I put a cottage cheese container of plastic in an old pressure cooker. I have a hose fitting screwed into the lid of the PC. I attach a hose from the lid to a device made by Fisher Scientific that has a threaded end for a garden hose. When a stream of water is forced through the device it causes a vacuum in the PC and pulls excess air from the plastic.

The extra plastic needed when pouring could be accomplished by having an extra-high gate which would hold a little more material than required.
