ABSTRACT:
A disposable drain strainer is removably received within a drain opening having an adjacent drain rim substrate. The strainer has a strainer portion, a ring portion, and a seal release mechanism. Top and bottom surfaces of the ring portion are adapted to sealingly engage the drain rim substrate. The seal release mechanism is integral with the ring portion, and facilitates release of the seal so that the strainer can be readily be removed from the sink and discarded. In one aspect, the seal release mechanism comprises a tab. In another aspect, the seal release mechanism comprises a press-release component, wherein the ring portion has arced ring walls having convex and concave configurations. During sealing engagement with the drain rim, the ring portion is in the convex configuration. Pressure applied to the ring portion causes it to move to the concave configuration. The seal between the ring portion and the substrate is released, and the strainer can be readily removed from the drain opening for disposal without having to touch the strainer contents.
