Abstract

The present invention provides a toner container assembly including a sealing assembly. The seal assembly may include an outer retaining ring having a non-adhesive carrier, a first adhesive layer on a surface of the non-adhesive carrier, and a first opening through the outer retaining ring. The seal assembly may also include a foam ring including a second opening therethrough, wherein the foam ring is attached to the outer retaining ring with the first adhesive layer, and a double-sided adhesive layer , the double-sided adhesive layer is attached to the foam ring. The seal assembly may also include a solid foam disk including a first slit therethrough and a second slit therethrough, wherein the first slit is perpendicular to the second slit and the The solid foam disc is attached to the foam ring by the double sided adhesive layer.

Description

technical field [0001] The present invention relates to the field of printing devices, and more particularly, to toner containers for use with printing devices. Background technique [0002] Printing devices such as laser printers use powdered toner to form text or images. The toner in the portable toner container (eg, toner bottle or cartridge) is placed in the printer, and the toner is dispensed from the container. For example, a dispensing auger from a printer can be inserted into the opening in the container, and then the bottle and / or dispensing auger can be rotated to feed toner into the auger. The toner is then delivered to the print engine. [0003] During insertion or removal of the auger from an opening in the container, or during shipment of the printer, solid powdered toner can leak from the container into the printer. Periodic maintenance is typically performed to remove toner contamination from the interior of the printer, since the toner can reduce print qu...
