Vacuum Flask THERMOS TC 0.35 L Blue, Stainless Steel Insulated Bottle

THERMOS TC 0.35 L Blue stainless steel vacuum flask is a double-walled insulated bottle designed to keep hot drinks warm and cold drinks cool. With a 0.35-litre capacity and a durable stainless-steel exterior in blue, this flask offers everyday thermal performance for commuting, office use, travel and outdoor activities. The screw-top closure helps prevent leaks while the compact shape fits many cup holders and bag pockets.

Advantages

The double-walled vacuum insulation reduces heat transfer to maintain beverage temperature for extended periods without external condensation. The stainless-steel construction provides resistance to impact and wear while preserving flavour by avoiding plastic contact with liquids. Its compact 0.35 L capacity balances portability and sufficient volume for a personal drink, and the reliable screw-top closure gives secure sealing for transport.

Suitable for

• Commuting and daily office use
• Short trips and travel
• Outdoor activities such as hiking or cycling
• School or campus use

When it may not be suitable

This flask may not be suitable when you need large-volume capacity for sharing or for long multi-day trips where higher litre volumes are required. It is not intended as a replacement for insulated coolers that include food compartments or for use with carbonated beverages under pressure.

Key specifications

How to use

Before first use, rinse the flask with warm water and mild detergent, then rinse thoroughly. To fill, unscrew the lid, pour the beverage without overfilling, and screw the lid back on until securely closed. Allow hot liquids to settle briefly before sealing to avoid pressure build-up. Clean after each use by handwashing the interior and lid; avoid abrasive cleaners and dishwashers unless the manufacturer explicitly states dishwasher safety.

What to consider before purchase

• Required capacity relative to your daily beverage consumption
• Whether a compact 0.35 L size fits your bag or cup holder
• Preference for stainless-steel construction and a screw-top closure
• Compatibility with your intended beverages (hot, cold, non-carbonated)

Usage recommendations

For best thermal performance, preheat with hot water or precool with cold water for a few minutes before filling. Handwash regularly and store the flask with the lid removed to prevent odours and moisture build-up.
