Despite the general computerization, the transition to electronic document management, the development of Internet services for the exchange of written messages and the achievement of technology in the field of information recording, the old kind hand does not give up its positions. Imagine the life and work of many people without this simple and common writing instrument is impossible. No matter how fast the technology developed, humanity will not give up the “analog” letter for a very long time. And with him there will be a need for pens.
By the way, saying “pen”, we mean a pen, that is, a device in which ink from the built-in tank comes to the writing unit. The traditional meaning of this word as a subject for writing, which needed to be dipped in ink, is no longer used.
There are entertaining statistics. 92% of the world’s inhabitants use pens. If we recall that recently the population of the Earth exceeded 7 billion inhabitants, and every year people buy 4-5 pens each, it is not difficult to calculate the annual volume of the market – more than 30 billion pens sold per year.
Today there is a huge choice in the market. Cheap options for those who need to just write, advanced design pens, “demonstrators” of status and financial capabilities, collectible editions, products from precious metals as works of art … All these pens are completely different both in design and functionality, but they are all Can do one thing – leave traces on paper.
Types of handles by design
Despite the fact that mankind constantly strives to improve the writing tools, there are not many invented types of pens. Logically, the first to become feather fountain pens. Try to attach to the pen ink container began in the middle of the XIX century, but for the time being, experiments ended unsuccessfully. Handles turned out unreliable and then did not write at all, then they spilled a lot of ink, leaving blots.
In 1884, the situation was corrected by the insurance broker Lewis Edson Waterman. Having missed a profitable contract because of the rejected handle (at least, the legend says so), he set out to develop a more perfect writing device. Waterman was the first to guess that to ensure the smooth supply of ink, it is necessary to organize the flow of air into the tank. To do this, he began to use two channels between the reservoir and the tip – the first “went” the ink in one direction, the second – the air in the opposite direction. The Waterman’s pen was primitive by modern standards, but for its time it became a huge breakthrough. It could actually be used. However, there were also shortcomings – the fountain pen worked only at the usual atmospheric pressure, but, for example, it began to flow at a high altitude.
