Do you adore frequent outings? Are you a frequent participant in a variety of hiking trips? Or is your favorite hobby fishing? If you gave a positive answer to at least one question, it means that you know firsthand what the need for acquiring such a device as a thermos is. The modern market offers a wide range of such products. But how to choose a quality thermos from this set that keeps heat better?
The ability to retain heat is the main criterion when choosing
From any thermos they expect one thing - effective work. Its effectiveness is manifested in the amount of time period during which drinks or food remain hot or warm. Which thermos keeps heat better , that is more effective. And this is a key criterion when choosing the device in question. But so immediately, just by looking, to determine this characteristic is simply impossible. After all, it also depends on other factors. Here you can consider them.
The choice of a specific thermos model depends on several criteria:
- The purpose and time of operation. If the thermos is used on vacation as a reservoir for storing food and drinks, its hallmark is its ability to maintain temperature. Pay attention to the fact that the longer the estimated time of its use, the greater the volume it should be. And yet: the larger the capacity of the vessel, the longer it will be able to leave food or drinks hot. Here is a thermos that better holds heat - capacitive. But at the same time, if the thermos is intended for food, then its volume should be exactly the same as what your portion of food is. Ask: "Why?" Everything is very simple! When the thermos is completely filled, air masses are in its free cavity, which will lead to operational loss of temperature, no matter how high it is. Only a fully filled thermos will work as efficiently as possible and give warm food for several hours, or even days. The consistency of food also affects the food temperature in a thermos and the intensity of its gradual decrease. So, food in liquid form remains hot much longer than, for example, pasta.
- Type of tank. Thermoses can be used for drinks or food. There are also soup thermoses and thermos-mugs. But it is worth noting that they differ only in appearance. The design of the tank for drinks provides a narrow neck, an average indicator of the diameter of the cylinder and the lid, which can be made in the form of a cork and is equipped, as a rule, with a valve. A wide-neck thermos can also be equipped with cutlery. But if there are none, don't be upset! They are fixed on the tank body and can simply interfere with its carefree operation.
The structural basis of a liquid thermos can be a glass or metal flask. A glass flask is not as practical as a metal one, but its hygienic properties are incomparable. As for which thermos holds the heat better, the answer is clear: a vessel with a narrow neck. - Thermos material. The fixture can be plastic and metal. Moreover, the metal can also be different. It is only at first glance that they are all brilliant and the same. But if you pick up two different models, you can make sure that they are different in weight characteristics. It is difficult to say which thermos better holds heat - plastic or metal - but one thing is certain for sure - if a vessel made of metal is the same weight as a plastic one, then there is no question of its superiority and effectiveness.
And you can experiment ...
When choosing a thermos, it is most rational to conduct a kind of experiment. To do this, pour hot liquid into the tank and observe whether the temperature of the outer case changes in 7-10 minutes. If the case is heated, the thermos does not hold heat or does it very weakly. There is no point in such an acquisition. And if the purchase has already taken place, then the goods can be safely taken to the store and claim that you have come across a defective thermos.
And, of course, the manufacturer
Only high-quality thermoses serve faithfully. Quality is directly dependent on the manufacturer. If you prefer brands known to the world community and brands that have already managed to recommend themselves, then be sure that you, as a consumer, are guaranteed quality, efficiency and practicality.

To eliminate the vacuum space of residual air masses, an absorbent element is placed between the wall surfaces, due to which the intensity of heat exchange is minimized.
The manufacturer claims a 26-hour temperature regime.
This is a quality Russian thermos - reviews users only confirm this. But, according to buyers, an acceptable pricing policy is initially more attractive. After all, its cost is at the level of 750 rubles.
