How to choose a thermos

A thermos is a special vessel in which a certain temperature is maintained. It is used to store food and liquids in a hot or cold state. It is compact and portable. The main components of the product are the flask and the inner container.

Basic parameters for choosing a thermos

Purchasing a product begins with determining the purpose for which it will be needed. If the model is needed for use at home, then it is better to purchase a large-volume product with a universal stopper and a wide neck.

For hiking or picnics A light and compact model is better suited. Let's take a closer look at each of the characteristics:

Volume liters

Modern manufacturers offer a wide variety of models by displacement. There are small models with a volume of 0.25, and there are also industrial options up to 40 liters, they are called thermal containers. Models are divided into several categories:

• Small displacement is 0.2 - 1 liter. These models are called thermal mugs.
• Standard option – 1 – 2 liters, this is a universal model that you can take with you, it easily fits into a backpack;

Large thermoses have a volume from 3 liters, for large companies.

Important: The product's functionality is checked at home. To do this, boiling water is poured into the thermos for approximately two hours, after which the condition of the model’s body is checked. The outside should be cold, and the contents of the thermos should be hot, as if it had just been filled.

Thermos body

This element of the vessel is made of stainless steel or plastic. Metal has advantages over plastic in terms of resistance to external influences, so such a product can be easily transported without worrying about the integrity of the thermos.

Flask

This is an important detail in the design of a thermos. Available in one of three material options: stainless steel, plastic and glass.

The stainless steel flask has a high level of strength, holds the temperature inside the product well. Among the disadvantages, one can note the sufficient weight and difficult care of the interior, since food or liquid residues stick tightly to the metal.

The plastic version of the part is much lighter than the metal one, and it is quite resistant to external influences, such as falls. A significant disadvantage of this material is its good absorption of odors that are released under the influence of temperature.

The glass flask is fragile and not suitable for travel. But it holds the temperature well and preserves the beneficial properties of the products.

It is important to know: Before purchasing a product, it is advisable to check the thermos for its integrity. To do this, you need to pick up the product and shake it.If there is a rattling sound inside the thermos, it is better to refuse the purchase.

Which thermos is better: with a glass flask or a metal one?

This question often interests consumers. The advantages of glass flasks are good performance characteristics, they retain heat well and are easy to clean. But they are very fragile, so using a thermos It is impossible to travel with a glass flask - this is exclusively a household appliance for home use.

As for the metal flask, it is shock resistant, but it holds heat a little worse, and particles of food or tea remain on the metal. But this product is ideal for tourism. Based on the facts, choosing the best option depends on the application of the product.

Popma (release valve)

Manufacturers of modern models equip thermoses with a special pump. This is usually a small thermos with pneumatic pump. It is activated by pressing the lever-key. More expensive models have a dispenser, through which a certain volume of liquid is set at a time. This thermos holds up to 3 liters; it is important to know that the larger the volume of the product, the slower the water in it cools.
