ABSTRACT:
A method and device to prevent the refill of cartridges, including inject and laser printer cartridges. The device includes a cage made of hardened drill resistant material inserted within the central reservoir of the cartridge to prevent drilling into the cartridge. The device also includes a bit grabbing mesh designed to grab or catch any drill bit able to penetrate the drill resistant cage, thus impeding the ability of a refiller to drill holes into the central reservoir. The device also includes at least two pressure sensitive check valves that close if a refiller attempts to introduce refill ink either by forcing it in under pressure or by drawing it in by means of a vacuum created within the central reservoir. Finally, the device includes a number of packets containing an ink altering material that would be released and foul any refill ink during an attempt to refill the cartridge.
