I also welcome ~gd's comments here, especially if he has additional facts on the matter.
Air is only about 20% oxygen, most of it is nitrogen--O2 absorbers don't make the air "go away". Oxidizing metal doesn't create a vacuum, it is a chemical reaction. A chemical reaction within a sealed container can't make atoms disappear.
