Medicine bottles, also known as vials and phials, are small containers used to store and dispense medications. Vials are typically cylindrical in shape and have a capacity of 5 milliliters or less, while phials are usually larger and can hold up to 10 milliliters of liquid. Both types of containers are made of glass or plastic and are designed to be airtight and leak-proof. They are commonly used in hospitals, pharmacies, and other medical settings.
