Child-Resistant Tamper-Evident Caps

Child-resistant (CR) closures are designed to be difficult for young children to open but manageable for adults, usually through a push-down-and-turn or squeeze-and-turn action that needs two coordinated movements. Many markets require them on medicines, hazardous household chemicals, and cannabis and nicotine products.

Tamper evidence is the complementary feature: a tear band, breakaway ring or induction inner seal that is visibly broken once the pack is first opened. Our CR caps combine both functions in one closure.

We supply CR tamper-evident caps for OTC and prescription medicines, vitamins and dietary supplements, household and garden chemicals, cannabis and CBD products, e-liquids and nicotine, and automotive and industrial fluids. They close glass and plastic bottles and jars for both liquids and solid doses. If your product falls under child-resistant packaging rules, tell us your target market and we’ll point you to models with the matching test documentation.

Most of our CR caps use a two-part construction: an outer shell that spins freely until pressed down, engaging lugs on the inner cap that carries the thread and liner. The tamper-evident element is a tear band molded into the skirt, a breakaway ring, or an induction seal on the container mouth. Sizes cover 18 mm to 53 mm CT and special CR finishes, in white, black, standard colors or custom shades.

Child resistance is a property of the cap and container tested together, so the specified closure and finish should always be used as a pair and applied at controlled torque. Induction-sealed packs need the right liner, a flat container land and induction-sealing equipment on the line. Check after capping that the band is intact and that adults can still open the pack comfortably. We supply caps and matching bottles together so the pair stays consistent.

Inner and outer parts are injection-molded, assembled and lined, with tamper bands formed in the mold. Mechanism function, seal integrity and band reliability are our key in-process checks. Child-resistant designs tested to ISO 8317 are available — ask for the certificate for your chosen model and container. We mold caps in custom colors, print opening instructions on the top, and ship them bulk-bagged in cartons with finish and liner matched.
