Platy was standard pitch thread for a long time. I have some Platy bottles from 2001-2002 or thereabouts that have Coke plastic caps since such things are easy to lose. Seems like Platy changed the pitch in the mid/late 2000s (?).

Evernew (which I now use with Sawyer Squeeze) captive cap copied the design from a brand made in Austria around 1980 (I have 4 in the closet bought at LL Bean, red leash and green cap).

I've been following CNOC and it appears that some early production quality control issues have been worked out. Surely I'll get a Vecto sooner than later!

How about a Vecto with captive cap?
