Thermos with Glass Inner Liner Ofenbach 1.0 L Model 101325, double-wall vacuum flask

The Ofenbach thermos with a 1.0 L glass inner liner (double-wall vacuum flask) is designed to maintain beverage temperature for extended periods while preserving flavor neutrality. The internal glass liner resists odor and taste transfer, making it suitable for a variety of hot and cold drinks. The outer vacuum insulation minimizes heat exchange with the environment, and the screw-top closure provides a secure seal for transport and storage.

Advantages

The glass inner liner ensures that beverages retain their original taste and do not absorb metallic or plastic odors. Double-wall vacuum construction improves thermal retention for both hot and cold contents while the external surface remains comfortable to handle. The 1.0 L capacity offers a balance between portability and volume, allowing several servings without frequent refills. The design supports straightforward cleaning of the glass interior and a reliable, leak-resistant closure.

Suitable for

• Carrying tea, coffee or other hot drinks for work, travel, and outdoor activities
• Transporting cold beverages for picnics or sports
• Use in office environments where neutral taste retention is important
• Daily commuting and short trips where a durable, spill-resistant container is needed

Key specifications

• Inner material: glass liner for neutral taste and easy cleaning
• Thermal design: double-wall vacuum insulation for extended temperature retention
• Capacity: 1.0 litre
• Closure: screw-top / leak-resistant cap
• Primary use: transport and temporary storage of hot or cold beverages

How to use

Pre-warm or pre-cool the thermos by rinsing it with hot or cold water before filling to improve temperature retention. Pour beverages carefully into the glass-lined interior, avoiding overfilling; leave a small air gap to allow for expansion of hot liquids. Secure the screw-top cap tightly before carrying. When pouring, open the cap and pour steadily to avoid splashing. Allow hot contents to cool slightly before drinking directly from the thermos to prevent burns.

Usage recommendations

Hand wash the glass liner and cap components with mild detergent and rinse thoroughly. Do not use abrasive cleaners or metal scrubbers to avoid damaging the glass. Avoid sudden thermal shocks (for example, pouring boiling water into a cold liner) to reduce risk of glass damage. Inspect the cap seal periodically for wear and replace if necessary to maintain leak resistance.
