Cap-Lock is a specially constructed plastic cap adapter precisely placed atop a syringe’s primary closure to equalize any difference in diameter between the syringe body and closure. Then, a label with integrated perforation for tamper evidence is applied so that it wraps around the syringe body and the bottom part of the cap adapter. When a user opens the syringe cap, the label is partially destroyed – clearly and irreversibly indicating that the cap has been opened. This enables the user to quickly and intuitively discern any possibility of product tampering, protecting patients against administration of potentially counterfeit substances.
Using Cap-Lock in everyday healthcare settings is designed to be easy, intuitive and safe: The syringe can be opened as usual and, due to the larger diameter, the adapter is simple to twist off even with gloves.
Cap-Lock from Schreiner MediPharm can be applied to syringes in a conventional production setting. Compared to shrink-wrap solutions, the application process requires no heat, making Cap-Lock also suitable for sensitive substances. The label can be provided with additional functionalities such as counterfeit-proof features, detachable documentation labels or light protection. The solution is adaptable to many commonly used syringe sizes, and both the label and adapter can be customized for color and design. Due to the combination of the adapter with the primary closure of the syringe, no additional waste is generated because both parts are firmly connected to each other.
