How to open a thermos with hot water. Why does the thermos heat up? Ginger tea in a thermos

The days when a thermos was exclusively an attribute of a tourist are long gone. Healthy food and homemade meals are all the rage today. Hot, preferably. Microwaves are considered by many to be harmful or simply disdain to use them at work. In this regard, thermoses do not lose their relevance. You can put both the first and the second, and hot compote in them. AiF.ru tells what models are on the market and how to use them correctly.

Material

The body of thermoses is made of plastic or metal. The former are lighter, suitable for daily use, the latter will cost more, but will last longer and withstand falls and bumps.

The main task of a thermos is to keep the temperature. The flask is responsible for this. Glass works best, and besides, it is resistant to odors. However, for an active lifestyle, such a flask is not suitable - it is too fragile. A flask made of stainless or ordinary steel is almost as good as a glass flask in keeping warm, while at the same time it will last longer. A thermos with a plastic flask is the cheapest option, it weighs little, but actively absorbs odors and releases them when heated.

Form and purpose

Thermos for liquids intended for transportation of ready-made drinks: tea, coffee, water, compote, broth. However, it is not suitable for storing soda, it is not advised to use it for brine, dairy products and infant formula. Such a thermos usually has a narrow neck (25-60 mm), which also contributes to a longer preservation of the temperature of the liquid. Often these thermoses are equipped with a valve that allows you to pour a drink without unscrewing the cap. The lid can be used as a glass.

Pump thermos also used for liquids, but differs from the conventional model by the presence of a pneumatic pump and a valve. Press the button on top, the drink pours from the tap. Keeps the temperature of the liquid throughout the day. But it has large dimensions - at least 1.5 liters. Therefore, it is not suitable for carrying, it is only suitable for stationary use.

Thermo mug... Differs in a compact form (250-500 ml), which is convenient for use in the car, gym, work or study. They usually have a plastic lid with a plug that allows drinking directly from a thermos, as well as a handle or rubberized area on the body. The main disadvantage of the thermo mug is that it is not designed for long-term storage of the contents, but keeps the temperature only during the consumption of the drink, for a maximum of 2 hours.

Food thermos used for storing first and second courses. It has a wide neck (65-80 mm), it is convenient to put and take food out of it. However, the large hole diameter reduces the shelf life of food to 4-6 hours. Food thermoses have a single-level design that allows you to carry one dish, or multi-level, the so-called vessel thermoses. Such a model consists of several, usually three, independent containers fastened together. Each of them is airtight, which allows you to take several ready-made meals to work or on the road at once.

Universal thermos- the most popular model, which is suitable for transporting both liquids and ready meals. It has a special double cork structure. If you unscrew it completely, then a wide throat is formed, suitable for eating, and if only the inner part, then there will be a narrow hole needed for drinks. The way the thermos is used affects the temperature retention time, up to a maximum of 8 hours. Such models are usually equipped with sturdy handles and folding appliances.

How to choose

We have decided on the model. But choosing a thermos requires careful attention. In the store, be sure to shake the thermos. If there is sound and rattling, then it will keep the temperature.

Check if the plug closes tightly, if it fits well.

Unscrew the plug and sniff. It is important to make sure that there are no foreign odors.

Fill a thermos with boiling water. You need to check if the temperature changes after a few minutes.

How to use?

When using a thermos, you should be careful not to let it fall and hit, especially if the body and the flask are made of fragile materials.

It is recommended to fill the thermos completely to keep food and drinks at a temperature longer. However, this should leave room for the flask and a little more empty space so as not to burn yourself when opening.

Do not heat the flask in the microwave or oven.

You cannot leave food and drinks in a thermos for a long time, maximum - two days.

For washing, you need to use a soapy solution, not abrasive products, so as not to damage the surface.

To avoid smell, the thermos should be dried disassembled, and the empty thermos should be stored with a loosely closed lid.

To get rid of the unpleasant smell will help boiling water poured in for half an hour with diluted soda.

Where does the hot stay hot and the cold cold? In a thermos, of course. This useful item is now available in almost every family. It is truly indispensable not only for summer residents and lovers of long walks in cold weather, but also for those who prefer to take home lunch to work rather than eat in a local canteen. Indeed, it is very convenient, because modern thermoses have different sizes and shapes, and in them you can successfully keep hot not only tea or coffee, but also soup or aromatic vegetable stew. And in the summer heat, any drink in a thermos will remain cool and refreshing for a long time.

