Thanks zarkow!

@Andrew - will zarkow's results above work for you? That's using the Loft style = "Loose" option in Loft which is a lot more tolerant of changes in direction than the regular loft. With the loose style loft the surface is more gently guided by the profile curves instead of being forced to go directly through them and is less prone to stressed and buckled areas.

@Michael Thank you for the pro tip, I will try make some more attempts remembering your guides. Much appreciate:)

@Zarkow Once againg, thank you! Thats almost, what I`m looking for:-P Almost, because there is still this ugly pinch where two harde dges collide. At the original bottle, its completly smooth. But seriously: thank you! I`ll try to make some new tries with Michels and yours help:)

...oooor you try the MoI Sub-D way:
