ABSTRACT:
An absorbent pad for use in absorbing motor fluids, especially for use in absorbing and collecting motor fluids leaking from a motor/engine. The absorbent pad comprises a bottom liquid impermeable support layer, a layer of absorbent material and a top liquid permeable layer, wherein a portion of the top liquid permeable layer is bonded to a portion of the bottom liquid impermeable support layer with an adhesive strip thereby enclosing the absorbent material layer. In a preferred embodiment, the absorbent pad is prepared by a method comprising a step of forming at least one fold configuration selected from the group consisting of (A), (B) and (C) at a side of the absorbent pad, wherein: fold configuration (A) is formed by binding a portion of a bottom surface of the liquid permeable layer and a portion of a top surface of the liquid impermeable support layer with an adhesive strip; fold configuration (B) is formed by folding the liquid impermeable support layer around a side of the absorbent material layer and binding a portion of a top surface of the liquid impermeable support layer with an adhesive strip to a portion of a top surface of the liquid permeable layer; and fold configuration (C) is formed by partially draping the liquid permeable layer over the side of the absorbent layer, and binding a portion of the top surface of the liquid permeable layer with an adhesive strip to a portion of the top surface of the liquid impermeable support layer, wherein a midpoint of said adhesive strip is at a position along the side of the absorbent pad of at least 1/10ththe total distance from bottom to top of the pad as measured in a thickness direction T.
