In the present day marketing of the beer or soft drinks packaged in the cans, six cans are bound to one pack by a plastic sheet with six holes forcedly inserted around the top portion of the cans. Although said type of packaging is economic, it is less than completely sanitary. Most people drink the content in the can directly from the can without washing the can. In said packaging method of cans, the top of cans are completely exposed and often contaminated by dusts and other sources during the transportation, storage and display in the retail stores. As a consequence, the can tops are not clean for directly drinking from the can in said packaging method. The present invention discloses the method of incorporating a thin plastic sheet to said plastic packaging ring, which incorporation provides means for covering up the can tops.
