At least some land areas of the plurality of land areas surround at least some apertures of the plurality of apertures. The patterned apertured web has an Effective Open Area in the range of about 3% to about 30%, according to the Aperture Test herein. The patterned apertured web has a plurality of Interaperture Distances, according to the Aperture Test herein. The Interaperture Distances have a distribution having a median and a mean.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A patterned apertured web comprising:

         2 . The patterned apertured web of  claim 1 , wherein the patterned apertured web comprises at least two layers, and wherein the at least two layers comprise a first spunbond layer and a second spunbond layer. 
     
     
         3 . The patterned apertured web of  claim 2 , wherein the first layer has a first basis weight, wherein the second layer has a second basis weight, and wherein the first basis weight is substantially the same as the second basis weight. 
     
     
         4 . The patterned apertured web of  claim 2 , wherein the first layer has a first basis weight, wherein the second layer has a second basis weight, and wherein the first basis weight is different than the second basis weight. 
     
     
         5 . The patterned apertured web of  claim 2 , comprising a third layer. 
     
     
         6 . The patterned apertured web of  claim 2 , comprising a third spunbond layer. 
     
     
         7 . A diaper comprising:
 a) the patterned apertured web of  claim 1 ;   b) a backsheet;   c) an absorbent core positioned at least partially intermediate the patterned apertured web and the backsheet; and   d) a pair of leg cuffs.   
     
     
         8 . The patterned apertured web of  claim 1 , wherein at least some apertures of the plurality of apertures form a second enclosed shape. 
     
     
         9 . The patterned apertured web of  claim 8 , wherein the second enclosed shape at least partially surrounds the enclosed shape. 
     
     
         10 . The patterned apertured web of  claim 1 , wherein the perimeter of the enclosed shape defines a point where the concavity ends. 
     
     
         11 . The patterned apertured web of  claim 1 , wherein the second layer has a different hydrophobicity than the first layer. 
     
     
         12 . A patterned apertured web comprising:
 a plurality of land areas in the patterned apertured web; and   a plurality of apertures defined in the patterned apertured web, wherein at least some land areas of the plurality of land areas surround at least some apertures of the plurality of apertures;   wherein the plurality of apertures are non-homogeneous in a repeat unit such that at least two apertures of the plurality of apertures have a different size, a different shape, or a different Absolute Feret Angle, according to an Aperture Test;   wherein the patterned apertured web has an Effective Open Area in a range of about 3% to about 15%, according to the Aperture Test;   wherein the patterned apertured web comprises spunbond fibers comprising polypropylene;   wherein the patterned apertured web comprises a portion of a topsheet; and   wherein at least some apertures of the plurality of apertures form a first enclosed shape, and wherein at least some apertures of the plurality of apertures form a second enclosed shape.   
     
     
         13 . The patterned apertured web of  claim 12 , comprising at least two layers, wherein the at least two layers comprise a first spunbond layer and a second spunbond layer. 
     
     
         14 . The patterned apertured web of  claim 13 , comprising a third spunbond layer. 
     
     
         15 . The patterned apertured web of  claim 12 , wherein the first enclosed shape is a heart shape comprising at least six apertures of the plurality of apertures. 
     
     
         16 . The patterned apertured web of  claim 15 , wherein the second enclosed shape is a diamond. 
     
     
         17 . The patterned apertured web of  claim 16 , wherein the first enclosed shape is positioned at least partially within the second enclosed shape. 
     
     
         18 . The patterned apertured web of  claim 13 , wherein the second spunbond layer has a different hydrophobicity than the first spunbond layer. 
     
     
         19 . A patterned apertured web comprising:
 a plurality of land areas in the patterned apertured web; and   a plurality of apertures defined in the patterned apertured web, wherein at least some land areas of the plurality of land areas surround at least some apertures of the plurality of apertures;   wherein the plurality of apertures are non-homogeneous in a repeat unit such that at least two apertures of the plurality of apertures have a different size or a different shape;   wherein the patterned apertured web has an Effective Open Area in the range of about 10% to about 40%, according to an Aperture Test;   a first spunbond layer;   a second spunbond layer;   a third spunbond layer;   wherein the spunbond layers comprise polypropylene; and   wherein at least some apertures of the plurality of apertures form a heart shape.   
     
     
         20 . The patterned apertured web of  claim 19 , wherein at least some apertures of the plurality of apertures form a heart shape, wherein at least some apertures of the plurality of apertures form a diamond shape, wherein the heart shape is positioned within the diamond shape, and wherein at least some apertures of the plurality of apertures have an Effective Aperture Area in a range of about 0.5 mm 2  to about 8.0 mm 2 , according to the Aperture Test.
