Description

Vials and vial caps

technical field

The invention relates to the technical field of medical instruments, more specifically, to a vial and a vial cap.

Background technique

Vials, a small bottle sealed with a rubber stopper, are available in brown, transparent and other types, and are generally made of glass. The neck of the vial is thinner, and the thickness below the neck is the same; the mouth of the bottle is slightly thicker than the neck, and slightly thinner than the body of the bottle. Generally used as medicinal injection bottles, oral liquid bottles, etc., the seal is usually sealed with a rubber gasket, and finally the aluminum cap is crimped tightly by a capping device to achieve the purpose of sealing.
