Adaptor for Alclad II bottles?

I find it easy to pour directly from the Alclad bottle into my airbrush bottles. It does not need to be thinned.  And it pours back into the original bottle if I have any left in the airbrush.

I saw some plastic bottles with the special tops at Hobby Lobby with the Iwata items. It looks like the top may fit the Alclad bottle so you can spray from the bottle itself.

 I just give it a good shake and pour it into the AB cup, no thinning required.
