A recording medium cartridge in which the quality of external view can be prevented from deteriorating by protecting a writing print layer against damage at the time of ultrasonic welding. The ink layer (20) is obtained by adding a writing filler (21) and resin particles (22) having a mean particle size not smaller than that of the writing filler (21) into ink (23). The resin particles (22) abut against a welding horn (9) to prevent the writing filler (21) from being dropped off or deformed through ultrasonic vibration.

Why it's free to use
- Filed April 24, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 24, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 24, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
