DS never went back to sleep after a bottle, he always was awake for about an hour.
I used to put him on his baby gym or in his swing chair or just play together and then wait for the yawns. As soon as I saw the first one i would wrap him etc and put him in his bassinette. Night times I would put him straight back in there with no play. Not that he would fall straight to sleep but at least he knew it was night time.
