Best Soup & Food Thermos Container Reviews

by Rick Goldman

A lukewarm beverage on a scorching hot day can be properly irritating for the person unfortunate enough to be forced to drink it.

Imagine going out on a camping trip and bringing a bottle of water or lemonade only to find out that it turned into a warmish slush from hell! Tough stuff, indeed, but it can get even worse, believe it or not!

As you know, there are some beverages and liquid meals ( such as soups, stews, and broths ) that don't really fare well when exposed to heat. Leave a vegetable soup out in the open for a couple of hours and it will form unsightly bubbles on its surface, rancid smell of acidic food, and texture of industrial glue.

Nasty stuff, indeed.

Luckily enough, this doesn't mean that there is no way to bypass these annoying AND potentially health hazardous issues. Thanks to a brilliant invention called thermos, you can now carry hot and cold beverages wherever you like without worrying they'll be spoiled when exposed to extreme temperatures.

Of course, this doesn't mean that you can keep a beverage safe from the outside factors infinitely. Even the best thermos will eventually stop providing thermal isolation to the beverage inside. However, if you'd like to keep your liquid foods, juices, and beer cool and warm (depending on what sort of matter is in question), a thermos can triple or quadruple the amount of time you'll have it ready at your disposal!

In this article, we'll talk about the top 8 thermoses for food and soup currently available on the market. All of these are tough and reliable, so whichever model you choose, you won't make a mistake, really. To help you make your choice more easily, we've also prepared a brief buying guide where you can see the most important features you need to look for in a thermos.

Right then, without further ado, here's the deal!

Buying Guide For Best Soup & Food Thermos Container

Even though you can still find some old thermoses of yore, which are made out of cheap metal and some BPA-rich plastic parts, most of the modern-day thermoses are actually made out of some sort of stainless steel.

To ensure the thermos you're buying is sturdy and capable of surviving adverse conditions, get a model that's made out of food-grade stainless steel if possible. This sort of metal has been specifically treated for food storage and preservation, so there's will be no better material than this one!

When it comes to various accessories such as carrying bands, caps, and protective pieces - these are often made out of either plastic or rubber. If it is, indeed, plastic, make sure that it's BPA-free.


Depending on what purpose you aim to use your thermos for, its volume is going to play an important role in its efficiency and usefulness. This is why these thermos manufacturers make their products in different sizes, to begin with.

If you're only planning to keep cold beer or water in your thermos, a smaller, 10-ounce model can work just great for you. It will be easy to carry and pre-chill, so it can be a perfect option for people who are constantly on the go.

On the other hand, if you plan to pack your or your kids' lunches in it, obtaining a larger thermos makes more sense, of course. Some of the larger models can hold from 15 to 22 ounces (there are probably some models that can hold even more), which is pretty much enough for a full meal to fit inside!

Cap Design

Since the cap is the only opening on a thermos, and these utensils are used for preserving the temperature of the food inside, it's important to pay attention to the design of the cap itself.

Generally speaking, there are three main types of thermos caps - valve caps, glass caps, and screw caps or lids. While all of these will do a pretty good job of retaining the temperature inside, there's another thing to keep in mind here - leaks.

Out of these three, the glass ones are the most likely to leak if there's liquid inside the thermos. So, if you plan on putting beverages, soups, or stews inside your thermos, a screw cap may be the best solution. The valve ones are also good, but they're also more complex meaning that if something goes wrong, it can start leaking. Also, food particles can get stuck into their little crevices, which can be annoying to wash.


Thermoses, as a rule, are relatively inexpensive.

Even the most cutting-edge models won't really impoverish your home budget, and the good thing is - once you buy a high-quality one, you're good for years!

As far as the factors determining the price of these temperature-retaining utensils, the most important are the material used, the size, and then the manufacturing brand in question.

Other than that, certain features such as specialized valve caps and additional collapsible spoons, for example, can also add a couple of bucks to the overall price tag.

Those parts are all BPA-free, so you needn't really worry about the potential harmful implications of this chemical.

( If you decide to purchase it, of course. )

On the outside, this thermos features a standard stainless steel build and then a sort of protective cap on top and on its bottom.

The build, materials in use, and the insulation principle are also all roughly the same. The contents of this thermos will keep warm for up to 5 hours and their cool for up to 7 hours. Of course, it's always a good idea to preheat or precool the thermos itself before actually filling it with food or water. This can lengthen the temperature retention time for a little bit.

Its stainless steel build will ensure its near indestructibility and its exterior is resistant to the 'sweating' effect of the instances when you put cold things inside.

