All About Ballpoint Pen

Bella Mclaine asked:

Pen is the general instrument that is being used to write commonly on a paper. In ancient times, people used to write with the help of ink. But with the changing time a new discovery to write was known as pen. Like say of above 90% of world population is using pens in their daily life. A ballpoint pen was known in British English as a brio. A ballpoint pen is a writing instrument which features a tip that is automatically refreshed with ink. A pen used for writing has its writing point a small bearing that transfers ink stored in a cartridge onto a writing surface. A ballpoint pen has an internal chamber filled with a viscous ink that is dispensed at the tip during used by the rolling action of a metal sphere ranging from 0.7mm to 1.2mm in diameter of brass, steel or tungsten carbide.

One of traits of ballpoint pen is that ink just gets dry enough as soon as it comes into contact of paper. It is very cheap and dose not requires any maintenance for if a ballpoint gets damaged as compared to fountain pen. And so looking to its features and other factors people have started opting for ballpoint pen rather than fountain pen and has become the daily mode of writing instrument. Ball point has become the most popular tool for everyday writing.

There are various types of ballpoint pens available in the market.

– Disposable pens are mainly made up of cheap plastic material and can be discarded when you find the ink is been consumed.

– Refillable pens can be low quality of metal or plastic made which tend to be higher in price. The refill once uses complete internal ink then fall in the need to be refilled again with an assistance of ink pot. The simplest type of ballpoint pens have a cap to cover the tip when the pen is not in use, while others have a mechanism for retracting the tip. The fundamental concept that is worked behind this mechanism is a button at the top and powered by a spring within the pen apparatus. You will also come across even other locking kind of system like pair of buttons, a screw, or a slide.

– Roller ball pens combine the ballpoint design with the use of liquid ink and flow systems from fountain pens.

– Space pens combine a more viscous than normal ballpoint pen ink with a gas pressurized piston which forces the ink toward the point. This design allows the pen to write even upside down or in zero gravity environments.

Thus, ballpoint pen has its own significance because of its utilization in routine life. Black ballpoint pen has gained much of fame within short time in all ballpoint products.
