Abstract
A pull-tab for a liquid container according to the present invention is designed in form of a sheet, and by providing a cutting line in form of a ring, leaving a connecting sector on the periphery, it comprises a handle sector, being the portion outside said cutting line, and a main sector, being the portion inside the cutting line. By providing another cutting line in convex arc in the direction away from the connecting sector on the main sector, a fastening sector is formed. In this pull-tab, the main sector covers the pouring mouth when the connecting sector is positioned near outer periphery of the pouring mouth of the liquid container. A sector between an end of the main sector opposite to the connecting sector and a fastening sector is bonded to the surface of the liquid container. When the handle sector is lifted up and the main sector is pulled up with edges of the bonded sector as a supporting axis, the fastening sector is turned, and its forward end is stopped on the surface of the liquid container.
