Multi-Dosing Detergent Delivery Device
First Claim
1. A multi-dosing detergent delivery device, the device comprising a housing and 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 and an outlet to allow the detergent loaded wash liquor to exit the device, automatic indexing means 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 for preventing 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, end stop means are 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.

Abstract
The invention relates to a multi-dosing detergent delivery device. In embodiments of the present invention, the device comprises a housing (2) for receiving a cartridge (200). The cartridge (200) has a plurality X of chambers, each accommodating a detergent composition. The device has a lid (3,1100) for receiving water/wash liquor and directing it selectively into a chamber of the cartridge (200) to contact the detergent composition therein and an outlet to allow the detergent loaded wash liquor to exit the device. The device has automatic indexing means (100) for automatic movement of said cartridge (200) relative to said lid (3,1100) so as to cause a neighbouring chamber to be in an exposed, ready to be used, position prior to a next washing cycle and features an end stop mechanism (A,B) for preventing actuation of said automatic indexing mechanism (100) subsequent to an Xth washing cycle. The indexing mechanism (100) operates so as to impart a first amount of rotational movement to said cartridge (200) during a heating cycle and to provide a second amount of rotational movement to said cartridge (200) during a cooling cycle and said end stop mechanism (A,B) is arranged to block completion of the second amount of rotational movement following the Xth heating cycle.
