Grind a fine U-shape into the lid base and find a thin enough oring that fits the groove with a lower hardness rating, lil dab of bonding on the very bottom of the U in a few spots, and that's about it. Won't hold any pressure but at least won't leak while washing your hands. You might have until you open and close it a couple hundred times before needing to rebond or replace the oring.
Also make sure whatever metal the ring is made of isn't toxic to leech into any meds stored. Takes the name poison ring to even further
