Markings for no chill cube?

[Honk]

I've just picked up some reverse osmosis water from an aquarium place near me. Will the container it came in double up as a no chill cube?

Triangle recycling mark on bottom of the container has "02" I'm it.

Hi!
It's HDPE, so it's perfectly safe: https://learn.eartheasy.com/articles/plastics-by-the-numbers/

Thanks @Bigcol49 perfectly safe might be a bit of an exaggeration when I'm brewing, but at least I know the plastic is ok.
