How to act in an unusual situation
If this nevertheless happens and you cannot unscrew the plug, do not panic. There are several ways that will help you open the thermos without damaging it.
- Place the thermos under cold water so that it hits the top of the stuck system element. After cooling, the stopper will decrease in volume. It can be easily unscrewed.
- Try to put in some physical effort. This method is also quite effective because the rough surface of the Stanley thermal vessel body provides a reliable grip. Holding the body of the thermos with one hand, you can unscrew the cap with the other.
- An extreme method is to pry the edge of the cork with a knife. This will have to be done so that some air gets into at least the first turn of the thread.
The special design of the plug greatly facilitates the extraction process 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 thermal vessel. Turning the plug 180 degrees will be enough to open the holes.
Both to drain the drink and to open a stuck cork, just a slight turn is enough.
Simpler design
Let's say you only have a 0.5 liter bottle. Wrap it in foil. We put on two down socks or wrap them in a woolen scarf. We put on a black plastic bag and cover it with tape. The result will be a thermos from the “better than nothing” series.
What is needed to make a thermos

- A pair of plastic bottles (0.5 and 1, or 1.5 and 3 liters);
- Aluminium foil;
- Insulation (see above);
- Scotch;
- Scissors;
- Preferably a knife.

- "Thermos" from a flask
If you have a small flask for alcoholic drinks, then in winter it can serve as a good thermos. The volume of such flasks rarely exceeds 250 ml. However, when thirst overcomes, even a glass of water can significantly alleviate your situation.
Pour warm water into the flask, but not boiling water, so as not to get burned. We put it in a shirt or vest pocket with many pockets. We put on a sweater and a winter jacket on top. Thanks to its flat shape, concealed carrying does not pose any particular problems. The water temperature will always be equal to your body temperature, which is very good in the cold season. You won't be able to get warm, but you'll quench your thirst easily.
We found out that making a primitive thermos at home is not so difficult, but such designs are significantly inferior to industrial designs in terms of heat-insulating properties. It is advisable to make them only if it is not possible to purchase a factory product.
Every fisherman in cold weather while fishing dreams of hot tea or coffee to warm up a little, but it often happens that there is no hot water at hand due to the lack of a thermos. In a thermos you can keep not only hot liquid to keep you warm in the cold, but also cold liquid to enjoy cold water in the summer heat. In this article we will talk about how to make a thermos at home, using only available materials.
Recipes
As a rule, a thermos is usually used for long trips or for outdoor recreation. Most often, this container is purchased specifically for brewing tea. Which one to cook is a purely personal matter. The only thing is that in the cold season it is customary to use black varieties, and in the summer – green ones.
A tea ceremony using a thermos also takes place, because there are a huge number of recipes for this brewing method. At first glance, preparing ingredients may seem difficult, but in reality it is not.
Fragrant herbs: lemon balm, thyme, mint, medicinal herbs, lemon, ginger and many other components - all this will be an excellent basis for creating a chic bouquet of aromas that will unfold in a thermos.

It is best to prepare this drink at night.
In a thermos - very healthy and tasty:

