When choosing a thermos, you should pay attention to four features: vacuum, size, smell, stopper.
In thermoses, heat is kept by a vacuum. It is located between the double wall of the thermos, and the greater the distance between the walls, the better. The narrower the neck of the thermos and the larger the volume of the thermos, the longer you will drink a hot drink.
The size of the thermos depends on the purposes for which you buy it. A thermos with a wide mouth and a universal stopper is suitable for the home. For trips, a large thermos will help, but if the trip is short, choose a light and compact one. For work - a thermal mug and a food mug, but it is better to take a universal one for 1-1,5 liters.
A sharp and unpleasant smell from a new thermos indicates that it is made of low-quality material.
The cork can be metal, glass or plastic. Metal is strong, keeps the temperature, but has a lot of weight and is more difficult to wash. Glass is the best for storing products, it is easy to clean, but it is unreliable because it can crack and break.
Plastic - absorbs various odors very well and retains them, but it is light and easy to clean.
Using our advice, you will purchase a thing that will serve you for a long time and reliably!
