Vacuum flask THERMOS 4067.301.050 0.5 L — stainless steel, burgundy

THERMOS 4067.301.050 is a 0.5 L vacuum flask with a stainless steel housing in burgundy. The double-walled insulated bottle preserves beverage temperature for prolonged periods and is BPA-free. Compact and portable, it suits daily use, commuting, outdoor activities and office use for hot or cold drinks.

Advantages

The stainless steel construction offers durability and corrosion resistance while the vacuum-insulated, double-wall design reduces heat transfer to maintain drink temperature. The 0.5 L capacity balances volume and portability for single-person use. The burgundy finish provides a neutral, practical appearance suitable for various environments. Materials in contact with the liquid are BPA-free, and the lid design reduces spills during transport.

Suitable for

• Commuting and travel
• Office and work breaks
• Outdoor activities such as hiking or picnics
• Everyday home use for hot coffee, tea or cold beverages

When it may not be suitable

This 0.5 L vacuum flask may be unsuitable when larger group servings or extended multi-day trips require higher capacity containers. It is not designed for use with carbonated drinks that can build pressure in a sealed container. The flask's finish may show scratches if subjected to rough handling.

Key specifications

• Capacity: 0.5 litre
• Body material: stainless steel (double-walled, vacuum insulated)
• Color/finish: burgundy
• Intended contents: hot or cold beverages
• BPA-free components in contact with liquids
• Portable size suitable for cup holders and backpacks

How to use

Preheat or precool the flask by filling it briefly with hot or cold water and discarding before adding your beverage to improve temperature retention. Secure the lid tightly to reduce heat loss and prevent spills. To pour, open the lid according to the cap mechanism and pour directly into a cup or drink from the spout if the design allows. Allow the flask to return to room temperature before opening if it contains very hot liquid to avoid scalding.

What to consider before purchase

• Required capacity for daily needs (0.5 L)
• Compatibility with cup holders or backpack pockets
• Preference for stainless steel and burgundy finish
• Intended beverage types (avoid carbonated drinks)

Usage recommendations

Clean the flask before first use and wash regularly by hand using warm soapy water; avoid abrasive cleaners that may damage the finish. Do not place the vacuum flask in a dishwasher unless the manufacturer states it is dishwasher-safe. Rinse and dry thoroughly with the lid removed to prevent odour build-up. Use for soups or dairy-based drinks with more frequent cleaning to avoid residue.
