If you are often on long trips, like outdoor activities or work 12 hours a day at the enterprise, then you will definitely need a thermos for soup and a second one. Such a product will keep the dinner warm for many hours. The main thing is to choose the right food thermos. To begin with, of course, it is worth determining what material you want the product from and for what purposes.
Thermos structure
The main purpose of such containers is to transfer finished dishes and preserve their heat. This indicates that the thermos for soup and the second has a special structure. The walls of the product must protect the contents from external low temperatures, as well as not to release heat from the inside. The heat capacity of the thermos walls should be maximum, and thermal conductivity, on the contrary, should be minimal. Otherwise, food and drinks will cool quickly.
In general, the product has only a few main parts: the neck, gasket, lid, container and flask. Each of the parts performs a specific function. A flask, for example, is an inner vessel where food is located. Between the bulb and the container there should be a layer of thermal insulation, which reduces the thermal conductivity and increases the heat capacity. A container is an external vessel. Some thermoses for soup and the second can be equipped with a carrying handle and a special folding spoon.
Destination
When choosing a thermos it is worth paying attention to several basic parameters. First of all, you should determine the purpose of the product. There are several types of thermoses.
Food is needed to keep food warm. Such a wide-necked thermos may have several containers included. Eating from them is much more convenient. Simply lay out the contents of the thermos.
Products for drinks, coffee and tea have a narrow neck. It allows you to gently pour the contents into circles without spilling it.
There are universal thermoses that have several compartments with necks of different sizes. This is just perfect. So, in a container with a narrow neck, you can pour tea or any other drink, and pour a soup in a container with a wide neck or put a second one.
The main thing is functionality
Thermoses are different and can perform completely different functions. For example, a thermomug. This product is equipped with a special handle made of materials that do not heat up. In addition, the thermo mug has a very comfortable lid. The neck of the thermos is also made of non-heating material. This allows you to drink a hot drink directly from the tank. The thermo mug can be used to brew coffee or tea, even when traveling. It is always convenient and practical.
For lovers of fishing, a floating thermos for soup and a second is ideal. This product, once in water, does not sink. The whole secret is that a thermos of such a plan is made of porous and fairly light materials. In some cases, this feature is appropriate.
The thermos bag can be carried without a bag. This product is equipped with a special strap. You can simply hang it on your shoulder, freeing your hands. Food thermos can be made in the form of a backpack. In this case, large amounts of food can be tolerated without being overloaded.
In addition, there are heated products. Basically, they work on battery or cigarette lighter in the car. Thanks to these thermoses, you can not worry about the fact that the food can cool. At any time, it is possible to warm it up.
Material also matters
At the moment, thermoses are made of different materials. Of which? The bulb that is located inside can be made of glass. Thermos food of this kind is primarily hygienic. In addition, the product is easy to clean. After all, food does not stick to the walls of the flask. However, such thermoses have one significant drawback - fragility. One awkward movement can cause the flask to simply crumble into thousands of small fragments.
The thermos container can be made of metal. Usually, materials that are not susceptible to rust are used to create such products. Therefore, in this case you can not worry about corrosion. She will not appear.
Not the best option - plastic flasks. First of all, products made of such a material keep heat very poorly. Of course, mirror spraying can greatly improve the situation. Another disadvantage of such thermoses is fragility. A flask can quickly become unusable if it breaks or crashes.
External housing
Thermos for soup and the second consists of several parts, and each of them can be made of any material. The outer casing may be made of plastic. This material greatly facilitates the weight of the thermos. For many, this moment is very important.
A metal case is much more reliable and stronger, heavier, but more durable. Glass products are rare, as this is not the most practical material.
When choosing a thermos for soup, it is worth considering all of the above nuances. Only in this case you can purchase a quality product.
