Which thermos keeps the temperature better?

More and more, such a thing as a thermos is included in everyday life. This fashion came to us from the East, or rather, from Asian countries. Nowadays, many workers not only in heavy professions, such as construction workers, miners and others, but also office workers use it every day.

However, not all models are suitable for maintaining the temperature of hot or cold drinks. For more information on how to choose a truly effective thermos, as well as other nuances of this vast topic, read this article.

The main part of any thermos is a flask that creates a vacuum and, as a result, allows you to keep the temperature. Most of the flasks are made of two materials - a metal alloy and glass. We'll talk about which model of the above keeps the temperature better below.

Despite the special coatings, the metal flask can still rust. Perhaps it is obvious that such a flask will not be light and will add weight to the thermos. The steel flask is especially difficult to maintain. It rusts rather quickly, and small particles of drinks (tea leaves, small pieces of fruit, or something else) stick to it. It is very difficult to wash them off the sides of the flask.

Advantages - it is almost impossible to break such a flask, and metal products do not crack. Such models are suitable for long hikes, hunting trips, fishing and so on. They maintain the temperature of drinks in the cold. Before pouring a hot drink into it, it is advisable to heat a thermos. To do this, you must first rinse it with hot water.

Of the advantages of glass models, it can be noted that they perfectly keep hot water the same for several hours, or even more, even in frost. In general, glass holds heat better than metal. However, the glass bulb is fragile - it can easily crack from careless physical impact or falling. It is better to purchase a similar model for home use.

Glass flasks do not tolerate temperature extremes. Simply put, if an empty thermos was brought from frost to a warm room, and then boiling water was immediately poured into it, then it will most likely crack. On rare occasions, the glass bulb explodes. Models with such flasks weigh less than those with metal ones. The difference is small, but it exists nonetheless. Basically, fans of not only glass flasks, but also glass thermoses, in general, are elderly people.

And there are also plastic models, but they have a low level of ability to maintain temperature. Plastic flasks absorb the odors of the liquids in them. Simply put, after changing the drink, the taste of the previous one will still be felt.

Often, most buyers choose a thermos for reasons of volume and appearance. This is, of course, wrong. The following points will help you make the right choice.

• The quality and appearance of the cover. Before buying, it is imperative to check the tightness of the screw cap. And also it is worth considering the fact that the lid-mug or the lid-dispenser has large slots and does not always fit tightly to the edge. Such a thermos is not suitable for hot tea, although it is very convenient. It is conventionally believed that the simpler the cork, the more reliable it is and will last longer.
• Neck... The narrower it is, the less heat is given off and, therefore, the content cools down more slowly.
• Flask... It is necessary to shake the thermos before buying - the flask should not dangle. It not only does not retain heat, but it will crack quickly. The inner surface of the flask must be smooth and polished.
• Contained fluid volume... Oddly enough, the larger the volume, the longer the heat retention period. Lovers of winter fishing are advised to take 2 liter thermoses, they cool down more slowly. One person usually needs up to 1 liter; a family needs a thermos for 2 liters or more.
• The weight of the product itself. It's no secret that a rare high-quality thermos for hot drinks is lightweight. If a large volume model weighs less than 0.5 kg, then it is better not to take it.
• Protective coatings. Teflon-coated models are more convenient to use - they have no metal smell, and they are also easier to clean.
• Lack of odors. The rare thermos is odorless. Nevertheless, one must take into account the fact that if the thermos has a pronounced smell, then it is better to refuse such a purchase.
• Price range... It is almost impossible to find a good model costing less than 1000 rubles. If the model costs less than this mark, then it is undesirable to purchase it. The exceptions are “bullet” thermoses due to their small size, as well as some thermo mugs. In general, a good model costs 2,000 rubles or more. Obviously, there is no point in purchasing a too expensive model either - it is simply an overpayment.
• Distance between flasks. Everything is simple here - the greater the distance between the flasks, the greater the vacuum. Therefore, the longer the liquid will stay hot or cold.
• Application... In this regard, there are two main types of thermos - for drinks and for food. A distinctive feature of the latter is a wide neck. For drinks, products with a narrow neck are produced, and the thermoses themselves are elongated. There are also universal models, in which you can carry both food and drinks. Their neck is wide. Users note that such models do not keep warm well.
• The presence of a pump. Best suited for small hikes and picnics, and for home use. Better not to purchase these for long hikes.
• For small children, it is better to choose a thermos with a glass bulb. It does not absorb odors and also preserves dairy products well.
• Body material... Of course, it is best to purchase models with a metal case. They are resistant to mechanical damage, and also have a more attractive appearance.

After purchasing a thermos, test it - pour hot water into it and leave for 1 hour. If after this time the body of the product heats up, then its workmanship is low - there is no vacuum, or the air space between the flasks is small. Such a product will not keep warm, and will also gradually heat up itself.

Most of the good reviews are received by American thermos under the brand name STANLEY... Buyers claim that the manufacturer's lifetime warranty is worth it.

Penguin and Amet brands are the most widespread on the domestic market. Users note their availability in case of urgent need to purchase a thermos. Most of domestically produced thermos flasks can twist too much over time. As for the rest, they are in no way inferior to their Western counterparts.
