‘Warm Disk’ maintains the warmth of drink or food for a long period of time by utilizing the heat of the container and food or drink without any power supply.
Other existing products for the thermal maintenance are large sized electric products.
Due to the power supply, existing products require power cables with less advantages for the portability, use or storage.
Since Warm Disk exchanges the heat by using the PCM material, no power supply or power cable is required so that very simple and safe use of product become available.
