Vacuum Bottle

A vacuum bottle, also known as a thermos, is a container designed to keep liquids hot or cold for extended periods of time. The bottle is made of two layers of glass or stainless steel with a vacuum between them, which prevents heat transfer through conduction and convection. The vacuum bottle also has a tightly sealed lid, preventing air from entering or escaping, which further contributes to its insulating properties. Vacuum bottles are commonly used for outdoor activities, picnics, camping trips, and for transporting hot or cold beverages to work or school. They come in various sizes and designs and have become a popular choice for environmentally conscious consumers looking to reduce their use of single-use plastics.
