Thermos KingHoff KH 4054 – metal vacuum flask 1000 ml, double-walled insulated

KingHoff KH 4054 is a metal vacuum flask with a 1000 ml capacity engineered to maintain beverage temperature over extended periods. The double-walled insulated construction and metal body offer improved thermal retention for hot or cold drinks. The flask features a screw-top closure combined with an automatic stopper and pourer for one-handed pouring without fully removing the lid. Dimensions are approximately 25 x 8 cm and the product includes a removable cover for transport and protection.

Advantages

The double-walled vacuum design reduces heat transfer, helping to keep liquids hot or cold for many hours. A durable metal exterior resists dents and daily wear while the included cover provides extra protection and grip. The automatic stopper with pourer streamlines pouring and reduces spills, and the screw-top closure ensures a secure seal to minimise leakage during transport. With a 1000 ml capacity, the flask accommodates multi-serving portions for travel or shared use.

Suitable for

• Commuting and daily work use
• Outdoor activities such as hiking, picnics, and camping
• Long drives and travel where temperature retention is needed
• Home use when a large quantity of hot or cold beverage is required

How to use

Before first use, wash the flask, lid and stopper with warm soapy water and rinse thoroughly. Pre-warm or pre-chill the flask by filling it with hot or cold water for a few minutes, then empty and pour in the beverage to improve temperature retention. Use the automatic stopper and pourer to serve liquids without fully removing the lid; press or release the stopper mechanism as designed to pour. After use, rinse or wash the interior and allow all parts to dry with the lid removed to prevent odours.

Usage recommendations

Do not put the flask in a microwave. Avoid dropping or striking the flask to maintain vacuum performance. For long-term preservation of thermal efficiency, hand wash components rather than using a dishwasher and avoid abrasive cleaners that could damage seals or external finish.
