Patent number: 5190643Abstract: A lid assembly for a portable water treatment device of the type including a vessel with an opened upper end and a replaceable filter cartridge adapted to be contained therein. A lid assembly is adapted to be attached to the opened upper end of the vessel above the replaceable filter cartridge and operable to monitor the number of times the water treatment device is used. The lid assembly includes a housing having a central aperture therethrough communicating with the filter cartridge. A gate member is reciprocally movable between a position closing the aperture in the housing and a position opening the aperture in the housing. In the opened position, water to be treated may be poured into the filter cartridge through the aperture. Indicator means are provided and are movable incrementally in response to movement of the gate member. The indicator means move one increment during a cyclic movement of the gate member from the closed position to the opened position and back to the closed position.Type: GrantFiled: January 10, 1992Date of Patent: March 2, 1993Assignee: Mr. Coffee, Inc.Inventors: J.
