Thermos food jar Rockland ROCKET 500 ml, model R376

Thermos food jar Rockland ROCKET 500 ml, model R376 is a vacuum-insulated stainless-steel container designed to keep meals hot or cold while on the move. With a 500 ml capacity, this compact food jar fits typical portions of soup, stew, porridge or chilled dishes. The screw-top lid secures the contents and contributes to temperature retention, making the jar suitable for everyday use at work, school, hiking or travel.

Advantages

The double-wall vacuum construction reduces heat transfer to preserve the temperature of contents for extended periods. Stainless-steel inner and outer surfaces are corrosion-resistant and easy to clean. The compact 500 ml size balances portion capacity and portability, while the threaded lid provides a reliable seal to minimise leakage and maintain thermal performance. The cylindrical shape and smooth finish make it simple to fill and comfortable to carry in a bag or backpack.

Suitable for

• Hot soups and stews for work or school lunches
• Porridge and warm breakfasts on the go
• Chilled salads or desserts for picnics and travel
• Outdoor activities such as hiking, camping and day trips

How to use

Preheat or precool the food 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 without overfilling, leaving space for steam when storing hot contents, then screw the lid on tightly to secure the seal. To serve, open the lid carefully to avoid steam contact with skin. Clean the jar after each use by hand washing with warm soapy water and a soft brush; avoid abrasive cleaners to preserve the finish.

Usage recommendations

For best thermal performance, warm the jar with hot water before adding hot food or cool it with cold water/ice before adding chilled items. Do not place the jar in a microwave. Hand wash recommended to maintain the stainless-steel surface and insulation integrity.
