Pen’s Technology • A pen is a tool – Used for writing or drawing – Filled with a colored fluid, such as ink.
• A ballpoint pen is a pen that – Uses a small rotating ball made of brass, steel or tungsten carbide – To disperse ink as you write.
History of the Ball Pen • Hungarian journalist Laszlo Biro was well aware of the problems with normal pens. • Biro used a quick drying ink in a new type of writing instrument. • To avoid clogging his pen up with thick ink, he proposed a tiny metal ball that rotated at the end of a tube of this quick drying ink. • The ball would have two functions: – It would act as a cap to keep the ink from drying. – It would let ink flow out of the pen at a controlled rate.
How Does a Ball Pen Work • The tip of a ballpoint pen, the part that writes, is very tiny metal ball in a socket. • As you write, the ball spins, so that the ink is put evenly on to the paper.
Key to a Ball Pen • The key to a ballpoint pen is, of course, the ball. • The ball rotates freely and rolls out the ink. • The side of the ball which you can’t see is in contact with a narrow plastic tube filled with ink. • So that ink always moves evenly over the ball and makes the pen write smoothly.
Roll-On vs. Ball Pen
Roll-on antiperspirant uses the same technology as Ballpoint Pen
Mechanism of Ball Pen • The tiny ball is held in a socket.
• The back of the ball is exposed so it can pick up ink from the reservoir.
The Ink • Ink is a fluid or paste that comes in a variety of colors -- usually black or dark blue -- used for writing and printing. • Modern quick-drying inks usually contain three things: – The vehicle – Coloring ingredients • Pigments • Agents • Lacquers
– Additives
