Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 91 words
In combination, a bottle having a neck portion and being threaded along said neck portion to receive a closure cap, a resilient biasing member carried on said neck portion and extending radially outwardly therefrom, a locking member disposed about said neck portion and engaging said resilient member adjacent its lower portion, means defined on said locking member and said cap for interlocking engagement therebetween, said member upon tightening of said cap on said neck forcing said resilient member downwardly whereby said resilient member biases said locking member toward said interlocking engagement.
Claim 2
Dependent Claim 91 words
In combination, a bottle having a neck portion and being threaded along said neck portion to receive a closure cap, a resilient biasing member carried on said neck portion and extending radially outwardly therefrom, a locking member disposed about said neck portion and engaging said resilient member adjacent its lower portion, means defined on said locking member and said cap for interlocking engagement therebetween, said member upon tightening of said cap on said neck forcing said resilient member downwardly whereby said resilient member biases said locking member toward said interlocking engagement.
Claim 3
Dependent Claim 29 words
The combination of claim 1 further defined in that the bottle is formed of a resilient material and said biasing member is a flange integrally formed on said neck.
Claim 4
Dependent Claim 34 words
The combination of claim 1 further including splinelike members on said neck above said biasing member, said locking member fitting over said splines to render said locking member nonrotational with respect to said neck.
Claim 5
Dependent Claim 57 words
The combination of claim 1 wherein said interlocking means comprise mating ratchetlike teeth defined on said locking member and said closure cap, said teeth being arranged to permit slippage therebetween as said closure cap is threaded onto said neck and prevent rotation of said cap from said neck when said locking member is biased against said cap.
Claim 6
Dependent Claim 42 words
The combination of claim 2 wherein said locking member is annular in shape and the underside thereof is defined with a concavity so that said locking member may act on the outer edges of said flange and move downwardly with respect thereto.
Claim 7
Dependent Claim 39 words
The combination of claim 3 wherein said locking member defines an opening for receiving said neck therethrough, a plurality of angularly spaced detent elements extending radially inwardly of said opening and defining spaces therebetween adapted to receive said splines.
Claim 8
Dependent Claim 28 words
The combination of claim 1 wherein said bottle is formed of glass and said biasing member is of a resilient material disposed about the neck of said bottle.
Claim 9
Dependent Claim 36 words
The combination of claim 7 wherein the neck portion of said bottle is formed with a flangelike bead, said biasing member includes a sleevelike portion resting on said bead and having a resilient radially extending flange.
Claim 10
Dependent Claim 34 words
The combination of claim 7 further including splinelike members on said neck above said biasing member, said locking member fitting over said splines to render said locking member nonrotational with respect to said neck.
Claim 11
Dependent Claim 57 words
The combination of claim 8 wherein said interlocking means comprise mating ratchetlike teeth defined on said locking member and said closure cap, said teeth being arranged to permit slippage therebetween as said closure cap is threaded onto said neck and prevent rotation of said cap from said neck when said locking member is biased against said cap.
Claim 12
Dependent Claim 42 words
The combination of claim 8 wherein said locking member is annular in shape and the underside thereof is defined with a concavity so that said locking member may act on the outer edges of said flange and move downwardly with respect thereto.
Claim 13
Dependent Claim 51 words
The combination of claim 7 wherein said locking member defines an opening for receiving said neck therethrough, a plurality of splines defined on the neck of said bottle and a plurality of angularly spaced detent elements extending radially inwardly of said opening and defining spaces therebetween adapted to receive said splines.
