Abstract:
1. A multi-dosing detergent delivery device comprising: a housing; a cartridge received within the housing, the cartridge having a plurality X of chambers each accommodating a detergent composition; a lid adapted for receiving, in use, water or wash liquor and directing it selectively into a chamber of the cartridge to contact the detergent composition therein; an outlet to allow the detergent composition loaded wash liquor to exit the detergent delivery device; an automatic indexing mechanism for automatic movement of said cartridge relative to said lid when in use so as to cause a neighbouring chamber to be in an exposed, ready to be used, position prior to a next washing cycle; and an end stop mechanism which comprises a first end stop member that is associated with said lid and a second end stop member associated with rotational movement of said cartridge and wherein said second end stop member comprises a projection formed at the top of a shaft member that rotates with said cartridge, wherein said end stop mechanism is adapted to prevent actuation of said automatic indexing mechanism subsequent to an Xth washing cycle, wherein following the completion of a heating cycle of said Xth washing cycle, said end stop mechanism is actuated to prevent completion of a full indexing movement of said cartridge relative to said lid, wherein said indexing mechanism operates so as to impart a first amount of rotational movement to said cartridge during a heating cycle and to provide a second amount of rotational movement to said cartridge during a cooling cycle and said end stop mechanism is arranged to block completion of the second amount of rotational movement following the Xth heating cycle.
