Ink filler is material used inside pens to hold ink without it leaking.
In more detail, ink filler:
- Acts as a reservoir: The primary function is to hold a quantity of ink within the pen body.
- Prevents leakage: It helps control the flow of ink, preventing uncontrolled leakage from the pen tip or other openings.
- Provides controlled ink flow: The filler facilitates the gradual and consistent release of ink onto the writing tip as needed.
- Common types: Examples include:
- Absorbent materials: These fillers, often made of porous plastic or felt-like material, soak up the ink and release it gradually.
- Cartridges: Pre-filled, self-contained units are inserted into pens and provide a clean and easy way to refill ink. These cartridges often contain a separate, smaller section to collect extra ink.
