Thermos NOVEEN TB963 stainless steel vacuum flask 1.5 L

NOVEEN TB963 stainless steel vacuum flask 1.5 L is designed to maintain beverage temperature for extended periods. The flask features vacuum insulation and a corrosion‑resistant stainless steel interior, with a blue exterior and double‑wall construction to reduce heat transfer and preserve taste. Its compact shape and carryable size make it suitable for transport and stationary use in a variety of environments.

Advantages

The double‑wall vacuum insulation minimizes thermal exchange, helping to keep drinks hot or cold for hours. Stainless steel interior and exterior provide corrosion resistance and easy cleaning. Its 1.5 L capacity balances portability with sufficient volume for sharing or extended use. The design reduces condensation on the outside and improves durability compared with single‑wall containers.

Suitable for

• Travel and commuting

How to use

Preheat or precool the flask by filling it with hot or cold water for several minutes, then empty before pouring the beverage to improve temperature retention. Close the lid securely to maintain vacuum performance and limit heat exchange. Pour carefully to avoid spills; when serving, open the cap or pouring mechanism according to the flask’s design. After use, rinse and clean the interior with warm water and mild detergent, and allow to air dry with the lid removed.

Usage recommendations

Do not use the flask for carbonated drinks or perishable, fermenting liquids. Avoid placing the flask in direct flame or on hot cooktops. Clean by hand rather than in a dishwasher to preserve seals and finish. For best thermal performance, avoid filling to the very top and keep the lid closed between pours.
