Surface treated paper product

Abstract

A soft tissue product includes a surface treatment composition disposed on a treated portion that extends to the edges of the product, but which leaves the corners of the product untreated. The shape of the treated portion effectively ensures consumer benefit while reducing the total amount of additive composition on the product by placing the treatment composition in the portion of the product that is most likely to come into contact with the skin of a user.

1 . A tissue product comprising a substrate defining a major surface having a rectangular planar surface area defining first and third opposed edges, second and fourth opposed edges, and first, second, third, and fourth corner portions, the tissue product further comprising a treated portion comprising an additive composition disposed on the major surface, wherein the treated portion intersects the first, second, third, and fourth edges of the major surface, and even further wherein the corner portions of the major surface are untreated.  
   
   
       2 . The tissue product of  claim 1 , wherein the treated portion has a substantially parallelogram shape, the treated portion being positioned on the major surface wherein the corners of the parallelogram-shaped treated portion substantially bisect the edges of the major surface.  
   
   
       3 . The tissue product of  claim 1 , wherein the treated portion has a substantially elliptical shape, the circumference of the elliptical-shaped treated portion substantially bisecting the edges of the major surface.  
   
   
       4 . The tissue product of  claim 1 , wherein the additive composition is applied at an add-on level of from about 0.01 to about 20 percent of the basis weight of the substrate.  
   
   
       5 . The tissue product of  claim 1 , wherein the treated portion comprises from about 100 to about 1,000,000 individual deposits of treatment composition per square inch of the planar surface area.  
   
   
       6 . The tissue product of  claim 1 , wherein the treated portion covers from about 50 to about 80 percent of the planar surface area.  
   
   
       7 . The tissue product of  claim 1 , wherein the treated portion is divided into two parts separated by an intervening untreated portion.  
   
   
       8 . The tissue product of  claim 7 , wherein the intervening untreated portion extends from the first edge of the major surface to the third edge.  
   
   
       9 . The tissue product of  claim 8 , wherein the two parts of the treated portion each extends from the first edge of the major surface to the third edge.  
   
   
       10 . The tissue product of  claim 8 , wherein the tissue product is folded along the intervening untreated portion.  
   
   
       11 . The tissue product of  claim 1 , wherein the additive composition comprises from about 30 to about 90 weight percent oil and from about 10 to about 40 weight percent wax, said composition having a melting point of from about 30° C. to about 70° C.  
   
   
       12 . The tissue product of  claim 11 , wherein the add-on level of the additive composition is from about 3 to about 15 weight percent of the basis weight of the substrate.  
   
   
       13 . The tissue product of  claim 11 , wherein the additive composition further comprises from about 5 to about 40 weight percent fatty alcohol.  
   
   
       14 . The tissue product of  claim 11 , wherein the amount of oil in the composition is from about 40 to about 70 weight percent.  
   
   
       15 . The tissue product of  claim 11 , wherein the amount of wax in the composition is from about 10 to about 30 weight percent.  
   
   
       16 . The tissue product of  claim 1 , wherein the additive composition comprises a silicone compound.  
   
   
       17 . The tissue product of  claim 16 , wherein the add-on level is from about 0.5 to about 3 weight percent of the basis weight of the substrate.  
   
   
       18 . A hand towel comprising the tissue product of  claim 1 .  
   
   
       19 . A facial tissue comprising the tissue product of  claim 1 .  
   
   
       20 . A multi-ply tissue product comprising first and second outer plies and an inner ply, wherein the outer plies comprise the tissue product of  claim 1 .  
   
   
       21 . A method of making a tissue product comprising the steps of: providing a tissue web and an additive composition; applying the additive composition to the tissue web; and recovering the tissue product of  claim 1 .  
   
   
       22 . A tissue product comprising a substrate defining a major surface having a rectangular planar surface area defining first and third opposed edges, second and fourth opposed edges, and first, second, third, and fourth corner portions, the tissue product further comprising a treated portion comprising an additive composition disposed on the major surface, wherein the treated portion extends from the first edge of the major surface to the third edge, further wherein the treated portion extends from the second edge of the major surface to the fourth edge, and even further wherein the corner portions of the major surface are untreated.  
   
   
       23 . A tissue product comprising a substrate defining a major surface having a rectangular planar surface area, the tissue product further comprising a treated portion comprising an additive composition disposed on the major surface, the treated portion having a substantially parallelogram shape, the treated portion being positioned on the major surface wherein the corners of the parallelogram-shaped treated portion substantially bisect the sides of the major surface.
