These days, with so many other things to think about, trying to keep track of food which only stays fresh for a certain number of days can be difficult. The freshness indicator changes colour to remind users of the useby date. The freshness indicator is made primarily of epaper and is attached to a consumable product with a loop of elasticlike cord. The timer is pressed when the product is first bought, with the number of presses equalling how many days the product is expected to stay fresh. Five presses, for example, would equal five days. Over the course of those five days, the indicator changes from green to red, with green symbolising fresh and red symbolising expiry. This makes it very easy to see if a product is in danger of expiring, and also makes choosing which of any similar products should be consumed soonest if they have been bought at different times. As well as the daycounting function of the freshness indicator button, the cord length can be adjusted and locked so it can be fixed on food or food packaging boxed, bagged or bottled.
