Those bottles are called a Boston Round. Not sure if there's a better source for the caps, but Amazon has them for $0.39/each (if you buy 12 dozen of them.)

This is what I do. I fill the preform with 50% yeast from a starter that I’ve overbuilt and then top it off with a 50/50 solution of wort/food grade glycerin.
For management I slant 4 preforms for every new yeast I get. One goes to my Homebrew buddy who only uses dry yeast, one gets a different color cap, two get white caps and all labeled with month/date created and on the cap labeled with just the yeast info.
When I want to make a stater I pull out the preform two days before I’d normally would (they take longer to get started).
I still wash a yeast if I think I’ll use it within the year and it’ll go in the fridge in a mason jar.
Once I get to my last preform (different colored cap) I re-overbuild that yeast and restart.

That is exactly how I wash all my boston rounds. I want everything that comes my way to get a thorough washing, and I know a lot of people here are weird about soap. I fill up a big pot with water, with the boston rounds standing up inside, then put it on the stove and let it boil. Like u/FlavSec says, I just turn it off when it gets violent and they start clinking.
While those are boiling I let the caps all soak in hot water, and maybe switch out the water a few times to keep it hot. I find the caps are the ones that still retain a faint peat smell sometimes, so I will either only reuse those for peated Scotch, or if it's bad enough I have a bag of caps and would just replace it. I think the bag of caps is good to have anyway, to replace a broken one or those shitty flat gasket ones.

Like u/fuckernaut said soda preforms. You can reuse the preform and buy replacement caps. I’ve also though about using 4 oz mason jars since everything is reusable.
safe as it was new. just a protip, you can pickup a 'cork' that fits the 14mm joint size easily, to avoid needing rubberbands etc...
