Yeah, turning it a bit to the side is no big deal.
However, I recently found out that this makes drinking things a little more viscous absolutely impossible without messing up your shit.
I drank a Kefir, which you normally shake before drinking. So there is a lot of it clinging to the inside of the cap for dear life - up until to that very moment you take a sip. Then, it decides that it had enough and spills on your clothes, face, shoes - whatever the fuck it can possibly get to.
So either you need a glass, let it sit until the cap is mostly empty or lick that cap and look like a complete degenerate.
Yeah, iirc TetraPak advertised as being an eco-friendly packaging and was prohibited to do so (at least in some countries, dunno) exactly because of that.
