Thermal bottle Adler AD 1381, vacuum insulated flask 0.5 L

The Adler AD 1381 thermal bottle is a 0.5 L vacuum-insulated flask engineered to maintain beverage temperature during daily use. Its double-walled construction with vacuum insulation reduces heat transfer, keeping drinks hot or cold for extended periods. The screw cap design improves spill resistance and the compact 0.5-litre capacity balances portability with sufficient volume for personal use. The bottle’s exterior is smooth and easy to grip, making it suitable for commuting, office environments and short outdoor activities where temperature retention and convenience are required.

Advantages

The vacuum-insulated design minimizes heat loss and condensation, helping hot drinks stay warm and cold drinks remain chilled. A secure screw cap reduces the risk of leaks during transport. The 0.5 L size provides a practical single-person capacity without adding excessive weight or bulk. The bottle’s materials are chosen for durability and routine cleaning, and the compact profile fits most bag compartments and cup holders.

How to use

Before first use, rinse the bottle with warm water. Fill with the desired beverage, close the screw cap securely and store upright in your bag or cup holder. To maximize temperature retention, preheat with hot water or pre-chill with cold water for a few minutes before adding the beverage. Do not overfill—leave some headspace to allow the cap to seal properly. After use, rinse and allow to dry with the cap off to prevent odors.

Usage recommendations

For best performance, hand wash the bottle and cap with mild detergent; avoid abrasive cleaners. Do not use in microwave or freezer. Inspect the sealing components periodically and replace if worn to maintain leak resistance. Use for water, coffee, tea or other non-carbonated drinks; avoid storing perishable beverages for extended periods.
