Abstract (en)
A container suitable for containing a food or beverage comprises an insulating sleeve to which a thermochromic ink has been applied that indicates when the contents of the container have reached an acceptable temperature for consumption. Preferably the ink undergoes a reversible colour change over a range of temperatures, which may be either hot or cold. Preferably the insulating sleeve comprises an expanded polystyrene material, which is approximately 160 microns thick. Another preferable feature is a dispensing system comprising a thermostatically controlled cabinet in combination with one or more of such containers.
