Vacuum Flask Thermos 4067341100 1 L Blue, Stainless Steel Housing

Thermos 4067341100 1 L Vacuum Flask in blue with a stainless steel housing is designed to keep hot drinks hot and cold drinks cold while on the move. The vacuum-insulated, double-wall construction reduces heat transfer and helps maintain beverage temperature for several hours. The 1-litre volume and screw-top lid make it suitable for daily use, commuting, picnics and outdoor activities where reliable thermal retention and a durable exterior are required.

Advantages

The stainless steel housing provides impact resistance and a matte blue finish for a clean look that resists scratches. Double-wall vacuum insulation delivers effective thermal performance for both hot and cold liquids. A one-litre capacity balances refill frequency and portability, and the screw-top closure minimizes spillage while aiding heat retention. The design is practical for repeated use and easy to clean.

Suitable for

• Carrying hot coffee, tea or soup during commuting or travel
• Keeping water, juice or cold drinks chilled on outdoor trips and picnics
• Use at the workplace, on construction sites or during sports breaks
• Long day trips where a larger single-container beverage supply is required

When it may not be suitable

This vacuum flask is not intended for long-term storage of perishable liquids; it is designed for short- to medium-term temperature retention during transport and everyday use. If you need a container with an integrated cup, hands-free drinking spout, or insulated storage for multi-day preservation, consider alternative models that provide those specific features.

Key specifications

• Capacity: 1 litre
• Material: stainless steel exterior and likely stainless inner lining for vacuum flasks
• Construction: double-wall vacuum insulated
• Finish: matte blue exterior
• Closure: screw-top lid to reduce spills and improve insulation
• Typical use: suitable for hot and cold beverages

How to use

Preheat or precool the flask by rinsing with hot or cold water for a few minutes before filling to improve temperature retention. Unscrew the lid, pour in the desired beverage leaving a small air gap at the top, then securely tighten the lid. Open the screw-top slowly to pour or drink to prevent pressure-related splashes. After use, disassemble the lid if possible and clean with warm, soapy water; avoid abrasive cleaners to protect the matte finish. Allow all parts to dry fully before reassembly and storage.

What to consider before purchase

• Confirm that a 1-litre capacity fits your daily needs and carrying options
• Check that a screw-top lid meets your convenience and pouring preferences
• Consider weight when filled and whether the stainless steel housing is acceptable for your activities
• Decide if you need additional features such as a cup, car cup-holder compatibility, or a carrying handle

Usage recommendations

For best thermal performance, precondition the flask with hot or cold water before filling and avoid frequent opening. Clean and dry thoroughly after each use to preserve the stainless steel exterior and maintain hygiene.
