Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
126 words
In a closure arrangement for a container having body and closure members with plastic rim portions, the combination of: (a) a tubular container member including a rim presenting a relatively flat, annular, axially outward facing, sealing surface; (b) a closure member including a rim presenting a relatively flat, annular, axially inward facing, sealing surface; (c) a relatively flat sealing membrane secured between said members and comprising: (i) a central panel formed of a relatively thin metallic foil; (ii) a heat activatable coating of plastic material on the inner surface of said central panel bonding said membrane to said container rim surface; (iii) a heat activatable coating of plastic material on the outer surface of said central panel bonding said membrane to said closure member rim surface.
Claim 2
Dependent Claim
126 words
In a closure arrangement for a container having body and closure members with plastic rim portions, the combination of: (a) a tubular container member including a rim presenting a relatively flat, annular, axially outward facing, sealing surface; (b) a closure member including a rim presenting a relatively flat, annular, axially inward facing, sealing surface; (c) a relatively flat sealing membrane secured between said members and comprising: (i) a central panel formed of a relatively thin metallic foil; (ii) a heat activatable coating of plastic material on the inner surface of said central panel bonding said membrane to said container rim surface; (iii) a heat activatable coating of plastic material on the outer surface of said central panel bonding said membrane to said closure member rim surface.
Claim 3
Dependent Claim
17 words
A closure arrangement according to claim 1, wherein said membrane is disposed substantially entirely in one plane.
Claim 4
Dependent Claim
17 words
A closure arrangement according to claim 1, wherein said membrane is disposed in more than one plane.
Claim 5
Dependent Claim
15 words
A closure arrangement according to claim 1, wherein said closure member includes a snap-on lid.
Claim 6
Dependent Claim
15 words
A closure arrangement according to claim 1, wherein said closure member includes a hinged lid.
Claim 7
Dependent Claim
15 words
A closure arrangement according to claim 1, wherein said closure member includes a screw-on lid.
Claim 8
Dependent Claim
44 words
A closure arrangement according to claim 1, wherein said closure member includes: (i) a radially outer rim element (ii) a radially inner rim element hingedly attached to said outer rim element; (iii) a central panel surrounded by and secured to said inner rim element.
Claim 9
Dependent Claim
84 words
A closure arrangement according to claim 7, wherein the heat activatable coating on the outer surface of said central panel forms a stronger bond with said closure member than the bond formed between the coating on the inner surface of said central panel and said container, so that when said inner rim element is moved away from said container the central portion of said membrane will separate from the remaining peripheral portion and will move away from said container member with said closure member.
