Accordion Style Soda Bottle

2 liter bottle collapses accordion style to save volume.

To save space, and CO2 in the soda, the bottle would collapse, step-wise and accordion style to allow for cuts in total volume as more soda is drank.

Accordion style.

Step-wise.

       The bottle would need to somehow be locked into the various states of crushedness, otherwise the pressure would just expand it out again. The release of CO2 out of solution in so doing would flatten the beverage.

       How about acme threads and o-rings ?   

       Actually, a significant crush-step reduction would probably resist most of the CO2 pressure, but I like my more complex variation.

       These pretty much exist for other usages, accordion to my memories of home darkroom chemical storage, all those decades ago.

       Can I please get some more bones for this crap I call a post?

       this seems like an excellent idea and I have never seen it baked in real ife so +   

       you might need to kick and punch the plastic for it to conform but hey, such is life.

       The cost of the extra packaging is not worth the soft drink it is preserving. And anyway why would a drinks maker want help customers extend the life of an opened soda, discouraging multiple gluttonous consumption.

       Maybe add some sort of screw post down the center to lock the bottle at different levels of crushedness.(+)
