Food Jar THERMOS STAINLESS KING 0.71 L, black double-wall stainless steel vacuum insulated

THERMOS STAINLESS KING 0.71 L food jar is a double-wall stainless steel vacuum-insulated container designed to maintain the temperature of hot or cold meals. With a 0.71-liter capacity and a screw-top lid, the jar is intended for transporting soups, stews, porridges and salads while limiting heat loss or heat gain during the day. The black stainless-steel finish offers a durable, easy-to-clean surface suitable for daily use at work, school or while traveling.

Advantages

The vacuum-insulated double-wall construction reduces thermal transfer and helps retain the served temperature for hours without the need for external power. The stainless-steel interior and exterior resist dents and stains and are suitable for regular washing; the screw-top lid creates a secure closure to minimize spills and preserve freshness during transport. The 0.71 L capacity balances portion size and portability, making the jar practical for single meals.

Suitable for

• Carrying hot soups, stews and porridge for lunch or on-the-go meals
• Transporting cold salads, yogurts or chilled dishes
• Use at work, school, commuting or short trips where temperature retention is needed
• Outdoor activities like picnics or day hikes where a compact insulated container is useful

When it may not be suitable

This model may not be ideal for very large family-style portions because the 0.71 L capacity limits the amount of food it can hold. It is not designed to replace full-size insulated coolers or warmers when storing multiple meals or large containers is required. Users who need microwave reheating should transfer contents to a microwave-safe dish, as stainless-steel construction is not microwave-compatible.

Key specifications

• Capacity: 0.71 liters
• Material: double-wall stainless steel with vacuum insulation
• Closure type: screw-top lid for secure sealing
• Colour: black exterior finish
• Intended contents: hot and cold meals such as soups, stews, porridges, salads

How to use

Preheat or precool the jar by filling it with hot or cold water for a few minutes, then empty before adding the meal to improve temperature retention. Fill the jar leaving some headspace to avoid overpressure with hot liquids, then screw the lid on tightly to ensure a secure seal. To serve, open the lid carefully and transfer contents to a bowl or eat directly from the jar if preferred. After use, wash the jar according to the manufacturer’s care instructions; hand washing is recommended if the lid contains seals or components sensitive to high dishwasher temperatures.

What to consider before purchase

• Confirm that 0.71 L capacity meets your typical meal portion needs
• Consider that stainless-steel construction is not microwave-safe
• Check whether lid components are dishwasher-safe if you prefer machine cleaning
• Assess portability needs — weight and size relative to your bag or lunch setup

Usage recommendations

For best results, preheat or precool the jar before filling and tightly close the screw-top lid. Avoid placing the jar in a microwave and clean any gasket parts regularly to maintain the seal and hygiene.