And now you have purchased this wonderful device and are rubbing your hands in anticipation of daily hot meals instead of disgusting pies from the nearest eatery. But do not rush to immediately pour lovingly cooked borscht into a freshly purchased thermos. For a start, you should familiarize yourself with the simple thermos operating rules... Yes, yes, do not rush to dismiss the instructions in the cardboard box with irritation. It is possible that you will discover a lot of interesting knowledge that will help you extend the life of your thermos. Otherwise, do not be surprised that even an expensive thermos, advertised as high quality and reliable, will lose its functions in a couple of weeks. In fact, a lot depends on compliance with the operating rules: both your safety when using a thermos, and its durability, and how well it will cope with its main task - maintaining the temperature of the contents. Let's try to highlight the main points to which you should pay attention.

First use: open, pour, cork?

Of course no. First of all, a newly purchased thermos is necessary wash thoroughly... Do you wash your vegetables and fruits after purchasing? As our mothers and grandmothers used to say, “you never know where it was lying!”. In fact, traces of factory grease and trivial dust may remain inside the thermos. Rinse the inside of the thermos with warm water. You can use baking soda, laundry soap, or any non-corrosive dishwashing detergent. Proper cleaning of the thermos will not only protect you from germs, but also get rid of unpleasant odors. Before washing, be sure to disassemble the thermos and rinse each part separately, and then dry thoroughly. Now your brand new thermos is ready to serve.

Before pouring hot water into the thermos, hold the hot water in the flask for three minutes. This will help prepare it to maintain the correct temperature. Do the same with cold water if you want to keep your drinks cool. But remember to use a microwave or oven to heat the flask. absolutely not.

Pouring liquid into a thermos, do not fill the flask to the very brim... Remember to plug it with a cork, which will require a little space. Close the stopper carefully so that the contents do not spill.

How to extend the life of a thermos?

How does the thermos keep the temperature? Due to perfect thermal insulation. It consists of two metal flasks with a vacuum between them. Any seemingly insignificant scratch or crack on the body of the thermos can disrupt the thermal insulation, which means that the thermos will lose its main function. Despite the fact that any high-quality stainless steel thermos is quite durable, try to avoid accidental mechanical damage... However, it will easily survive falls from a low height, but extra accuracy never hurts.

It is necessary to rinse the thermos after each use.... It is best to do it right away, but of course, such an opportunity is not always available. If traces of food or drink have firmly settled on the walls of the flask, fill it with warm water and leave to soak overnight. Now you shouldn't use an abrasive washcloth - you can damage the flask. In the morning, you can easily wash off the dirt with any detergent. If you do not rinse the thermos in time, it will be difficult to get rid of the unpleasant smell later. If you are used to using a dishwasher, you still have to wash the flask manually - this is another safety rule.

It is recommended to store the thermos between uses with the lid open to avoid the appearance of an unpleasant odor. And if the smell does appear, it can be removed with regular baking soda. Fill the flask with warm water, add soda and leave for several hours, then rinse with warm water and dry thoroughly.

What can and cannot be stored in a thermos?

Many people like to drink cold soda on a hot summer day ... but we hasten to upset you: pouring carbonated water into a thermos is absolutely impossible... This prohibition has a very simple explanation. Carbon dioxide in soda can react with the metal the flask is made of. This will almost inevitably damage the thermos. Cannot be carried in flask and dry ice which will give the same disastrous result. Not recommended use a thermos for storing dairy products and diluted infant formula.

But you can pour clean drinking water, tea, coffee, soup or broth into a thermos. The second course will perfectly fit in, which will become a pleasant lunch at the workplace or a hot snack in nature.

Supplied with a secure plug. It is designed to maintain the maximum temperature of the liquid, even when draining from a thermos into a cup. With these thermoses, there are practically no such troubles as a tightly twisted lid.

Reasons why the cover may be difficult to unscrew

This is possible if you pour boiling water into a thermos and, having tightly tightened the cork, leave it unattended for several days. This almost never happens. According to statistics, the contents of a liter thermal container are drunk in the next 8 hours after the liquid is poured into it. But the circumstances may be different. The company's developers have thought of such a rather unlikely option.

As a liquid cools, as is known, it decreases in volume. Its decrease in the closed space of the flask invariably leads to a decrease in pressure. The plug is literally pushed inward by the difference between external and internal pressure.

The presence of threads counteracts this. If a plug without a thread can firmly bite into the walls of the neck, then the threaded model will only go a little deeper into it.

Another reason for an unpleasant situation may be the elementary adhesion of surfaces to each other. This can happen if you stored very sweet tea in a thermos, and then, after rinsing it poorly, poured another liquid. Under the influence of high temperature, sugar microparticles will melt between the contacting surfaces. As they cool, they become viscous. This contributes to the sticking of different parts of the thermos.

