Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 101 words
A safety closure for standard screw top containers comprising a snap ring mounted on the neck of a container, said snap ring having a plurality of upstanding locking tabs spaced at equal intervals about the ring, a removable cap engaged over said locking tabs, an outwardly opening annular recess within the periphery of said cap, and a continuous locking ring rotatably mounted in said recess, said locking tabs engaged over said locking ring to secure said cap, and said locking ring having relief areas coincident with said locking tabs in one relative position of such ring whereby to release said cap.
Claim 2
Dependent Claim 101 words
A safety closure for standard screw top containers comprising a snap ring mounted on the neck of a container, said snap ring having a plurality of upstanding locking tabs spaced at equal intervals about the ring, a removable cap engaged over said locking tabs, an outwardly opening annular recess within the periphery of said cap, and a continuous locking ring rotatably mounted in said recess, said locking tabs engaged over said locking ring to secure said cap, and said locking ring having relief areas coincident with said locking tabs in one relative position of such ring whereby to release said cap.
Claim 3
Dependent Claim 73 words
The safety closure of claim 1 wherein said removable cap has a plurality of annular continuous locking rings in said annular recess, and said locking tabs having means engaged over the respective locking rings to secure the cap, said locking rings each having relief areas coincident with the locking tabs in one relative position of such rings whereby when all of the locking rings are in said relative position the cap is released.
Claim 4
Dependent Claim 30 words
The safety closure of claim 2 wherein the several locking rings include indicia whereby the coincidental release position of the rings may be dialed by bringing certain indicia into registry.
Claim 5
Dependent Claim 54 words
The safety closure of claim 1 wherein said locking cap is provided with two annular continuous locking rings in said recess, said locking tabs each having two recesses respectively for receiving said locking rings, and said locking rings each having relief areas coincident with locking tabs in one relative position of the locking rings.
Claim 6
Dependent Claim 30 words
The safety closure of claim 4 wherein the locking rings each include indicia whereby the coincidental release position of such rings may be dialed by bringing certain indicia into registry.
Claim 7
Dependent Claim 53 words
The safety closure of claim 1 wherein the locking cap is provided with three continuous locking rings in said recess, said locking tabs each having three grooves for receiving said locking rings, and said locking rings each having relief areas coincident with the locking tabs in one relative position of the locking rings.
Claim 8
Dependent Claim 30 words
The safety closure of claim 6 wherein the locking rings each include indicia whereby the coincidental release position of such rings may be dialed by bringing certain indicia into registry.
Claim 9
Dependent Claim 93 words
The safety closure of claim 1 wherein the locking cap has four continuous locking rings in said recess, said locking tabs each having four grooves for receiving said locking rings, and said locking rings each having relief areas coincident with the locking tabs in one position of the several locking rings relative to the locking tabs whereby any one of the locking rings having its relief areas displaced from said one position will lock the cap and all such rings must have their relief areas coincident with the tabs to release the cap.
Claim 10
Dependent Claim 32 words
The safety closure of claim 8 wherein the locking rings each include indicia whereby the coincidental release position may be dialed by bringing certain indicia on the several locking rings into registry.
Claim 11
Dependent Claim 17 words
The safety closure of claim 9 wherein said locking tabs are disposed diametrically opposite to each other.
Claim 12
Dependent Claim 40 words
The safety closure of claim 1 wherein said snap ring has a plurality of inwardly open radially disposed slots providing relatively flexible container-engaging-portions therebetween whereby to facilitate application and fitting of the snap ring on the neck of the container.
Claim 13
Dependent Claim 43 words
The safety closure of claim 1 wherein said upstanding locking tabs extend into cut-outs in said cap in the area of said annular recess whereby at least a portion of each locking tab is disposed substantially flush with the surface of the recess.
Claim 14
Dependent Claim 34 words
The safety closure of claim 12 wherein the cut-outs in the cap extend into a bottom flange on the cap whereby to provide clearance over portions of the locking tabs upon removing the cap.
