    摘要： A non-vent type fully openable easy-opening end has a principal score around the periphery of the end, and a pair of beads which run in a tearing direction. The pair of beads is formed symmetrically at both sides of a tab securing portion of the end which is in the vicinity of the tab securing score. A pair of second beads may also be formed on the periphery of a removable portion of the end which is defined by the principal score in such a manner that they run along the principal score. The second beads are located symmetrically on both sides of the tab securing portion. A straight line l that connects the forward end of the tab securing portion and the starting end of each of the first beads or the starting end of each of the second beads is inclined with respect to the tearing direction at an angle ranging between 45 degrees and 85 degrees. A distance a between the finishing ends of the first beads and the center of the tab securing portion in the tearing direction is equivalent to or larger than the diameter of the tab securing portion and is not less than 4 mm.