If this, nevertheless, happened, and you cannot unscrew the plug, do not panic. There are several ways to help you open the thermos without damaging it.


The special design of the plug makes the extraction process much easier even in such a situation. The fact is that there are through holes inside it. In order to pour liquid, there is no need to completely unscrew the thermos container. Turning the plug 180 degrees will be enough to keep the holes open.

Both to drain the drink and to open the jammed cork, just a slight twist is enough.

How to prevent such situations

So that you do not have to resort to extreme measures, do not leave a thermos with boiling water for a long time. Use the prepared drink as directed within 8-10 hours. And then you won't have any problems opening the thermos.

Naturally, rinse the jar thoroughly before pouring in new liquid. Wash the flask and stopper separately. This will prevent the different parts from sticking together. It should be remembered that the manufacturer prohibits putting some models in the dishwasher. Before using the thermos, carefully read the instructions for it.

If you want to extend the life of the thermos, and also if you have a desire to increase the time it retains the temperature inside during operation, then, using our advice in practice, you can achieve this. At the same time, you don't have to put in much effort.

How to keep the temperature in a thermos for a longer period

As a result of the natural transfer of some of the heat from food or liquid to the flask, the temperature of the product itself (or drink) decreases. Thus, by preheating the flask, you can increase the heat retention time in the product placed in it. This can be done quite simply: boil water and pour it into. Keep the water inside the container for about 30-40 minutes, after which you can pour it out. This time is quite enough for the flask to warm up well and not take heat energy from food or drink that will be placed in it.

Please note that if the temperature difference is large, the glass bulb may burst due to expansion. Therefore, before pouring boiling water into a cold thermos, it is advisable to first let it warm up to room temperature. This process can be accelerated with warm water (not boiling water). Remember also that liquids or foods should not be hotter than 100 ° C. This is, in particular, about oil. Such products need to be kept for some time so that they cool slightly. Otherwise, either deformation or destruction of the glass bulb may occur.

In the event that you use thermal dishes for storing cold food or drinks, on the contrary, you need to cool the flask with small pieces of ice or cold water. And the violation of thermal conductivity or the appearance of cracks when exposed to cold on a heated glass flask (for example, if you rinsed it with boiling water) can also be avoided by reducing the temperature contrast, that is, letting the thermos cool down.

Neatness and neatness again!

Glass bulbs are very fragile. And no matter what manufacturers say that today's thermoses with such flasks are more impact-resistant than their ancestors, they still cannot be compared with thermal dishes, inside which there is a steel container. In addition to the fact that the thermos will lose its functionality when the flask is broken, it can be a source of danger due to small fragments remaining in the sealed gasket. So you shouldn't use this thermos. Although, if you manage to replace his flask, then you can give him a second life.

All-steel thermoses are several times superior to their counterparts described above in terms of strength and resistance to damage and deformation. Therefore, some manufacturers give them a lifetime warranty. But this does not mean that they (thermoses) cannot be spoiled. Any indentation changes the configuration of the internal space between the body and the steel bulb, which cannot but affect the thermal insulation characteristics. And a strong blow to the soldering in the place of the connecting seams can generally lead to depressurization of the thermos. And even if you try to repair this thermal cookware, it will no longer demonstrate the same heat storage performance. Therefore, remember to handle thermos flasks with care and try not to drop them.

Even children know that a thermos is a device for keeping the right temperature for a long time. But only a quality product can boast of such properties. To acquire an excellent invention that is designed to make our lives easier, you need to know how to choose it and handle it in the future.

By the way, speaking of inventions, the brainchild of the Englishman James Dewar Deward became the prototype of the modern accessory. From a glass container, he built something like a bottle with double walls, between which he pumped out air, applied a silver layer to the surface and got a wonderful item for storing rarefied gases. It was only after many years that his student set up the production of thermoses for household use.

Today we can purchase thermoses for a variety of purposes, which are united by one mission - to keep the contents warm or cold. A thermos for tea is the most demanded category of goods in this segment and it is about it that we will be talking about.

The best thermoses for tea and coffee: how to choose?

A thermos is a structure consisting of an inner flask and an outer casing, which are separated by a vacuum space. Therefore, these two components are decisive when choosing a container for a liquid.

  1. A glass flask holds the temperature well, but breaks very easily. These types are more often bought for making tea at home;
  2. The metal bulb gives off cold or heat rather, but it is shock-resistant. These thermos flasks are great for hiking and travel.
