Integral Dual Functionality Cleaning Pads

Abstract

A cleaning pad has a facing layer joined to a backsheet, and an absorbent core disposed between the facing layer and backsheet. The facing layer is an integral sheet having a first region comprising a plurality of apertures, and a second region comprising a plurality of raised protrusions. The two different regions provide dual functionalities of absorbing (or distributing) liquid, such as a cleaner, and scrubbing, respectively.

1 . A cleaning pad for attachment to the head of a cleaning implement, said pad comprising:
 a backsheet and a facing sheet joined in face-to-face relationship with an absorbent core therebetween, said facing sheet being an integral sheet having a first region having apertures therethrough, and a second region having a plurality of protrusions extending outwardly therefrom and away from said core.   
     
     
         2 . A cleaning pad according to  claim 1  wherein said cleaning pad is generally rectangularly shaped having two spaced longer edges and two spaced apart shorter edges, each of said backsheet and said facing sheet having two spaced apart longer edges and two spaced apart shorter edges, said longer edges of said backsheet extending outwardly beyond said longer edges of said facing sheet. 
     
     
         3 . A cleaning pad according to  claim 2  having a border between said first region and said second region, wherein said border between said first region and said contiguous second regions is substantially straight. 
     
     
         4 . A cleaning pad according to  claim 3 , having said first region intermediate two second regions, wherein one of each said second regions is juxtaposed with each said longer edge. 
     
     
         5 . A cleaning pad according to  claim 4  having a width between said longer edges, and said first region comprises from 30 to 90 percent of said width. 
     
     
         6 . A cleaning pad according to  claim 5 , wherein said first region and said second regions are contiguous. 
     
     
         7 . A cleaning pad according to  claim 5 , wherein said first region has apertures with an open area ranging from about 1 to about 9 square millimeters per aperture. 
     
     
         8 . A cleaning pad according to  claim 7 , wherein said second region has protrusions extending outwardly about 0.5 to about 4 millimeters. 
     
     
         9 . A cleaning pad according to  claim 1  wherein said first region and said second region overlap. 
     
     
         10 . A cleaning pad according to  claim 9  wherein said first region substantially circumscribes said second region. 
     
     
         11 . A cleaning pad according to  claim 1  wherein said first region and said second region are separated by a visually discernable region free of said plurality of protrusions and free of said apertures. 
     
     
         12 . A cleaning pad according to  claim 11  wherein said second region substantially circumscribes said first region. 
     
     
         13 . A cleaning pad according to  claim 1  removably attached to a cleaning implement, said implement comprising a handle and a head attached thereto, wherein said backsheet of said cleaning pad is attached to said head. 
     
     
         14 . A cleaning pad according to  claim 13  which is premoistened.
