Vacuum Flask THERMOS 4067.351.075 — 0.75 L Stainless Steel, Green

THERMOS 4067.351.075 is a 0.75 L vacuum flask made from double-wall stainless steel with a green matte finish. Designed for thermal insulation, the flask keeps beverages hot or cold for extended periods by combining a vacuum layer with stainless steel walls and a tight-sealing lid. The 0.75 L capacity balances portability and volume for daily commuting, office use, hiking and short trips.

Advantages

The double-wall vacuum construction reduces heat transfer and condensation, helping to maintain beverage temperature without external sweating. Stainless steel construction offers durability and corrosion resistance while the BPA-free materials in contact with the drink ensure food-safe storage. The compact 0.75 L size fits many backpack and cup holder configurations, and the screw-top design minimizes accidental spills during transport.

Suitable for

• Keeping coffee or tea hot during commuting and office hours
• Maintaining cold drinks on short outdoor activities like hiking or cycling
• Use as a reusable beverage container for daily routines and travel
• Bringing soups or warm drinks to work or school

When it may not be suitable

This flask is intended for liquid beverages and soups; it may be less convenient for thick or chunky foods that are better suited to wide-mouth containers. While the 0.75 L capacity is practical for many users, those needing larger volumes for multi-person outings or extended trips may require a larger thermos. The matte finish can show scratches over time with heavy rough handling.

How to use

Pre-heat or pre-cool the flask by filling it with hot or cold water for a few minutes and then pouring it out before adding the beverage. Fill the flask without overfilling to allow the lid to close securely. Screw the lid on firmly to reduce heat exchange and prevent leaks during transport. To pour, unscrew the lid and tip the flask; for soups, use a suitable spoon. After use, rinse or wash the flask according to care instructions and allow to dry with the lid removed.

What to consider before purchase

• Required capacity for your typical use (0.75 L)

• Material preferences (stainless steel for durability and taste neutrality)
• Cleaning method and ease of access to the interior

Usage recommendations

For optimal thermal performance, warm the flask with hot water before filling with hot beverages and pre-chill with cold water for cold drinks. Hand wash the lid and body with mild detergent; avoid abrasive cleaners to preserve the matte finish. Store with the lid removed to prevent residual odours.
