You can rotate the bottle before taking a sip to position it such that the cap doesn’t hit your face.
And gravity will make the cap spin around, hit your face, get in the way of the liquid, and make it splash everywhere but your mouth.
You can also pour liquid out of the bottle without having it run into the cap using the same rotation technique before pouring.
Same issue. As soon as you tip the bottle the cap will spin (apparently whatever genius designed this useless annoyance didn’t realise that bottle necks are cylindrical), get in the way of the liquid, and make it spill everywhere but the container you’re trying to pour it into.
They’re like a Pythagorean cup without the temperance lesson and well thought out design.
The only way to use these without wasting 99% of the liquid and making a mess is to either awkwardly try to hold them up as you pour, or to violently rip them out before pouring in an entirely justified fit of righteous rage.
What an utterly infuriating waste of plastic, time, and money.
