Put it cover-up like in the second picture on your bench anvil, and press down on the teeth with your thumbnails. The arbor will easily pop the cover out.
I knew someone would have a better way, and I'm glad that it isn't some special-purpose Bergeon tool for $2000. Thanks for sharing this, I might try it! Your canned air might work for front-loading cases too...?
Certainly opening a barrel this way works, but please remember that it often distorts the lid of the barrel, so you need to check the barrel arbor end shake and adjust as required.
An alternative to the method described is to use canned air to open barrels - you just need to be able to fit the end of the tube over the barrel arbor, then give the trigger on the can a quick squeeze, and the barrel will pop open:

This works on barrels that don't have holes in them obviously, and the even pressure that the air applies to the lid tends to keep the shape of lid rather than create a cone shape that the method pf pressing the arbor on the bench will create. Doesn't work for all barrels, but whenever I can this is the method I use.
