Non-slip finish: They are bands that help hold the containers more securely since the plastic used allows a better grip. They are usually smooth, although you can also find them with certain grooves that will provide a pleasant texture to the touch.

Cup style lid: Some thermoses have a lid integrated into the container that becomes a small cup, where you can pour your drink, either hot or cold, and enjoy it anywhere. It is very practical because after using it, you only have to rinse it and place it back on top of the bottle.

Insulation system

Preserving the temperature of a drink depends largely on the material with which the thermos is made. It is common to find those made of plastic, glass, and even ceramic, however, those that maintain the original temperature of the drink for a long time are made of stainless steel.

The system used in a thermos is that of a vacuum between walls. That is, by generating a vacuum between the inner and outer walls of the container, a heat transfer is not allowed. Therefore, the temperature of the liquid lasts longer intact. When you look for one of these products, make sure that it includes this technique.
