Can Water Bottles Explode?

Previously, the water bottle would normally have a hole in its bottom for air to pass through while being filled. But with pressure based closures, this system seems to have reached the limits of its usefulness. Increased restriction on the neck or expansion at the top can both cause problems while filling up a container that has no venting capability under these greater-than-usual pressures.
Moreover, where you are really pushing it is if plastic comes into contact with freezing temperatures because then hydrogen gas molecules get squeezed out of their microscopic pockets within the plastics and create airspace where there was none before. The trapped gas then expands when exposed to higher room temperature levels and could gradually push outwards against external structures.
