Multi-dosing detergent delivery device

Abstract

The invention relates to a multi-dosing detergent delivery device. In embodiments of the present invention, the device comprises a housing () for receiving a cartridge (). The cartridge () has a plurality X of chambers, each accommodating a detergent composition. The device has a lid () for receiving water/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. The device has automatic indexing means () for automatic movement of said cartridge () relative to said lid () so as to cause a neighboring 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 () subsequent to an Xth washing cycle. The 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 (A,B) is arranged to block completion of the second amount of rotational movement following the Xth heating cycle.
