As a youngster I have forgotten plastic soda bottles in -30 and they have swollen badly. I remember warming them on the dash and it taking several hours to get it all liquid. The brown liquids would melt out leaving white ice for the last. I think the bottle would be stout enough to handle -25 to 10 easily but -25 to 72 is almost 100 degrees of rapid change. The outside molecules expanded faster as they had the quickest temperature change.
