Abstract
A fluid container for an ink jet printer includes a collapsible reservoir, a cap, and an electronic storage device. The collapsible reservoir is for containing a printing fluid and includes walls enclosing an internal space having a variable volume for storage and dispensing of a liquid. The cap for attachment to the reservoir includes a port for connection to the printer. The port is adapted to prevent air from entering the internal space from outside the reservoir as liquid is dispensed. An electronic storage device is configured to store data relating to the contents of the container. At least one electrical contact is associated with the electronic storage device and provided on a substrate.
