Abstract
A sink strainer with water flow channels that allow the strainer to drain water even when covered with food debris. Each water flow channel increases the water flow efficiency of the strainer by adding water entry places that are not found in traditional strainers. For instance, water is allowed to flow through the rim of the present sink strainer. Each water flow channel includes a perforated raised rim ridge that allows water to enter the strainer through the edge of the rim and through the top of the rim. Each water flow channel also includes a perforated lower tunnel that adds additional water entry places to the perforated cup of the stainer. The preferred embodiment of the present sink strainer includes four perforated water flow channels that are spaced equally around the strainer.
