Abstract: A cooling inserted into a regular cooling chest as a unit. The cooling insert consists of a multiple of hollow panels that are hinged together at their edges by adhesive tapes or extruded layers on panels that are continued between adjacent panels. The hollow panels are constructed of thin walled plastic materials. A freezable substance is inserted into the hollow panels constituting a cooling medium that will permeate through the thin walls of the hollow panels to keep food and/or drinks in a cooled state.
