Current PCO-1881 internal thread fits its external counterpart but it does not fit an actual PET bottle: The PET-bottle neck has a "lip" at its end with a somewhat larger diameter. Dminor of the internal thread must be made large enough to allow for this lip.
edit: the title is wrong, of course: Dminor is currently too small.
