Ampoule: single dosage container made from glass sealed after filling by fusing the glass neck.

FromThe Medical Packaging Glossary

Ampoules are originally said to have been used for holding a small bit of people’s blood after they died. But today, they’re typically tasked for a much less gruesome mission – containing pharmaceutical hypodermic solutions or high purity chemicals that could be contaminated by exposure to air.

Ampoules are sealed by melting the top and don’t have a typical cap or cover, as most packaging does. Instead, the neck of an ampoule typically has scoring, a break ring, or a small cut to allow access to the contents.
