Who invented the ballpoint pen

- Nov 13, 2019-

Who invented the ballpoint pen? Today, when I was writing my homework, I used a ballpoint pen to write homework. I suddenly had a question asking my mother: "Mom, this ballpoint pen is very easy to use. Who invented the ballpoint pen?" Mom asked me to finish my homework and check it out online. After finishing the homework, I turned on the computer to solve the answer to this question:

 In the past, in Europe, people used ink pens to write text, but ink pens easily left ink stains and soiled hands or paper. In the late 1930s, a Hungarian named Razlobi and his brother, the chemist Georg, developed a quick-drying pen after several years of experimentation. The main body of the pen is a tube filled with quick-drying ink, and a ball is embedded at the top, which enables the ink to be smoothly written on the paper. Later, the brothers created a ballpoint pen in 1943 under the sponsorship of others.

 These inventors are so good that the invention of an item is in front of us. It seems that we must also study hard, and after we have sufficient knowledge, we will invent something in the future.

 Extended reading:

 1. The origin and history of the ballpoint pen

 The earliest name of the ballpoint pen was in 1888. An American journalist named John Lloyd designed a pen that used a ball as a nib, but he could not make it into a product that people could use.

 In June 1943, Biro and his brother Georg (a chemist) applied for a new patent to the European Patent Office and produced the first commercial ballpoint pen, the Biro ballpoint pen. Later, the British government purchased the right to use the patent ballpoint pen, making these ballpoint pens available to the Royal Air Force crew.

 A ballpoint pen is a writing instrument that uses ink to rotate the ink onto the paper. After the Second World War, ballpoint pens were introduced to China. The savvy businessman made a big "negative pen" advertisement, and opened the market by the Yuwei of the atomic bomb that exploded in Japan. In fact, the "ball-point pen" has nothing to do with the atom, but the pronunciation is similar.

 2. Information on Chinese made ballpoint pens

 The ballpoint pen's pen tip is divided into a ball and a ball seat on the pen tip. At present, China's tungsten carbide beads with a diameter of 0.5-1.0 mm can not only meet the domestic production needs, but also a large number of China's finally made ball-point pens are expected to replace the import port. However, the ball seat with a diameter of only 2.3 mm, whether it is production equipment or raw materials, has long been in the hands of Switzerland, Japan and other countries. China needs to produce 38 billion pens a year to import more than 1,000 tons of steel for the production of nibs at a price of 120,000 tons, and pay foreign exchange of 15 million US dollars. In order to put "Chinese writing" on tens of billions of ballpoint pens, the country started the key project in 2011. After five years of unclear failures, under the electron microscope, Taigang Group finally saw the “additive” evenly distributed nib steel, and the test was successful in September 2016.

 After more than ten large-scale steelmaking, the first batch of machinable steel was finally released. This batch of 2.3 mm stainless steel wire can be proudly written with the "Made in China" logo.

 3, the origin of the ballpoint pen

 When Hong Kong Li & Fung imported the ballpoint pen from the United States into Hong Kong, the product did not have a Chinese name because the "atoms" had the meaning of victory at that time. The most popular terms were atomic belts, atomic energy, atomic bombs, and the name "ball pen". The representative means that the use is endless and the source is inexhaustible.

The other is that it uses the tip of the pen to roll to reach the purpose of writing, so it was originally called "ballpoint pen", and some people read it as "circle pen", and gradually evolved into the pronunciation of "ball pen".

 In 1966, Yutu Stationery Factory produced the first ballpoint pen in Taiwan.

 4, the inventor of the ballpoint pen

In the 1930s, the Hungarian journalist Bayro Mr.Biro invented the first ballpoint pen (BallPointPen), a pen with a rolling ball as a pen tip. It can be written on the surface of the handkerchief and on the surface of the wood without injecting ink. The ballpoint pen costs up to $10. This was very expensive at the time. The nib has a "small steel ball" with a diameter of about 0.1 cm. It is made of alloy of chrome and steel. It is very pressure-resistant and wear-resistant. The small ball is in the nib of the pen tip. If the pen is slipped over the paper, As soon as the small ball rolls, the ink in the upper pen tube is brought to the paper. This small ball is the biggest feature of the ballpoint pen.

5, the principle of the ballpoint pen

 The working principle is that under the dual action of the pressure of the refill and the gravity of the ink, the ink flows from the oil pipe to the ball seat of the pen head, and then the ink adheres to the ball. When writing, the ink adhered to the ball adheres to the writing surface as the ball rolls on the writing surface, forming a handwriting, that is, the purpose of writing is achieved. Due to the writing principle of the pen, the pen used on the earth cannot be used in space, so the invention of the space pen was made, which was specially used for the spaceman in the gravity-free or microgravity state of space.
