A thermos bottle – often referred to as an insulated bottle – minimizes heat exchange with the surroundings and keeps beverages at temperature for extended periods.
The key lies in its double-walled design, typically made of stainless steel or glass. Between these walls is a vacuum, which minimizes heat transfer through conduction and convection. Additionally, the inner surface is often coated with a reflective layer that directs radiant heat back inside.
A well-sealed lid also plays a crucial role. It prevents heat from escaping through air exchange. This way, your tea or coffee stays hot for hours, while cold drinks remain refreshingly cool.
Thanks to this smart insulation technology, the thermos bottle is the perfect solution for on-the-go – whether hiking, at the office, or traveling.
