Abstract
A resilient seal for insertion into an ink delivery port of an ink cartridge of an inkjet printer includes a blind hole through which an ink supply needle of the printer can pass. A membrane is formed integrally with the seal and closes the blind hole. The ink supply needle penetrates the membrane when the cartridge is inserted into the printer. The penetration in the membrane closes automatically upon removal of the cartridge from the printer.
