Abstract
A top hinge is provided for a refrigerator cabinet door. A hinge body is formed of plastic having a top surface and a bottom surface. A hinge pin extends substantially perpendicularly from the bottom surface of the hinge body. One or more points of attachment are formed on the hinge body. An axis of twist passes through a center of the hinge pin and an effective center of attachment. At least a first rib and a second rib extend from the bottom surface of the hinge body. The ribs extend along a length of the bottom surface at an oblique angle relative to the axis of twist and diverge from each other by an angle of at least about 60 degrees.
