  • Publication number: 20110189060
    Abstract: The invention is an improvement to a multi-dosing detergent delivery device, the device being of a type comprising a housing (2) for receiving therein, in use, a cartridge (200) having a plurality X of chambers (210) each accommodating a detergent composition, a directing means (3, 34) to direct, in use, wash liquor selectively into a selected chamber (210) of the cartridge (200) to contact the detergent composition therein, an outlet to allow the detergent loaded wash liquor to exit the device and indexing means (100) for automatic movement of said cartridge (200) in use relative to said directing means (3, 34). The specific improvement to the device comprises a shutter mechanism (310, 320, 330) for blocking or obstructing passage of water/wash liquor from said directing means (3, 34) to the selected chamber (210) during part of a wash cycle so as to avoid a problem of detergent held within the chamber (210) from being washed out or diluted during a pre-wash cycle of a dishwasher.
