The walls of the product should protect the contents from external low temperatures, and also do not let the heat from inside. The heat capacity of the walls of the thermos must be maximal, and the thermal conductivity, on the contrary, is minimal. Otherwise, food and drinks will quickly cool down.

In general, the product has only a few basic parts: a neck, a gasket, a lid, a container and a flask. Each of the parts performs a certain function. A flask, for example, is an internal vessel where food is located. Between the bulb and the container there must be a layer of thermal insulation, which reduces the thermal conductivity and increases the heat capacity. A container is an outer vessel. Some thermoses for soup and the second can be equipped with a carrying handle and a special folding spoon.

Purpose

When choosing a thermos, it is worth paying attention to a few basic parameters. First of all, you should determine the purpose of the product. There are several types of thermoses.

In addition, the thermo mug has a very comfortable lid. The neck of the thermos is also made of non-heated material. This allows you to drink a hot drink directly from the container.

One awkward movement can lead to the fact that the bulb just dissipates into thousands of small fragments.

The thermos container can be made of metal. Usually, to create such products use materials that are not susceptible to rust. Therefore, one should not worry about corrosion in this case. It will not appear.

Not the best option - plastic flasks. First of all, products made of such material are very poorly kept warm. Of course, mirror coating can significantly improve the situation. Another drawback of such thermos is fragility. The bulb can quickly deteriorate, breaking or breaking.

External housing

The thermos for the soup and the second one consists of several parts, and each of them can be made of any material. The outer shell can be made of plastic. This material greatly facilitates the weight of the thermos. For many, this moment is very important.
