1. A thermochromatic label system for providing an indication of a temperature condition of contents of an inner volume of a vessel through convective heat transfer, the thermochromatic label system comprising:
a thermochromatic label comprising a facestock with a first surface comprising a thermochromatic display surface and a second surface, a pattern of adhesive disposed on the second surface of the facestock, and a thermochromatic image disposed on the thermochromatic display surface of the facestock, the thermochromatic image comprising a thermochromatic material with an active temperature range;
a vessel with an inner volume for retaining vessel contents in a temperature condition; and
a lid for the vessel wherein the lid has a lid surface and a protuberating, preconfigured label retention structure within the lid surface for retaining the thermochromatic label, wherein the label retention structure comprises a raised protuberance on the lid, wherein the label retention structure defines a raised sub-volume within the lid and above the inner volume of the vessel when the lid is applied to the vessel;
whereby the temperature condition of the vessel contents can be sensed and indicated by the thermochromatic label through convection without requiring direct or derivative conductive contact between the vessel contents and the thermochromatic label.
