ABSTRACT:
The present invention provides a colander serving bowl having an outer shell with an open bottom, a movable sealing plate with upwardly extending support arms that ride on inclined surfaces on the rim of the outer shell, and a perforated inner shell supported on the sealing place. The sealing plate is movable between a lowered sealing position where the plate seals the open bottom of the outer shell, and a raised draining position where the plate is spaced above the open bottom to allow draining through the open bottom. As the support arms are moved, the support surfaces of the arms move from the lower end to the upper end of the inclined surfaces of the rim, thus moving the sealing plate from the sealing position to the draining position.
