Thermal water bottle or vacuum flask.
It is designed to keep beverages hot or cold for extended periods, typically 6-12 hours or more, due to its double-walled, vacuum-insulated construction.
The bottle is made of food-grade stainless steel, often 18/8 or 304, and is BPA-free.
It features a one-click opening mechanism with a spout lid, making it convenient for drinking and preventing leaks.
This type of bottle is suitable for carrying hot or cold drinks like coffee, tea, or water while traveling or on the go.
