I have the file attached. It’s coming so close, but I need to make the two surfaces flow into each other and seem like one piece. I will then join everything to make it a closedpolysrf.

You can see part of the cause for the problem on your screenshot. In some places, the swept ring has sudden change in curvature. This has to do with your rails being simple rectangles with rounded corners. I rebuilt two cross sections of the ring as degree 3 curves with 34 points and changed the curve seam to be at the underside of the ring. This way, you get a ring which consists of a single surface.
I trimmed the ring with an isocurve. The blend still wasn’t looking nice and I figured out the blend would benefit from a slightly different trim curve on the cylindric cap. I took the section of the ring which is inside the cap, oriented it roughly perpendicular to where the ring goes through the cap and scaled it a few times…

Do you happen to have a threaded inside surface for this bottle cap?
Mind posting an iges or Rhino5 file?
Thank you for your help! Yes there is more to the model as shown in this image, I just didn’t include the rest of the cap in the file
Here… Thank you!
