A blank (100) is provided with: a panel structure (101) provided with a top wall panel (110) in which neck holes (102) into which bottle neck parts are to be inserted are formed, and side wall panels (111, 112) connected to the top wall panel with panel connection seams (151, 161) interposed therebetween; and stop tabs (103) positioned on the inner side of the neck holes, the stop tabs being connected to the side wall panels with a tab connection seam (156) interposed therebetween, and having a free end (109) on the opposite side of the tab connection seam. The tab connection seam is located at a position offset from the panel connection seams toward the side wall panel so as to be set apart from and discontinuous with the panel connection seams, and is provided with a first fold line (157) positioned on one end side of the tab connection seam, a second fold line (158) positioned on the other end side of the tab connection seam, and a cut line (159) extending so as to span between the first fold line and the second fold line. The tab connection seam extends so as to curve or bend in a shape that is recessed toward the stop tab (103). |
