When I was a kid in the 70s my parents taught me that any bottle with ridges on the side was poisonous. Whatever happened to such bottles having ridges nowadays? It just occurred to me that most don't now. It used to be a thing that anything dangerous had such bottles so everyone including blind people knew the contents were bad.
Baked beans and bitrles water has ridges

Plastics and materials not stronger so dont need the same reinforcing ridges
