PROBLEM TO BE SOLVED: To provide a carton which is provided with a large opening part in an upper face plate and excellent in sealing stability by providing a first connection part parallel to the unsealing direction of a take-out flat on the position close to an unsealing start piece above a fold of an opening line. SOLUTION: A first connection part 27 is provided on an opening line OL on both sides of an unsealing start piece 26. The connection part 27 is provided on a discontinuous part, and is separated in the vertical direction but agreed at the right and left positions. A second connection part 28 is not only same in constitution as the first connection part 27, but also discontinuous in the opening line OL. When the unsealing start piece 26 is picked and lifted, the first connection part 27 is broken to form a take-out flap and make an opening. A cutting line CL to receive the unsealing start piece 26 is provided opposite thereto on a fold L5. After the unsealing, the unsealing start piece 26 is inserted in the cutting line CL to enable the re-closing.
