Abstract
A drinking cup includes an inner wall with an outer surface and an inner surface. The inner wall includes a thermo-chromatic substance that exhibits a color variance corresponding to a temperature variance in a beverage in the cup that is in contact with the inner wall. An outer wall is disposed about the inner wall that has a transparent area adapted to permit a visual perception of at least a portion of the color variance of the thermo-chromatic substance in or on the inner wall through the outer wall. A thermal insulation layer is disposed between the inner wall and the outer wall.
