GL18 White Tamper-Evident Child-Resistant Closure with Integrated Vertical Dropper

The GL18 White Tamper-Evident Child-Resistant Closure with Integrated Vertical Dropper (GL18TECRCW-IVD) brings together the most demanding safety and dosing requirements of the GL18 system in a single cap assembly — combining a child-resistant opening mechanism, a tamper-evident ring, and a precision vertical dropper insert, manufactured in PEHD or PP with a PELD dropper insert. The vertical dropper delivers drop weight reproducibility of ±10% from the nominal target dose weight when the bottle is fully inverted to 180°, with a drop rate targeted at 60–120 drops per minute in line with European Pharmacopoeia monograph 0672. The child-resistant mechanism prevents unsupervised access by young children, and the tamper-evident ring provides visible first-open evidence confirming the product has not been accessed prior to purchase. This combination makes the GL18TECRCW-IVD the appropriate closure for regulated pharmaceutical oral drops, paediatric dosing formulations, licensed OTC liquid medicines, and concentrated nutraceutical preparations where precise dosing, child safety, and retail tamper evidence are all simultaneously required.

Each of the three functions operates independently within the assembly — the child-resistant mechanism governs access when the bottle is closed, the tamper-evident ring provides one-time first-open evidence, and the vertical dropper governs dispensing precision when the bottle is inverted. No single function compromises another, making this a genuinely integrated solution for the most demanding regulatory and commercial packaging specifications in the GL18 range. As part of the GL18 system (also known as NW18 or DIN168), the GL18TECRCW-IVD is fully interchangeable across all GL18 glass dropper bottles in the BlueSky range — 5ml to 100ml, in both amber and clear glass. For the correct dropper geometry to be specified for your formulation, BlueSky requires the liquid’s viscosity, surface tension, density, and target dose weight. Contact BlueSky to confirm stock availability, MOQ, child-resistant certification status, TE ring type, material choice guidance, and whether a self-seal membrane is incorporated in this assembly before specifying.
