Thermos KingHoff KH 4374 0.65 L - double-wall vacuum insulated flask

The KingHoff KH 4374 0.65 L double-wall vacuum insulated flask is a compact stainless steel thermos designed to keep beverages hot or cold while on the move. With a 0.65 litre capacity and a screw-top closure, the flask offers reliable thermal performance in a portable form factor that fits day-to-day use, commuting, travel and outdoor activities. The product combines a vacuum-insulated double wall with a durable stainless steel exterior for everyday wear resistance.

Advantages

The double-wall vacuum insulation reduces heat transfer to preserve beverage temperature for extended periods without the need for external power. Stainless steel construction provides corrosion resistance and impact durability compared with glass alternatives. A screw-top closure ensures a secure seal for transport and helps prevent spills. The flask’s compact dimensions make it convenient to carry in a bag or place on a desk, while the 0.65 L volume balances capacity and portability.

• Keeping coffee, tea or hot drinks warm during commuting and work breaks

How to use

Before first use, rinse the flask with warm water. To maximize temperature retention, preheat with hot water or precool with cold water for a few minutes and then pour out the water before filling with the beverage. Close the screw-top firmly to ensure a tight seal during transport. Pour carefully when drinking directly from the flask or use a separate cup if preferred. After use, wash the interior with warm soapy water, rinse thoroughly and allow to air dry with the lid removed.

Usage recommendations

Do not use in microwave ovens. Avoid dropping or applying strong impacts to maintain the vacuum insulation. For stubborn residues, soak with warm soapy water before cleaning; do not use abrasive cleaners or steel wool. Regularly inspect the screw-top seal for wear and replace if damaged to maintain leak resistance.
