Abstract: The instant invention provides a liquid container that may be configured as an insulated container or vacuum flask. The liquid container may indicate the temperature and remaining amount of liquid within the container. The liquid container may include a housing surrounding a beverage compartment in fluid communication with a transparent tube. A float may be retained within the transparent tube by stop elements located at the top and bottom of the tube. A graduated scale may be located on the exterior of the housing and associated with the float to indicate a liquid level within the beverage chamber. The float may be configured as a temperature-sensitive spherical element that indicates the temperature of the remaining beverage in the container. A cholesteric liquid crystal deposit, luminescent or fluorescent material that changes color or emits light in the range of 60.degree. to 212.degree. for a beverage such as hot coffee.
