Embossed absorbent systems and absorbent articles including the same

Abstract

An absorbent system including an absorbent core with at least one material free zone, at least one central longitudinal extending deep embossed channel, and at least two longitudinal extending deep embossed channels positioned between the material free zone and lateral edges of the absorbent system.

We claim: 
     
         1 . An absorbent system comprising:
 an absorbent core comprising at least one material free zone;   at least one central longitudinal extending embossed channel; and   at least two longitudinal extending embossed channels positioned between the at least one material free zone and lateral edges of the absorbent system.   
     
     
         2 . The absorbent system of  claim 1 , wherein:
 the absorbent core comprises two material free zones and two central longitudinal extending embossed channels.   
     
     
         3 . The absorbent system according to  claim 2 , wherein the central embossed channels are sinusoidal in shape. 
     
     
         4 . The absorbent system according to  claim 3 , wherein the lateral embossed channels are made from a repeating pattern of triangle shaped embossments. 
     
     
         5 . The absorbent system according to  claim 4 , wherein the embossed channels are coextensive with a length of the absorbent system. 
     
     
         6 . The absorbent system according to  claim 2 , wherein the material free zones comprise an open area of from 5% to 15% of a total area of the absorbent core. 
     
     
         7 . The absorbent system according to  claim 2 , wherein the material free zones have a length that is 20% to 80% of a total length of the absorbent core. 
     
     
         8 . The absorbent system according to  claim 1 , further comprising a liquid management system below the absorbent core. 
     
     
         9 . The absorbent system according to  claim 8 , wherein a length of the liquid management system is greater than a length of the at least one material free zone. 
     
     
         10 . An absorbent product comprising:
 a backsheet;   a coversheet; and   an absorbent system disposed between an upper surface of the backsheet and a lower surface of the coversheet, the absorbent system comprising:
 an absorbent core comprising at least one material free zone; 
 at least one central longitudinal extending embossed channel; and 
 at least two longitudinal extending embossed channels positioned between the at least one material free zone and lateral edges of the absorbent system, 
   wherein a body facing surface of the backsheet includes elastic strands aligned to pass longitudinally in a central portion of the at least one material free zone.   
     
     
         11 . The absorbent product according to  claim 10 , further comprising a liquid management system disposed between an upper surface of the absorbent system and the lower surface of the coversheet.
