Thermos food jar ORION Cosmos 0.5 L - insulated lunch container, stainless steel interior

ORION Cosmos 0.5 L food thermos is an insulated lunch container designed to keep meals hot or cold for several hours. The 0.5‑liter capacity is suitable for single portions such as soups, stews, porridges or chilled snacks. The thermos features vacuum insulation and a stainless steel interior with a wide mouth for easy filling, serving and cleaning. Its compact shape and screw‑top lid allow secure transport in a bag for work, school or outdoor activities.

Advantages

The vacuum insulation minimizes heat transfer and helps maintain temperature of food and beverages. A stainless steel inner surface resists staining and is suitable for acidic and hot foods. The wide mouth simplifies adding solid ingredients and utensils, while the screw lid provides a reliable seal to reduce leaks and spills. The 0.5 L capacity balances portability with enough volume for a single full meal.

How to use

Preheat or precool the thermos by rinsing it with hot or cold water for a few minutes before filling to improve temperature retention. Fill the thermos with hot or cold food, leaving a small headspace before closing the lid tightly. For best thermal performance, fill with food at the desired serving temperature and keep the lid closed until use. Clean the interior after each use using warm water and mild detergent; rinse thoroughly and allow to dry with the lid removed.

Usage recommendations
