A thermosome is a special vessel in which a certain temperature is maintained. It is used to store food, liquids in hot or cold condition. It is compact and mobile. The main components of the product are the flask and the inner container.
Basic thermos selection options
Purchasing a product begins with determining the purpose for which it will be needed. If the model is needed for use in a home environment, then it is better to purchase a product of large volume, with the presence of a universal cork and a wide neck.
For hiking or picnics the model is lightweight and compact. Let us consider in more detail each of the characteristics:
Volume of liters
Modern manufacturers offer a wide variety of displacement models. There are small models, the volume of which is 0.25, there are also options for industrial use 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 thermomugs.
- The standard option is 1 - 2 liters, this is a universal model that you can take with you, it fits comfortably in a backpack;
Large capacity thermoses have a volume from 3 liters, for large companies.
Important: Checking the performance of the product is carried out at home. To do this, boiling water is poured into the thermos for about two hours, after which the condition of the case of the model is checked. The outside should be cold and the contents of the thermos hot, as if it had just been poured.
This element of the vessel is made of stainless steel or plastic. Metal has advantages over plastic in terms of resistance to external influences; therefore, such a product can be easily transported without worrying about the integrity of the thermos.
This is an important detail in the design of the thermos. One of three material options is performed - stainless steel, plastic and glass.
Stainless steel flask has a high level of strengthholds well the temperature inside the product. Among the minuses can be noted sufficient weight and complex care of the inner part, as food or liquid residues adhere tightly to the metal.
The plastic version of the part is much lighter than the metal one; it is quite resistant to external influences, for example, drops. A significant disadvantage of this material is the good absorbency of odors that are released when exposed to temperature.
Glass bulb 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, take the product in your hands and shake. If there is a rattling sound inside the thermos, it is better to refuse the acquisition.
Which thermos is better: with a glass flask or metal
This question is often of interest to consumers. The advantages of a glass bulb in good performance are excellent in keeping heat, and are easy to clean. But they are very fragile, so the use of a thermos it is impossible to go with a glass bulb on hikes - this is an exclusively household appliance for home use.
As for the metal flask, it is shock resistantbut keeps heat a little worse, and particles of food or tea remain on the metal. But such a product is ideal for tourism. Based on the facts, the choice of the best option depends on the scope of the product.
Popma (trigger valve)
Manufacturers of modern models equip a thermos with a special pump. This is usually a small thermos with a pneumatic pump. It is activated by pressing the lever-key. In more expensive models, there is a dispenser, through which a certain volume of the poured liquid is set at a time. Such a thermos holds up to 3 liters, it is important to know that the larger the volume of the product, the slower the water cools in it.
