REINFORCED SEALING OF DOSING BLADE ASSEMBLY AND PRINTER CARTRIDGE WITH SUCH SEALING Russian patent published in 2014 - IPC G03G15/08 

FIELD: printing.

SUBSTANCE: present invention generally relates to an image forming device, and more particularly, to a reinforced sealing of the dosing blade assembly and a cartridge for printer comprising such sealing. The claimed group of inventions comprises the reinforced sealing of the dosing blade assembly, as well as the cartridge for printer, which uses the above mentioned sealing of the assembly. The reinforced sealing of the dosing blade assembly comprises a main strip of flexible polymer film having the thickness, a surface of the predetermined area limited by parallel edges, and a folding zone extending along the length of the main strip between one pair of parallel edges and located between the other pair of parallel edges at a distance from them. The sealing also comprises an additional strip of flexible polymer film. The additional strip is applied to the main strip with a shift along one side of the folding zone on the main strip, so that the main strip has laminar and nonlaminar parts located near it, extending along the opposite sides of the folding zone, at that thickness of the laminar part is greater than thickness of the nonlaminar part. The sealing has a connection means in the form of the adhesive layer on the nonlaminar part of the main strip. The sealing is used in the cartridge of the printer.

EFFECT: technical result achieved from implementation of the claimed group of inventions is to provide the effective sealing between the dosing blade assembly and the housing of the cartridge of the printer.
