Don't you know how to choose a good thermos? In a short article, we will answer this and other questions in detail. Ready? Then let's get started!
A bit of history
The thermos was invented in the 19th century by the Scottish physicist James Dewar. He significantly changed the glass box designed to store liquid gas. Of course, it never occurred to him that in the future this invention would be used to store food. To begin with, the physicist changed the shape of the box, made it in the form of a flask with a narrow neck. Then he added double walls, between which there was a vacuum. This vessel was supposed to prevent the liquid stored in it from evaporating.
But the student of James Dewar, Reingold Burger, guessed to use a thermos for domestic purposes. For convenience, he equipped the case with a metal coating, added a stopper and a lid that can be used as a glass.
What thermoses are there?
Vacuum thermoses can be divided into two large groups: thermoses with a glass flask and thermoses with a stainless steel flask. The rest of the thermal utensils are not thermoses, they are various kinds of thermal containers in which there is no vacuum flask, but various heat-insulating materials or just an air gap are used, so they can be stored for a long timeheat (cold) they cannot. Further, thermoses are divided according to the type of products stored in them. There are thermoses for drinks, universal thermoses for drinks and food at the same time, food thermoses with a large neck diameter, children's thermoses for feeding babies. Next comes a large group of thermal containers in the form of: thermal mugs, thermal bags and, in fact, various types of thermal containers.
By the way, glass flasks have a lot of advantages over stainless steel flasks to keep in mind. First, glass does not interact with any food components, unlike stainless steel itself. Secondly, glass has zero gas permeability, unlike steel, which means that a thermos with a glass flask can theoretically serve you forever.
Why do you need a thermos?
Thermos, perhaps, can be attributed to one of the best and most necessary inventions for man. It perfectly holds both cold and heat. The thermos is irreplaceable in travel, at work and on rest. A good product can hold the desired temperature for up to two days.
In today's society, he is very popular. The main task of the consumer is not to miscalculate when buying it. A good thermos should be of high quality. Equally important is convenience. How to choose a good thermos? Let's talk about it below.
Purpose of purchase
In our time, there is a very large selection of thermoses on the market. You can purchase a product with a narrow neck for drinks, with a wide one - for soup or second courses. The case of a modern thermos is also made of variousmaterials - metal, plastic, glass. Which thermos is better, let's consider right now.
If you are a fan of traveling, hunting, fishing, or just often going out into nature, then stock up on a thermos with a metal case, as it is shockproof, you can safely take it with you on a hike. Be sure to choose a stainless steel coating, otherwise the service life of such a device will be short-lived. The disadvantage of the coating is that food sticks to it.
The thermos with a plastic case is ideal if you, for example, take lunch with you to work or travel in comfort, and do not mind having a cup of hot coffee or homemade tea on the way. The disadvantage of a thermos with such a coating is that plastic easily absorbs food odors, therefore, it requires more thorough washing and prolonged ventilation.
Thermos with a glass case is better to use at home. It is ideal for brewing herbs or if you need to keep your favorite drink at the required temperature for a while. The disadvantage of a glass bulb is its fragility. However, it is considered to be the best thermos because it keeps the heat longer than any others.
Models
In addition to various coatings of the case, thermoses come in different models. It is advisable to approach the choice of the right one thoughtfully. Next, we will look at what models exist today, and try to decide which thermos is right for you.
The choice of a more convenient model for you depends on the purpose for whichneed a thermos. So, in more detail:
- Thermos, the body of which is made in the shape of a bullet. Ideal for any drinks. Compact, has a narrow neck and a strap.
- For home use, a pump-action thermos is suitable, which keeps the desired temperature for a long time and is equipped with a button for supplying liquid, which is very convenient, because you do not have to open the lid.
- Thermal mug. This is a kind of mini thermos. It is small in size but does its job well. Useful if you have a short trip.
- Ship thermos is indispensable if you need to keep several dishes hot at once, as it has several containers of different capacities with sealed lids. Made of plastic for ease of use.
- A versatile thermos with an airtight lid will come in handy if you plan to use it for both drinks and food. The model is equipped with a folding handle and a lid that can be used as a mug or cup.
- And, finally, a thermal bag. The disadvantage of this model is that it does not hold the desired temperature of the product for long. However, this time is enough if you want to keep your lunch or dinner hot, for example.
Which thermos is best depends on your needs!

These are the best thermos companies that use high technology to produce durable and quality products. Also, manufacturers have been attentive to the design, which pleases with its diversity.
German companies specialize in isothermal cookware, the quality of which, of course, is beyond praise, but not everyone can afford the cost.
Russian firms produce only thermal dishes and accessories. The quality of domestic thermoses is not inferior to foreign ones, and the price is more acceptable.
And yet, if you want to buy a good thermos, it is not recommended to chase the cheapness of products from an unknown manufacturer. After all, such a product can be made of low-quality material, even life-threatening.
Cost and place of purchase

Consumer opinions
The needs of each of us depend on the type of our activity. A good thermos requires careful selection. Many buyers after purchasing this or that thing share their opinion with other consumers.
Don't know what a good thermos is? Customer reviews are very diverse, and they can help you make the right choice.

In general, how many people, so many opinions, but all buyers agree on one thing: it is better to buy thermoses from well-known manufacturers.
Summarize
If you choose thermoses, reviews (which is better, the question is difficult), of course, are of great importance. It is very convenient to rely on the opinion of those who already use the product of a particular model. But still, one should not be guided onlybuyers' comments. When choosing any product, you need to carefully study not only the characteristics, but also the appearance.
