Do any plastic water bottles have this setup, and does anyone opt for this type of cap/valve with a squeezable bottle? Honestly curious. I presume the advantage the squeeze type bottle/cap is that you don't have to open close the top valve because it requires pressure to open the self-sealing valve, while with the free flowing valve you need to close after each drink (and open with your teeth?) or with every bump water will squirt out?
