Abstract
A beverage container having an inner core and an outer shell, relatively rotatable such that a spiral groove in the inner core can be rotationally aligned with cooling flanges on the outside of the outer shell for cleaning, or rotated to close the cooling flanges, forming a cooling tube from the inside of the inner core to a drinking tube at the top of the container, thereby cooling a beverage that is drawn through the cooling flanges by radiating heat into the ambient environment.
