The Fresh Shrinking Jug keeps milk from turning sour

We know milk is notorious for going bad without any warning. People who can’t get through their cartons in one day are quite aware of this problem. The Fresh sinking milk jug seems a good solution to this. It is a spring-loaded jug with flexible sides. What you need to do is pop it out to its full height to fill it and then close it with the airtight lid. After this, press the release valve and push down on the lid until the milk starts pouring out the nozzle. Then just release the valve button and the milk is safely sealed in the jug again. This avoids contact with oxygen. Keeping it chilled and the lack of oxygen slows down the process of the Lactobacillus bacteria of making the milk turn sour. So far it isn’t in production, but the idea id great and it ought to be.
