Contact the source, it means the seal was not tight enough and the crimpers need to be adjusted.
If the vial is sealed tight, the tops are cheap and too thin.
Cheap crimp on caps are usually the reason. The really cheap caps aren't much more than formed foil.I've never had it happen before now. Wondering if I should be concerned about the source or if it's just a fluke thing. Seems like the vial is more open to contamination now since it can't be re-sealed.
