of flexible fingers comprising the first set of ratcheting means.Iadd.. .Iaddend..[., said one set of lugs on said outer closure member being adapted to engage said lugs on said indexing ring when the outer closure member is rotated in either direction..]. 
     
     
       5. The child resistant reminder closure set forth in claim 4 wherein said .[.second.]. set of axially interengageable .Iadd.child resistant .Iaddend.means between said indexing disk and said inner closure member comprises a fourth set of lugs on the underside of said indexing disk and a .Iadd.and a fifth set of .Iaddend.circumferentially .Iadd.spaced .Iaddend.lugs on the top surface of said base wall of said inner closure member, said .Iadd.fourth set of .Iaddend.lugs on the underside of the indexing disk being adapted to extend between the recesses of said .Iadd.fifth set of .Iaddend.lugs on the inner closure member when the outer closure member is moved axially toward the inner closure member and to engage the fourth set of lugs on the inner closure member when the outer closure member is rotated to apply or remove the closure from a container.
