Bottle and Cap Thread Design

Hello all,


I have a glass bottle and a custom cap in which I'm trying to make matching threads. I have already done the threads on the bottle, so the problem that arises is the internal threads for the cap. I modeled the internal threads using the same thread measurements as I did with bottle threads. But when I take a cross section of the cap and bottle together, I see that the threads of the cap and bottle don't contact. I've tried to modify the cap several times to no avail.


I'll appreciate any suggestions/ideas.
