Abstract

The wiping device of the present invention comprises a thermoplastic sheet coupled with an optional absorbent core and an optional liquid impervious backsheet. The thermoplastic sheet defines a plurality of cavities including outwardly extending capillaries. Contained within the absorbent core for release upon demand is one or more fluids which facilitate and enhance the cleaning provided by the wiping device. As the cavities of the thermoplastic sheet are contacted with and wiped across a surface to be cleansed, the cavities collect and remove undesired material such as dirt, feces or blood. The selective release of the one or more fluids onto the surface to be cleansed further facilitates the cleaning and/or provides fragrance and/or medicaments, or the like, to the surface to be cleansed.
