Abstract: The pull tab portion is formed as an area surrounded by four solid or broken line-formed incisions. The four incisions include a first incision which is formed as a boundary line of the push-in portion, a pair of second incisions each of which is continuous with the first incision and which are spaced apart from each other in the width direction of the adhesive tape, and a third incision which is continuous with each of the pair of second incisions and functions as a folding line. When those ends of the pair of second incisions which are each located opposite to the push-in portion are called tape-side incision ends, the distance between the two tape-side incision ends in the width direction of the adhesive tape is set greater than the width of the adhesive tape.
