Metal thermoses: features, recommendations for choosing and using

Thermos is an indispensable thing when traveling and hiking, on vacation and at work. To date, the range of thermoses is very wide. All products differ in properties, materials of manufacture, features and characteristics. The most popular model is a metal thermos. This cookware has thermal insulation properties. By production of a flask stainless steel is used. Its properties contribute to the preservation of temperature: hot drinks stay hot in it for a long time, cold drinks stay cold.

The inside of the flask is covered with food steel with anti-corrosion coating, which prevents oxidation and release of harmful substances. The outer side has a special coating. It enhances heat transfer. The vacuum layer between the two walls does not conduct warm air, so keeping the temperature of the drink is possible up to 33 hours.

The thermos has a narrow neck. It closes with a tight lid, which helps to keep the heat inside. There are channels on the lid with which you can pour drinks from a half-open thermos. This method reduces the risk of getting burned and is safe to use when hiking.There is a sealing ring on the cork, thanks to which the lid fits snugly to the body. The presence of the ring also prevents the penetration of cold air inside.

The thermos comes with an extra plastic cup. The lid of the thermos can also be used as a cup and enjoy the taste of the drink together. The stainless steel thermos is covered with a special fine-grained layer, which prevents hands from sliding on it and prevents the skin from freezing to the thermos in the cold. Moreover, this coverage shock and deformation resistant.

Thermoses made of metal come in several types.

Before choosing a thermos, you should decide for what and where it will be used. For long trips and hikes, you need to choose a product with a larger volume. For walks in the park and in nature, it is enough to have a product with a volume of 0.5 to 1 liter. When choosing a thermos for a picnic, a thermos with a glass flask with a capacity of up to 3 liters is suitable.

Important nuances:

• the large capacity of the container maintains the temperature longer;
• the temperature of food and drinks depends on the consistency of the product: liquids retain heat longer;
• to maintain the temperature for 3-6 hours, a thermos with a volume of 0.5 l is suitable;
• when choosing a thermos, it is necessary to shake the product and check for the absence of foreign odors, and if the flask dangles and has a chemical smell, the thermos should not be bought;
• when buying in a store, you must make sure that there is a quality standard stamp on the case.

The device must be washed before the first use. To do this, all parts are removed and thoroughly washed separately.In order to clean the thermos, you must use soda and detergents. After washing, it is necessary to collect the product and dry well. Do not wash the thermos in the dishwasher. The thermos is intended for storage of cold and hot drinks, broths and second courses.

It is forbidden to store ice, fermented milk products and drinks, baby food, soda in the product. Do not heat the appliance in an open flame, in a microwave oven or in any other way. There should be a distance of 1 cm between the thermos lid and the poured drink.

It is recommended to wash the product after each use. In case of severe contamination, it is necessary to fill the container with water and detergent and leave for a while, then rinse with running water. Before each use, the dishes must be warmed up. To do this, pour a little boiling water into a thermos and let stand for a couple of minutes. After a while, drain the hot water and fill the container with a drink. This recommendation will help extend the heat preservation of tea or coffee for 3 hours longer.
