Invention: Ball-point Pen

 John J. Loud, an American, received the first patent for a ballpoint pen in 1888. However, it was not commercially successful and eventually his patent expired. László Bíró, a lawyer and occasional inventor from Hungary, wanted a pen that could write on rough materials as well as paper. He made significant improvements to the design and invented a practical ballpoint pen, which appeared in 1943. When Milton Reynolds and Francis Horne started selling ballpoint pens in 1945, they quickly became popular worldwide. The invention of the ballpoint pen is often credited to László Bíró because of his important improvements to the design. A ballpoint pen is a writing tool that uses a small rotating ball to put ink on paper, allowing for smooth and controlled writing. Ink in ballpoint pens is often pushed by a piston, spring, and capillary action to keep the ink flowing consistently. Fountain pens have caps and the ink flows smoothly from the tip. The ballpoint pen uses a rolling action and capillary action to release ink, making it more convenient for daily use. The downside of ballpoint pens is that the ink can dry out if the pen is left open for too long. Ballpoint pens are easy to write with and are useful for many writing tasks, from taking notes to signing papers. They are a precise writing tool that has changed the way we write since it was invented. Every second, more than 125 ballpoint pens are sold, making it one of the most popular writing tools in the world. All ballpoint pens can be refilled, which makes them a more eco-friendly choice compared to throwaway pens. The ballpoint pen has a small rotating ball at the tip. If the ink doesn’t flow well, it can get clogged and may need cleaning or replacing. This common writing tool has revolutionized the way we write, offering a convenient and reliable method of writing.
