Abstract
In one example, a pitcher is provided that includes a chassis in which an untreated water reservoir is received. The untreated water reservoir has a candle that defines a receptacle with a fluid inlet and a fluid outlet, where the fluid outlet is arranged for fluid communication with the treated water reservoir, and the receptacle is configured to receive a filter cartridge. The candle also includes a filter seat that cooperates with the filter cartridge to form a substantially fluid-tight seal when the filter cartridge is positioned in a sealing range defined by the candle. The pitcher also includes a structural element that is connected to a portion of the pitcher and has a protruding portion that is located near the filter cartridge when the filter cartridge resides in the sealing range.
