Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
141 words
In combination, a unitary molded thermoplastic closure comprising a disc shaped panel section, an annular skirt depending from the periphery thereof, helical threads formed on the inside annular surface of said skirt, and circumferentially spaced, axially extending slots formed through the threads of said skirt; and a cooperating container comprising an annular finish terminating in an annular rim, helical threads formed on the outside annular surface of said finish and cooperating with said threads on said skirt, means for effecting sealing engagement between said closure and said container finish, and a plurality of circumferentially spaced axially extending slots formed in the outside annular threaded surface of said finish, at least one of said closure slots being alignable with one of said finish slots by opening rotation of said closure sufficient to disengage said sealing means and permit venting of said container.
Claim 2
Dependent Claim
141 words
In combination, a unitary molded thermoplastic closure comprising a disc shaped panel section, an annular skirt depending from the periphery thereof, helical threads formed on the inside annular surface of said skirt, and circumferentially spaced, axially extending slots formed through the threads of said skirt; and a cooperating container comprising an annular finish terminating in an annular rim, helical threads formed on the outside annular surface of said finish and cooperating with said threads on said skirt, means for effecting sealing engagement between said closure and said container finish, and a plurality of circumferentially spaced axially extending slots formed in the outside annular threaded surface of said finish, at least one of said closure slots being alignable with one of said finish slots by opening rotation of said closure sufficient to disengage said sealing means and permit venting of said container.
Claim 3
Dependent Claim
45 words
The combination closure and container defined in claim 1 wherein said sealing means comprises an integral annular sealing plug depending from the inside surface of said panel and constructed and arranged to achieve a sealing interference fit within the inside annular surface of said finish.
Claim 4
Dependent Claim
28 words
The combination closure and container defined in claim 1 wherein the circumferential spacing of said closure slots corresponds to the circumferential spacing of said slots in said finish.
Claim 5
Dependent Claim
26 words
The combination closure and container defined in claim 1 wherein the axial slots in said finish have a depth greater than the depth of said threads.
Claim 6
Dependent Claim
29 words
The combination closure and container defined in claim 1 wherein the depth of said axial closure slots is equal to the depth of the threads formed in said skirt.
Claim 7
Dependent Claim
23 words
The combination closure and container defined in claim 1 wherein said closure slots are circumferentially wider than the slots formed in said finish.
Claim 8
Dependent Claim
78 words
The combination closure and container defined in claim 1 wherein said closure and finish slots are circumferentially spaced such that a first slot in said closure and a first slot in said finish are radially aligned during rotational removal of said closure from said finish when the seal formed by said sealing means against said finish is first broken, and additional ones of said slots in said closure and said finish are respectively sequentially aligned during further rotation.
Claim 9
Dependent Claim
58 words
The combination closure and container defined in claim 7 wherein said closure and finish slots are so aligned that a second slot in said closure and a second slot in said finish become radially aligned during rotation of said closure while said first slots are still aligned, whereby continuous venting through pairs of successively aligned slots is provided.
