Claims

[Scope of utility model registration request]

An opening extending in the longitudinal direction and having a frame-shaped adhesive surface around the periphery is provided on one side of a hollow container whose internal dimension in the longitudinal direction is larger than the internal dimension in the cross section, and at least the adhesive surface is provided in this opening. In a toner cartridge which is coated and sealed with a sealing member extending from the end of the unsealing end and folded back at the end of the unsealing start, the planar projection shape of the adhesive surface at the unsealing start end is formed into a comb-teeth shape, and the adhesive surface The toner cartridge is formed such that it protrudes from a neighboring portion, and the unit adhesion area of the sealing member in the opening direction of the sealing member gradually increases and decreases at the beginning of opening and at the end of opening, respectively. .
