So i had this idea

[xxKDDxx]

I was thinking of trying to put my primed beer into collapsible water jug like the ones for camping. They have a spigot at the bottom that you unscrew to fill the jug. So im thinking I would prime the beer fill the jug, allow proper time to carb/condition, set in the fridge and fill glasses from it like a cask, I think it would collapse as it emptied to keep oxygen out. Im worried either that it is the wrong kind of plastic or that it would blow up from the pressure. Do you guys think it would work?

THere's a couple threads on here of folks using them with a beer engine. Look for the really big beer engine thread.

Im curious if I could just draw beer straight from the spigot into a glass

It doesn't seem worth it for one night when you could just use a 2 liter soda bottle instead. It's going to get flat by your plan and the jug won't collapse until it is flat as a pancake.

The keep the oxygen out is a good idea, but you need a rigid container and/or pressure in order to carbonate to any level at all. A self collapsing container with no makeup pressure will allow the beer to loose all it's carbonation over time. If you want a quick test, get a 2 litre bottle of pepsi, drink half, squeese out the air and screw the top back on to the semi collapsed bottle. In a day or two the volumes of CO2 will leave the pepsi and the pepsi will be flat. Flat pepsi is a shame, but not as bad as flat homebrew.

Im not trying to be difficult just curious. I dont understand where the co2 would go its in a sealed container. The gas would be on top of the beer and have no where to go. When the spigot was opened to fill a glass the co2 would have to push out all the beer to escape. I just dont get it.

In order for the beer to be not flat the CO2 has to stay in the beer. If there is no back pressure it will leave the beer and go into the space above it. If the space above it is not rigid it will expand and not create back pressure. lack of back pressure will let more leave the beer, then this vicious circle empties the CO2 from your beer until the beer is flat.

Ok im with you now. thanks for the help.
