Vacuum Flask THERMOS 4067301100, 1 L, Stainless Steel, Burgundy

THERMOS 4067301100 is a 1 L vacuum flask with a stainless-steel housing in burgundy finish. The double-walled insulated design reduces heat transfer to keep hot drinks warm and cold drinks cool for extended periods. The flask features a wide opening for easy filling and cleaning and a leak-resistant lid that makes it suitable for carrying in a bag or for use outdoors, at the office or while travelling.

Advantages

The double-walled vacuum construction provides reliable thermal insulation without external condensation. Stainless-steel construction offers durability and resistance to impacts and daily wear. The wide mouth simplifies pouring, adding ice and cleaning. A leak-resistant closure helps prevent spills during transport. The 1 L capacity balances portability with enough volume for multiple servings.

Suitable for

• Keeping coffee or tea hot during a workday or commute
• Maintaining chilled water or soft drinks on hikes and outdoor activities
• Use in offices, vehicles, picnics or travel where temperature retention is needed
• Refilling at home before leaving for a day trip or long meeting

When it may not be suitable

This vacuum flask is not intended for long-term storage of highly perishable liquids that require refrigeration beyond typical beverage temperature control. It is also not designed for use with carbonated beverages where pressure build-up could occur. Very narrow spaces or cup holders designed for smaller bottles may not accommodate the 1 L size.

Key specifications

• Capacity: 1 litre
• Material: stainless-steel body with insulated double-wall construction
• Finish: burgundy exterior
• Opening: wide mouth for filling and cleaning
• Closure: leak-resistant lid
• Intended use: hot and cold beverages

How to use

Preheat or pre-chill the flask by rinsing with hot or cold water before filling to improve temperature retention. Fill with the desired beverage, secure the lid firmly to ensure the leak-resistant seal, and carry as needed. For best thermal performance, avoid frequent opening. Clean the wide mouth and interior with warm soapy water and a bottle brush; allow to dry completely before storing. Do not use in microwave ovens.

What to consider before purchase

• Confirm that a 1 L capacity fits intended daily or travel needs and available cup holder or storage space
• Consider whether a stainless-steel exterior and burgundy finish match your usage and care preferences
• Check whether you need a flask compatible with carbonated drinks (this model is not recommended for carbonated beverages)

Usage recommendations

To maximize temperature retention, pre-warm with hot water for several minutes before filling with a hot beverage, or pre-chill with cold water or ice before adding cold drinks. Secure the lid after each fill and clean the interior regularly to maintain hygiene and performance.
