Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
106 words
An article of manufacture comprising a roll of an elongated strip at least the surfaces of which are thermoplastic material wound in a multiplicity of convolutions and having a portion of the ultimate convolution fused solely by said thermoplastic material to the penultimate convolution and to no other convolution, providing a breakable connection between said two convolutions spaced from the free end of said strip providing a finger tab, said breakable connection having a maximum strength substantially less than the ultimate tensile strength of said strip at said breakable connection for the destruction of said connection without tearing said strip for unwinding said multiplicity of convolutions.
Claim 2
Dependent Claim
106 words
An article of manufacture comprising a roll of an elongated strip at least the surfaces of which are thermoplastic material wound in a multiplicity of convolutions and having a portion of the ultimate convolution fused solely by said thermoplastic material to the penultimate convolution and to no other convolution, providing a breakable connection between said two convolutions spaced from the free end of said strip providing a finger tab, said breakable connection having a maximum strength substantially less than the ultimate tensile strength of said strip at said breakable connection for the destruction of said connection without tearing said strip for unwinding said multiplicity of convolutions.
Claim 3
Dependent Claim
21 words
The article of manufacture as claimed in claim 1 wherein said elongated strip is substantially entirely composed of said thermoplastic material.
Claim 4
Dependent Claim
29 words
The article of manufacture as claimed in claim 2 wherein said breakable connection has a minimum strength capable of supporting said article when freely suspended from said finger tab.
Claim 5
Dependent Claim
26 words
The article of manufacture as claimed in claim 3 wherein said breakable connection comprises a narrow band extending across substantially the entire width of said strip.
Claim 6
Dependent Claim
16 words
The article of manufacture as claimed in claim 4 wherein said thermoplastic material is urethane foam.
Claim 7
Dependent Claim
16 words
The article of manufacture as claimed in claim 5 wherein said thermoplastic material is high-density polyethylene.
