Abstract: A portable container (10) for receiving contents for transport while regulating the temperature of the contents includes a combined heater and/or cooler in the form of a Peltier effect device (50), a removable inner receptacle (70) for receiving the contents, an air gap around the outside of the inner receptacle, and a control unit (62) for controlling the Peltier effect device so as to regulate the temperature of the air around the outside of the inner receptacle and thereby regulate the temperature of the contents of the inner receptacle. The control unit can have a temperature logging system for recording the temperature history of the contents of the container.
