I just measured my Kraft 8oz container of grated Parmesan...2 3/4 inches.
Close enough?

Well, maybe close enough. That stuff in the Kraft can might qualify as
some kind of 'Parmesan-like substance', but I'd hestiate to call it
real Parmesan cheese. I'd only consider putting it on my pasta if I'd
had way too much wine to drink beforehand.


Here's a picture of some outflow valves as well as the pressure relief port that
Bob described. The outflow valve doesn't look like the cheese style one that
I was thinking of:

The cheese one sort of looks like a metal disk with triangles in it that are opened
and closed by rotating the triangles expose the underlying holes in the valve.

By the way, I actually have pictures of LongEZ cockpit vent that was literally the
top of a parmesan cheese can.
