Abstract
Abstract A safety locking cap assembly for effecting closure of a bottle whereby inadvertent removal of the cap is prevented. A circular bottle neck is adapted to receive a cap and includes a radial projection. The cap includes an axially directed lug adapted to be positioned in interfering engagement with the radial projection by rotation of the cap in a first direction into closing engagement with the bottle neck to thereby prevent rotation of the cap in the other rotational direction. An axially directed finger is journaled to the cap and is adapted to cam the lug out of interfering engagement with the radial projection in response to radial alignment therebetween to thereby permit removal of the cap from the bottle neck by rotating same in the other rotational direction.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
130 words
A safety locking cap assembly comprising in combination a circular bottle neck adapted to rotatably receive a cap, said bottle neck including a radial projection, a cap including an axially directed lug adapted to be positioned in interfering engagement with said radial projection by rotation of said cap in a first direction into closing engagement with said bottle neck, thereby preventing rotation of said cap in the other rotational direction, and an axially directed finger rotatably disposed with respect to said cap and bottle neck and adapted to cam said lug out of interfering engagement with said radial projection in response to radial alignment between said lug and said finger to thereby permit removal of the cap from said bottle neck by rotation of same in the other rotational direction.
Claim 2
Dependent Claim
130 words
A safety locking cap assembly comprising in combination a circular bottle neck adapted to rotatably receive a cap, said bottle neck including a radial projection, a cap including an axially directed lug adapted to be positioned in interfering engagement with said radial projection by rotation of said cap in a first direction into closing engagement with said bottle neck, thereby preventing rotation of said cap in the other rotational direction, and an axially directed finger rotatably disposed with respect to said cap and bottle neck and adapted to cam said lug out of interfering engagement with said radial projection in response to radial alignment between said lug and said finger to thereby permit removal of the cap from said bottle neck by rotation of same in the other rotational direction.
Claim 3
Dependent Claim
20 words
A safety locking cap assembly as claimed in claim 1, wherein said axially directed finger is journaled to said cap.
Claim 4
Dependent Claim
39 words
A safety locking cap assembly as claimed in claim 2, wherein said cap includes indicia thereon radially aligned with said lug, alignment of said finger with said indicia effecting camming of said lug out of engagement with said projection.
Claim 5
Dependent Claim
100 words
A safety locking cap assembly as claimed in claim 2, wherein said finger include a first cam surface and a second cam surface, said first cam surface being adapted to cam said lug out of interfering engagement with said raDial projection in response to rotation of same in a first rotational direction, said other cam surface being adapted to maintain said finger in engagement with said projection and allow said finger to be cammed over said lug without removing the lug from interfering engagement with said radial projection in response to rotation of said finger in the other rotational direction.
Claim 6
Dependent Claim
43 words
A safety locking cap assembly as claimed in claim 2, wherein said circular bottle neck is threaded, and said cap includes internal threads to effect securing of the cap to the bottle neck by screwing of said cap in said first rotational direction.
Claim 7
Dependent Claim
72 words
A safety locking cap assembly as claimed in claim 2, wherein said projection includes an inclined surface for camming said lug thereover to prevent engagement therewith when said cap is rotated in said first rotational direction, and further includes a flat surface perpendicular to the tangent of said bottle neck to effect interfering engagement of said lug with said projection and thereby prevent rotation of said cap in said other rotational direction.
Claim 8
Dependent Claim
26 words
A safety locking cap assembly as claimed in claim 6, wherein the axial extent of said lug is substantially past the projection on said bottle neck.
Claim 9
Dependent Claim
26 words
A safety locking cap assembly as claimed in claim 7, wherein the axial extent of said finger is limited to prevent same from contacting said projection.
Claim 10
Dependent Claim
71 words
A safety locking cap assembly as claimed in claim 8, wherein said projection includes an inclined surface for camming said lug thereover to prevent engagement therewith when said cap is rotated in said first rotational direction, and further includes a flat surface perpendicular to the tangent of said bottle neck, to effect interfering engagement of said lug with said projection and prevent rotation of said cap in said other rotational direction.
Claim 11
Dependent Claim
100 words
A safety locking cap assembly as claimed in claim 9, wherein said finger include a first cam surface and a second cam surface, said first cam surface being adapted to cam said lug out of interfering engagement with said radial projection in response to rotation of same in a first rotational direction, said other cam surface being adapted to maintain said finger in engagement with said projection and allow said finger to be cammed over said lug without removing the lug from interfering engagement with said radial projection in response to rotation of said finger in the other rotational direction.
