How It Works

Thermos is a brand name for a type of vacuum flask that is cleverly designed to keep the contents at the original temperature, whether they are hot or cold.

Vacuum flasks were first created at the end of the 19th century by a Scottish man named Sir James Dewar. This is why they are sometimes referred to as a Dewar flask or Dewar bottle, although the inventor decided not to look for a patent for his revolutionary product and never produced commercial flasks.

This invention led to a couple of German glassblowers creating the first commercial vacuum flasks, which they called Thermos. A number of companies then refined the product under the same name and eventually Thermos became the name that most people used for this type of flask to keep liquids either hot or cold

These flasks work in a very clever way, by creating a vacuum around the contents that stops heat being conducted in the interior. In this way, it is really made of two flasks – one within the other – that are joined together at the top and have a partial vacuum in between them.

These days, Thermos vacuum flasks come in a massive variety of shapes, colours and sizes. This means that it is a relatively simple task to find the perfect one for any particular use or occasion.

Features That Are Important

As we have just seen, vacuum flasks all work in essentially the same way, as the partial vacuum between the two sections keeps the interior temperature constant for hours at a time. However, that doesn’t mean that they are all exactly the same in every single way.

Indeed, there are a number of features that you will want to take into account in order to make sure that you make a good choice.

  • The time that it keeps liquids hot. This is something that varies from just a few hours to a full 24 hours in some cases. If you want the likes of hot tea or coffee on the move then the longer your Thermos vacuum flask keep its contents steaming hot the better.
  • The time that it keeps liquids cold. Typically, a good flask will keep stuff cold for longer than it keeps things inside hot. 24 hours is a fairly normal length of time for this task, which is great news if you like to have a refreshing drink with you on hot days.
  • Its suitability for food. While most people will use their Thermos flasks for holding drinks, there are also some models that are ideal for keeping food in too. In this case, you should look for an extra wide mouth that makes it easy to fill up and to eat from too.
  • The capacity. We all want a new thermos vacuum flask for different reasons, which is why we tend to look for different capacities from them. For example, if you go on long treks or camping trips then you will probably want a bigger capacity and more robust design than someone who just wants the odd cup of tea at work.
  • Easy to pour. Many of the best Thermos flask models come with a twist and pour top. This is great news, as it means that you can very easily serve your drinks without having to take the top off or risk spilling it every single time.
  • Cool on the outside. An absolutely essential part of any vacuum flask is the ability to stay cool on the outside even when something very hot is contained in it. If you feel that the outside is hot then there is probably a problem with it, as no decent flask should have this issue when it is working properly.
  • Attractive looks. One of the advantages to the quantity of different Thermos flask models around these days is that you can choose the look that is perfect for your needs. There are elegant flasks, sports models and fun looks to choose from.
  • The warranty. As with any product that you expect to use a lot over a number of years, you will get a great deal of comfort out of a good Thermos flask with a long guarantee. Some of the best vacuum flasks have warranties for as long as 50 years as a mark of their outstanding quality.
  • Useful accessories. Most hot drink flasks are pretty simple but some do come with useful accessories that make them that bit more attractive. For example, some come with a stainless steel serving cup, a long spoon or a tea hook. Again, how useful these things are will really come down to how you plan to use your flask now and in the future.
