“Don`t throw me away”
A lot of consumers don`t rely on their common sense. They put the best before date on a level with the date of expiry. The new deposit bottle system informs the user about the freshness of the milk. This system also has an additional benefit for people who rely on their senses. By the range “Verarbeite mich” the consumers get animated to drink the milk before it gets sour.

The consumer is able to identify the freshness of the milk by comparing the colors.
