Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
94 words
A closure comprising a top, a depending skirt, a first flange depending from the top and spaced from the skirt, and a resilient second flange on the depending skirt extending inwardly and which is deformable on moving the closure onto the finish of a container to conform against the outside side wall of the neck of the container and wherein said first flange is adapted to engage with said second flange to force said second flange into close conformity with the outside side wall or the top radius of the neck of the container.
Claim 2
Dependent Claim
94 words
A closure comprising a top, a depending skirt, a first flange depending from the top and spaced from the skirt, and a resilient second flange on the depending skirt extending inwardly and which is deformable on moving the closure onto the finish of a container to conform against the outside side wall of the neck of the container and wherein said first flange is adapted to engage with said second flange to force said second flange into close conformity with the outside side wall or the top radius of the neck of the container.
Claim 3
Dependent Claim
28 words
A closure as claimed in claim 1, wherein said second flange is so located as to be deformed upwardly and outwardly when moved onto the container from above.
Claim 4
Dependent Claim
27 words
A closure as claimed in claim 1, wherein said first flange and said second flange, when so engaged, at least in part define a closed annular chamber.
Claim 5
Dependent Claim
34 words
A closure as claimed in claim 3, wherein said first flange and said second flange are such that said chamber is adjacent, in use, the top seal surface of the finish of the container.
Claim 6
Dependent Claim
33 words
A closure as claimed in claim 1, wherein said resilient flange is so located that pressure within the container tending to escape will press said resilient flange into close conformity with said neck.
Claim 7
Dependent Claim
16 words
A closure as claimed in claim 1, including an abutment on the underside of the top.
Claim 8
Dependent Claim
26 words
A closure as claimed in claim 6, wherein the abutment is adapted to come into sealing abutting relation with the top seal surface of the container.
Claim 9
Dependent Claim
73 words
A closure as claimed in claim 7, wherein the abutment is such as to space the top, in use, above the top seal surface so that after the abutting relation is established further downward movement of the skirt onto the container will cause a pivoting about the abutment having an inward component of motion which will more tightly than otherwise force said resilient flange and said first flange into engagement with the container.
Claim 10
Dependent Claim
48 words
A closure as claimed in claim 1, wherein said first flange is such that doming of the closure in use in consequence of internal pressure within the container will cause an inward component of motion of said first flange which will more tightly than otherwise seal the container.
