Characteristics of thermos for drinking, manufacturing materials
Thermos intended for drinking are equipped with a valve or lid-lump. It is enough to press on a special button to pour a drink.
The design of the device allows the liquid to maintain its temperature for a long time. Thermal vessels with a wide hole are designed to maintain the temperature of different products, as well as liquids. The hole helps to establish the thermal balance of products and the environment.
It is better to take a container with a metal or plastic flask on the road. They are less prone to destruction. The glass flask is well washed after the residues of the food and remarkably retains the temperature. It is designed to store products at home, since fragile material during transportation can burst. For traveling, Stanley thermal circle is perfect in this regard.
