28mm Tamper Evident Dropper Cap

Tailored for 28mm large-caliber bottle necks to match mainstream syrup and oral liquid bottle specifications. It combines anti-counterfeit tamper proofing, leakproof sealing and dropper metered dosing into one all-in-one packaging closure solution.

Built with an integral breakable tamper ring. The security ring will rupture distinctly on the first opening, making unauthorized opening easy to detect, which safeguards product integrity during transportation, warehousing and sales circulation for pharmaceutical products.

Equipped with a precision-fit inner sealing liner. After being fully screwed tight, it effectively prevents leakage and inhibits syrup overflow or volatile deterioration, meeting the long-term preservation requirements of viscous oral liquid formulations.
