Buyers Guide For Thermos Flasks

For many walks of life, a Thermos flask is absolutely essential. It doesn’t matter whether you’re a trucker looking for something to store hot coffee on the go, or an office worker looking for a reliable flask for their desk, a humble Thermos fulfils a wide variety of roles.

Finding and buying the right Thermos flask, then, is all the more important. There are a variety of features to consider and, to help in your search, here are some of the most important things to consider when buying a flask.

Size

This is relatively simple – how much do you want to store? Flasks can range from half a litre to 2 litres or more. Of course, there’s a practical issue to consider too. While smaller flasks need to be refilled more often, they are easier to carry and fit into bags more efficiently.

Similarly, you may wish to invest in a smaller flash if it has additional features – such as the ones discussed in this article – that a larger Thermos container in your budget might be lacking. Here are a few combinations that you should consider:

  • A larger flask can certainly hold more, but how long can the flask keep up the temperature? A big flask isn’t much use if it still needs refilling just to maintain the correct heat.
  • Practicality is always an issue. Does the size fit in your bag? Does it go well with any bowls, mugs or cups you wish to use? If your kitchenware is quite small or narrow, a large flask might have too wide a lip, leading to instances of spilling.
  • Price will always be an issue, too. If you have a budget, you can often go down in size to meet your target. On the other hand, a larger flask can be worth the extra money, especially if it have a potentially long lifespan with plenty of use ahead of it.

 

Temperature Time Frame

These containers don’t keep their internal contents hot or cold forever. Depending on the design, material and construction of the Thermos flask, the time frame for this could range from just 6 hours to an entire day. Typically, these items keep items cold longer than they are able to retain the heat on hot items.

With that in mind, it’s often important to look for high quality products if you’re looking to contain hot items on a regular basis. Again, this is very much dependant on your needs. In an office with access to fresh coffee, a shorter time frame isn’t a problem but, on the other hand, a longer period is ideal for travellers.

When considering these time frames, you might also want to consider that the temperature doesn’t just switch at this exact point. The temperature will either warm up (in the case of cold items) or cool (as is the case for hot items) over time, gradually matching the room temperature. The rate it does this well depend on the flask and it’s vacuum design, but it’s an important factor to consider. A flask that promises heat for 6 hours means the temperature stays at approximately the right level for that amount of time. In truth, it’s a little bit of a grey area, so it might be worth looking for something that exceeds your requirements to avoid being disappointed.

 

Practical Functionality

Depending on what you’re planning to store, a different type of flask might be worthwhile. Traditional flasks are tall and slender, making them efficient at pouring liquids with a decent level of finesse and control. On the other hand, a shorter, stockier design is ideal for storing soups and thicker materials and these often border in a similar area to Thermos food jars. Here are a few other issues to consider:

  • Does the design look ergonomical and easy to handle? An overtly large flask might be difficult to grab or use with a secure handle, while smaller designs can easily fit into an average sized hand.
  • How do the dimensions of the flask fit with where you intend to keep it? Kitchen shelves, personal bags and office desks all have various size requirements, so you should ensure any such device is able to fit comfortable.

 

Additional Features

Speaking of functionality, are there any additional features you might wish to consider? A handle isn’t required, but it might be something that suits your environment. A strap or carrier bag, on the other hand, would be ideal for someone on their feet quite a lot, or just want to ensure they can keep their hands free.

Likewise, a built in cup is very useful for people on the go. If you can’t guarantee access to clean cups or mugs, then using the one on your flask (many designs integrate this into the lid) is a highly beneficial. Not all Thermos flasks have this feature so it is something you should look out for if its important to your needs.

 

Ability to Wash & Clean

Even if you only fill the Thermos with the same fluids everyday, it still needs a clean once in a while. Thankfully, the vast majority of Thermos flasks are built out of stainless steel or other internal metals that are easy to clean. When most people have a washing machine, this is an easy task to accomplish. On the other hand, if you don’t have this kitchen appliance, you might want to look at the size and shape of the design. Is it ergonomic and does it look like you can reach into the bottom when cleaning?

 

Style & Design

Finally, there’s no accounting for taste. The most ‘traditional’ or typical design for a Thermos flask is to rely on the reflective appeal of stainless steel, using a few black trimmings for everything else. However, if you have a strong sense of fashion and design, there are a number of colourful, vibrant variants available. Whether you want a retro vibe or a high-tech aesthetic, a Thermos can be just like any other accessory and match your existing tastes.

As you can see, there are plenty of factors to consider when purchasing a new flask or Thermos container. Fortunately, if you know what you need and focus on the criteria this is most important to your situation, you can easily narrow down your selection into just a few leading products. From there, it’s just a case of finding the one that’s right for your individual situation.
