Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
144 words
In combination, a container having a sidewall terminating in a lip, a cooperating container closure having a sidewall and at least one locking spring clip, said clip defining a strip of resilient material having a pair of spaced, generally paralled legs, and said legs being operable to straddle said sidewall and said lip, one leg of said pair being formed with a shoulder operable to make a locking connection with said lip, said legs being spring biased toward one another so that said one leg of the clip is movable from a first or normal position in which said shoulder makes a locking connection with said lip to a second position in which said shoulder is free of said lip and abutts said closure sidewall operative to limit the stroke of said one leg to avoid without exceeding the elastic limit of said clip.
Claim 2
Dependent Claim
144 words
In combination, a container having a sidewall terminating in a lip, a cooperating container closure having a sidewall and at least one locking spring clip, said clip defining a strip of resilient material having a pair of spaced, generally paralled legs, and said legs being operable to straddle said sidewall and said lip, one leg of said pair being formed with a shoulder operable to make a locking connection with said lip, said legs being spring biased toward one another so that said one leg of the clip is movable from a first or normal position in which said shoulder makes a locking connection with said lip to a second position in which said shoulder is free of said lip and abutts said closure sidewall operative to limit the stroke of said one leg to avoid without exceeding the elastic limit of said clip.
Claim 3
Dependent Claim
14 words
The combination of claim 1 in which the clip is secured to the closure.
Claim 4
Dependent Claim
32 words
The combination of claim 1 in which a plurality of clips cooperate with a given container and its closure to effect a plurality of locking connections between a container and its closures.
Claim 5
Dependent Claim
16 words
A combination of claim 1 in which the locking spring clip is fabricated of spring steel.
Claim 6
Dependent Claim
16 words
The combination of claim 1 in which the clip is fabricated of a resilient plastic material.
Claim 7
Dependent Claim
14 words
The combination of claim 1 in which the clip is riveted to the closure.
Claim 8
Dependent Claim
97 words
A clip device for securing a closure to a container where the container is formed with a sidewall terminating in a rim or lip comprising a resilient strip of deformable material having a pair of spaced, generally parallel legs, said legs being joined by a saddle portion and being resiliantly biased so as to resist separation, one leg of said pair being formed with a locking shoulder normally operable to make a locking connection with said rim, said leg being movable with a limited stroke against said bias to a second position to break said locking connection.
Claim 9
Dependent Claim
97 words
