Vacuum flasks keep drinks at the ideal temperature

Vacuum flasks are intended for maintaining the temperature of drinks. These innovative containers consist of two layers of metal with a vacuum between them, creating a highly effective insulating barrier. The inner layer of the thermos is usually made of stainless steel, which ensures that the original taste of the drink is preserved without giving it an undesirable taste. The insulating properties of thermoses make it possible to keep hot drinks such as coffee, tea, or soup hot for several hours, even in colder environments. Likewise, they keep cold drinks such as water, juice or iced tea refreshingly cool throughout the day, making them ideal for a variety of outdoor activities and travel.
