Thermos are an essential companion for many people who want to keep their drinks hot or cold for a long time.
The thermos flask, originally known as the vacuum flask, was invented in 1892 by Scottish scientist Sir James Dewar. Dewar, who specialized in cryogenics, created the vacuum flask to keep the temperature of liquid gases stable. This invention involved placing one glass container inside another and creating a partial vacuum between their walls, minimizing heat transfer.
Materials of thermoses
Coffee and tea thermoses can be made from a variety of materials including glass, metal and plastic. Glass thermoses are popular for their excellent insulating properties, but are fragile. Metal thermoses, often made of stainless steel, are more durable and suitable for harsher conditions.
Developments in materials and technology have led to significant improvements in the properties of thermoses. In addition to the traditional glass liners, stainless steel is increasingly being used as it is more resistant to impact and corrosion. Stainless steel thermoses are also often double-walled, which means that there is a vacuum between the two layers of steel, providing exceptional thermal insulation.
For maximum efficiency, we recommend that you pre-heat the thermos with warm water before filling it with a hot beverage and, conversely, cool it with cold water for cold beverages.
Thermoses should be cleaned regularly to prevent the accumulation of deposits and odours. To clean, use a soft brush and a mixture of water and vinegar or baking soda.
With the growing emphasis on environmental protection, thermoses have become a popular alternative to disposable plastic bottles and cups. Reusable coffee or tea thermoses reduce plastic waste and promote sustainable living habits.
