A pen ink cartridge is a convenient device used to supply ink to a pen. It is a small, replaceable disposable or refillable container that fits into a pen quickly and easily, avoiding the mess that can occur when using a drop bottle to fill the ink directly.
Type 1. Disposable ink bags: These are small plastic tubes pre-filled with ink that can be discarded after use. They are very convenient and suitable for travel or use in situations where the ink cannot be easily refilled. 2. Reusable ink sac (converter) : This type of ink sac allows the user to draw ink from the ink bottle and inject it into the pen. Common forms include piston type, push-pull type and pneumatic type. advantage 1. Convenience: Replacing the ink sac is cleaner and faster than directly filling the ink. 2. Portability: It's easier to carry a spare ink sac than an entire ink bottle. 3. Reduced risk of leakage: Reduced leakage problems that can be caused by frequently opening the pen to fill the ink.
