  • Publication number: 20180171611
    Abstract: A descending spiral sink drain hole insert is comprised of a ring, an attached descending, circular spiral, and preferably (but not necessarily) a metallic material. This ring sits flush against a sink surface, suspending the spiral inside of a sink drain hole, where it allows waste and water to drain downward, yet shields any splattering debris from resurging when a garbage disposal unit is operated. The preferably metallic material would be ideal for easy-cleaning, sturdy quality, dirt-resistance, and easy handling.
