Lucky for us, it’s becoming more common and more affordable to have one. Which in turn, represents another issue – which one’s the best one for you? Solution – read our Best Thermos For Coffee article to find out!

Why It’s Called A Thermos?

A thermos is a colloquial word for insulated vacuum flasks/mugs, just like terms like Aspirin, Jello-O, Q-Tip, and Scotch tape. Thermos, LLC didn’t invent the term “thermos.” In 1892, Sir James Dewar invented the first vacuum flask technology but he didn’t patent this invention. But Thermos LLC did.

The Mechanism

The thermos is made of 2 containers – one inside another. The interior container is narrower, which creates a void or space, between 2 containers. That’s why the name, “vacuum flask,” delays both the conduction and convection of temperature. Containers are stainless steel made as their heat transfer scale is super low compared to other metals. Therefore, the best thermoses are made of stainless steel.

Why You Should Have A Thermos?

A good thermos makes life easier for you. Just pour your coffee in it and sip it on the go. Since it’s an insulated mug/flask, you can hold it in your hands safely. Also, its insulation helps you to drink your coffee from it in a relaxed and prolonged manner. So no worries about scalding your mouth or hands.

It enables you to drink coffee when you’re camping, hiking, and cycling. The thermos flasks are easy to fit into your backpack.

Besides camping-like rough usages, you can also take and use a thermos at your workplace, school, picnics, and even parties.

If you’re on your own or with a partner(s), modern-day Thermoses can carry enough coffee for that too! So depending on your drinking requirement and style, you can pick a large, small, or medium-sized thermos.

If you’re constantly on the move, pick a thermos that will fit in your car cup holders (or use a travel mug).

The best thermoses do have double-wall stainless steel vacuum insulation. You can buy cheap tin-made or plastic-made thermoses which are fine for commuting and other short-term uses.

Quality Of The Steel

Many thermoses have this 18/8 stainless steel tag on them. It means, there’s 18% Chromium and 8% Nickel mixed in with the steel. Chromium is a corrosion-resistant material, thus used to construct hot water thermos. Remember there should be a minimum of 11% Chromium in the stainless steel, to be rust-resistant.
