This innovative technology was first launched on the US market in 2004. Each container consists of an inner section filled with crushed limestone, the drink itself and a tight seal made of aluminium foil. Heat is released by removing the foil from the bottom and putting pressure on the lid. The ideal time for eating the food is indicated through colour coding. The robust container can be stored without refrigeration, and the soft insulating material ensures that a person’s hands stay cool while eating.
The same principle is applied to Hotcan ready meals where multi-layered cans, plastic bags or cardboard boxes serve to heat up the relevant dish. The available products cover a wide range, from pasta to vegetarian chilli. According to the manufacturers, their meals stay hot for around 45 minutes. Sounds okay, doesn’t it? Bon appétit!
