Product Information

Thermos is a well known brand and that fills you with confidence right from the off. But what really sets this flask apart from the rest is how durable it is. It’s made from stainless steel just like the ValueTalks flask, which as we have learned, is really robust and designed to stand the test of time.

For kids, there are smaller capacity ones of around 300ml. These don’t weigh as much, will fit into lunch boxes and, as kids generally eat less, there’s nothing going to waste. The leak-proof design also promises to keep your food hot for up to six hours or cold for up to eight. Thermos is the most well-known brand for making insulated flasks so they’ve got it down to a fine art.

Of course, there is a limit to this and eventually the soup will get cooler but some of the best soup flasks can keep the soup warm for up to 24 hours! Now that’s impressive. And you might think that this means just keeping the soup lukewarm but we’re talking still hot, so much so that you have to blow it before you can eat it. The cylindrical jar has a wide base with a lid that’s coated in a grippy material that makes it much easier to unscrew. Finally, think about how easy it is to clean. Some flasks are dishwasher safe but it’s almost always better to wash it by hand. For this reason, a flask with a wider opening is generally better.

It’s lightweight and compact, with insulated walls that are designed to keep your food hot for 9 hours or cold for 14. In testing, we found that the contents of the jar had cooled significantly by the end of the 6 hours. It was still warm to the touch, but you would probably want to reheat it depending on what you’re storing. The only downside we could find was that the opening was a bit more tapered compared to some of the other options, which meant cleaning up wasn’t as straightforward. To remove this, simply add a couple of tablespoons of white vinegar to the flask and top it up with water. Leave this for a couple of hours or overnight to give it time to work.

Where to buy an insulated food flask

You want something lightweight but you don’t want something that compromises durability for this. Therefore, it’s really essential to look at the materials and choose something with a good balance between the two. Flask Size Some flasks are also designed with the intention of maintaining a low temperature for cold food. While not fully refrigerating them, flasks designed for this purpose will usually keep things cold longer than they keep things hot. But, some flasks are not meant for this, so bear that in mind. INSULATED food flasks are perfect for hiking trips where you don’t have anywhere to heat up your meals but they can also be great for the office or school. Soup flasks aren’t the most expensive items in the world but they naturally have a range of prices according to the quality. It’s a good idea to set a budget and shop within that for anything you buy but remember that it’s often better to buy something a little more expensive that’s going to last and perform well. Design If you are out and about and want some delicious soup later in the day then the best way to ensure your food stays warm is by using a soup flask. This is the main reason for buying one. But what’s more they’re so versatile; you can use them to take soup to work or when you’re out hiking, cycling, camping and so much more.

If the food inserted into your Food Flask is producing lots of steam, please let the steam evaporate before closing your Food Flask to avoid pressure build up. Food flasks vary in price depending on how big they are and how long they will keep your food warm.Sandwiched between the inner and outer layers is a void - this vacuum stops the heat from the inner layer reaching the outer layer as heat can only be conducted through particles, whether it’s in the air, through liquids or solids. Next, think about how long you would need to keep your food warm for. Look for ones that will retain heat for at least six hours. You can also get larger ones of over 800ml, which might suit one very hungry person or a lighter lunch for two. Earlier, we talked about how most soup flasks are designed with a stay cool exterior but this isn’t always the case. You’ll want to choose a flask that doesn’t get hot to the touch on the outside as this can lead to burns and is a serious safety issue. Budget You could be forgiven for thinking that all soup flasks are the same. After all, they’re designed to do the same job, aren’t they? This is true to an extent but as with anything, there are various features and differences between products which might make one soup flask slightly better for your needs than the next.
