Abstract
A drinking assembly has an external container having a container wall, an internal container positioned inside the external container, and a bottom cover that is removably connected to the bottom ends of the internal container and the external container. The diameter of the outer surface of the internal container is smaller than the diameter of the inner surface of the external container so that a gap is defined between the internal container and the external container when the internal container is positioned inside the external container.
