PURPOSE:To reduce the exfoliating force applied to a sealing section by providing an unstuck section which regulates the opening margin of a mouth piece section to the mouth piece section. CONSTITUTION:A mouth piece member 2 tapered toward the center of a toner container main body 1 is provided on the bottom of the main body 1. The member 2 is formed by molding, for example, polystyrene and an adhesive section 8 for sticking a sealing film is provided on the surface of the member 2 facing the opening lid 3 of the container main body 1 so as to surround the opening 5 of the container main body 1. The projecting section of the member 2 formed of the tapered projecting member is set as an unstuck section 9 and projects toward the inside of the opening 5 from the sticking section 8 so as to regulate the opening edge of the opening 5. Therefore, even when a toner cartridge is dropped into the container main body 1, the dropping impact of the toner to the sealing edge section of the sealing film is not applied perpendicularly to the film and the exfoliating force applied to the sealing section is reduced. |
