What if...a collapsing bottle could maintain carbonation in soft drinks?

One of the greatest drawbacks in buying large volumes of soda is that the carbonation level of the product changes throughout the lifespan of the product. !”

A 2-L bottle of sparkling soda quickly becomes a mediocre 1-L of flat, unappetizing syrupy water that is destined for pouring down the kitchen sink.

Conventional thought is that the opening and closing of the package causes the soda to go flat. While this is a contributing factor, the main problem lies in the volume of headspace that is created in the package as the product is consumed. Carbon dioxide quickly migrates to the vacant space, causing the beverage to lose its sparkle.
