Those containers should serve you well. As PR suggested, just limit how much you store, because no matter what you have your beans in past 10 days, you'll notice a decline in flavors. The CO2 that's in the beans after the roast... as it leaves the bean, it allows the favorable chemical compounds that produce the flavors to come together... so during the rest/de-gassing time, flavors will improve each day. The rest time needed for flavors to peak will vary from one coffee to the next, as well as with the roast level - darker roast, less rest/lighter roast, more rest. So if a coffee needs 4 days to peak, and it has a 6 day plateau where the flavors are best, it'll begin to age and get stale from then out. Your containers will be airtight and will help delay and slow down that staling process (which is mostly the interaction of oxygen w/ the bean) but still, bear in mind that a couple week's worth of coffee is all you really want on hand if it's convenient enough to buy often and in small amounts.
