Thermos thermal box THERMOS 4077341050 0.5 L, double-wall insulated food jar, blue

THERMOS 4077341050 is a 0.5 L double-wall insulated food jar in blue, designed to keep meals, soups and beverages hot or cold for up to 9 hours. The stainless-steel insulated body and leak-proof lid make it suitable for everyday use at work, school, or outdoor activities. Compact and durable, the jar provides a practical solution for transporting prepared food while maintaining temperature and hygiene.

Advantages

The double-wall vacuum insulation reduces heat transfer to preserve temperature for several hours without external condensation. The stainless-steel interior and exterior resist stains and odors and are easy to clean. The leak-proof closure prevents spills in bags and backpacks, while the compact 0.5 L capacity balances portion control with portability. Its robust construction supports repeated daily use.

Suitable for

• Hot soups, stews and porridge for work or school lunches
• Cold salads, yogurt and chilled desserts for picnics or travel
• Transporting baby food or single-portion meals
• Outdoor activities such as hiking or commuting

When it may not be suitable

This 0.5 L food jar is not intended for very large family portions or bulk food storage; users who need meals for multiple people or extended periods should select a larger container. It is not designed for microwave use due to its stainless-steel construction and should be opened carefully when contents are very hot to avoid scalding.

Key specifications

• Capacity: 0.5 litres

How to use

Preheat or precool the jar by filling it with hot or cold water for a few minutes, then empty and add your food to optimize temperature retention. Securely fasten the lid before transporting to prevent leaks. When serving hot contents, open the lid slowly to release pressure and reduce the risk of splashes. Clean the jar after each use following the manufacturer’s care instructions; hand washing is recommended for longevity unless stated otherwise by the brand.

What to consider before purchase

• Required portion size — 0.5 L capacity suits single meals or snacks
• Material preferences — stainless steel is durable but not microwave-safe
• Cleaning method — check if components are dishwasher-safe or need hand washing
• Intended use — consider how long temperature retention of up to 9 hours meets your needs

Usage recommendations

For best results, warm the jar before adding hot meals and cool it before adding chilled foods. Pack thicker dishes (soups, stews, porridge) for improved heat retention, and avoid carbonated beverages or highly acidic contents for prolonged periods to preserve seals and interior surfaces.
