Abstract
A strainer structure for sinks and the like which minimizes clogging. The wall of the strainer which engages the material to be strained is formed with channels opening inwardly of the draining space. The opposed sides of each channel are apertured to permit passage of liquid therethrough to minimize clogging of the apertures by the material to be strained. The structure is applicable to planar and curved walls.
