Abstract

The present invention provides a napkin assembly for a dispenser. The napkin assembly may include a first napkin sheet further including a plurality of napkins and a second napkin sheet further including a plurality of napkins. Each napkin of both sheets having a basis weight from about 20 gsm to about 40 gsm may be connected to an adjacent napkin in series by a plurality of tabs. The second napkin sheet may be positioned proximate to the first napkin sheet in an offset relation and the first and second napkin sheets may be formed into a nested configuration for dispensing.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . A napkin assembly for a dispenser, the napkin assembly comprising: 
 a first napkin sheet further comprising a plurality of napkins wherein each napkin has a basis weight from about 20 gsm to about 40 gsm and is connected to an adjacent napkin in series by a plurality of tabs;    a second napkin sheet further comprising a plurality of napkins wherein each napkin has a basis weight from about 20 gsm to about 40 gsm and is connected to an adjacent napkin in series by a plurality of tabs, the second napkin sheet being positioned proximate to the first napkin sheet in an offset relation so that the first and second napkin sheets are formed into a nested configuration for dispensing.    
     
     
         2 . The napkin assembly of    claim 1    wherein each napkin of the first and second napkin sheets further comprises a first member integrally formed with a second member forming a fold between the first and second members; and 
 at least one napkin from the first napkin sheet terminates at about the fold of a respective napkin from the second napkin sheet.  
 
     
     
         3 . The napkin assembly of    claim 2    wherein at least 500 napkins from the first napkin sheet terminate at about the fold of a respective napkin from the second napkin sheet.  
     
     
         4 . The napkin assembly of    claim 1    wherein the napkin basis weight is about 30 gsm.  
     
     
         5 . The napkin assembly of    claim 1    wherein the napkins comprise pulp fibers.  
     
     
         6 . The napkin assembly of    claim 1    wherein the machine direction tensile is greater than about 2000 g f .  
     
     
         7 . The napkin assembly of    claim 1    wherein the T/S ratio is greater than about 0.03.  
     
     
         8 . The napkin assembly of    claim 1    wherein the tab strength is greater than about 30 g f .  
     
     
         9 . A napkin assembly for a dispenser, the napkin assembly comprising: 
 a first napkin sheet further comprising a plurality of napkins wherein each napkin is connected to an adjacent napkin in series by a plurality of tabs;    a second napkin sheet further comprising a plurality of napkins wherein each napkin is connected to an adjacent napkin in series by a plurality of tabs;    each napkin of the first and second napkin sheets further includes a first member, a second member, and a third member wherein the first member is formed integrally with the second member forming a first fold between the first and second members and the second member is formed integrally with the third member forming a second fold between the second and third members; and    at least one napkin from the first napkin sheet terminates at about the second fold of a respective napkin from the second napkin sheet when nestably configured for dispensing.    
     
     
         10 . The napkin assembly of    claim 9    wherein at least 500 napkins from the first napkin sheet terminate at about the second fold of a respective napkin from the second napkin sheet.  
     
     
         11 . The napkin assembly of    claim 9    wherein the napkin basis weight is from about 20 gsm to about 40 gsm.  
     
     
         12 . The napkin assembly of    claim 11    wherein the napkin basis weight is about 30 gsm.  
     
     
         13 . The napkin assembly of    claim 9    wherein the napkins comprise pulp fibers.  
     
     
         14 . The napkin assembly of    claim 9    wherein the machine direction tensile is greater than about 2000 g f .  
     
     
         15 . The napkin assembly of    claim 9    wherein the T/S ratio is greater than about 0.03.  
     
     
         16 . The napkin assembly of    claim 9    wherein the tab strength is greater than about 30 g f .  
     
     
         17 . A napkin assembly for a dispenser, the napkin assembly comprising: 
 a first napkin sheet further comprising a plurality of napkins wherein each napkin is connected to an adjacent napkin in series by a plurality of tabs;    a second napkin sheet further comprising a plurality of napkins wherein each napkin is connected to an adjacent napkin in series by a plurality of tabs;    each napkin of the first and second napkin sheets further includes a first member, a second member, a third member, and a fourth member wherein the first member is formed integrally with the second member forming a first fold between the first and second members, the second member is formed integrally with the third member forming a second fold between the second and third members, and the third member is formed integrally with the fourth member forming a third fold between the third and fourth members;    the second and third members have a length about twice that of the first and fourth members; and    at least one napkin from the first napkin sheet terminates at about the middle of a third member of a respective napkin from the second napkin sheet when nestably configured for dispensing.    
     
     
         18 . The napkin assembly of    claim 17    wherein at least 500 napkins from the first napkin sheet terminate at about the middle of a third member of a respective napkin from the second napkin sheet.
