The squeezable upside down ketchup bottles have already solved this to my satisfaction.
I need someone to solve the other great issue our times, how to preserve the fizz in a 2 litre bottle of coke after you consume part of it.
- saycheese 10y agoThat's been solve too, just not designed into the bottle; there are plugs that let you pump pressure back in the bottle.

- sp332 10y agoI don't really see this working. There's not enough CO2 partial pressure to maintain carbonation, and I really doubt there's enough air pressure in the bottle to force very much air into solution.
- alphapapa 10y agoIt does work. Been working for decades. :) You pump it until the bottle is firm and nearly unsqueezeable, and it keeps it fresh.
- CraigJPerry 10y agoAfter pouring, crush the bottle enough to dispel most of the air so that the fluid is a few mm from the cap and replace the cap tightly.
- FreeFull 10y agoThis doesn't help at all, unless you take steps to keep the bottle from uncrushing as carbon dioxide inevitably comes out of solution. What does help is keeping your drink refrigerated, because gases dissolve better in cold water than in hot.
- barking 10y agoSo if you do take steps to prevent the bottle from uncrushing would it work then? Some sort of a simple vice, perhaps?
- FreeFull 10y agoRight, then as the carbon dioxide pressure builds, it'll reach equilibrium sooner, so not as much will end up out of solution.
- CraigJPerry 10y agoHere's how I reasoned about this, but this isn't my forte and I'd welcome any corrections! The pressure of gas in the bottle neck increases as degassing occurs but only until an equilibrium is reached. The equilibrium occurs at a pressure lower than that required to deform the tough plastic in the neck of the bottle and lower than that required to overcome the soft bottle body plastic connected by hydraulic advantage to the gas via the small cross sectional area of fluid in the bottle neck.
- 725686 10y agoNot only this doesn't help, it makes it worse. As the bottle tries to recover it's original shape, it sucks the carbon out faster.
- Gravityloss 10y agoNot necessarily, if the bottle is very flexible.
- aristus 10y agoAh, that's easy: don't store carbonated drinks in the door of your fridge. Every time you open the door it shakes them and releases gas from the liquid. Try it!
- Declanomous 10y agoFurthermore, the door is the warmest place in a fridge. The carbon dioxide will stay in solution better if the pop is kept colder. Similarly, recap the pop and put it back in the fridge after pouring a serving.
- 50CNT 10y agoDo the second best thing and build a small carbonation rig.
