When was the paper clip invented? Norwegian John? Waller 1899 applied for a patent for this design in Germany. A year later, the cornea? Brosnan designed one called. konaclip？ Our paper clip has also applied for a patent in the United States. In Britain, a gem company soon produced the double oval gem paper clip that we are familiar with now. At that time, a large number of paper clips began to be sold.
Although the paper clip is considered as the most humble invention, it is also a simple and practical miracle. Centuries before the invention of paper clips, some other materials, such as pins and silk threads, were used to fix paper, but these things easily pierced the paper and caused damage to it. The invention of the paper clip solved this problem well, but its real success still depends on the metal wire, because the metal wire has good elasticity and is easy to stretch and bend.
Although the invention of paper clip has been supported by users, researchers still want to further improve its related design. In order to prevent the paper from being scratched, the tip of the metal wire is ground more roundly. To 1907, what is the gem brand? Easy to slide, can fix letters, documents and notes well without damaging the paper? Our double U-shaped paper clips occupy a dominant position in the market.
So the question is, who is the inventor of the paper clip? Is it the person who had the original idea, or the person who invented very useful materials? Although there is still some controversy about the inventor of the paper clip, Norwegians proudly believe that their compatriot John? Waller is a real inventor. During World War II, the Nazis occupied Norway, and Norwegians regarded paper clips as a symbol of national unity. They pinned paper clips on their collars to express their feelings of unity and opposition to Nazi occupation.
Long after the end of World War II, Norwegians erected a 5-meter-high stainless steel monument in the shape of a paper clip in the center of the capital Oslo. Today's paper clips are colorful plastics, and there are many new shapes, but none of them have been proved to be outstanding. So, that's why after so long, until today, paper clips are still playing a role.
