Joe F -

Actually the brand where I've most often encountered that particular pull-off foil seal is labelled prominently to show that they were awarded a "seal of approval" from the "Arthritis Foundation" or some such organization, for making it easier for "we of decrepit inclination" to get to the coffee.

For another brand, lacking the label, a proper grip with pliers on the seal foil, and holding the can down with both feet allows truly simple opening; but I have not bought that brand since learning the technique, since all flat surfaces (including chairs) where one's butt might be placed to position the foot on the can are covered (mostly with books or magazines and old mail) in our house - so the inconvenience of preparing a place for the opening exceeds the convenience provided by the alternate method of closure.

The small amount of coffee wasted in the can is probably insignificant in comparison to what some in my household will spill on the rare occasions when "someone else" makes a pot, although my usual brand now comes in a plastic (almost rimless) can, with foil seal, which opens easily and leaves very little in the can.
