Angled seal for laser toner cartridge hopper
View Patent ↗A remanufactured laser printer toner cartridge having a foam gasket seal with the transverse edge of the inner periphery extending from a longitudinal edge at an acute angle, preferably about 22 degrees, which angled edge prevents post testing excess toner from building up into a roll and jamming at the exit port as the remanufactured cartridge's pull strip is pulled when making the cartridge ready to install into the printer, and minimizes the likelihood that the gasket will be pulled off of the cartridge hopper section and jam the pull seal exit port as the pull seal is removed from the cartridge.
1. A gasket seal for use in a remanufactured laser printer toner cartridge, comprising:
a flat substantially rectangular foam gasket having an exit port end and a distal end, a first longitudinal side and a second longitudinal side, and an elongated center opening;
a pull seal strip having a first end, a center section, and a second end;
a gasket sealing border removably adhering the pull seal strip to the foam gasket, the gasket sealing border extending substantially around the foam gasket center opening and adhering the first end of the pull seal strip to the foam gasket adjacent to the foam gasket exit port end and adhering the center section of the pull seal strip to the foam gasket adjacent to the foam gasket distal end;
the pull seal strip second end extending loosely beyond the foam gasket distal end and adapted to be folded back over the foam gasket;
the foam gasket exit port end substantially forming right angles with the first longitudinal side and second longitudinal side, the gasket sealing border adjacent to the foam gasket exit port end substantially following a line segment not parallel to the foam gasket exit port end.
2. The gasket seal for use in a remanufactured laser printer toner cartridge of claim 1 , wherein the gasket sealing border adjacent to the foam gasket exit port end substantially follows a line segment that is about 22 degrees off parallel to the foam gasket exit port end.
3. The gasket seal for use in a remanufactured laser printer toner cartridge of claim 1 , wherein the gasket sealing border comprises a hot melt border.
4. The gasket seal for use in a remanufactured laser printer toner cartridge of claim 1 , wherein the pull seal strip of comprises a polyester film.
5. The gasket seal for use in a remanufactured laser printer toner cartridge of claim 1 , wherein the gasket sealing border adjacent to the foam gasket distal end forms a relatively blunt point.
6. A remanufactured laser printer toner cartridge, comprising:
a toner hopper section having an elongated opening to allow toner to pass to a roller section;
the roller section connected to the toner hopper section, the roller section and toner hopper section together forming a cartridge seal exit port between them;
a toner hopper gasket seal adhered to the toner hopper section and having a center opening aligned with the toner hopper section elongated opening, the toner hopper gasket seal having a pull seal strip, the pull seal strip extending through the cartridge seal exit port at substantially a right angle to the cartridge seal exit port;
a gasket sealing border formed on the toner hopper gasket seal and completely surrounding the gasket seal center opening, the gasket sealing border serving to removably attach the pull strip to the gasket seal, the gasket sealing border and pull seal strip substantially closing the gasket seal center opening;
the gasket sealing border adjacent to the cartridge seal exit port substantially following a line segment not parallel to the cartridge seal exit port.
7. The remanufactured laser printer toner cartridge of claim 6 , wherein the gasket sealing border adjacent to the cartridge seal exit port substantially follows a line segment that is about 22 degrees off parallel to the cartridge seal exit port.
8. The remanufactured laser printer toner cartridge of claim 6 , wherein the gasket sealing border comprises a hot melt border.
9. The remanufactured laser printer toner cartridge of claim 6 , wherein the pull seal strip of comprises a polyester film.
