A vacuum flask is a container designed to maintain the temperature of liquids by using vacuum insulation technology. The double-walled construction of a vacuum flask creates a layer of insulation between the interior and exterior, minimizing heat transfer and allowing liquids to remain hot or cold for long periods. Vacuum flasks are typically made from stainless steel or glass and are used to carry hot drinks like coffee and tea or cold beverages such as water and juice. They are popular for outdoor activities, office use, and daily hydration due to their effectiveness and durability.
