Sanitary Tissue Products Comprising a Surface Pattern

Abstract

Sanitary tissue products having a surface pattern for better wet properties and/or cleaning properties.

What is claimed is: 
     
         1 . A sanitary tissue product comprising a surface pattern having a repeating design element, wherein the repeating design element contains a first rhombus element having larger dimension and smaller dimension such that it exhibits an aspect ratio of greater than 1.25, wherein the first rhombus element is positioned between a first set of two lines formed by a plurality of variable-sized discrete depressions, wherein the variable-sized discrete depressions are arranged in a periodic sequence based on size of the discrete depressions, wherein the two lines are symmetrical to one another along the rhombus element's largest dimension. 
     
     
         2 . The sanitary tissue product according to  claim 1  wherein the two lines of the first set are curvilinear such that the combination of the two lines of the first set forms a first node within which the rhombus element is positioned. 
     
     
         3 . The sanitary tissue product according to  claim 1  wherein at least one line of the first set comprises one or more inflection points along the length of the line of the first set. 
     
     
         4 . The sanitary tissue product according to  claim 3  wherein at least one of the inflection points comprises a minimum-sized discrete depression within the at least one line of the first set. 
     
     
         5 . The sanitary tissue product according to  claim 3  wherein at least one of the inflection points comprises a maximum-sized discrete depression within the at least one line of the first set. 
     
     
         6 . The sanitary tissue product according to  claim 1  wherein the two lines of the first set are asymptotic to one another. 
     
     
         7 . The sanitary tissue product according to  claim 1  wherein the repeating design element further comprises a second set of two lines formed by a plurality of variable-sized discrete depressions, wherein the variable-sized discrete depressions are arranged in a periodic sequence based on size of the discrete depressions, wherein the two lines of the second set are symmetrical to one another along the rhombus element's largest dimension. 
     
     
         8 . The sanitary tissue product according to  claim 7  wherein the two lines of the second set are curvilinear such that the combination of the two lines of the second set forms a second node within which the first node formed by the combination of the two lines of the first set is positioned. 
     
     
         9 . The sanitary tissue product according to  claim 7  wherein at least one line of the second set comprises one or more inflection points along the length of the line of the second set. 
     
     
         10 . The sanitary tissue product according to  claim 7  wherein the two lines of the second set of two lines are asymptotic to one another. 
     
     
         11 . The sanitary tissue product according to  claim 7  wherein the lines of the first set of two lines exhibit a periodic sequence that is different from the lines of the second set of two lines. 
     
     
         12 . The sanitary tissue product according to  claim 7  wherein the first and second set of lines are equally distanced from one another. 
     
     
         13 . The sanitary tissue product according to  claim 7  wherein at least one line of the first set comprises at least one inflection point comprising a minimum-sized discrete depression and at least one line of the second set comprises at least one inflection point comprising a maximum-sized discrete depression, wherein the minimum-sized discrete depression of the line of the first set is at a corresponding position within its line as is the maximum-sized discrete depression of the line of the second set. 
     
     
         14 . The sanitary tissue product according to  claim 1  wherein the first set of lines are equally distanced from the rhombus element's vertices in the rhombus element's smaller dimension. 
     
     
         15 . The sanitary tissue product according to  claim 1  wherein the rhombus element comprises an inner rhombus element having a larger dimension and smaller dimension that are different from the rhombus element's larger and smaller dimensions. 
     
     
         16 . The sanitary tissue product according to  claim 15  wherein the inner rhombus element exhibits a larger dimension and smaller dimension such that the inner rhombus element exhibits an aspect ratio of greater than 1.25. 
     
     
         17 . The sanitary tissue product according to  claim 15  wherein the inner rhombus element's larger dimension is parallel to the rhombus element's larger dimension. 
     
     
         18 . The sanitary tissue product according to  claim 1  wherein the discrete depressions are embossments. 
     
     
         19 . The sanitary tissue product according to  claim 1  wherein the discrete depressions are wet formed. 
     
     
         20 . The sanitary tissue product according to  claim 1  wherein the sanitary tissue product is a paper towel.
