Embodiment Construction

[0071] Embodiments of the present invention will be described below with reference to the drawings.

[0072] figure 1 It is a schematic upper perspective view of the toner cartridge 10 of the present invention. The toner cartridge 10 is a container for storing fine powdery toner used in an image forming apparatus (not shown) such as a copier or a laser printer. In the toner cartridge 10, the casing 11 is covered with a cover 12, and after the cover 12 is fastened to the casing 11 by screws 13, the double-sided surface is pasted on the overlapping portion (gap) 14 formed by overlapping the casing 11 and the cover 12. Tape (sealing material) 15 to seal.

[0073] figure 2 It is a schematic upper perspective view of the toner cartridge 10 in a state where the casing 11 and the cover 12 are separated. The case 11 and the cover 12 of this embodiment are made of resin, but other materials may be used.

Abstract

Provided is a toner cartridge which can prevent leakage of toner by sealing a gap which appears when a lid is superimposed over a housing certainly, and also provided is a method for recycling same. A toner cartridge (10) attached to an image formation apparatus and supplying toner thereto comprises a housing (11) equipped with a section (16) for containing toner, and a lid (12) covering the section (16) for containing toner of the housing (11), wherein the first adhesive (31) of sealant (15) which is provided, on the opposite sides of a substrate (32), with the adhesive (31, 33) is stuck to the outer circumferential surface at a portion (14) where the lid (12) is superimposed over the housing (11), and a release paper (34) is stuck to the second adhesive (33) thus sealing the superimposed portion (14).

Description

technical field [0001] The present invention relates to a toner cartridge for an image forming apparatus such as a full-color copier or a printer, and more particularly to a toner cartridge that prevents toner leakage by a simple method during recycling. Background technique [0002] In the toner cartridge used in the conventional image forming apparatus, when there is a gap between the casing and the cover, the periphery of the developing part may be contaminated by toner ejection, etc., which is not preferable for image formation, so there is no The case and the cover are hermetically sealed by welding or the like. [0003] However, in the above-mentioned technique, when the cover is opened, unevenness occurs in the joining portion, so that welding work cannot be performed again, and there is a problem that recycling cannot be performed. [0004] In addition, when the toner cartridge is sealed with a tape without performing welding work, when the tape is peeled off at the...
