  • Toner cartridge with rotator and sliding cover for toner leakage reduction
    Patent number: 8306463
    Abstract: A toner cartridge includes a housing having a first mouth and a second mouth, a rotator having a first opening and a second opening and being rotatably mounted on the housing in such a manner that the first and second mouths are accessible through the first and second openings respectively, and a sliding cover having a through hole and being slidably disposed on the housing in such a manner that the second mouth is closeable by the sliding cover. When the rotator is erroneously forced to rotate relative to the housing, the first mouth of the housing exposes outside through the first opening of the rotator and the second mouth of the housing will be covered by the sliding cover. Therefore, the leakage of the toner caused by a user's erroneous operation of the toner cartridge of the present invention can be effectively reduced.
