Pop cans are general beverage packages for modern people. However, the drinking outlets of the cans may be polluted or get dirt during the processes of storage, transportation, and vender. Therefore, the new design employs a mask-ring-pull to solve the problems and ensure instant and clean tastes for the users. The mask-ring-pull is on the can side and extends to the can top. It not only provides sanitary sealing for the can rims but also links the top outlet for pull-opening. Moreover, after opened, the mask-ring-pull serves as a lid to cover the outlet for next time use.
