Abstract
Abstract This disclosure relates to a novel packaging method which includes the steps of packaging a product into a container having a mouth defined by a lip, inserting a metallic-nonmetallicmetallic laminated liner upon the container lip in sandwiched relationship between the container lip and an end panel of an associated closure, and inducing heat in the metallic laminate sufficient to fuse one of the metallic laminates to the closure end panel and the other of the metallic laminates to the container lip. Preferably the bond strength between the other of the metallic laminates and the container lip is great enough to resist delamination upon the removal of the closure to thus provide an inner seal. Additionally, the bond strength between the one metallic laminate and the end panel is sufficiently strong to retain the non-metallic laminate with the closure upon the removal thereof whereby the nonmetallic laminate can be used for resealing purposes after the closure has been once removed from the container.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
75 words
A packaging method comprising the steps of packaging a product in a containEr having a mouth defined by a lip, inserting a metallic-nonmetallic-metallic laminated liner upon the container lip in sandwiched relationship between the container lip and an end panel of an associated closure, and inducing heat in the metallic laminates sufficient to fuse one of the metallic laminates to the closure end panel and the other of the metallic laminates to the container lip.
Claim 2
Dependent Claim
75 words
A packaging method comprising the steps of packaging a product in a containEr having a mouth defined by a lip, inserting a metallic-nonmetallic-metallic laminated liner upon the container lip in sandwiched relationship between the container lip and an end panel of an associated closure, and inducing heat in the metallic laminates sufficient to fuse one of the metallic laminates to the closure end panel and the other of the metallic laminates to the container lip.
Claim 3
Dependent Claim
65 words
The packaging method as defined in claim 1 including the step of constructing the metallic-nonmetallic-metallic laminated liner such that the bond strength between said other metallic laminate and said container lip is greater than the bond strength between said other metallic laminate and said nonmetallic laminate whereby upon the attempted removal of said liner and other metallic laminate will remain adhered to said container lip.
Claim 4
Dependent Claim
67 words
The packaging method as defined in claim 1 including the step of constructing the metallic-nonmetallic-metallic laminate liner such that the bond strength between said one metallic laminate and said closure end panel is greater than the bond strength between said other metallic laminate and said nonmetallic laminate whereby upon the attempted removal of said liner said one metallic laminate will remain adhered to said closure end panel.
Claim 5
Dependent Claim
74 words
The packaging method as defined in claim 1 wherein the one metallic laminate is fused to the closure end panel with a first bond strength greater than a second bond strength between said one metallic laminate and said nonmetallic laminate and a third bond strength between said other metallic laminate, and said other metallic laminate is fused to the container lip with a fourth bond strength greater than said first through third bond strengths.
Claim 6
Dependent Claim
43 words
The packaging method as defined in claim 4 wherein said third bond strength is weaker than said first, second and fourth bond strengths whereby upon the removal of said closure said liner will delaminate between the other metallic laminate and the nonmetallic laminate.
Claim 7
Dependent Claim
43 words
The packaging method as defined in claim 5 wherein the first and second bond strengths are greater than the third bond strength whereby upon the removal of said closure said one metallic laminate and said nonmetallic laminate will remain adhered to said closure.
Claim 8
Dependent Claim
110 words
A packaging method comprising the steps of providing a closure having an end panel and a peripheral skirt, providing a liner as at least a metallic-nonmetallic laminate, assembling the liner within the closure with the metallic laminate proximate the closure end panel, inducing heat in the metallic laminate sufficient to fuse the same to the end panel whereby during subsequent handling, storage, shipment, etc. the components will not accidentally disunite, shipping the united closure and liner to a packager, providing a container having a mouth defined by a lip, packaging a product in the container, and assembling the closure upon the container with the nonmetallic laminate upon the container lip.
Claim 9
Dependent Claim
110 words
A packaging method comprising the steps of providing a closure having an end panel and a peripheral skirt, providing a liner as at least a metallic-nonmetallic laminate, assembling the liner within the closure with the metallic laminate proximate the closure end panel, inducing heat in the metallic laminate sufficient to fuse the same to the end panel whereby during subsequent handling, storage, shipment, etc. the components will not accidentally disunite, shipping the united closure and liner to a packager, providing a container having a mouth defined by a lip, packaging a product in the container, and assembling the closure upon the container with the nonmetallic laminate upon the container lip.
Claim 10
Dependent Claim
134 words
A packaging method comprising the steps of providing a closure having an end panel and a peripheral skirt, providing a liner as at least a metallic-nonmetallic-metallic laminate, assembling the liner within the closure with one of the metallic laminates proximate the closure end panel, inducing heat in the one metallic laminate sufficient to fuse the one metallic laminate to the end panel whereby during subsequent handling, storage, shipment, etc. the components will not accidentally disunite, shipping the united closure and liner to a packager, providing a container having a mouth defined by a lip, packaging a product in the container, assembling the closure upon the container with the other metallic laminate proximate the container lip, and inducing heat at least in the other metallic laminate sufficient to fuse the same to the container lip.
Claim 11
Dependent Claim
134 words
A packaging method comprising the steps of providing a closure having an end panel and a peripheral skirt, providing a liner as at least a metallic-nonmetallic-metallic laminate, assembling the liner within the closure with one of the metallic laminates proximate the closure end panel, inducing heat in the one metallic laminate sufficient to fuse the one metallic laminate to the end panel whereby during subsequent handling, storage, shipment, etc. the components will not accidentally disunite, shipping the united closure and liner to a packager, providing a container having a mouth defined by a lip, packaging a product in the container, assembling the closure upon the container with the other metallic laminate proximate the container lip, and inducing heat at least in the other metallic laminate sufficient to fuse the same to the container lip.
Claim 12
Dependent Claim
24 words
The method as defined in claim 8 including the step of mechanically retaining the liner in the closure prior to the heat inducing step.
Claim 13
Dependent Claim
48 words
The method as defined in claim 8 inCluding the step of mechanically retaining the liner in the closure prior to the heat inducing step, said retaining step being performed by adhesive bonding the one metallic laminate to the closure end panel prior to the first heat inducing step.
Claim 14
Dependent Claim
47 words
The method as defined in claim 8 including the step of mechanically retaining the liner in the closure prior to the heat inducing step, said retaining step being performed by mechanically interlocking the periphery of the liner within the closure prior to the first heat inducing step.
