Vacuum flask Room Copenhagen 0.725 L — insulated bottle, blue

Room Copenhagen vacuum flask with a 0.725 L capacity in blue is an insulated bottle designed to maintain beverage temperature for extended periods. The flask combines a compact shape with a screw cap and a durable exterior, making it suitable for everyday use, commuting, outdoor activities and kitchen storage. The 0.725‑liter volume provides enough capacity for multiple servings while remaining convenient to carry in a backpack or bag.

Advantages

The double‑walled vacuum construction reduces heat transfer to keep drinks hot or cold longer than a single‑walled container. The screw cap provides a secure closure to prevent leaks and helps preserve temperature. The exterior finish resists everyday wear and is easy to clean. The compact 0.725 L size balances capacity and portability for daily use.

How to use

Preheat or precool the flask by filling it with hot or cold water for a few minutes, then empty before adding your beverage to improve temperature retention. Fill the bottle, secure the screw cap by turning until closed, and place it in a bag or cup holder as needed. To pour, unscrew the cap and tilt the flask; tighten the cap after use to maintain insulation and prevent spills.

Usage recommendations

Hand wash recommended for the interior and cap to preserve the insulation performance and exterior finish. Avoid using abrasive cleaners or scouring pads on the outer surface. Do not place the flask in the microwave. For best results with hot drinks, preheat the flask; for cold drinks, prechill it. Inspect seals periodically and replace if damaged to maintain leak resistance.
