I have problem with 0.5l yoghurt bottles. Yoghurt is best when shaken before opening the bottle because its viscosity spreads evenly, otherwise you get watery yoghurt on top, bottom is too dense.
I enjoy having morning breakfast in the park, drinking yoghurt straight from the bottle. When I shake it, yoghurt sticks to the cap. When caps were removable, I'd put it aside so that yoghurt that stuck to the cap does not spill on my shirt, re-screw it after I finish and throw bottle and cap to the bin. Now it's hard to remove the cap and I spill yoghurt on my shirt frequently, so I go to greater lengths to tear the cap away and re-screw when I empty the bottle.
