It's a one way valve JAR! I buy a suitably sized mason jar, peel off the plastic valve from a donor coffee bag, drill a tiny hole in the lid of the jar and then glue the valve to the inside of the lid. Perfect! I then dump my freshly roasted and cooled beans into the jar and place in a dark, ventilated cupboard for two days. Finally, I transfer my degassed beans into a plastic coffee storage jar (one of those with the wine-pump oxygen extractor). I have a patented (I wish!) version of the one way valve bag.

Some points to add: Roasted and unroasted coffee should be kept in darkness. Vacuum bags with one-way valves are good for roasted coffee, and cotton drawstring bags for green beans. The humidity in Singapore is fine for green beans. It helps in the aging.

Putting in a one-way valve helps the roasted beans stay fresh in 3 ways. 1) Sunlight 2) Moisture 3)Oxygen. First 2 is obvious, as the bag provides this barrier. For oxygen, it is the release of the carbon dixoide that drives/dilutes the oxygen out of the bag. Alas coffee by its complex nature never makes it for us.. some beans do require resting more days for the flavour to develop and evolve.. Something to point out..
