The thermos flask is possibly the most recognizable and widely used product in the world. It has been present in our everyday lives for more than 110 years, since its invention by two world-renowned chemists, Nicholas Appert and Louis Pasteur.
The invention itself is attributed to many different people, but it was eventually credited to these two prominent gentlemen in history. The story of how it originated begins with an idea no one could have imagined before the industrial revolution began.
How the Idea Originated?
It is believed that the first thermos came to be due to the invention of the vacuum teapot by a Chinese scientist, Wang Youxing, in 1740. After many tests, it was discovered that the tea temperature would stay pretty much constant for a very long time. At this point, people realized that there was potential for heat transfer to take place in the cup. Because of this, they began to look into ways in which they could use this discovery.
The idea of putting hot water in a container would most probably occur to someone if they had taken the time to examine how it works. First, you need to boil water and then cool it down. The best way to cool it down is through the use of airtight containers. This is because, with airtight seals at all entryways, there will be no spillages whatsoever. If this concept is applied to a thermos, it could have been an enormous breakthrough.
Who Invented the Thermos Flask?
Who invented the thermos flask? It was a time when scientists were trying to improve its teapot and heat retention properties. In 1793, Nicholas Appert came up with a design that would allow for heat retention to maintain the temperature of things such as food over long periods. He called it the bottle airtight, and this is where the real journey of discovery begins.
The next generation, Louis Pasteur, also showed an interest in the bottle airtight. On August 24th, 1852, he ran some tests on it and filled it with some broth that had been left out for some time. The temperature of the broth was already lower than the temperature outside at that time. Then, he got some more broth and put it back in the bottle airtight. For six months, he never opened it. After six months, when he opened it up, the broth was still warm even though there was no fire or any kind of heat source present. Later on, Pasteur figured out that this was because of certain microorganisms in the air that would keep things warm even when there were no external heat sources around.
Changes Made by Pasteur in a Thermos Flask
Pasteur was able to carry out experiments to prove that there are microorganisms that cause food spoilage. Then he began to try and figure out how the microbes caused this so he could come up with methods of sterilizing food. He discovered two methods of doing this. One was to boil food at extremely high temperatures. The other method is known as pasteurization, which involves the use of heat for a specific amount of time.
How Was the Thermos Flask Invented?
The invention of the thermos flask was not an easy task. It involved a very lengthy process that took many years to finally reach its conclusion. In 1881, a German scientist, Carl Von Linde, came up with a method of vapor compression in which he used a separate unit to take hot air and replace it with cold air so that compression would take place. This is how the idea of how a thermos flask came about.
A certain man, Sir James Dewar, was intrigued by this process and wanted to put it to the test. So he came up with a design for a thermos and went about to try and make it happen. It took him six years to finally come up with the right idea. He called it the non-vacuum flask because of its nature of not having any vacuum within it. Once this design was perfected, he successfully got heat inside the flask without having any leakage. He finally arrived at a prototype that looked very similar to what we see today.
His invention of the thermos flask did not reach an enormous practical application. However, it did lead to further developments in scientific thermometers and travel bottles for scientific experiments. So he is truly an important figure who revolutionized the world of science in many ways. He is also known as the Father of Thermos because of the impact his discovery had on it.
The Invention of the Thermos Flask Was a Great Idea
The invention of the thermos flask was a great idea. It revolutionized how we preserve certain food and beverages in our homes and bodies. A major part of the invention revolved around retaining heat and staying warm even in icy and hot conditions. This is because the design was very effective in maintaining its product’s temperature for a very long time.
Developments in Thermos Flasks Through Ages:
1854: Leak-tight and airtight, and vacuum-seal flasks were first used.
1886: Vacuum insulation for hot air was invented in France by Augustin Fresnel. It allowed for the creation of the thermos flask in 1892.
1893: The invention of the thermos flask was made by Carl Von Linde in Germany.
1909: Thermos flask became commercially available in the United States; it came into popularity that year, with sales reaching $22.16 million dollars.
1914: Vacuum insulation for hot air was improved as well as thermos flasks.
1950: The thermos flask became common in the United States. Military, commercial, and private users used it.
1970: Thermos flasks became popular with the consumer in the United States; they were used for offices, refrigerators, and restaurants.
1980: Thermos flask used to preserve food was invented in Japan.
1990: New types of thermos flasks were developed. NASA developed the first one.
2007: Thermos flask was made by Gregg King, a British-based company which is today called Fillers Ltd.
The thermos flask has experienced incredible improvements through the years. It has become one of the most important devices for preserving food and beverages, especially in modern times. The product was first developed for military purposes, commercial purposes, as well as private purposes. The design of the flask today is widespread due to its effectiveness in storing food and beverages at various temperatures.
The thermos flask initially came into the market as a military device. Soldiers wanted to preserve food that was needed for them to eat often. This required developing a device that would keep food fresh even when it was exposed to extreme climatic environments.
The invention of the thermos flask was indeed a result of many people with one goal in mind. Today, with almost all modern conveniences, it has become easier to survive in any climate with the help of this fantastic tool.
