Vacuum Flask THERMOS Silver 0.5 L, stainless steel insulated bottle, model 8009115040231

THERMOS Silver 0.5 L is a stainless-steel vacuum flask engineered to maintain beverage temperature during daily use. With a 0.5‑litre capacity and vacuum insulation, this insulated bottle is compact enough for commuting, office desks and short outdoor trips. The metal construction and screw-top closure provide a durable, leak-resistant container for hot or cold drinks such as coffee, tea or water.

Advantages

The vacuum insulation minimizes heat transfer to preserve drink temperature for extended periods without external power. Stainless-steel walls resist dents and corrosion and are easy to clean. Its 0.5 L volume balances portability and sufficient liquid capacity for personal use. The slim cylindrical shape fits many cup holders and bag pockets, and the screw cap seals securely to reduce leakage and spillage.

How to use

Preheat or pre-chill the flask by filling it briefly with hot or cold water, then empty before pouring in the desired beverage. Tighten the screw cap after filling to ensure a proper seal. To drink, unscrew the cap and pour into a cup or drink directly if the design allows. After use, rinse with warm water and mild detergent; for thorough cleaning, disassemble cap components if removable and allow all parts to dry completely before reassembly and storage.

Usage recommendations

Do not place the flask in a microwave. Avoid freezing liquids inside the sealed flask to prevent pressure build-up. For best temperature retention, fill the flask close to its capacity and minimize opening frequency. Regularly clean and inspect seals to maintain leak resistance and hygiene.
