It's a tiny delicate vial which I do not want bouncing around with the toothpaste etc in the bag, so I am hoping it is OK to box it up and leave it among my clothes in the carry-on.
Thanks.

If it's not in your 311 baggie you are supposed to declare it.
If it's a tiny vial they probably won't see it, though. I got to the point that I wasn't bothering to declare a whole box full of 5ml ampules (for a total of nearly a liter of liquid) because I realized the x-ray didn't see them.
