One can certainly do as you have suggested and many do; there is an extended
conversation about this in the archive somewhere. The gas will push the lid
up and escape and when there is a negative pressure it will draw the lid
closed ... or something like that.
This is for those of us that suffer with the terrible affliction known as
CRS (Can't Remember Shtuff). Right after roasting, I put the lids on with
the band tightened, put it in the coffee cupboard and forget about it ...
like I was going to do anyway! Seriously, I have "found" coffee in there
that I roasted 3 weeks prior and had no recall ... company enjoyed it
Generally after a couple of days, I vacuum seal the jars, but this is just
my preference. The beans do continue to out gas for a days, with a large
volume of it being on the first day. I get the valves off of used coffee
bags of any brand or variety ... they usually just peel right off.
