When you’re a big fan of soup, you’ll almost certainly have days when it’s great to take some with you to eat on the go. While a lot of people associate flasks with tea, coffee and other hot drinks, they’re also perfect for soup too – did you know that there are food flasks as well as drinks flasks?

Below, you’ll find out a little about them – and which are a great choice to buy to use to keep your soup warm enough to enjoy throughout the day. As usual, you’ll find some links to buy them on Amazon too – however there’s plenty of other places to buy too if you prefer. We like Amazon because of their great prices, huge range to choose from and fast and affordable delivery options.

Thermos Stainless King Review

When it comes to flasks, Thermos are like to be the brand that immediately jumps to mind. Therefore, it’s no surprise they’re here topping the list. In fact there are very few others that people on the street would be likely to name off the top of their heads, so that brand awareness is something they’ve worked hard to build up and their flasks reflect that expertise.

This particular flask, the Stainless King Flask is available in a total of eight colours:

While colour is a big choice for a lot of people, it’s actually not going to make any difference beyond the aesthetic enjoyment you get from your purchase. If we look at the specifications of the flasks from Thermos, all colours are the same. They’ll hold 470ml of soup for you, which should be more than enough for most people’s lunch time treat. According to Thermos, hot liquids should stay hot for nine hours inside, and it’s also great for chilled contents too – giving you cooling for fourteen hours.

Hopefully that’s plenty long enough to maintain your food to enjoy, but even after that time period elapses, it’s not suddenly likely to change to room temperature, it’s just not going to be quite as hot (or cold!) any longer.

When it comes to the construction, this flask is made from an attractive, strong and effecting stainless steel core, with an outer shell in your chosen colour. Both these materials are perfect for cleaning, so long as you do so within a reasonable time frame after use.

As we all know, food can dry with concrete like properties, and no level of engineering from the manufacturer will stop that! All it needs is a quick rinse out as soon as is practical after use if you’re not in a position to wash up straight away.

The flask’s lid will obviously tightly seal in the contents, and is achieved by being used in two parts. The inner lid seals the food into the chamber of the flask, and includes a spoon which fits nicely into the top of it. The outer lid then fits over the top, also screwing into place, but once removed can be turned over and used as a cup or bowl.

WayEee Review

As we just saw with the Thermos, flasks are often available in different colours. The WayEee food flask comes in the following variations:

The WayEee flask keeps your food hot or cold for up to twelve hours, thanks to its effective stainless steel construction that’s created to be seamless for maximum insulation when the lids is secured and the vacuum forms on the interior of the flask.

It’s got a generous 450ml capacity too, so while a touch smaller than the Thermos above, it’s certainly in the same ball park.

Not to be outdone, this design also features a dual lid arrangement, complete with folding spoon. Again, this is perfect for soup lovers on the move, and thanks to its clever design, is a cinch to carry as it all fits together into a single unit until you’re ready to eat.

To get the maximum performance, the WayEee food flask is designed to gain pressure after sealing, so you need to be aware that there’s an air hole that acts as a valve beneath the spoon storage space. You’ll need to press the button and release some pressure in order to easily open the flask when it’s mealtime.

The flask carries a high rating on Amazon at the time of writing, you can check out the current score by clicking the blue button below. It’s always great to see overwhelmingly positive feedback from previous customers, and helps to have confidence in what you’re buying!

WisFox Review

You’ll have to like blue to go for this model, because it’s the only colour available for the WisFox food flask. For that reason, it’s lucky that it’s not the sort of colour that puts people off, although equally for many it won’t be particularly exciting either!

It’s earned its place because it’s a bigger flask then most alternatives, with a generous 750ml capacity.The great thing is, that three quarters of a litre of storage comes at a comparable price to the smaller soup flasks too.

(Now 43% Off RRP)

Both hot and cold food should be good with this flask for up to twelve hours, and in some cases you’ll find the WisFox Food Flask Insulated 304 Stainless Steel Food Jar capable of keeping chilled food cool for up to a whopping eighteen hours.

