Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
132 words
A multi-layered tissue comprising: (a) a first layer of creped cellulose wadding; (b) a second layer of creped cellulose wadding; and (c) a layer of plastic film disposed between said first and second layers; wherein said film is unbonded to said first layer, except where the film and first layer are bonded together along their common edges sufficiently to maintain the integrity of the tissue, and wherein said film is unbonded or lightly and uniformly bonded to said second layer, except where the film and the second layer are bonded together along their common edges sufficiently to maintain the integrity of the tissue, such that in all areas of the tissue other than said bonded edges the film can be peeled away from the first and second layer without rupturing either layer.
Claim 2
Dependent Claim
132 words
A multi-layered tissue comprising: (a) a first layer of creped cellulose wadding; (b) a second layer of creped cellulose wadding; and (c) a layer of plastic film disposed between said first and second layers; wherein said film is unbonded to said first layer, except where the film and first layer are bonded together along their common edges sufficiently to maintain the integrity of the tissue, and wherein said film is unbonded or lightly and uniformly bonded to said second layer, except where the film and the second layer are bonded together along their common edges sufficiently to maintain the integrity of the tissue, such that in all areas of the tissue other than said bonded edges the film can be peeled away from the first and second layer without rupturing either layer.
Claim 3
Dependent Claim
35 words
The multi-layered tissue of claim 1 wherein the film is unbonded to both the first and second layers, except where the film and the first and second layers are bonded together along their common edges.
Claim 4
Dependent Claim
33 words
The multi-layered tissue of claim 1 wherein the film is lightly and uniformly bonded to the second layer, except where the film and the second layer are bonded together along their common edges.
Claim 5
Dependent Claim
14 words
The tissue of claim 3 wherein said first and second layers are outer layers.
Claim 6
Dependent Claim
11 words
The tissue of claim 4 wherein the plastic film is thermoplastic.
Claim 7
Dependent Claim
11 words
The tissue of claim 5 wherein the plastic film is polyethylene.
Claim 8
Dependent Claim
18 words
The tissue of claim 6 wherein the thickness of the polyethylene film is less than about 0.0005 inch.
Claim 9
Dependent Claim
18 words
The tissue of claim 7 wherein the thickness of the plastic film is about 0.00025 inch or less.
Claim 10
Dependent Claim
18 words
The tissue of claim 7 wherein the thickness of the plastic film is about 0.0001 inch or less.
Claim 11
Dependent Claim
28 words
The tissue of claim 7 wherein the basis weight of the first and second outer layers is from about 8 to about 15 pounds per 2880 square feet.
Claim 12
Dependent Claim
28 words
The tissue of claim 10 wherein the integrity of the multi-layered tissue is maintained by crimping the tissue along or near at least one edge of the tissue.
Claim 13
Dependent Claim
154 words
A three-layered tissue comprising: (a) a first layer of creped cellulose wadding having a basis weight of about 8-15 pounds per 2880 square feet; (b) a second layer of creped cellulose wadding having a basis weight of about 8-15 pounds per square foot; and (c) a layer of polyethylene film having a thickness of about 0.00025 inch or less disposed between said first and second layers; wherein said film is unbonded to said first layer, except where the film and first layer are crimped together along their common edges sufficiently to maintain the integrity of the tissue, and wherein said film is lightly and uniformly bonded to said second layer, except where the film and the second layer are crimped together along their common edges to sufficiently maintain the integrity of the tissue, such that in the uncrimped areas the film can be peeled away from the second layer without rupturing said second layer.
Claim 14
Dependent Claim
154 words
A three-layered tissue comprising: (a) a first layer of creped cellulose wadding having a basis weight of about 8-15 pounds per 2880 square feet; (b) a second layer of creped cellulose wadding having a basis weight of about 8-15 pounds per square foot; and (c) a layer of polyethylene film having a thickness of about 0.00025 inch or less disposed between said first and second layers; wherein said film is unbonded to said first layer, except where the film and first layer are crimped together along their common edges sufficiently to maintain the integrity of the tissue, and wherein said film is lightly and uniformly bonded to said second layer, except where the film and the second layer are crimped together along their common edges to sufficiently maintain the integrity of the tissue, such that in the uncrimped areas the film can be peeled away from the second layer without rupturing said second layer.
