I'm not sure if you want them in a container or packed, or what, but Doug Ritter shows in his own kit that he takes 6 rather large looking antibiotic pills from his doc and lines them up in a row and vacuum seals them into a nice looking little package.

There are some decent pill tubes which are waterproof on the market, I've seen some guys here use some of that new Saran wrap that's "sticky", etc. Maybe you could elaborate on what you are looking for?
