A rubber ring that fit in the cap would work. But it would have to be the right size.
I had thought also maybe I had overtightened the top also (I had even resorted to using those rubber grip things to tighten the top with no avail), but then I got a new bottle and purposefully did not overtighten - leaked just the same. A rubber ring or gasket is a thought, although I guess it would have to be safe for drinking. Hmmm. . .