- Pour 40-60 g of dry fruits into a container and pour a liter of mild boiling water;
- add 8 tsp. sugar (this amount).
By morning you have a drink ready to drink.
Odor appears
No surprises: foreign odors arise in containers due to the products that are stored in them. Despite the fact that the inner surface of the thermos is made of materials that do not contribute to the accumulation of sediment (glass, stainless steel, etc.), it still forms over time.
A completely new thermos can also smell, which is due to the coating. When leaving the factory, the inner surface of the flask can be treated with a special composition that retains the properties of the coating during long-term storage of the product.
Finally, elementary mold may form in the container. The mechanism of this phenomenon is simple:
- You poured your favorite drink into the thermos;
- We went fishing;
- We came home tired, forgot to wash the thermos and put it in the closet;
- Six months later, when getting ready to go fishing again, we took out a thermos and discovered an unpleasant surprise in the form of a colony of fungal formations with a specific odor.
How to prevent such situations
So that you do not have to resort to extreme measures, you should not leave a thermos with boiling water for a long time. Use the prepared drink as directed within 8-10 hours. And then you will not have problems opening the thermos.
Naturally, before adding new liquid, rinse the thermal vessel thoroughly. Wash the flask and stopper separately. This will prevent its different parts from sticking together. It is worth remembering that the manufacturer prohibits placing some models in the dishwasher. Before using a thermos, carefully read the instructions for it.
Questions, answers and life hacks
To keep a mug or thermal glass warm longer, do not pour too much liquid into it, but do not fill it halfway either.
Remember that after you pour boiling water into the thermal mug and close the lid, a dense layer of steam forms inside, which helps to “maintain” the temperature. After opening the mug for the first time, it begins to cool faster. If you carry coffee in your hand and slowly sip from it, it will cool down sooner than if you carried the mug with the valve closed the entire time. The cooling rate depends on the surrounding temperature. If it’s minus outside, the thermal mug in the outer pocket of the backpack will cool down faster than in the car.
My thermal mug is leaking! What's wrong and can it be fixed?
To prevent the thermal mug from leaking, do not fill it with boiling water to the very top and let it sit for a couple of minutes without a lid. Excess liquid and high temperature create increased pressure in the flask, the plastic parts are deformed, and the mug begins to leak.
I drink tea from a thermal glass, and it smells like yesterday’s coffee. But the glass was clean!
To prevent the thermal glass from bothering you with the smell of metal, plastic or drinks previously poured into it, choose a model with an internal ceramic coating. The aroma of coffee and herbal teas can linger on porous metal and plastic surfaces, adding an undesirable flavor. Another option is to use different utensils for coffee and tea.
I love takeaway coffee, there are several favorite places around the city. Which mug is right for me?
Opt for a low mug if you plan to pour coffee straight from the machine. In addition, you may not need a vacuum mug that holds heat for a long time - the coffee in it will be too hot if you are used to drinking it on the go.
Does the thermal mug keep the cold well?
Typically, thermal mugs keep food and drinks cold longer than hot. Therefore, they can be used as containers for transporting chilled products, such as ice cream.
Is it possible to take a thermal mug on board an airplane?
At pre-flight inspection, the thermal mug must be empty, but you can fill it with your favorite drink before boarding the plane, in a cafe.
Causes
The reason that a thermos (thermal mug) has a tightly screwed lid is a decrease in pressure inside it. Due to this difference, it becomes very difficult to open it. To solve the problem, you need to press the valve in the lid to equalize the pressure and calmly open it.
At the moment when hot liquid is poured into the thermos, the metal thread expands and fits tightly to the base, creating a vacuum. As a result, the lid fits tightly to the thermos, and it becomes very difficult to open it.
Making a plug
Sometimes, when the original mechanism fails, people have a question: how to make a stopper for a thermos with your own hands? For this you will need:
- vice;
- aluminum foil;
- Styrofoam;
- cling film.
The easiest way is to bring an old cork back to life. It is enough to simply steam it, holding it in a vice, and keep it this way until it cools completely. Then you should wrap the plug in foil - this will save it from destruction under the influence of high temperatures.
And to make a new stopper (preferably before making a thermos with your own hands), you will need a piece of foam plastic. An element of the required size and shape is cut out of it, which is covered with cling film to prevent it from falling into the liquid.
If such a plug is pushed out by a thermos, then it will be enough to pierce it through with a syringe needle. It is advisable to make the hole in the center, otherwise the plug may become deformed.

Thermoses are gaining great popularity today, becoming an indispensable attribute in almost every family.
But it happens that the lid of the thermos is tightly screwed on and it becomes almost impossible to open it. We will look at what needs to be done to solve this problem in the article.
Opening methods
Safe and effective methods for opening the lid are to cool or heat it. Using a bottle opener or knife can also help solve this problem, but may damage the thermos.
Method one (under cold water)
This method is suitable for thermoses with external threads. The essence of the method is to place a thermos under cold water to cool. This way the metal thread will begin to narrow, fitting less tightly to the flask, and it will become much easier to unscrew the lid.
To make the thermal mug last longer
- Do not wash vacuum thermal mugs in the dishwasher (except for their lids, as well as models with a special mark).
- Do not pour carbonated or fermented milk drinks into thermal mugs. Do not carry dry ice in a thermos. Do not close the lid immediately after filling the mug with boiling water. All this can cause excess pressure, deformation of parts and leakage.
- Wash the thermal mug immediately after use or as quickly as possible.
- Dry with the neck up, allowing air to circulate.
- Store unassembled or loosely closed to avoid the greenhouse effect.
- Try not to drop the thermal mug.
