Thermos Bottle Day Hero

Sir James Dewar

Sir James Dewar (1842–1923) was a Scottish chemist and physicist who invented the vacuum flask in 1892. While he never patented his invention, it was later commercialized by others under the 'Thermos' brand. His work on cryogenics and the liquefaction of gases directly led to the need for such an insulated container.

History of Thermos Bottle Day

The history behind Thermos Bottle Day is unclear, but the story of the Thermos bottle itself is traceable to the early 20th Century. Though the word ‘thermos’ has become a household name used for any vacuum flask that stores either hot or cold liquid, Thermos is a brand name — the trademarked brand name of Thermos L.L.C.

In 1904, the Thermos flask was registered as a patent by German inventor Reinhold Burger, who later partnered with Albert Aschenbrenner and Gustav Robert Paalen. However, they were not the original inventors of vacuum flasks. Before this, a Scottish scientist known as James Dewar invented a vacuum flask for storing liquefied gas. It was not meant for everyday use. Although he was the first to create the vacuum flask, Burger was the first to register it as a trademark. Later, Dewar sued the Thermos company but sadly, lost the court case.

Thermos later faced similar problems as their trademark became a household name to the point that the word ‘thermos’ was now used to refer to similar products from other manufacturers, making it a ‘genericized trademark.’ Dictionaries even began including thermos as a word instead of a proper name. In 1962, a judge finally ruled that due to Thermos’ publicization of their product and lack of diligence protecting their trademark, thermos with a small ‘t’ could be used generically. However, the uppercase ‘Thermos’ solely belonged to the company.

How does a Thermos bottle keep liquids hot or cold?

The vacuum inside the bottle significantly reduces heat loss or gain, while the reflective inner surface helps to minimize heat transfer by radiation. This combination ensures liquids maintain their temperature for hours.

While the Thermos brand still exists and produces a wide range of insulated products, the term has entered common lexicon as an eponym, much like ‘Kleenex’ for facial tissues, describing any similar product.

Think of a world without thermos bottles. We appreciate James Dewar's innovative idea. Because of bright minds like his, our world becomes easier every day.

Without thermos bottles, we’d have to finish our drinks almost as soon as they’re poured to avoid lukewarm liquids. Thankfully, we never have to experience this, as cold stays cold and hot remains hot.
We love entrepreneurism
We love how Thermos has aggressively pursued its vision. Since 1904, the company has diversified into other products. They now produce various items, such as food jars, mugs, tumblers, and coolers.
