Abstract
A pull-tab (10) for a pour opening in a surface of a lid is provided in the form of a sheet having a peripheral portion cut (17) into a ring shape with a connecting portion (15) remaining uncut so that a tab portion (20) and a body portion (30) are defined outside and inside the cut, respectively. The body portion (30) has an end portion remote from the connecting portion (15) and folded toward the back side thereof along a folding line (33) extending obliquely at an angle of 45 degrees with respect to a line connecting the end portion and the connecting portion. The pull-tab (10) is placed on the pour opening (83) and the lower side of the folded portion (31) is bonded to a surface of the upper lid (81) such that the pour opening (83) is covered with that portion of the body portion (30) located between the folded fixing part (31) and the connecting portion (15).
