dropper cap

A dropper cap functions as the closure and dispensing interface for glass pipette droppers used in serum and essential oil packaging. The cap style—such as a screw cap or aluminum collar—determines the visual character and how the assembly seals against the bottle neck. When specifying a dropper cap, buyers should confirm the neck finish matches the bottle opening and consider the bulb material and color, pipette length and tube diameter, and tip structure to suit the formula viscosity and desired drop size. Decoration options and component compatibility should be verified with physical samples before production.
