The bottom portion has a downwardly bent peripheral edge portion. The barrel portion has an attached barrel overlap portion where both end edges of the blank are overlapped with each other and sealed, a lower fold-back portion which is formed at a lower end of the barrel portion by folding back the blank inwardly, and an upper fold-back portion which is formed by folding back the ends of the fold-back blank inwardly. The lower end of the barrel portion, the upper fold-back portion, and the peripheral edge portion of the bottom portion are sealed together. The peripheral edge portion is inserted into the lower fold-back portion.
