Some people, especially elderly, either forget or don’t care enough to look at the expiry date of their medications, but some chemicals can lose potency over time and may even become counterproductive. Designers Kanupriya Goel and Gautam Goel propose a new design for pill blister packs that will display a message not to take the drugs once enough time passes.
The material would consist of two layers, with the top containing the original drug’s info label and a bottom layer with ink that slowly seeps into the top. After enough time passes, the warning message will become clear and the patient will immediately know to get a fresh refill. The Self Expiring, as the design concept is called, won a 2013 red dot design award.
