Exactly - some are perfectly fine. The cheap ones are terrible, crossthread too easily, get up in your face, dribble, or all of the above.

Sports style bottles solved the problem long before standard caps got in the game. They get disposed of together here either way, even if the cap gets yanked off for being stupid.

I don’t understand how they end up separate in disposal in the first place. The whole point is that you can reseal the bottle and move/store it without leaking. If you’re not actively using the bottle, it gets resealed to move or store. When you finish the bottle, you probably have the cap still in hand or very close by.

Tangentially, I’d love to see a Pfand type system here.
