A metallic can end for a container is described. The metallic can end has a curl defining an outer perimeter of the can end. A wall extends downwardly from the curl. A strengthening member is joined to a lowermost end of the wall. A center panel is joined to the strengthening member and is centered about a longitudinal axis. The center panel has a product side and a public side. A rivet is located on the center panel. A displaceable tear panel is on the center panel. The tear panel is at least substantially defined by a frangible score and a non frangible hinge segment. A non-detachable tab is staked to the center panel by the rivet. The non-detachable tab has a nose end extending over a portion of the tear panel, a lift end opposite the nose end, and a central webbing between the nose and lift end. The webbing has a hinge region and a rivet island surrounding the rivet. The rivet island is at least partially surrounded by a first void region to provide a first exposed area of the center panel. A first temperature indicator has a first thermochromic material which undergoes a color change upon reaching a first predetermined temperature. The first temperature indicator is located on the non-detachable tab.
