Abstract
A filter box for filtering trash from sand is disclosed. The box features a rectangular portion and a trapezoidal portion. The trapezoidal portion is enclosed by tapered sidewalls and an overlying trapezoidal top wall to form a funnel. The rectangular portion has upwardly projecting sidewalls which connect with the tapered sidewalls. A screen is fitted within the sidewalls of the rectangular portion and is utilized to filter, from sand, any trash that may be present. The filtered sand is then replaced into the receptacle from which it came by pouring it through the formed funnel of the filter box of this invention.
