FRESH LOCK is a redesign of the existing TETRA BRIK which is hard to suck through straw when there is only a little liquid in the pack and also hard to carry when being opened up.
People could insert both end of the tube into the 2 holes on the top that looks like to form a lock preventing leaking of the liquid and contamination, so that the pack could lock the juice inside to keep it fresh. When people would like to drink, they just need to pull out one end of the tube to unlock it. The hole remains on the surface allows air into the container for easy access of the liquid, which represent another meaning of unlock
