Abstract
This invention is an fluid absorbing means wherein an integral grid of inverted, semi-conical projections or fingers with rounded upper ends is provided. This grid can be walked on while preventing oil or other liquids which are dripped, spilled or otherwise deposited thereon from coming into contact with the soles of the user's shoes. Openings are provided at the juncture of the inverted, semi-conical fingers so that the contaminating fluid can pass therethrough onto an absorbing mat disposed thereto. This absorbing mat can be formed from cotton fiber, polymer material, polyethylene sponge, cellulose fiber or other suitable material or a combination thereof. A housing means completely surrounds the grid and its underlying absorbing material and includes an integral bottom to contain the contaminating fluids should the absorbing material become saturated. Wing-like curb markers can be attached to the housing if desired to act as a guide if the fluid absorbing system of the present invention is used in conjunction with parked vehicles.
