With the rapid development of economy in China and the acceleration of people's living pace, Chinese fast food came into a new stage of fast development. However, the western fast food holds most part of the market, and the situation about the development of Chinese fast food becomes even worse. Especially the tableware of Chinese fast food in present market, which can't embody the characteristic of Chinese fast food, has a bad influence on the development of Chinese fast food. Therefore, this paper proposes a new research direction of the fast-food tableware design which based on semiotics, and use the semantic difference chart to designate the direction in prophase of the design. Hope to find a scientific and reasonable method and flow for not only fast-food tableware design but also other products design.
