Query: Like drinking from a Ball jar

Very uncomfortable for drinking. The ridges for the screw cap are right where you put your lips. It makes it uncomfortable and sloppy as it is prone to dripping. One of the ridges even has a slight chip making it even more unpleasant. I have a similar product from Tazo and cannot find another anywhere. It has a flat surface above the screw ridges - wish I could find another like it...
