Abstract:
1. A seal-assembly for sealing a toner passage in a toner hopper of a toner cartridge used in a dry toner style image forming apparatus, said seal-assembly including: a pull-strip; and a seal-insert including a substantially stiff layer sandwiched by a top and a bottom adherent layer whereby said seal-insert includes an open region; and a bottom release liner adhered under said bottom adherent layer used to protect said bottom adherent layer prior to installation of said seal-assembly; and a layer-to-be-torn adhered over said top adherent layer of said seal-insert which covers said open region; and a connecting region proximately located where said pull-strip is attached to said layer-to-be-tom approximately over a right end of said seal-insert; and whereby pulling on said pull-strip at the using location will cause at least one tear in said layer-to-be-tom, thus releasing a strip over a tear region of said layer-to-be-torn and thereby creating an opening in said layer-to-be-torn and thus allowing a powdered toner to pass through said opening in said layer-to-be-torn and thus allowing the powdered toner to pass through said open region of said seal-insert and thus allowing the powdered toner to pass through the toner passage in the toner hopper.
