The cap is reworked to be more air tight, and the clip shrunken down as much as possible without making it harder to use.
The tenth of those you have seen probably, but implemented all the good stuff. Snap lock lid, no printed threads, no screwing 3 turns, just snap it closed. Easy to open and close, no fiddling and breaking your fingers.
