Cooling tray

摘要

A cooling tray includes a container, springs placed within the container to exerting a vertical thrust, a platform residing within the container and coupled to each spring, and a bowl for residing above the container. When ice is placed on the platform, the plurality of springs are each compressed such that the cooling material contacts an undersurface of the bowl. As the ice melts, the water flows below the platform, and the springs decompress and maintain the remaining ice in contact with the undersurface of the bowl. In this manner, food that requires refrigeration may be served from the portable cooling tray at the appropriate temperature. A formed ice block may be used to impart greater and more efficient cooling as a greater surface area of the ice contacts the undersurface of the bowl. The bowl may be of aluminum to further increase the efficiency.
