Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
116 words
A plastically deformable tube, comprising a sheet of laminated web defining a first edge zone and a second edge zone, said web including a layer of orientation-stretched polyester, a layer of metal foil and a first surface layer of glycol-modified polyester adjacent said layer of orientation-stretched polyester, a second surface layer of glycol-modified polyester adjacent said layer of metal foil, said layer of metal foil being receded from a first edge zone of said sheet, said sheet being folded to form a tubular element with said first edge zone and said second edge zone overlapping, said first surface layer of said second edge zone being bonded to said second surface layer of said first edge zone.
Claim 2
Dependent Claim
116 words
A plastically deformable tube, comprising a sheet of laminated web defining a first edge zone and a second edge zone, said web including a layer of orientation-stretched polyester, a layer of metal foil and a first surface layer of glycol-modified polyester adjacent said layer of orientation-stretched polyester, a second surface layer of glycol-modified polyester adjacent said layer of metal foil, said layer of metal foil being receded from a first edge zone of said sheet, said sheet being folded to form a tubular element with said first edge zone and said second edge zone overlapping, said first surface layer of said second edge zone being bonded to said second surface layer of said first edge zone.
Claim 3
Dependent Claim
16 words
The tubular element in accordance with claim 1, wherein said layer of metal foil is aluminum.
Claim 4
Dependent Claim
17 words
