What constellation is the pen _ What constellation is the pen name of the pen?

There is a small crack in the center of the nib, and the size of this crack is just enough to control the ink flow and make it flow out properly. If the pen tip is stressed, the crack will become larger and the ink outflow will increase.

Pen is a widely used writing tool, which was invented at the beginning of19th century. 1809, Britain issued the first batch of patent certificates about water storage pens, which marked the official birth of pens.

In the early water storage pens, ink could not flow freely. When the writer presses the piston, the ink begins to flow. After writing for a while, he has to press it again, otherwise the ink will not flow out. Of course it's inconvenient to write like this. By 1884, an employee of an American insurance company named Waltman invented a capillary ink supply method, which solved the above problems well. The pen tip of this fountain pen is detachable, and the ink is injected with a small dropper.

The earliest pen that can absorb ink by itself appeared in the early 20th century. It skillfully uses a piston to absorb ink. Pen was developed step by step, and the commonly used capillary pen was not invented until 1956.

The "brother" ballpoint pen of the pen was born later. 1888, four years after Wolman invented the fountain pen, Robbie of the United States proposed a new concept pen, which was different from the fountain pen, but installed a ball on the nib. When writing, the ink stays on the paper as the ball rolls. This is what people call a ballpoint pen today. Unfortunately, Robbie's attempt failed, on the one hand, because the ball did not roll well and could not write; On the other hand, the ink flowing through the beads can't be controlled, and there will be a lot of water leakage. The invention was delayed.

More than half a century later, 1943, a Hungarian printing factory was named laszlo? Joseph? Bike's proofreader made a ballpoint pen.

Bike found a round tube, filled it with oily pigment, and changed the nib of tap water into a steel ball, thus the world's first ballpoint pen was born. Later, Bick provided this invention to the Royal Air Force. Soon, an airplane factory in Britain launched the first batch of commercial ballpoint pens.

At that time, an American businessman named Renault decided to invest in mass production of this ballpoint pen. At the end of World War II, the atomic bomb was successfully made in the United States! In order to impress the audience and attract customers, Renault ingeniously called his ballpoint pen "ballpoint pen". In this way, ballpoint pens have entered the era of competition with pens.
