I've used that technique with phenolic (Bakelite) screw-capped vials.
Air bubbles form in the vials so that in a few years the vial
contents have dried even thought the outside container has plenty of
fluid remaining. After a decade or more, the caps expand and slip off
the vials -- specimens become mixed in the bottom of the outside jar.
These days I store the vials right-side up in jars of 70% alcohol
with PE/PP lids. Phenolic caps have been discarded and vials are
loosely plugged with cotton.