Advantages Of Using Food Thermos

  • It goes without saying that life can get pretty hectic for families during the work week. In between after-school activities for the kids, dinners with friends, tough work schedules, and trying to maintain healthy relationships, it can become extremely difficult to fit well-balanced meals into the mix.
  • When it comes to making sure that you eat lunch every day while you're at work, it seems to be much easier to grab some fast food rather than pack a lunch before you leave in the morning. Unfortunately, eating out every day can turn into an extremely expensive habit, and more importantly, eating fast food all of the time is absolutely horrible for your body. Luckily, food thermoses can turn a stressful problem into a nonexistent one.
  • While there are plenty of advantages to bringing your lunch to work in a thermos, the biggest benefit of a thermos is its ability to keep hot food hot and cold food cold. Many people don't have access to a microwave or a refrigerator in their workplace, which is why so many of them choose to eat out on a regular basis.
  • Instead of struggling to figure out what to have lunch every day, or having to deal with the same boring sandwich day after day, people are choosing to bring a thermos to work filled with their favorite foods.
  • Thermoses are also great for those of you that meal plan for an entire week. Before you go to work in the morning, just grab your meal for the day, heat it up, and throw it in your thermos. Not only will you have a delicious meal, but it will stay warm until you're ready to eat it.

Of course, thermoses can't hold everything. For example, you wouldn't put a steak in your thermos, but you can use it for pasta, soup, and a variety of other great foods.

How To Properly Carry Food In Your Thermos

Now that the possibility of better lunches has been presented to you, let's discuss how to actually carry your lunch in a thermos.

Great Foods For Thermoses

It's clear that you can't put whatever you want into a thermos, so let's talk about all of the things that you can put into a thermos. For starters, thermoses will keep anything warm that is liquid or semiliquid. For example, thermoses are great for soups, chilis, and beans. Pasta and casseroles can also go into thermoses as long as there is a substantial amount of sauce included in it. Just remember that there needs to be a little liquid to stay warm and you'll do just fine!

Prepping Your Lunch

Before you add your food to the thermos, add some boiling water to your thermos and allow it to sit for a couple of minutes. While you're doing that, heat up the food that you're wanting to put inside of it until it's warm to the touch. To ensure that the food is heated evenly, it's recommended that you heat it up on the stove rather than a microwave.

Safety First

It's absolutely essential that you thoroughly clean your thermos before each use to avoid bacteria from building inside of your food. As stated before, heat up your food just before you leave for work to avoid it having to sit in the thermos longer than necessary. Keep in mind, if the food drops below 140 degrees for longer than two hours you can run the risk of harmful bacteria growing on your food.

Clean Up

It's not safe to re-heat thermos leftovers, so if you don't eat all of your lunch, make sure to throw the rest of it away at the end up the day. Using boiling water, rinse out the inside of your thermos thoroughly and then wash it clean with just a bit of soap and water. Make sure that the inside of the thermos is completely dry before putting the lid back on it.

Frequently Asked Questions On Best Soup & Food Thermos Container

Q: What Container Keeps Foods Hot?

  • Ans: If you're looking for a great way to keep your meals warm while you're at work or your kids are at school, you have a couple of options to work with. The first being the food thermos that we were talking about previously. The second option is using an insulated lunch bag to house a sandwich bag filled with boiling hot water.

Q: How Long Does Food Stay Hot in a Thermos?

  • Ans: The answer to this question is completely dependent on the type of thermos that you're using. Your food will only stay hot or cold for as long as the thermos that you purchase says that it will. Trying to keep it in there longer than the stated amount could cause harmful bacteria to develop. Also, remember that once you open the thermos you should eat it all at once or throw away the leftovers to avoid the development of bacteria.

Q: Does Tupperware Keep Food Warm?

  • Ans: While Tupperware is great for storing and easily transporting food, it isn't capable of keeping your food warm for long periods of time. For example, if you put hot food directly into the Tupperware it will stay warm for a while, but it will eventually cool down. If you're looking for something to keep your food warm for several hours, then you should consider purchasing a thermos or an insulated lunch box.

Q: How Do You Keep Food Hot in a Thermos?

  • Ans: Keeping food hot in a thermos is actually an extremely easy thing to do. Right before you leave for work or school, heat your food up on the stove (using the microwave will cause your food to be heated unevenly). Then, put the food inside of the thermos, and as long as it's over 140 degrees it will stay warm for several hours.

Q: Is Using a Stainless Steel Thermos Safe?

  • Ans: Stainless steel is one of the mostly commonly used materials for thermoses. Not only does it keep the food warm for many hours, but it's also safe for your food to sit inside for quite some time. Keep in mind, if you're sending your child to school with a thermos full of hot food, make sure to send a note to the teacher asking for help so your child doesn't burn themselves.

Q: How Do I Keep My Sandwich Warm for Lunch?

  • Ans: It goes without saying that it can be a pain to enjoy a warm meal while you're at work, but that's where thermoses or insulated lunch bags come in handy. When it comes to keeping your sandwich warm, though, use an insulated lunch bag and a plastic bag filled with boiling water. Put the plastic bag in the bottom of the insulated lunch bag and it will surely keep your roast beef or meatball sandwich warm for many hours.

All in all, a sturdy, well-made thermos can make your every meal away from home feel and taste exactly like the one you eat at your dinner table. Indeed, whether it's camping outdoors and you need a cold beer, or you're off to work and need a hefty and warm lunch during the pause, taking your own thermos with you can really be a lifesaver!
