1. The birth of thermos cups
In 1643, Italian scientist Torricelli created the pump pressure gauge and later proposed the famous theory of vacuum. This theory was of great significance for the emergence of thermos flasks, but it was not until the late 19th century, after the Industrial Revolution began, that thermos flasks began to take shape
In 1879, German physicist Dewar made a container of two thin glass layers with a vacuum in between to store liquefied gases in the laboratory. In 1890, British chemist Dunmus Gyauer made an improvement by coating the bottle wall with a layer of silver, which effectively reduced thermal radiation and minimized heat dissipation through glass. Thus, the Gyauer bottle was born.
The world’s first metal thermos was not born until 1893. It was released by James Dewar, an Englishman, at Royal College London, but it could only be regarded as a closed bottle. The two inner walls of this double glass container were covered with mercury, and the air between the two inner walls was pumped out to form a vacuum state. This type of vacuum bottle is called a “Duwa bottle” or “Duwa bottle”.
But at this time, there was still a certain gap from the thermos bottles we are familiar with in modern times. It was not until the 20th century that the commonly seen thermos bottles gradually took shape and were mass-produced.
2. Post thermos era
Insulated cups are derived from thermos bottles, and their insulation principles are similar. However, it was not until the 1970s that the innovation of stainless steel vacuum insulation technology ushered in a new era for insulated cups.
In 1904, the Germans took away the technology of “Dewar bottle”, improved it, established the THERMOS brand, and began to manufacture stainless steel thermos cups. In 1908, thermos cups entered Japan.
The period from 1925 to 1932 was the founding period of China’s thermos bottle industry. In 1925, scholars who returned from studying in the United States founded the first thermos bottle production company in Chinese history in Shanghai, opening the way for the development of thermos bottles (cups) in China.
In 1995, with the joint venture between Hong Kong and Japan, thermos cups began to enter the domestic market and a company was established. Today, China has become the largest market for thermos cups in the world. It can be seen everywhere at home, in the office, at school… and has become one of the indispensable necessities in daily life.
