Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
82 words
A laminated liner element for a closure cap, said liner element comprising: a barrier layer of pliant polymerized ethylene/vinyl acetate copolymer material possessing the properties of being essentially impermeable to water vapors and gaseous substances; a backing layer of surface-sorbent material selected from the group comprising cloth fabric, cellulosic material, paper or paper-like material and having an outer face surface-bonded to said barrier layer, and having an inner face adaptable to be bonded to the interior endwall surface of said closure cap.
Claim 2
Dependent Claim
82 words
A laminated liner element for a closure cap, said liner element comprising: a barrier layer of pliant polymerized ethylene/vinyl acetate copolymer material possessing the properties of being essentially impermeable to water vapors and gaseous substances; a backing layer of surface-sorbent material selected from the group comprising cloth fabric, cellulosic material, paper or paper-like material and having an outer face surface-bonded to said barrier layer, and having an inner face adaptable to be bonded to the interior endwall surface of said closure cap.
Claim 3
Dependent Claim
16 words
A laminated liner element as defined in claim 1, wherein said barrier layer is essentially transparent.
Claim 4
Dependent Claim
30 words
A laminated liner element as defined in claim 2, wherein said outer face includes a distinctive marking applied thereon, and wherein said marking is visibly discernible through said barrier layer.
Claim 5
Dependent Claim
63 words
A laminated liner element as defined in claim 3, wherein said backing layer is adapted to bond less tenaciously to said interior endwall surface of said closure cap than to said barrier layer, whereby said backing layer will preferentially separate from said interior endwall surface and accompany said barrier layer in response to forceful removal of said liner element from said closure cap.
Claim 6
Dependent Claim
44 words
A laminated liner element as defined in claim 1, wherein said barrier layer possesses a thickness in the range of between about 0.025 and 0.035 inch, and wherein said backing layer possesses a thickness in the range of between about 0.002 and 0.008 inch.
Claim 7
Dependent Claim
156 words
In a closure cap for establishing and maintaining hermetic sealability against the dispensing end of a bottle, said closure cap including an interior endwall and sidewall surface, an organic sizing material bonded to and coextensive with said endwall and sidewall surface and a laminated liner element, the improvement wherein said liner element comprises: a backing layer of surface-sorbent material selected from the group comprising cloth fabric, cellulosic material, paper or paper-like material and having an inner face confronting and bonded to the sizing material on said endwall surface, and having an oppositely facing outer face, and a barrier layer of pliant polymerized ethylene/vinyl acetate copolymer material possessing the properties of being substantially transparent and essentially impermeable to water vapors and gaseous substances, said barrier layer being surface-bonded to the outer face of said backing layer, and a distinctive marking applied on said outer face of said surface-sorbent material and being visibly discernible through said barrier layer.
Claim 8
Dependent Claim
156 words
In a closure cap for establishing and maintaining hermetic sealability against the dispensing end of a bottle, said closure cap including an interior endwall and sidewall surface, an organic sizing material bonded to and coextensive with said endwall and sidewall surface and a laminated liner element, the improvement wherein said liner element comprises: a backing layer of surface-sorbent material selected from the group comprising cloth fabric, cellulosic material, paper or paper-like material and having an inner face confronting and bonded to the sizing material on said endwall surface, and having an oppositely facing outer face, and a barrier layer of pliant polymerized ethylene/vinyl acetate copolymer material possessing the properties of being substantially transparent and essentially impermeable to water vapors and gaseous substances, said barrier layer being surface-bonded to the outer face of said backing layer, and a distinctive marking applied on said outer face of said surface-sorbent material and being visibly discernible through said barrier layer.
Claim 9
Dependent Claim
81 words
A closure cap as defined in claim 6, wherein the bond between the inner face of said backing layer and the sizing material is preselectively weaker than the bond between said barrier layer and the outer face of said backing layer, to thereby selectively accommodate forceful separation of said backing layer from said closure cap without impairing the distinctive marking on the outer face of said backing layer and without impairing the bond between said backing layer and said barrier layer.
