Who invented the ballpoint pen and who invented the ballpoint pen

In 1942, the Argentine Biro José Ladislaus, based on his years of observation and research, designed and manufactured a ballpoint pen, and since then, it has carried out many experiments and improvements and established a company for production, and was first sold in Argentina, which was widely welcomed and praised by people. In 1948, he sold the patent for the ballpoint pen to Parker in the United States. Since then, the ballpoint pen has become the most versatile and popular writing instrument in the world.

On October 24, 1985, Biro José Ladislau, the inventor of the ballpoint pen, died in a hospital in Buenos Aires at the age of 86. Friend! The ballpoint pen has provided us with a lot of help and convenience, and the ballpoint pen is a friend of mankind!

We love it, and we can't live without it. Let's remember the inventor of the ballpoint pen, Mr. Biro José Ladislaus!

The ballpoint pen was born in 1944 and was invented by a Hungarian Radislo Bíró: Biró was responsible for proofreading in a press press, and when he used a fountain pen to change proofs, he often experienced soaking and blurring, so Biró began to wonder if he could try to make a different writing instrument to replace the fountain pen. The printing ink dries quickly and doesn't smudge the paper, so he decided to make a pen that uses the same ink.

However, this sticky ink cannot flow out of the normal nib. With the help of their brother George, who was a chemist, they devised a pen that used capillary action to send ink to the ballpoint.

The ballpoint pen is the ballpoint pen invented by its mother.

The ballpoint pen was invented by a Hungarian named Birro. He's a journalist, he.

When using a fountain pen, sometimes it was not very convenient, so he wanted to invent a pen that could not easily cut the paper. He first turned to his brother, a chemist, to help him research a ballpoint pen oil, which, unlike ink, had to be sticky. After many years, they finally made a sticky ink for use on ballpoint pens, which are made of ballpoint nibs that are not easy to scratch the paper and easy to carry, so they are very popular.

The ballpoint pen was invented by the Hungarian journalist Ladislo Bíró and his brother Georg.

Ballpoint pen refers to a pen that brings out the writing medium through the ball rolling at the front end of the pen or refill, according to records, in 1888, the name of the ballpoint pen first appeared, which was designed by the American journalist John Lauder, but it was not made into a commodity at that time, and then in 1985, the British market also had a similar non-writing ballpoint pen, but because of its narrow use, it did not become popular.

The ballpoint pen in the true sense was invented by the Hungarian journalist Ladislo Biró and his brother Georg, Biro was well aware of the problems of ordinary fountain pens, so after many experiments, he finally invented the first commercial ballpoint pen - Biro ballpoint pen, and applied for a patent, after which, the British bought the right to use this ballpoint pen, and it was very well received at the time.

Development: In order to promote this commodity, the merchants made a big fuss about it and the atomic bomb in Japan at that time, and named it "ballpoint pen", but in fact, the ballpoint pen has nothing to do with the atomic bomb, and because of its convenient writing, it quickly became popular all over the world, after the Second World War, the ballpoint pen was introduced to China, and it is still one of the main writing instruments in our country.

The inventor of the ballpoint pen was Las Lobayro. A ballpoint pen is a pen that brings out the writing medium by rolling a ball on the front of a pen or refill. A ballpoint pen is a pen that uses tiny rotating balls made of brass, steel, or tungsten carbide.

Ink can be released onto the paper while writing. The ballpoint pen is very different from its predecessors, reed pens, quill pens, metal nib pens and fountain pens.

Structural principle

The writing principle of the ballpoint pen is mainly to use the ball ball to produce friction in direct contact with the paper surface when writing, so that the ball rolls in the ball seat and brings out the ink or ink in the refill, so as to achieve the purpose of writing. A ballpoint pen is a pen that uses ink and different pigments to write. The nib of the pen is a small steel ball.

The small steel ball is embedded in a small cylindrical copper bowl, and then connected to a plastic tube filled with ink, and the ink flows down from all sides with the rotation of the steel ball. The pigment of ballpoint pen ink is a dye. There are three main ink colors: blue, red and black, among which blue ink is the most used.

In the past, the pigment components in blue ink were salt-based blue and salt-based blue lotus, and the solvents were oxidized castor oil and ricinoleic acid. Because salt-based dyes are not light-resistant, heat-resistant, acid-alkaline, they have poor durability and have been eliminated.

The ballpoint pen was the first to appear.

The name was given in 1888 by an American journalist named John Lauder, who designed a pen that used a rollerball nib, but he failed to make it a convenient commodity.

In 1895, there was also a commercialized non-writing ballpoint pen on the British market, but it failed to become popular because of its narrow use. In 1916, someone in Germany also designed and produced a new type of ballpoint pen, whose structure was closer to today's ballpoint pen, but the performance was inferior and failed to attract widespread attention.

In June 1943, Bíró and his brother Georg (a chemist) applied for a new patent with the European Patent Office and produced the first commercially available ballpoint pen, the Biro ballpoint pen.

The modern fountain pen was invented by the American Waterman in 1809.

The Hungarian journalist Elszl Bíró collaborated with his brother George to create the first ballpoint pen in 1938.

Now the so-called water pen and gel pen are all improved products of ballpoint pens.

Westerners have long known about the use of quills and other convenient and quick writing tools, and later continued to innovate and invent pencils, fountain pens (in fact, the first metal dip pens appeared in the Roman Republic BC). Excavated in the ruins of Pompeii, now in the National Museum of Nepal), ballpoint pens, and introduced to China, played an important role in promoting the spread of Chinese culture (Lu Xun also once incisively expounded the role of the fountain pen). In this sense, the invention and introduction of the pen to China contributed far more than the use of paper.

The ballpoint pen was invented in 1943.

In June 1943, Bíró and his brother Georg applied for a new patent with the European Patent Office and produced the first commercially available ballpoint pen, the Biro ballpoint pen.

Later, the United Kingdom** purchased the rights to use the patented ballpoint pens, which made them available to the crew of the Royal Air Force. In addition to being stronger than traditional fountain pens, ballpoint pens can also be used at high altitudes at low pressures.

The name ballpoint pen was first coined in 1888 by John Lauder, an American.

In 1936, Biró of Hungary successfully experimented with a new ballpoint pen. A patent was filed on July 10, 1943, and it was put on the market in 1945.

The ballpoint pen was invented by the Hungarian journalist Ladislo Biró and his brother Georg, but the concept of the ballpoint pen was developed as early as 1888, but it was not commercialized at that time. Ladislo Biró and his brother Georg invented the ballpoint pen called the Biro ballpoint pen, which has since undergone many improvements in the process of use, and finally finalized it.

The inventor of the ballpoint pen is:

According to records, in 1888, the name ballpoint pen first appeared, which was designed by American journalist John Lauder, but it was not made into a commodity at that time, and then in 1985, the British market also had a similar non-writing ballpoint pen, but because of its narrow use, it did not become popular.

The real ballpoint pen was invented by the Hungarian journalist Lab Sinson Dislo Biró and his brother Georg, Birro was well aware of the problems of ordinary steel Zheng pen, so after many experiments, he finally invented the first commercial ballpoint pen - Biro ballpoint pen, and applied for a patent, after which, the British purchased the right to use this ballpoint pen, and it was very well received at the time.

A ballpoint pen is also called a ballpoint pen

In order to promote this commodity, the merchants made a big fuss about it and the first atomic bomb in Japan at that time, and named it "ballpoint pen", but in fact, the ballpoint pen has nothing to do with the atomic bomb, and because of its convenience of writing, it quickly became popular all over the world, after World War II, the ballpoint pen was introduced to China, and it is still one of the main writing instruments in our country.
