Need to keep your food warm (or cold) for a few hours? Our designers have developed this simple and lightweight stainless steel isothermal box.
How is thermal insulation tested?
We tested this food box in the laboratory, in accordance with standard EN 12546-1, at an ambient temperature of 20°C while it was filled to its full capacity. The time taken to go from 95°C to 50°C (the temperature of food that feels hot enough to eat) is 16 hours.
Advice for maximising the performance of your isothermal box.
Fill your food box with hot water for 5 minutes then replace the water with your hot food. Close the box.
The fuller the box, the more effectively it keeps its contents hot or cold.
How does the isothermal element work?
We use a double stainless wall with a vacuum between to block thermal exchanges by conduction or convection. To block exchanges by thermal radiation, a fine layer of copper covers the outside of the inner wall.
The top is insulated thanks to an internal insert made from expanded polystyrene.
Functions
Discover your 2-in-1 meal companion. On top, a generous 0.8L space for your carbohydrates and vegetables. Below, a 0.4L compartment that is perfect for your proteins.
A practical handle for taking it everywhere, and an elastic loop for storing your cutlery.
Do not place the box in the microwave.
Care tips
Dishwasher safe product (lid + body). Warning, in this case do not lose the top seal. Dry with the top off. The seal and handle can be removed for a complete wash and dry.
First use
Rinse the entire product 3 times with clear water before using for the first time.
Materials and regulations
Our products and materials meet the food contact standards in force. They do not contain Bisphenol A (BPA) in accordance with the French regulations in force.
We have chosen to use 18/8 (304) stainless steel for the tank, recognised for its food safety and a heat and shock resistant polypropylene for the top. The seal and handle are made from silicon, an extremely durable material.
Top tips...
As well as keeping food warm, you can also keep it chilled on your hikes. There’s nothing better than a spoon of ice cream halfway through your walk to motivate the kids (and the grown-ups!).
You can also use your box as a yoghurt maker: Bring the milk to the boil, leave it to cool down to around 43°C (warm but doesn’t burn), then pour the milk into the box with a spoon of yoghurt. Close the box and leave overnight (between 6 and 10 hours).
