I've never done it, but I suspect most of those caps that are "sealed" to the bottle could be pried off using something like channel lock (also called water pump) pliers. Use a twisting and upward prying motion. You might even be able to get a screwdriver sort of underneath the bottom edge of the cap, and pry/bend it upwards to loosen, then get it the rest of the way off with pliers. Just be careful not to go at it too rough and break the glass, though even then if that's what it took to get the bottle open, I suppose any glass in the juice could be strained out.
You may also be able to use an electric drill with a smallish drill bit, and drill down through the atomizer from the top, later straining out any drilled cap bits that might get down into the juice.
This is the stuff I'd try if I really wanted to salvage the cologne. Then I would put the stuff in a different container and use it as a splash frag, or I know online you can buy spray atomizers for perfumes and things, and you could get one of those and pour your juice into one of those. Again assuming you can pry off that bad spray cap.
Someone on here once posted a link for a site that sold vials, spray bottles, and other accessories of interest to fragheads.
