ABSTRACT:
A lightweight, disposable absorbent mat is adapted for placement beneath a motor vehicle or machine to catch oil, grease and other drippings and comprises a generally rectangular base layer which is made up of an oil-impervious material, and a plurality of upper, oil-absorbent plies are interconnected to one another and superimposed on the base layer, the plies being made up of a highly absorbent paper or cellulose material. The plies of paper material are interconnected at spaced intervals and may be covered with an upper plastic layer which is perforated to permit any drippings to pass through the upper layer into the absorbent plies, the upper layer having an outer peripheral edge or edges sealed to the outer peripheral edges of the bottom layer to form a moisture barrier around the sides of the absorbent plies; and stiffener frame members may be interposed between the outer peripheral edges of the upper and base layers.
