What is an invention that improves the expiration date label to prevent disposal of waste food?

Approximately one-third of food produced worldwide is scrappedIt is clear that it is clear that the regions with the most food disposal by region are East Asia which includes Japan. A new way to solve such a food waste disposal issue is the International Design Competition sponsored by the James Dyson Foundation "James Dyson AwardsIt appeared in.

Industrial designersSolveiga Pakštaitė(22 years old) developed by "Bump Mark"Is a label that cleverly informs you of the expiration date of food using gelatin. This is a smart and simple label that is affixed to the packaging part of food, making it possible to notify visually impaired people of the expiration date of the food and is more accurate than the expiration date display currently printed on the package It is aimed at display.

The actual "Bump Mark" is a triangular design like this, just paste it in a package of food OK. When the feel of the label is slippery, the food is still fresh, so if you feel this feeling of decoction it is better to discard the food, tell the consumer the freshness of the food with the feel of the label That is why.


"Bump Mark" consists of four layers, the second layer from the top is made of gelatin and packed with the top and bottom plastic layers so that it will not leak from the label. The gelatin layer is designed to gradually soften in response to elements (temperature, oxygen, sunlight, etc.) when food is putrefying, and when the gelatin becomes soft, when the label is touched, from the top This will make it easier to understand the feel of the 3rd layer plastic deco bocco sheet, so it is better to discard the food as soon as it becomes clear.


In the following image, as shown in the illustration at the top of the image, as the food is fresh, the gelatin is hardened, when the freshness falls and it gets rotten, gelatin liquefies and you will be able to understand the feel of the decobedcoat sheet is.


It actually looks like this when put on food package.


This triangle label is "Bump Mark". It is compact and hardly noticeable.


The "Bump Mark" Kimo seems to have made a number of prototypes and tested since it is how well the feel of the deco is transmitted.


This is gelatin to inject into 'Bump Mark'.


Solveiga, the inventor of the idea says, "The only thing users should do is to feel the change in gelatin", and the difference in the shelf life depending on the type of food is adjusted by the amount of gelatin It is possible to do. In addition, although the existing expiration date management method uses electronic equipment, it is cited as one of the excellent points that cost is low because it does not require "Bump Mark" at all.
