Abstract In order to forecast the development direction of dispensing system to adapt the need of nonce packaging, the technology evolution pattern of TRIZ and subsystem of technology system was combined, and a table of subsystem and technological evolution pattern was built. Based on the character of dispenser subsystem structure, the evolution rule of the subsystems of dispensing system was analyzed along evolutional routes of different evolution patterns by the place in the table. The place on the evolution routes for dispenser subsystem was determined, and the possible development direction of dispensing system was obtained by the present place．
