Ink-jet print cartridge body

摘要

An opening extending to an outer surface of a cartridge body is closed by a polymeric material sealant plug formed in situ. The cartridge body includes an ink flow pathway which interconnects an ink reservoir chamber to an exit port. The opening, which extends from a duct of the ink flow pathway of the cartridge body to the outer surface of the body, is closed by injecting a polymeric material into the opening. It is currently preferred to use a thixotropic material such as a thermoset urethane adhesive.
