Absorbent sheet products strip having limited liquid strike-through property

Abstract

An absorbent sheet products strip, the strip including a continuous succession of individual absorbent sheets separated from each other by tear lines. The absorbent sheets are made of at least two plies bonded together by bonding points or lines or curves forming pattern units. Multiple pattern units are distributed all over a surface of the individual absorbent sheets such that the pattern units of one individual absorbent sheet does not superpose with other pattern units of a determined number of successive individual absorbent sheets in the strip when said successive individual absorbent sheets are disposed on each other.

1 . An absorbent sheet products strip, the strip comprising a continuous succession of individual absorbent sheets separated from each other by tear lines, the absorbent sheets being made of at least two plies bonded together by bonding points or lines or curves forming pattern units, multiple pattern units being distributed all over a surface of the individual absorbent sheets,
 wherein the pattern units are distributed all over the surface of the individual absorbent sheets such that the pattern units of one individual absorbent sheet does not superpose with other pattern units of a determined number of successive individual absorbent sheets in the strip when said successive individual absorbent sheets are disposed on each other.

         3 . The absorbent sheet products strip of  claim 1 , wherein the determined number of successive individual absorbent sheets is three. 
     
     
         4 . The absorbent sheet products strip according to  claim 1 , wherein the determined number of successive individual absorbent sheets are disposed on each other by Z-folding. 
     
     
         5 . The absorbent sheet products strip according to  claim 1 , wherein the strip comprises a single pattern unit distributed over the surface of the individual absorbent sheets. 
     
     
         6 . The absorbent sheet products strip according to  claim 1 , wherein the strip comprises multiple pattern units distributed over the surface of the individual absorbent sheets. 
     
     
         7 . The absorbent sheet products strip according to  claim 6 , wherein each individual absorbent sheet is defined between two consecutive tear lines extending according to a cross-machine direction, each individual absorbent sheet being subdivided in a determined number of zones along a defined direction, and wherein the pattern unit has a size that does not exceed a zone size, the pattern unit being repeated every n zones, n being a pattern repeat, adjacent zones following the zone comprising the pattern unit being free of pattern unit, said repetition continuing over the determined number of successive individual absorbent sheets. 
     
     
         8 . The absorbent sheet products strip of  claim 7 , wherein the zones are columns extending according to the cross-machine direction and distributed along a machine direction. 
     
     
         9 . The absorbent sheet products strip of  claim 7 , wherein the strip comprises a single pattern unit distributed all over the surface of the individual absorbent sheets and the determined number of zones is odd. 
     
     
         10 . The absorbent sheet products strip according to  claim 7 , wherein the determined number of zones is seven, the pattern repeat n is four, and the determined number of successive individual absorbent sheets is three. 
     
     
         11 . The absorbent sheet products strip of  claim 7 , wherein the pattern units in the zones are stripes extending in an inclined manner relative to the cross-machine direction and distributed along a machine direction. 
     
     
         12 . The absorbent sheet products strip according to  claim 6 , wherein the pattern units are of different sizes such that the pattern units are homothetic and homocentric when superposed one over the other, wherein a size of the greatest pattern units do not exceed a zone size, each zone comprising one pattern unit according to the machine direction, and multiple pattern units according to the cross-machine direction. 
     
     
         13 . The absorbent sheet products strip according to  claim 6 , wherein the pattern units are arranged in such a manner to be imbricated in each other without superposing one over the other. 
     
     
         14 . The absorbent sheet products strip of  claim 12 , wherein the pattern units are ellipsis, circle, square, rectangle, or triangle. 
     
     
         15 . The absorbent sheet products strip according to  claim 7 , wherein all the zones have the same zone size. 
     
     
         16 . The absorbent sheet products strip according to  claim 7 , wherein the zones have variable zone size. 
     
     
         17 . A roll of wound material comprising the absorbent sheet products strip according to  claim 1 . 
     
     
         18 . A stack of folded material comprising the absorbent sheet products strip according to  claim 1 . 
     
     
         19 . A method comprising using the absorbent sheet products strip according to  claim 1  as a towel, kitchen towel, hand towel, toilet paper, wipe, or facial tissue.
