  • known sorption cooling elements provide a successful tool for chilling liquid receptacles as cans or bottles, some important problems remain yet unsolved in the state of the art, specially from the user's point of view.
  • known sorption cooling elements are not equipped with heat isolating mechanisms capable of not only providing a more efficient cooling process in terms of energy requirements and cooling power, but also ensuring the integrity for the user by isolating the sorption components which, during the cooling process, can acquire high temperatures, with the corresponding risk for the consumer.
  • the present invention is aimed to solve the above-referred problems of the state of the art by means of a self-chilling container based on a flexible sorption cooling element wrapping a liquid receptacle and surrounded by an inexpensive heat-insulating external casing.

  • Another object of the invention is to provide a simple self-chilling container capable of maximising the effective heat-exchange contact surface with a liquid receptacle by means of a flexible sorption cooling element, while thermally isolating the sorption elements from the user in a risk-free way.
  • Another object of the invention is to provide a specific flexible sorption cooling element configuration capable of achieving cooling powers higher than 80 W, using inexpensive materials, and that can be manufactured at a fully automated production line.
