Abstract
A drain stopper and strainer for a kitchen sink has a cap, a cap seal, an open-close mechanism, a strainer connected to a lower end of the open-close mechanism with an easy-connect mechanism, and an annular seal engaged with the strainer that seals an annular space between the strainer and a drain fitting. The cap seal preferably seals against the strainer. The stopper/strainer can be pushed into and pulled out of the drain fitting without assembly or disassembly. The strainer can be easily disconnected for cleaning and can be easily reconnected afterwards. For a drain fitted with a garbage disposal unit, the strainer has a hub-and-spoke structure for preventing eating and cooking utensils from falling into the garbage disposal unit.
