Working Of Thermos Bottle

A thermos or vacuum flask is a great invention that is designed to store water or beverages while retaining the temperature. This keeps the content of the bottle hot or cold over a long duration.

Sir James Dewar invented the first thermos flask in 1892, and hence it is also known as the Dewar flask or bottle. This invention was later re-designed for commercial purposes by two German glassblowers, Reinhold Burger and Albert Aschenbrenner, in 1904.

The thermos bottle consists of two vessels in the interior between which the vacuum is present. The double-wall vacuum insulation is what retains the temperature of the liquid.

The bottle is usually made with a food-grade stainless steel interior that may be accompanied by a copper or reflective coating. The outer vessel is also built using stainless steel with a powdered layer of silicon.

BEST Themo Flask Bottles

When hot water is poured inside the bottle, it prevents the transfer of heat by convection, conduction, or radiation. The vacuum present between the vessels acts as an insulator preventing the heat from escaping due to conduction. The bottle comes with a lid or a tight stopper that prevents heat transfer through convection. On the other hand, the copper or reflective coating reflects the heat into the liquid.

Thus, the water or beverage remains hot for a long duration. Something similar is also seen in the case of a cold drink. The tight stopper prevents heat from entering the bottle while the vacuum insulator prevents the heat from entering via conduction. It retains the temperature of the drink for hours by not allowing it to come in contact with the room temperature.

Why Should I Get A Thermos?

A good thermos can give you an easier start to the day. You just make your coffee in a rush and then sip it on the go.

Gone are the days when you had to scald your mouth on a boiling cup of coffee, or worse, throw it in the sink because there was no time to enjoy it. And of course, a good, leak-proof thermos is essential when camping. 

Regardless of features, the best thermos is the one that’s just right for your coffee-drinking habits.

A poorly constructed one will struggle to keep your coffee at the right temperature, or worse, risk leaking everywhere in your bag. Besides camping, you can take your thermos with you to work, school, picnics, afternoon walks, parties (perhaps with a dash of liqueur), dates (cute to share if you have an extra mug, and you can impress with your delicious coffee), absolutely anywhere.

The qualities to look for also depend on how and where you are going to use it. There are a lot of different thermoses on the market, so it can be daunting to choose The One. Luckily for you, we’ve put together a review round-up to help you on this quest.

How To Choose The Best Thermos For Coffee

First, you need to ask yourself what type of thermos is the most appropriate for your personal use.

BEST Themo Flask Bottles. Pouring coffee into a green thermos.

Size Matters

Is the thermos going to be used only by yourself, or are you looking to share it with camping partners or a date? How much coffee do you usually brew and consume?

If you’re looking for a shareable thermos, or you tend to drink a whole pot of coffee over the day, you should be going for one with a large capacity. It will be heavier and take up more space in your bag, but you can be sure you have enough coffee to keep you going.

If you prefer to keep it small and light, you should go to one of the smaller options. If you’re constantly on the move, perhaps a thermos that can fit in car cup holders (or even a travel mug) will be the right choice for you.

Insulation Is Key

Insulation determines how long the thermos can maintain temperature, for either hot or cold drinks. The insulation’s effectiveness is determined by how the thermos is constructed. The best thermoses are made with double-wall stainless steel and are vacuum insulated.

In contrast, some cheap thermoses are made with materials like tin or even plastic, which just cannot compete in the insulation department. While cheap thermoses can be fine for commuting and other short-term use, they’ll struggle to retain temperature for more than a couple of hours:

To build a good thermos, what you want to do is reduce [these three] heat transfer phenomena as much as possible… plastic in the foam is not a very good heat conductor.

This is what really differentiates cheaper thermoses from higher-end ones; you definitely want to keep your coffee hot. So if you’re looking for a thermos for overnight use, you will probably have to invest a bit more.

Design And Other Features

While size and insulation are some of the most important things (2), there are also other features to look out for. The design of a thermos can have a huge impact on the ease of use. Everyone values different things, so there is no single right answer here – just think about what you most appreciate in product design.

Here are some things to look out for:

  • Is the lid or cap easy to open and close?
  • Does it have a serving cup?
  • How fast is it to clean from the inside?
  • Does it have a handle or straps?
