Absorbent articles with elastomeric laminates

Abstract

An absorbent article includes a topsheet, backsheet and absorbent core disposed between a portion of the topsheet and the backsheet, and an elastomeric laminate. The elastomeric laminate includes a first nonwoven, a second nonwoven, and a preactivated film positioned between the first and second nonwoven; and a plurality of ultrasonic bonds. The absorbent core comprises absorbent material and at least one channel, wherein the at least one channel is substantially free of absorbent material.

 a plurality of ultrasonic bonds; and 
   wherein the absorbent core comprises absorbent material and at least one channel, wherein the at least one channel is substantially free of absorbent material.   
     
     
         2 . The absorbent article of  claim 1  wherein the first nonwoven comprises a spunbond layer. 
     
     
         3 . The absorbent article of  claim 2  wherein the first nonwoven comprises a SMS configuration. 
     
     
         4 . The absorbent article of  claim 1  wherein the absorbent material comprises superabsorbent polymers and comminuted wood pulp. 
     
     
         5 . The absorbent article of  claim 1  wherein the at least one channel is curvilinear. 
     
     
         6 . The absorbent article of  claim 1  wherein the absorbent core comprises two channels symmetrically disposed about a longitudinal axis of the article. 
     
     
         7 . The absorbent article of  claim 1  wherein the elastomeric laminate comprises an Air Permeability Value of at least about 1 m 3 /m 2 /min. 
     
     
         8 . The absorbent article of  claim 1  wherein the elastomeric laminate comprises an Average Peak Force at Break of 26 N or greater. 
     
     
         9 . The absorbent article of  claim 1  wherein the elastomeric laminate comprises an elastic region that is from about 30% to about 80% of a maximum width of the laminate. 
     
     
         10 . The absorbent article of  claim 1  wherein the elastomeric laminate further comprise one or more inelastic regions. 
     
     
         11 . The absorbent article of  claim 1  wherein the elastomeric laminate is a gathered laminate. 
     
     
         12 . The absorbent article of  claim 1  wherein the elastomeric laminate is disposed in an ear, wherein the ear is disposed in a rear waist region. 
     
     
         13 . The absorbent article of  claim 12  further comprising a fastening system, wherein the fastening system is joined to the elastomeric laminate in an elastic region of the elastomeric laminate. 
     
     
         14 . The absorbent article of  claim 1  wherein the preactivated film comprises a styrenic block copolymer film. 
     
     
         15 . The absorbent article of  claim 1  wherein the preactivated film comprise a basis weight from about 10 to about 100 gsm. 
     
     
         16 . An absorbent article comprising:
 a topsheet, backsheet and absorbent core disposed between a portion of the topsheet and the backsheet, and   an ear comprising an elastomeric laminate, the elastomeric laminate being a gathered laminate and comprising:
 a first nonwoven, a second nonwoven, and a preactivated film positioned between the first and second nonwoven; and 
 a plurality of ultrasonic bonds. 
   
     
     
         17 . The absorbent article of  claim 16  wherein the first nonwoven comprises a SMS configuration. 
     
     
         18 . The absorbent article of  claim 16  wherein the elastomeric laminate comprises an Air Permeability Value of at least about 1 m 3 /m 2 /min. 
     
     
         19 . The absorbent article of  claim 16  wherein the elastomeric laminate comprises an Average Peak Force at Break of 26 N or greater. 
     
     
         20 . The absorbent article of  claim 16  wherein the elastomeric laminate comprises an elastic region that is from about 30% to about 80% of a maximum width of the laminate. 
     
     
         21 . The absorbent article of  claim 20  wherein the elastomeric laminate further comprise one or more inelastic regions. 
     
     
         22 . The absorbent article of  claim 20  wherein the further comprising a fastening system, wherein the fastening system is joined to the elastomeric laminate in an elastic region of the elastomeric laminate. 
     
     
         23 . The absorbent article of  claim 16  wherein the preactivated film comprises a styrenic block copolymer film. 
     
     
         24 . The absorbent article of  claim 16  wherein the preactivated film comprise a basis weight from about 10 to about 100 gsm.
