PROBLEM TO BE SOLVED: To provide a seal for sealing constituted so that it can be easily peeled off by drawing out the extension piece of a sealing tape and a toner case can be easily opened without exerting an effect on the cutting and opening action of the sealing tape even in the case that the toner left at the upper part of the sealing tape is wound in when the toner case is opened. SOLUTION: The sealing tape 4 closing an opening port 3 is made to adhere to the upper surface of a substrate 2 so that is can be peeled off. Then, this seal for sealing is constituted so that the aperture of the toner case is closed by using the substrate 2 through adhesive agent applied to the lower surface of the substrate 2 by peeling a peeling paper 5 made to adhere to the lower surface of the substrate 2. Besides, two longitudinal-direction cut-off lines 8 for opening the surface of the tape 4 by drawing the extension piece 7 formed at one end of the tape 4 in a returning direction and a width-direction cut-off line 9 linked with the two lines 8 near a terminating end where the tape 4 is opened are formed in the tape 4. |
