Food Jar THERMOS FUNTAINER 0.3 L — double-wall stainless steel insulated container, Mermaid design

THERMOS FUNTAINER 0.3 L food jar is a double-wall stainless steel insulated container designed to keep meals at a stable temperature while you're away from home. The compact 0.3 litre capacity and durable construction suit hot or cold foods such as soups, stews, porridges and baby food. The Mermaid design provides a decorative exterior while the interior focuses on thermal performance and ease of cleaning.

Advantages

The double-wall stainless steel body provides thermal insulation to slow heat loss or heat gain, helping food stay warm or cool for several hours. The compact size makes it easy to fit into backpacks, lunch bags or diaper bags, and the stainless interior resists stains and odors. The screw-top lid closes securely to reduce spills and the robust exterior withstands daily use.

Suitable for

• Keeping soups, stews and broths warm for meals at work, school or on the go
• Transporting porridge or cereal for children's lunches or baby food
• Carrying chilled salads, yogurts or fruit that benefit from insulation
• Short trips, commuting, picnics and day outings where compact food storage is needed

When it may not be suitable

This 0.3 L food jar is intended for single-portion meals and is not suitable when large-capacity food storage is required. It is not designed for long-term freezer storage or for use in a microwave oven; using it in the microwave may damage the container and is unsafe.

• Material: double-wall stainless steel (interior and exterior)
• Thermal insulation: vacuum/air-insulated double wall construction

How to use

Preheat or precool the jar by filling it briefly with hot or cold water, then emptying before adding food to improve temperature retention. Fill with freshly prepared food, close the screw-top lid until it is snug, and transport in an upright position when possible. Clean after each use following the manufacturer’s care instructions; typically hand washing the lid and rinsing the stainless interior prevents residue buildup. Avoid using abrasive cleaners that could damage the finish.

What to consider before purchase

Usage recommendations

For best results, warm the jar with hot water before filling with hot food and close the lid promptly. Store upright when possible and clean regularly to maintain thermal performance and hygiene.
