The innovative lid alerts consumers their coffeetea may be too hot by changing from a dark coffee bean color to a bright red when the lid is applied. Secondly, the lid visually indicates whether or not it is securely attached to the takeaway cup, placing coffee house owners and consumers at ease regarding the safety concerns of hot coffee spillages. White lids offer no visual aids where the ideal consumption temperature for coffee is 152°f, while liquid burn hazards commence at 140°f. The aussie lid completes the color change at 115°f, allowing a &lsquored glow&rsquo to warn drinkers of the hot contents.
