Patent attributes
The present disclosure is directed to a strainer cartridge that may be inserted into a drain of a drain system. The strainer cartridge includes an upper strainer portion and a lower strainer portion that are telescopically engaged with each other such that the upper strainer portion is moved into and out of the lower strainer portion telescopically. The strainer cartridge has a compressed position in which a drain opening of the drain is sealed off such that fluid collects within a fluid basin in fluid communication with the drain, and the strainer cartridge has an expanded position in which fluid may flow through the drain opening and the upper and lower strainer portions. When in the compressed position, the lower strainer portion is telescopically inset within the lower strainer portion, and, when in the expanded position, the upper strainer portion extends outward from the lower strainer portion.