As with our previous picks, this flask comes with a folding spoon too, and additionally a couple of bonus extras too in a storage bag and sponge brush too thrown into the deal.

720°DGREE wunderJar Review

The food flask from 720°DGREE finishes up our round up of flasks, and like the Wisfox, is also limited to a single colour, in this case a dark grey. While there is not choice of colour, this one does come in two sizes – the standard 450ml option and a larger 650ml one too.

You’ll be getting up to nine hours to eat hot food and up to sixteen if you use cold contents with this flask, more than enough for most people’s lunch to stay pleasantly warm or cold ready to enjoy.

The 720°DGREE flask also uses what the manufacturer describes as pressure management in order to resolve the problem of struggling to open the WunderJar when it’s time to eat. It’s also worth noting that the lid conveniently doubles as a bowl to use at lunchtime too.

Of course, this will mean you can enjoy a pleasant lunch time treat for a fraction of the cost of buying convenience food when you’re out and about, and what’s more reduce the waste you generate by avoiding all that unnecessary packaging we all associate with fast food purchases.

Food Flasks FAQs

So, you’ve seen the products we like and read about them, let’s finish off with some more general information you might find helpful based on common questions.

What Can I Use In The Flask Other Than Soup?

You’ve probably picked up on the fact that we’re a site about soup making, but these flasks aren’t limited to soup alone. There’s no reason you can’t use these for coffee and tea, just as you would with a traditional hot drinks flask, these are just wider and shorter to make their capacity more helpful for food as well as liquids.

In fact, the foods you keep in them don’t necessarily need to be liquid either – you can use boiling water in the inner chamber to heat it up, prepare other foods to place inside then empty the water and pop your food inside. While liquids work best, this will give you a hot place from the start to keep solid foods warmer for longer.

In most cases, while you won’t get as long to eat before the temperature is lost as with a full load of liquid like soup, it’s still a solution to get you through a few hours to lunchtime.

Can You Put The Flask In The Dishwasher?

Just like the soup makers reviewed in the main part of this site, it’s not a good idea to use the dishwasher to clean soup makers or food and soup flasks either, unless the manufacturer specifically tells you otherwise. We’re yet to see one that’s marked dishwasher safe for the whole unit, although some have parts which are fine, perhaps the included spoon, bowl or even the entire lid.

Generally speaking, flasks work so well because they create a series of barriers between the food or drink inside the flask and the rest of the world that’s trying to return everything to the air temperature. If you subject your flask to the forces and temperatures inside a dishwasher, the water is far more likely to break through the seals separating those areas and reduce how effectively the flask operates. For the same reason, it’s wise not to leave them soaking in the washing up bowl for longer than necessary either.

How Are Soup Flasks Cleaned And Is It Easy?

You might be thinking that it’s a pain not to be able to use the dishwasher, but actually if you act in reasonable time, flasks are very easy to clean. If there’s a water source nearby, give them a quick rinse after use, and if not put the lid back on. Both of these will reduce the chance of the residue left inside the flask hardening too much and creating a challenge to remove when you do wash it up properly.

Of course, still make sure you give it a proper clean with warm and soapy water then rinse out properly, according the the manufacturer’s instructions at the soonest opportunity, but being careful to avoid the debris hardening inside will help a lot.

Getting into a routine with cleaning the as soon as you can after use will help to keep your soup flask in great condition.

The Soupy Summary

These neat flasks are brilliant for transporting your soup for lunch, or even an evening meal when you’re out and about all day. They’re particularly popular with people who spend a lot of time outdoors away from kitchens and other civilisation, providing a great solution for eating a hot and healthy meal. Recently though, with the huge popularity of healthy eating and soup making, they’re gaining mainstream popularity too.

With a good food flask, you’ve got the option to have a hot, health and nutritious lunch anywhere!
