22mm CRC Dropper Cap

This dropper cap is exclusively made in 400 thread size with precise machining tolerance. It connects firmly with matching bottle necks, effectively preventing thread slipping and loose fit after repeated screwing and unscrewing operations.

It applies professional CRC safety structure that must be pressed and twisted simultaneously to unlock. The design greatly reduces the risk of accidental opening by kids and avoids accidental ingestion of liquid contents inside bottles.

Structurally tailored to fit conventional Boston round bottles perfectly. It integrates leak-proof sealing, anti-volatilization performance and accurate dropper dosing function to meet safe packaging requirements for essential oils, extracts and chemical liquids.
