摘要：
A box-shaped container (10) has an opening (12) and the opening is sealed tightly and doubly by a sealing material (13). The sealing material is hot-glued to a peripheral portion of the opening of the cartridge body to such an extent that the sealing material can be peeled from the peripheral part. The end portion (13a) of the sealing material is bonded at an adequate length from the free end to the face 11a of a side of the peripheral portion, and the free end portion is turned down for 180 degree angle to the outer side of the opening. Furthermore, the sealing material is bonded to the face (11b) of a opposite side of the peripheral portion side at which the free end portion (13a) is adhered and turned down to cover the opening in double covering. The sealing material also covers the turned-down end portion. The other end portion (13b) of the sealing material is attached to a roller (16), and as the user turns a handle (18) of the roller, the sealing material can be peeled off easily.
