best food flask reviews

This particular thermos is made by the same producer, whose product won in our ranking. However, in here we received smaller and most of all lighter version of the product. Just like the first product, we find here stainless steel exterior and interior. In addition to that, we can choose one out of four colours. However, the warranty is not as long as before. We can hope for 5-year assurance from the manufacturer. Incredibly huge benefit of using FUNtainer Food Flask made by Thermos is its light weight and compact size. You can store it almost anywhere and there is little chance something bad will happen to the thermos. Of course there are some drawbacks of this tool that results from its size. 290 ml cannot store much food. It also performs worse than bigger equivalents in terms of warmth-maintenance.

In general the price for the product is in average range. However, when we compare size to price ratio, we can see it’s quite expensive.

  • Very compact

  • Light

  • Colour variants

  • Wide opening

  • Very easy to unscrew

  • Too small for adults

So how to find the right product? Take a look at our tips!…

If none of these products drew your attention, you might as well look for thermos by yourself. However, in order to find legitimate food box that will keep the warmth for a long time and at the same time will be functional, you need to know several things regarding these products. If you wish to read the whole article about proper selection of food flask, we encourage you to go to:

If; however, you want to learn these tips in a nutshell, take a closer look at the content below!

The type of flask

In order to find the right food flask, we have to take into account the style in which thermos was made. You see, there are different shapes of food flasks for drinks and for food. Therefore, we should always look for flasks that provide us with wide mouths. Because of that, it is easier to eat directly from the jar and it is also easier to wash it. Additional advantage of wider openings is also the process of loading and unloading the food. However, bear in mind that larger openings can influence the cooling process of your meal.


Functionality of food flasks is as important as their durability. Before we decide on particular model, we should take a look at all aspects of using it. See whether the manufacturer designed the product for the types of meal you are going to use. There are plenty of food flasks with the purpose of soups and other liquid food. In order to find the one that will suit our expectations we have to read all the notes left by the producer as well as the reviews of other people. Then we will learn if the chosen flask gives us all functionalities we need.

Additional accessories

This particular aspect is not as essential as the rest, but it is very nice to have food flask with additional utensils. In most cases legitimate manufacturers make lids of the openings capable of holding the meal. Thanks to that we don’t need to eat our food directly from the jar if we don’t want to. There is always a choice. Second addition that surely helps us out is spoon. Look for folded spoon made of durable material. It is recommended to look for stainless steel spoons, not plastic ones.


The material used for creation of the thermos is probably the most important matter. It is due to the fact this material is responsible for holding the heat as well as keeping our cold food fresh. Back in the days producers used glass and glass-alike materials to create food flasks. Sadly, they were too fragile for traveling, therefore we encountered plenty of problems with them. Then, we could find more durable solutions. However, these solutions included coatings that could flake off and contaminate the fluids we pour inside. That is why we should always look for stainless steel material, which doesn’t use any coatings and can still hold the heat for a long time.


In case of modern thermos, we don’t need to worry about durability. In most cases we receive a very long guarantee, which ensures that the product we have chosen is valuable. Except for long-lasting warranty, we should also take a look at material. Plastic or, what is even worse, glass food flasks are now the matter of past. Right now, the most reasonable option is to purchase stainless steel thermoses.

Summary – is it hard to find the right food flask?

To be honest there are plenty of producers that can meet our requirements. Of course we should always double-check all information before purchasing. Except for that, we should also pay attention to customers and their opinions. Usually feedback left by other people shows how effective the given product is!
