Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
94 words
A paper towel or tissue product having a background embossing pattern comprising embossments spaced apart by substantially undeflected neutral planes wherein the embossments of the background embossing pattern have a major and minor axis and wherein the major axis of a majority of the embossments of the background embossing pattern is substantially aligned in the cross-machine direction of the product, whereby the cross-machine direction tensile strength of said product is greater than an otherwise identical product having the major axis of the embossments of its background embossing pattern aligned parallel to its machine direction.
Claim 2
Dependent Claim
94 words
A paper towel or tissue product having a background embossing pattern comprising embossments spaced apart by substantially undeflected neutral planes wherein the embossments of the background embossing pattern have a major and minor axis and wherein the major axis of a majority of the embossments of the background embossing pattern is substantially aligned in the cross-machine direction of the product, whereby the cross-machine direction tensile strength of said product is greater than an otherwise identical product having the major axis of the embossments of its background embossing pattern aligned parallel to its machine direction.
Claim 3
Dependent Claim
31 words
The paper sheet of claim 1 wherein the major axis of substantially all of the embossments of the background embossing pattern is substantially aligned in the cross-machine direction of the sheet.
Claim 4
Dependent Claim
19 words
The paper sheet of claim 1 wherein the embossments of the background emnbossing pattern are oval, rectangular, or diamond-shaped.
Claim 5
Dependent Claim
27 words
The paper sheet of claim 1 wherein the major axis of the embossments of the background embossing pattern is parallel to the cross-machine direction of the sheet.
Claim 6
Dependent Claim
27 words
The paper sheet of claim 4 wherein the spacing of the embossments of the background embossing pattern is at least as great as the minor axis dimension.
Claim 7
Dependent Claim
18 words
The paper sheet of claim 5 wherein the embossments of the background embossing pattern are oval in shape.
Claim 8
Dependent Claim
46 words
The paper sheet of claim 6 wherein the length of the major axis of the oval embossments is about 0.075 inch, the length of the minor axis of the oval embossments is about 0.035 inch, and the spacing between adjacent oval embossments is about 0.035 inch.
Claim 9
Dependent Claim
78 words
A two-ply paper towel having first and second sides and having a background embossing pattern thereon, said background embossing pattern comprising successive curvilinear rows of alternately protruding and depressed oval-shaped embossments oriented with the major axis of each oval aligned in the cross-machine direction of the towel and spaced apart by a substantially undeflected neutral plane wherein the depressed and protruding embossments of the first side correspond to the protruding and depressed embossments, respectively, of said second side.
Claim 10
Dependent Claim
78 words
A two-ply paper towel having first and second sides and having a background embossing pattern thereon, said background embossing pattern comprising successive curvilinear rows of alternately protruding and depressed oval-shaped embossments oriented with the major axis of each oval aligned in the cross-machine direction of the towel and spaced apart by a substantially undeflected neutral plane wherein the depressed and protruding embossments of the first side correspond to the protruding and depressed embossments, respectively, of said second side.
Claim 11
Dependent Claim
46 words
The paper towel of claim 8 wherein the background embossing pattern is intermittently interrupted by a design pattern containing oval-shaped protruding and depressed embossments having the major axis of the ovals aligned in a direction different than that of the ovals in the background embossing pattern.
Claim 12
Dependent Claim
13 words
The paper towel of claim 9 wherein the design pattern is a shamrock.
